  • JMS ConnectionFactory creation error WSVR0073W

    - by scottyab
    I must confess I’m not a JMS aficionado, one of our guys has written a Java webservice client [postcode lookup web service] and from a Remote Java client are calling a Message Driven Bean running in Websphere 6.1, using JMS. Getting the following error when attempted to create the Connection Factory. To which configured within Websphere jms/WSProxyQueueConnectionFactory. WARNING: WSVR0073W. Googling WSVR0073W yields little, the error code is an unknown error. Can anyone shed any light on potential issues creating the connection factory.

  • JAXB + JAK java.lang.ClassCastException

    - by Ivansek
    Hi, I read page about JAK implementation where is a piece of code from pom.xml file (Listing 1). This piece of code is actually commented in pom.xml file so i uncommented it in order to add my own schema to compile. After that i run command mvn -e clean install, and i get this error: ivansek ~/Sites/Xlab/KMLTest/javaapiforkml-read-only $ mvn -e clean install + Error stacktraces are turned on.

  • Visitor and templated virtual methods

    - by Thomas Matthews
    In a typical implementation of the Visitor pattern, the class must account for all variations (descendants) of the base class. There are many instances where the same method content in the visitor is applied to the different methods. A templated virtual method would be ideal in this case, but for now, this is not allowed. So, can templated methods be used to resolve virtual methods of the parent class? Given (the foundation): struct Visitor_Base; // Forward declaration. struct Base { virtual accept_visitor(Visitor_Base& visitor) = 0; }; // More forward declarations struct Base_Int; struct Base_Long; struct Base_Short; struct Base_UInt; struct Base_ULong; struct Base_UShort; struct Visitor_Base { virtual void operator()(Base_Int& b) = 0; virtual void operator()(Base_Long& b) = 0; virtual void operator()(Base_Short& b) = 0; virtual void operator()(Base_UInt& b) = 0; virtual void operator()(Base_ULong& b) = 0; virtual void operator()(Base_UShort& b) = 0; }; struct Base_Int : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; struct Base_Long : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; struct Base_Short : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; struct Base_UInt : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; struct Base_ULong : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; struct Base_UShort : public Base { void accept_visitor(Visitor_Base& visitor) { visitor(*this); } }; Now that the foundation is laid, here is where the kicker comes in (templated methods): struct Visitor_Cout : public Visitor { template <class Receiver> void operator() (Receiver& r) { std::cout << "Visitor_Cout method not implemented.\n"; } }; Intentionally, Visitor_Cout does not contain the keyword virtual in the method declaration. All the other attributes of the method signatures match the parent declaration (or perhaps specification). In the big picture, this design allows developers to implement common visitation functionality that differs only by the type of the target object (the object receiving the visit). The implementation above is my suggestion for alerts when the derived visitor implementation hasn't implement an optional method. Is this legal by the C++ specification? (I don't trust when some says that it works with compiler XXX. This is a question against the general language.)

  • Getting EOFException while trying to read from SSLSocket

    - by Isac
    Hi, I am developing a SSL client that will do a simple request to a SSL server and wait for the response. The SSL handshake and the writing goes OK but I can't READ data from the socket. I turned on the debug of java.net.ssl and got the following: [..] main, READ: TLSv1 Change Cipher Spec, length = 1 [Raw read]: length = 5 0000: 16 03 01 00 20 ....

Am I doing something wrong with the socket or with the SSL authentication? Thank you.

  • Single DispatcherServlet with Multiple Controllers

    - by jwmajors81
    I am trying to create some restful web services using Spring MVC 3.0. I currently have an issue that only 1 of my 2 controllers will work at any given time. As it turns out, whichever class comes first when sorted alphabetically will work properly. The error I get is: handleNoSuchRequestHandlingMethod No matching handler method found for servlet request: path '/polinq.xml', method 'GET', parameters map[[empty]] I had a very simliar message earlier also, except instead of the map being empty it was something like map[v--String(array)] Regardless of the message though, currently the LocationCovgController works and the PolicyInquiryController doesn't. If I change the change of the PolicyInquiryController to APolicyInquiryController, then it will start funcitoning properly and the LocationCovgController will stop working. Any assistance would be greatly appreciated. Thank you very much, Jeremy The information provided below includes the skeleton of both controller classes and also the servlet config file that defines how spring should be setup. Controller 1 package org.example; @Controller @RequestMapping(value = "/polinq.*") public class PolicyInquiryController { @RequestMapping(value = "/polinq.*?comClientId={comClientId}") public ModelAndView getAccountSummary( @PathVariable("comClientId") String commercialClientId) { // setup of variable as was removed. ModelAndView mav = new ModelAndView("XmlView", BindingResult.MODEL_KEY_PREFIX + "accsumm", as); return mav; } } Controller 2 package org.example; @Controller @RequestMapping(value = "/loccovginquiry.*") public class LocationCovgController { @RequestMapping(value = "/loccovginquiry.*method={method}") public ModelAndView locationCovgInquiryByPolicyNo( @PathVariable("method")String method) { ModelAndView mav = new ModelAndView("XmlView", BindingResult.MODEL_KEY_PREFIX + "loccovg", covgs); return mav; } } Servlet Config <context:component-scan base-package="org.example." /> <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver" p:order="0"> <property name="mediaTypes"> <map> <entry key="atom" value="application/atom+xml"/> <entry key="xml" value="application/xml"/> <entry key="json" value="application/json"/> <entry key="html" value="text/html"/> </map> </property> <property name="defaultContentType" value="text/html"/> <property name="ignoreAcceptHeader" value="true"/> <property name="favorPathExtension" value="true"/> <property name="viewResolvers"> <list> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> </list> </property> <property name="defaultViews"> <list> <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView"/> </list> </property> </bean> <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" /> <bean id="XmlView" class="org.springframework.web.servlet.view.xml.MarshallingView"> <property name="marshaller" ref="marshaller"/> </bean> <oxm:jaxb2-marshaller id="marshaller"> <oxm:class-to-be-bound name="org.example.policy.dto.AccountSummary"/> <oxm:class-to-be-bound name="org.example.policy.dto.InsuredName"/> <oxm:class-to-be-bound name="org.example.policy.dto.Producer"/> <oxm:class-to-be-bound name="org.example.policy.dto.PropertyLocCoverage"/> <oxm:class-to-be-bound name="org.example.policy.dto.PropertyLocCoverages"/> </oxm:jaxb2-marshaller>

  • BroadcastReceiver not reading stored value from SharedPreferences

    - by bobby123
    In my app I have a broadcast receiver that turns on GPS upon receiving a set string of text. In the onLocationChanged method, I want to pass the GPS data and a value from my shared preferences to a thread in a string. I have the thread writing to log and can see all the GPS values in the string but the last value from my shared preferences is just showing up as 'prefPhoneNum' which I initialised the string to at the beginning of the receiver class. I have the same code to read the prefPhoneNum from shared preferences in the main class and it works there, can anyone see what I might be doing wrong? public class SmsReceiver extends BroadcastReceiver implements LocationListener { LocationManager lm; LocationListener loc; public SharedPreferences sharedpreferences; public static final String US = "usersettings"; public String prefPhoneNum = "prefPhoneNum"; @Override public void onReceive(Context context, Intent intent) { sharedpreferences = context.getSharedPreferences(US, Context.MODE_PRIVATE); prefPhoneNum = sharedpreferences.getString("prefPhoneNum" , ""); lm = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE); loc = new SmsReceiver(); //---get the SMS message passed in--- Bundle bundle = intent.getExtras(); SmsMessage[] msgs = null; String str = ""; if (bundle != null) { //---retrieve the SMS message received--- Object[] pdus = (Object[]) bundle.get("pdus"); msgs = new SmsMessage[pdus.length]; for (int i=0; i<msgs.length; i++) { msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]); str += msgs[i].getMessageBody().toString() + "\n"; } Toast.makeText(context, str, Toast.LENGTH_SHORT).show(); //Display SMS if ((msgs[0].getMessageBody().toString().equals("Enable")) || (msgs[0].getMessageBody().toString().equals("enable"))) { enableGPS(); } else { /* Do Nothing*/ } } } public void enableGPS() { //new CountDownTimer(10000, 1000) { //10 seconds new CountDownTimer(300000, 1000) { //300 secs = 5 mins public void onTick(long millisUntilFinished) { lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, loc); } public void onFinish() { lm.removeUpdates(loc); } }.start(); } @Override public void onLocationChanged(Location location) { String s = ""; s += location.getLatitude() + "\n"; s += location.getLongitude() + "\n"; s += location.getAltitude() + "\n"; s += location.getAccuracy() + "\n" + prefPhoneNum; Thread cThread = new Thread(new SocketsClient(s)); cThread.start(); } @Override public void onProviderDisabled(String provider) { } @Override public void onProviderEnabled(String provider) { } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } } Here is the logcat for when the application shuts - D/LocationManager( 3912): requestLocationUpdates: provider = gps, listener = accel.working.TrackGPS@4628bce0 D/GpsLocationProvider( 96): setMinTime 0 D/GpsLocationProvider( 96): startNavigating D/GpsLocationProvider( 96): TTFF: 3227 D/AndroidRuntime( 3912): Shutting down VM W/dalvikvm( 3912): threadid=1: thread exiting with uncaught exception (group=0x400259f8) E/AndroidRuntime( 3912): FATAL EXCEPTION: main E/AndroidRuntime( 3912): java.lang.NullPointerException E/AndroidRuntime( 3912): at android.content.ContextWrapper.getSharedPreferences(ContextWrapper.java:146) E/AndroidRuntime( 3912): at accel.working.TrackGPS.onLocationChanged(TrackGPS.java:63) E/AndroidRuntime( 3912): at android.location.LocationManager$ListenerTransport._handleMessage(LocationManager.java:191) E/AndroidRuntime( 3912): at android.location.LocationManager$ListenerTransport.access$000(LocationManager.java:124) E/AndroidRuntime( 3912): at android.location.LocationManager$ListenerTransport$1.handleMessage(LocationManager.java:140) E/AndroidRuntime( 3912): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 3912): at android.os.Looper.loop(Looper.java:144) E/AndroidRuntime( 3912): at android.app.ActivityThread.main(ActivityThread.java:4937) E/AndroidRuntime( 3912): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 3912): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 3912): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) E/AndroidRuntime( 3912): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) E/AndroidRuntime( 3912): at dalvik.system.NativeStart.main(Native Method)

  • Problem using form builder & DOM manipulation in Rails with multiple levels of nested partials

    - by Chris Hart
    I'm having a problem using nested partials with dynamic form builder code (from the "complex form example" code on github) in Rails. I have my top level view "new" (where I attempt to generate the template): <% form_for (@transaction_group) do |txngroup_form| %> <%= txngroup_form.error_messages %> <% content_for :jstemplates do -%> <%= "var transaction='#{generate_template(txngroup_form, :transactions)}'" %> <% end -%> <%= render :partial => 'transaction_group', :locals => { :f => txngroup_form, :txn_group => @transaction_group }%> <% end -%> This renders the transaction_group partial: <div class="content"> <% logger.debug "in partial, class name = " + txn_group.class.name %> <% f.fields_for txn_group.transactions do |txn_form| %> <table id="transactions" class="form"> <tr class="header"><td>Price</td><td>Quantity</td></tr> <%= render :partial => 'transaction', :locals => { :tf => txn_form } %> </table> <% end %> <div>&nbsp;</div><div id="container"> <%= link_to 'Add a transaction', '#transaction', :class => "add_nested_item", :rel => "transactions" %> </div> <div>&nbsp;</div> ... which in turn renders the transaction partial: <tr><td><%= tf.text_field :price, :size => 5 %></td> <td><%= tf.text_field :quantity, :size => 2 %></td></tr> The generate_template code looks like this: def generate_html(form_builder, method, options = {}) options[:object] ||= form_builder.object.class.reflect_on_association(method).klass.new options[:partial] ||= method.to_s.singularize options[:form_builder_local] ||= :f form_builder.fields_for(method, options[:object], :child_index => 'NEW_RECORD') do |f| render(:partial => options[:partial], :locals => { options[:form_builder_local] => f }) end end def generate_template(form_builder, method, options = {}) escape_javascript generate_html(form_builder, method, options) end (Obviously my code is not the most elegant - I was trying to get this nested partial thing worked out first.) My problem is that I get an undefined variable exception from the transaction partial when loading the view: /Users/chris/dev/ss/app/views/transaction_groups/_transaction.html.erb:2:in _run_erb_app47views47transaction_groups47_transaction46html46erb_locals_f_object_transaction' /Users/chris/dev/ss/app/helpers/customers_helper.rb:29:in generate_html' /Users/chris/dev/ss/app/helpers/customers_helper.rb:28:in generate_html' /Users/chris/dev/ss/app/helpers/customers_helper.rb:34:in generate_template' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:4:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:3:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:1:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/controllers/transaction_groups_controller.rb:17:in new' I'm pretty sure this is because the do loop for form_for hasn't executed yet (?)... I'm not sure that my approach to this problem is the best, but I haven't been able to find a better solution for dynamically adding form partials to the DOM. Basically I need a way to add records to a has_many model dynamically on a nested form. Any recommendations on a way to fix this particular problem or (even better!) a cleaner solution are appreciated. Thanks in advance. Chris

  • Java: how to do fast copy of a BufferedImage's pixels? (include unit test)

    - by WizardOfOdds
    I want to do a copy (of a rectangle area) of the ARGB values from a source BufferedImage into a destination BufferedImage. No compositing should be done: if I copy a pixel with an ARGB value of 0x8000BE50 (alpha value at 128), then the destination pixel must be exactly 0x8000BE50, totally overriding the destination pixel. I've got a very precise question and I made a unit test to show what I need. The unit test is fully functional and self-contained and is passing fine and is doing precisely what I want. However, I want a faster and more memory efficient method to replace copySrcIntoDstAt(...). That's the whole point of my question: I'm not after how to "fill" the image in a faster way (what I did is just an example to have a unit test). All I want is to know what would be a fast and memory efficient way to do it (ie fast and not creating needless objects). The proof-of-concept implementation I've made is obviously very memory efficient, but it is slow (doing one getRGB and one setRGB for every pixel). Schematically, I've got this: (where A indicates corresponding pixels from the destination image before the copy) AAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAA And I want to have this: AAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAABBBBAAA AAAAAAAAAAAAABBBBAAA AAAAAAAAAAAAAAAAAAAA where 'B' represents the pixels from the src image. I'm looking for an exact replacement of the method, not for an API link/quote. import org.junit.Test; import java.awt.image.BufferedImage; import static org.junit.Assert.*; public class TestCopy { private static final int COL1 = 0x8000BE50; // alpha at 128 private static final int COL2 = 0x1732FE87; // alpha at 23 @Test public void testPixelsCopy() { final BufferedImage src = new BufferedImage( 5, 5, BufferedImage.TYPE_INT_ARGB ); final BufferedImage dst = new BufferedImage( 20, 20, BufferedImage.TYPE_INT_ARGB ); convenienceFill( src, COL1 ); convenienceFill( dst, COL2 ); copySrcIntoDstAt( src, dst, 3, 4 ); for (int x = 0; x < dst.getWidth(); x++) { for (int y = 0; y < dst.getHeight(); y++) { if ( x >= 3 && x <= 7 && y >= 4 && y <= 8 ) { assertEquals( COL1, dst.getRGB(x,y) ); } else { assertEquals( COL2, dst.getRGB(x,y) ); } } } } // clipping is unnecessary private static void copySrcIntoDstAt( final BufferedImage src, final BufferedImage dst, final int dx, final int dy ) { // TODO: replace this by a much more efficient method for (int x = 0; x < src.getWidth(); x++) { for (int y = 0; y < src.getHeight(); y++) { dst.setRGB( dx + x, dy + y, src.getRGB(x,y) ); } } } // This method is just a convenience method, there's // no point in optimizing this method, this is not what // this question is about private static void convenienceFill( final BufferedImage bi, final int color ) { for (int x = 0; x < bi.getWidth(); x++) { for (int y = 0; y < bi.getHeight(); y++) { bi.setRGB( x, y, color ); } } } }

  • How to represent a Board Panel in Java for a game ? [+code]

    - by FILIaS
    I wanna fix a 2D board for a game. I've already fixed other panels for the Gui and everything goes well. But the panel for the board cant be printed on the window. I'm a bit confused about it as i think i've followed the same ideas as for the others panels i need. Here's what i've done: EDIT:*EDIT* what i'm trying to do is fix a board panel for the game according to the dimensions of the it,hold every square in an array in order to use it after wherever it;s needed. I draw each little square of it with the method draw and put it back to the panel. So, each square on the board is a panel. This is the idea. But as u can see. There are troubles/errors on it. EDIT: code updated. just found a part of the problem. i thought first that i had set background to squared, but i didnt. with this one it appears on the panel a wide black "column". Unfortunately,still none squares. :( One More EDIT: Also,i realized that draw method is never called. when i put the draw method in the following method i can see the squares but they remain small. I redefine them with setSize but still no change. /** *Method used to construct the square in the area of the *gui's grid. In this stage a GUISquare array is being constructed, * used in the whole game as *a mean of changing a square graphical state. *@param squares is the squares array from whom the gui grid will be *constructed. *@see getSquare about the correspondance beetween a squareModel and * a GUISquare. */ private void initBoardPanel(SquareModel[][] squares){ BoardPanel.setLayout(new GridLayout(height ,width )); //set layout SquareRenderer[][] Squares; JPanel[][] grid; Squares=new GUISquare[height][width()]; grid=new JPanel[height()][width()]; for (int i=0; i<height(); i++){ for (int j=0; j<width() ; j++){ grid[i][j] = new JPanel( ); SquareRenderer kout=new SquareRenderer(i,j); koutaki.setSquare(myGame.getSquares()[i][j]); if (myGame.getSquares()[i][j] instanceof SimpleSquareModel){ kout.draw(i,j,"");} else { kout.draw(i,j); } kout.setVisible(true); kout.setBackground(Color.BLACK); kout.setSize(50,50); Squares[i][j]= kout; grid[i][j].setSize(50,50); grid[i][j].setVisible(true); grid[i][j].setBackground(Color.BLACK); BoardPanel.add(kout); BoardPanel.setVisible(true); BoardPanel.setBackground(Color.WHITE); } } this.add(BoardPanel,BorderLayout.WEST); // this.pack(); //sets appropriate size for frame this.setVisible(true); //makes frame visible } IMPLEMENTED BY SQUARERENDERER: /** * Transformer for Snake/Ladder * <br>This method is used to display a square on the screen. */ public void draw(int i,int j) { JPanel panel = new JPanel(); panel.setLayout(new BorderLayout()); JLabel label1 = new JLabel("Move To"+myGame.getSquares()[i][j].getGoTo()); JLabel label2 = new JLabel(""+myGame.getSquares()[i][j].getSquare()); JSeparator CellSeparator = new JSeparator(orientation); panel.add(CellSeparator); panel.setForeground(Color.ORANGE); panel.add(label2, BorderLayout.NORTH); panel.add(label1, BorderLayout.CENTER); }

  • How to Force an Exception from a Task to be Observed in a Continuation Task?

    - by Richard
    I have a task to perform an HttpWebRequest using Task<WebResponse>.Factory.FromAsync(req.BeginGetRespone, req.EndGetResponse) which can obviously fail with a WebException. To the caller I want to return a Task<HttpResult> where HttpResult is a helper type to encapsulate the response (or not). In this case a 4xx or 5xx response is not an exception. Therefore I've attached two continuations to the request task. One with TaskContinuationOptions OnlyOnRanToCompletion and the other with OnlyOnOnFaulted. And then wrapped the whole thing in a Task<HttpResult> to pick up the one result whichever continuation completes. Each of the three child tasks (request plus two continuations) is created with the AttachedToParent option. But when the caller waits on the returned outer task, an AggregateException is thrown is the request failed. I want to, in the on faulted continuation, observe the WebException so the client code can just look at the result. Adding a Wait in the on fault continuation throws, but a try-catch around this doesn't help. Nor does looking at the Exception property (as section "Observing Exceptions By Using the Task.Exception Property" hints here). I could install a UnobservedTaskException event handler to filter, but as the event offers no direct link to the faulted task this will likely interact outside this part of the application and is a case of a sledgehammer to crack a nut. Given an instance of a faulted Task<T> is there any means of flagging it as "fault handled"? Simplified code: public static Task<HttpResult> Start(Uri url) { var webReq = BuildHttpWebRequest(url); var result = new HttpResult(); var taskOuter = Task<HttpResult>.Factory.StartNew(() => { var tRequest = Task<WebResponse>.Factory.FromAsync( webReq.BeginGetResponse, webReq.EndGetResponse, null, TaskCreationOptions.AttachedToParent); var tError = tRequest.ContinueWith<HttpResult>( t => HandleWebRequestError(t, result), TaskContinuationOptions.AttachedToParent |TaskContinuationOptions.OnlyOnFaulted); var tSuccess = tRequest.ContinueWith<HttpResult>( t => HandleWebRequestSuccess(t, result), TaskContinuationOptions.AttachedToParent |TaskContinuationOptions.OnlyOnRanToCompletion); return result; }); return taskOuter; } with: private static HttpDownloaderResult HandleWebRequestError( Task<WebResponse> respTask, HttpResult result) { Debug.Assert(respTask.Status == TaskStatus.Faulted); Debug.Assert(respTask.Exception.InnerException is WebException); // Try and observe the fault: Doesn't help. try { respTask.Wait(); } catch (AggregateException e) { Log("HandleWebRequestError: waiting on antecedent task threw inner: " + e.InnerException.Message); } // ... populate result with details of the failure for the client ... return result; } (HandleWebRequestSuccess will eventually spin off further tasks to get the content of the response...) The client should be able to wait on the task and then look at its result, without it throwing due to a fault that is expected and already handled.

  • Populating a GridView with ImageViews dynamically/programmatically using a ImageAdapter

    - by Julian Vogels
    Hi folks, this is my first question at stackoverflow, but it's a little tricky already... I try to develop an Android App which allows the user to fetch data from flickr and show it in a gridview (with some nice 3D-Animation). After some adventures i got it almost running, but now I'm stuck. Here's the problem: I got a UI Thread "LoadPhotosTask" which gets the pictures from flickr, just like the open source application photostream. In the method onProgressUpdate(LoadedPhoto... value) of that subclass I call addPhoto(). Until now everythings fine - I got some nice Bitmap and Flickr.photo data with all the information I need. @Override public void onProgressUpdate(LoadedPhoto... value) { addPhoto(value); } On the other hand I have got a GridView. Now I want to fill it with the Photos. It has got an adapter called ImageAdapter (which extends BaseAdapter, see this tutorial). If I use an array inside the ImageAdapter class I can populate the GridView with some sample images. But if I want to populate it at runtime, I don't know what to do. How do I have to set up the getView method in the ImageAdapter? I was trying to fill the array inside the ImageAdapter class with my values in addPhoto, but it doesn't display anything. So first of all I was setting up the array with the amount of Photos i wanted to display in the grid like that (code is inside the ImageAdapter class): // class variable private ImageView[] mThumbIds; [...] public void setupArray(int count) { this.mThumbIds = new ImageView[count]; } Then I call this method with the lenght of my photolist: final Flickr.PhotoList list = params[0]; final int count = list.getCount(); int helper = 0; imagead.setupArray(count); Afterwards I call the getView method manually inside the addPhoto method: private void addPhoto(LoadedPhoto... value) { ImageView image = (ImageView) mInflater.inflate( R.layout.grid_item_photo, null); image.setImageBitmap(value[0].mBitmap); image.setTag(value[0].mPhoto); imagead.setmThumbIds(image, value[0].mPosition); imagead.getView(value[0].mPosition, null, mpicturesGrid); } That is the getView method inside ImageAdapter: public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { // if it's not recycled, initialize some // attributes imageView = new ImageView(mContext); imageView.setLayoutParams(new GridView.LayoutParams(EDGE_LENGTH, EDGE_LENGTH)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(0, 0, 0, 0); imageView.setVisibility(View.VISIBLE); } else { imageView = (ImageView) convertView; } imageView.setImageDrawable(mThumbIds[position].getDrawable()); imageView.setTag(mThumbIds[position].getTag()); return imageView; } Ok, finally I apologize for my poor english and I hope you can give me some help with the information I provided. Greetings, Julian

  • clojure.algo.monad strange m-plus behaviour with parser-m - why is second m-plus evaluated?

    - by Mark Fisher
    I'm getting unexpected behaviour in some monads I'm writing. I've created a parser-m monad with (def parser-m (state-t maybe-m)) which is pretty much the example given everywhere (here, here and here) I'm using m-plus to act a kind of fall-through query mechanism, in my case, it first reads values from a cache (database), if that returns nil, the next method is to read from "live" (a REST call). However, the second value in the m-plus list is always called, even though its value is disgarded (if the cache hit was good) and the final return is that of the first monadic function. Here's a cutdown version of the issue i'm seeing, and some solutions I found, but I don't know why. My questions are: Is this expected behaviour or a bug in m-plus? i.e. will the 2nd method in a m-plus list always be evaluated if the first item returns a value? Minor in comparison to the above, but if i remove the call _ (fetch-state) from checker, when i evaluate that method, it prints out the messages for the functions the m-plus is calling (when i don't think it should). Is this also a bug? Here's a cut-down version of the code in question highlighting the problem. It simply checks key/value pairs passed in are same as the initial state values, and updates the state to mark what it actually ran. (ns monods.monad-test (:require [clojure.algo.monads :refer :all])) (def parser-m (state-t maybe-m)) (defn check-k-v [k v] (println "calling with k,v:" k v) (domonad parser-m [kv (fetch-val k) _ (do (println "k v kv (= kv v)" k v kv (= kv v)) (m-result 0)) :when (= kv v) _ (do (println "passed") (m-result 0)) _ (update-val :ran #(conj % (str "[" k " = " v "]"))) ] [k v])) (defn filler [] (println "filler called") (domonad parser-m [_ (fetch-state) _ (do (println "filling") (m-result 0)) :when nil] nil)) (def checker (domonad parser-m [_ (fetch-state) result (m-plus ;; (filler) ;; intitially commented out deliberately (check-k-v :a 1) (check-k-v :b 2) (check-k-v :c 3))] result)) (checker {:a 1 :b 2 :c 3 :ran []}) When I run this as is, the output is: > (checker {:a 1 :b 2 :c 3 :ran []}) calling with k,v: :a 1 calling with k,v: :b 2 calling with k,v: :c 3 k v kv (= kv v) :a 1 1 true passed k v kv (= kv v) :b 2 2 true passed [[:a 1] {:a 1, :b 2, :c 3, :ran ["[:a = 1]"]}] I don't expect the line k v kv (= kv v) :b 2 2 true to show at all. The first function to m-plus (as seen in the final output) is what is returned from it. Now, I've found if I pass a filler into m-plus that does nothing (i.e. uncomment the (filler) line) then the output is correct, the :b value isn't evaluated. If I don't have the filler method, and make the first method test fail (i.e. change it to (check-k-v :a 2) then again everything is good, I don't get a call to check :c, only a and b are tested. From my understanding of what the state-t maybe-m transformation is giving me, then the m-plus function should look like: (defn m-plus [left right] (fn [state] (if-let [result (left state)] result (right state)))) which would mean that right isn't called unless left returns nil/false. I'd be interested to know if my understanding is correct or not, and why I have to put the filler method in to stop the extra evaluation (whose effects I don't want to happen). Apologies for the long winded post!

  • xmlpullparser(), whats wrong with my code?

    - by Avinazz
    I am expecting output to be an array list filled with all items as "thought" but instead, every time i add a value into arraylist, the previous value in list also gets update with new, hence resulting in duplicates. This behaviour goes on till end. Even though i have achieved the result by changing the approach, failure of my previous approach still bothers me. Any help or pointer will be really appreciated. Below is xml snippet: <Thoughts> <country> <name>India</name> <item> <itemId>1</itemId> <itemDetailImage>detail.png</itemDetailImage> <itemImage>image1.png</itemImage> <itemDesc>Item Description 1</itemDesc> <itemTitle>Item Title 1</itemTitle> </item> <item> <itemId>2</itemId> <itemDetailImage>detail2.png</itemDetailImage> <itemImage>image2.png</itemImage> <itemDesc>Item Description 2</itemDesc> <itemTitle>Item Title 2</itemTitle> </item> <item> <itemId>3</itemId> <itemDetailImage>detail3.png</itemDetailImage> <itemImage>image3.png</itemImage> <itemDesc>Item Description 3</itemDesc> <itemTitle>Item Title 3</itemTitle> </item> Below is a method for my trial and error: private void printAll() throws XmlPullParserException, IOException{ XmlPullParserFactory factory = XmlPullParserFactory.newInstance(); factory.setNamespaceAware(false); XmlPullParser parser = factory.newPullParser(); URL url = new URL("http://192.168.1.3/DefaultXML.xml"); URLConnection ucon = url.openConnection(); InputStream is = ucon.getInputStream(); parser.setInput(is, null); int eventType = parser.getEventType(); String name; while(eventType != parser.END_DOCUMENT){ if(eventType == parser.START_DOCUMENT){ Log.i(TAG,"Start document"); }else if (eventType == parser.START_TAG ) { name = parser.getName(); if(name.equalsIgnoreCase(NAME)){ this.cName = new Country(); this.cName.setName(parser.nextText()); }else if(name.equalsIgnoreCase(ITEM_DESC)){ this.thought.setItemDesc(parser.nextText()); }else if (name.equalsIgnoreCase(ITEM_ID)) { this.thought.setItemID(parser.nextText()); }else if (name.equalsIgnoreCase(ITEM_DETAIL_IMAGE)) { this.thought.setItemDetailImage(parser.nextText()); }else if (name.equalsIgnoreCase(ITEM_IMAGE)) { this.thought.setItemImage(parser.nextText()); }else if (name.equalsIgnoreCase(ITEM_TITLE)) { this.thought.setItemTitle(parser.nextText()); } }else if (eventType == parser.END_TAG) { name = parser.getName(); if(name.equalsIgnoreCase(ITEM)) { this.cName.setThought(this.thought); ctry.add(cName); this.thought = new Thought(); } } eventType = parser.next(); } //Log.i(TAG,"---" + ctry.toString()); }

When there are errors with the form, and it is returned to the browser, the select options are not re-populated with the selections the user made even though the returned values for those fields match the values of options in the selects. Also, when the form is returned, these fields are not marked as having errors even though their values are blank. Here's the frequency and duration fields in Rails <%= frequency_select c, :frequency %> <%= duration_select c, :duration %> The method for frequency_select is def frequency_select(f, method) options = [["day", 1.day], ["other day", 2.days], ["week", 1.week]] f.select method, options, :include_blank => true end And the method for duration_select is def duration_select(f, method, unit="day" ) values, units = *case unit when "day" : [[[5, 5], [15, 15], [30, 29]], "days"] when "other day" : [[[15, 15], [30, 29], [45,45]], "days"] when "week" : [[[4, 29], [6, 43], [8, 57]], "weeks"] end f.select method, values.map {|(label, i)| ["#{label} #{units}", i.days]}, :include_blank => true end If you enter a value into one or both of these fields and submit the form without completing part of it (any part of it), the form is returned to the user (as would be expected), but the duration and frequency fields are not re-populated with the user's selection. If I add this bit of code to the form <p><%= @challenge.attributes.inspect %></p> I see that this for duration and frequency when the form is returned to the browser: "duration"=>3888000, "frequency"=>172800 These values match values on the options in the select fields. Is there anything special in Rails that needs to be done so that the select fields are re-populated with the user's selections? Any thoughts on what the problem could be or what I should try next? Help is greatly appreciated! -Rick PS If you look at some of the other questions, you'll notice I've asked about this in the past. At one point, I thought the form was returning values for frequency and duration in days rather than seconds, but that's not the case. PPS Here's one other bit of information that might matter, but my tests indicate that it probably does not. (Though, I'm a bit of a newbie to this, so don't take my word for it.) These two fields are chained together using the cascade jquery plugin. The javascript is included on the page (not in a separate file) and some of the js is being created by Rails. First, here are the scripts as they appear in the browser. The first is the script to generate the options for the duration select and the second is the script required by the Cascade plugin to trigger the field chaining. <script type="text/javascript"> var list1 = [ {'When':'86400','Value':' ','Text':' '}, {'When':'172800','Value':' ','Text':' '}, {'When':'604800','Value':' ','Text':' '}, {'When':'86400','Value':'432000','Text':'5 days'}, {'When':'86400','Value':'1296000','Text':'15 days'}, {'When':'86400','Value':'2505600','Text':'30 days'}, {'When':'172800','Value':'1296000','Text':'15 days'}, {'When':'172800','Value':'2505600','Text':'30 days'}, {'When':'172800','Value':'3888000','Text':'45 days'}, {'When':'604800','Value':'2505600','Text':'4 weeks'}, {'When':'604800','Value':'3715200','Text':'6 weeks'}, {'When':'604800','Value':'4924800','Text':'8 weeks'} ]; function commonTemplate(item) { return "<option value='" + item.Value + "'>" + item.Text + "</option>"; }; function commonMatch(selectedValue) { return this.When == selectedValue; }; </script> <script type="text/javascript"> jQuery(document).ready(function(){ jQuery("#challenge_duration, #user_challenge_duration").cascade("#challenge_frequency, #user_challenge_frequency",{ list: list1, template: commonTemplate, match: commonMatch }) }); </script> And here's a bit of the the first script as it is in the erb file -- you see that some of the script is being generated by Rails <%= [ [1.day, [[5, 5], [15,15], [30, 29]], "days"], [2.days, [[15, 15], [30, 29], [45, 45]], "days"], [1.week, [[4, 29], [6, 43], [8, 57]], "weeks"]].map do |(frequency, durations, unit)| durations.map do |(label, value)| "{'When':'#{frequency}','Value':'#{value.days}','Text':'#{label} #{unit}'}" end end.join(",\n") -%> Now, the reason I don't think that it matters whether the duration is being generated with JS is the problem still exists if I remove all the JS the problem also affects the frequency field, whose options are not being generated by the JS

  • How to get the value of an item from database and set it as the spinner value

    - by kulPrins
    I have a database and the database populates a listview. when i long press a list item from the listview i get a context menu where i have the option to edit. When the edit option is clicked i open an activity and get all the values of the respective fields from the database. Now, here I want to get a value from the database and show it in the spinner. the spinner already has these values and is getting populated from the database... I have tried the following, but i get an error saying I can't cast a SimpleCursorAdapter to an ArrayAdapter.. String osub = cursor.getString(Database.INDEX_SUBJECT); Cursor cs = mDBS.querySub(osub); String subs = cs.getString(DatabaseSub.INDEX_SSUBJECT); if(cs!=null){ ArrayAdapter<String> myAdap = (ArrayAdapter<String>) subSpinner.getAdapter(); //cast to an ArrayAdapter int spinnerPosition = myAdap.getPosition(subs); //set the default according to value subSpinner.setSelection(spinnerPosition); Please tell me how to do this.. Thank you.. I am relatively new so please let me know if I am overlooking something. Thanks..

  • Help with optimizing C# function via C and/or Assembly

    - by MusiGenesis
    I have this C# method which I'm trying to optimize: // assume arrays are same dimensions private void DoSomething(int[] bigArray1, int[] bigArray2) { int data1; byte A1; byte B1; byte C1; byte D1; int data2; byte A2; byte B2; byte C2; byte D2; for (int i = 0; i < bigArray1.Length; i++) { data1 = bigArray1[i]; data2 = bigArray2[i]; A1 = (byte)(data1 >> 0); B1 = (byte)(data1 >> 8); C1 = (byte)(data1 >> 16); D1 = (byte)(data1 >> 24); A2 = (byte)(data2 >> 0); B2 = (byte)(data2 >> 8); C2 = (byte)(data2 >> 16); D2 = (byte)(data2 >> 24); A1 = A1 > A2 ? A1 : A2; B1 = B1 > B2 ? B1 : B2; C1 = C1 > C2 ? C1 : C2; D1 = D1 > D2 ? D1 : D2; bigArray1[i] = (A1 << 0) | (B1 << 8) | (C1 << 16) | (D1 << 24); } } The function basically compares two int arrays. For each pair of matching elements, the method compares each individual byte value and takes the larger of the two. The element in the first array is then assigned a new int value constructed from the 4 largest byte values (irrespective of source). I think I have optimized this method as much as possible in C# (probably I haven't, of course - suggestions on that score are welcome as well). My question is, is it worth it for me to move this method to an unmanaged C DLL? Would the resulting method execute faster (and how much faster), taking into account the overhead of marshalling my managed int arrays so they can be passed to the method? If doing this would get me, say, a 10% speed improvement, then it would not be worth my time for sure. If it was 2 or 3 times faster, then I would probably have to do it. Note: please, no "premature optimization" comments, thanks in advance. This is simply "optimization".

  • Associating an Object with other Objects and Properties of those Objects

    - by alzoid
    I am looking for some help with designing some functionality in my application. I already have something similar designed but this problem is a little different. Background: In my application we have different Modules. Data in each module can be associated to other modules. Each Module is represented by an Object in our application. Module 1 can be associated with Module 2 and Module 3. Currently I use a factory to provide the proper DAO for getting and saving this data. It looks something like this: class Module1Factory { public static Module1BridgeDAO createModule1BridgeDAO(int moduleid) { switch (moduleId) { case Module.Module2Id: return new Module1_Module2DAO(); case Module.Module3Id: return new Module1_Module3DAO(); default: return null; } } } Module1_Module2 and Module1_Module3 implement the same BridgeModule interface. In the database I have a Table for every module (Module1, Module2, Module3). I also have a bridge table for each module (they are many to many) Module1_Module2, Module1_Module3 etc. The DAO basically handles all code needed to manage the association and retrieve its own instance data for the calling module. Now when we add new modules that associate with Module1 we simply implement the ModuleBridge interface and provide the common functionality. New Development We are adding a new module that will have the ability to be associated with other Modules as well as specific properties of that module. The module is basically providing the user the ability to add their custom forms to our other modules. That way they can collect additional information along with what we provide. I want to start associating my Form module with other modules and their properties. Ie if Module1 has a property Category, I want to associate an instance From data with that property. There are many Forms. If a users creates an instance of Module2, they may always want to also have certain form(s) attached to that Module2 instance. If they create an instance of Module2 and select Category 1, then I may want additional Form(s) created. I prototyped something like this: Form FormLayout (contains the labels and gui controls) FormModule (associates a form with all instances of a module) Form Instance (create an instance of a form to be filled out) As I thought about it I was thinking about making a new FormModule table/class/dao for each Module and Property that I add. So I might have: FormModule1 FormModule1Property1 FormModule1Property2 FormModule1Property3 FormModule1Property4 FormModule2 FormModule3 FormModule3Property1 Then as I did previously, I would use a factory to get the proper DAO for dealing with all of these. I would hand it an array of ids representing different modules and properties and it would return all of the DAOs that I need to call getForms(). Which in turn would return all of the forms for that particular bridge. Some points This will be for a new module so I dont need to expand on the factory code I provided. I just wanted to show an example of what I have done in the past. The new module can be associated with: Other Modules (ie globally for any instance of that module data), Other module properties (ie only if the Module instance has a certian value in one of its properties) I want to make it easy for developers to add associations with other modules and properties easily Can any one suggest any design patterns or strategy's for achieving this? If anything is unclear please let me know. Thank you, Al

    I am making a very simple app with an RSS reader. The reader works great, but it's only giving me the title, and i want the description too. I'am very new to android, and I have tried a lot of things, but I can't get it to work.

  • How to call virtual function of an object in C++

    - by SoonDead
    I'm struggling with calling a virtual function in C++. I'm not experienced in C++, I mainly use C# and Java so I might have some delusions, but bear with me. I have to write a program where I have to avoid dynamic memory allocation if possible. I have made a class called List: template <class T> class List { public: T items[maxListLength]; int length; List() { length = 0; } T get(int i) const { if (i >= 0 && i < length) { return items[i]; } else { throw "Out of range!"; } }; // set the value of an already existing element void set(int i, T p) { if (i >= 0 && i < length) { items[i] = p; } else { throw "Out of range!"; } } // returns the index of the element int add(T p) { if (length >= maxListLength) { throw "Too many points!"; } items[length] = p; return length++; } // removes and returns the last element; T pop() { if (length > 0) { return items[--length]; } else { throw "There is no element to remove!"; } } }; It just makes an array of the given type, and manages the length of it. There is no need for dynamic memory allocation, I can just write: List<Object> objects; MyObject obj; objects.add(obj); MyObject inherits form Object. Object has a virtual function which is supposed to be overridden in MyObject: struct Object { virtual float method(const Input& input) { return 0.0f; } }; struct MyObject: public Object { virtual float method(const Input& input) { return 1.0f; } }; I get the elements as: objects.get(0).method(asdf); The problem is that even though the first element is a MyObject, the Object's method function is called. I'm guessing there is something wrong with storing the object in an array of Objects without dynamically allocating memory for the MyObject, but I'm not sure. Is there a way to call MyObject's method function? How? It's supposed to be a heterogeneous collection btw, so that's why the inheritance is there in the first place. If there is no way to call the MyObject's method function, then how should I make my list in the first place?
