  • Why do I get empty request from the Jakarta Commons HttpClient?

    - by polyurethan
    I have a problem with the Jakarta Commons HttpClient. Before my self-written HttpServer gets the real request there is one request which is completely empty. That's the first problem. The second problem is, sometimes the request data ends after the third or fourth line of the http request: POST / HTTP/1.1 User-Agent: Jakarta Commons-HttpClient/3.1 Host: 127.0.0.1:4232 For debugging I am using the Axis TCPMonitor. There every things is fine but the empty request. How I process the stream: StringBuffer requestBuffer = new StringBuffer(); InputStreamReader is = new InputStreamReader(socket.getInputStream(), "UTF-8"); int byteIn = -1; do { byteIn = is.read(); if (byteIn > 0) { requestBuffer.append((char) byteIn); } } while (byteIn != -1 && is.ready()); String requestData = requestBuffer.toString(); How I send the request: client.getParams().setSoTimeout(30000); method = new PostMethod(url.getPath()); method.getParams().setContentCharset("utf-8"); method.setRequestHeader("Content-Type", "application/xml; charset=utf-8"); method.addRequestHeader("Connection", "close"); method.setFollowRedirects(false); byte[] requestXml = getRequestXml(); method.setRequestEntity(new InputStreamRequestEntity(new ByteArrayInputStream(requestXml))); client.executeMethod(method); int statusCode = method.getStatusCode(); Have anyone of you an idea how to solve these problems?

  • Returning values from Swing using invokeAndWait

    - by Joonas Pulakka
    I've been using the following approach to create components and return values from Swing to/from outside the EDT. For instance, the following method could be an extension to JFrame, to create a JPanel and add it to the parent JFrame: public JPanel threadSafeAddPanel() { final JPanel[] jPanel = new JPanel[1]; try { EventQueue.invokeAndWait(new Runnable() { public void run() { jPanel[0] = new JPanel(); add(jPanel[0]); } }); } catch (InterruptedException ex) { } catch (InvocationTargetException ex) { } return jPanel[0]; } The local 1-length array is used to transfer the "result" from inside the Runnable, which is invoked in the EDT. Well, it looks "a bit" hacky, and so my questions: Does this make sense? Is anybody else doing something like this? Is the 1-length array a good way of transferring the result? Is there an easier way to do this?

  • Using Apache Velocity with StringBuilders/CharSequences

    - by mindas
    We are using Apache Velocity for dynamic templates. At the moment Velocity has following methods for evaluation/replacing: public static boolean evaluate(Context context, Writer writer, String logTag, Reader reader) public static boolean evaluate(Context context, Writer out, String logTag, String instring) We use these methods by providing StringWriter to write evaluation results. Our incoming data is coming in StringBuilder format so we use StringBuilder.toString and feed it as instring. The problem is that our templates are fairly large (can be megabytes, tens of Ms on rare cases), replacements occur very frequently and each replacement operation triples the amount of required memory (incoming data + StringBuilder.toString() which creates a new copy + outgoing data). I was wondering if there is a way to improve this. E.g. if I could find a way to provide a Reader and Writer on top of same StringBuilder instance that only uses extra memory for in/out differences, would that be a good approach? Has anybody done anything similar and could share any source for such a class? Or maybe there any better solutions to given problem?

  • Creating a table with an initial element selected

    - by Tony
    I want to create a table which displays in each row a set of data, in addition to a radio button for possible selection. This can be achieved easily by using a simple table model class which extends the DefaultTableModel and a cell renderer and editor class which implements the TableCellRenderer and TableCellEditor interfaces respectively. What I really couldn't manage to do is to make the table to display initially one of the elements (rows) initially selected. It seems straightforward but it isn't...does anybody have a clue about it?

  • Loopj Android Async Http - onFailure not fired

    - by Ashley Staggs
    I am using the great async http library from loopj, but I have run into a small snag. If the user has no internet connection or loses their connection, the app just won't return anything. This part is expected, but it also doesn't fire the onFailure method. Also, the code I have used when there is an internet connection does work so there is no problem on the server end. Here is some code that is stripped down to the minimum. It also doesn't work (I have tested this too) String url = getString(R.string.baseurl) + "/appconnect.php"; client.getHttpClient().getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true); client.get(url, null, new JsonHttpResponseHandler() { @Override public void onSuccess(JSONArray response) { Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show(); } @Override public void onFailure(Throwable e, JSONArray errorResponse) { Toast.makeText(getApplicationContext(), "Failure", Toast.LENGTH_SHORT).show(); } }); Thanks, Ashley

  • Eclipse hangs when rebuilding after the addition of an external JAR file.

    - by celestialorb
    I'm fairly new to Eclipse so if this is something simple I apologize, however when I attempt to add an external JAR file to my build path (specifically the "rt.jar" file which contains certain tools that I require) and then rebuild my project, Eclipse will hang at the end of the Build process. It'll get to 100% then just hang there using 100% of one of my CPU cores. At first I thought it may have been due to the relatively large size of the rt.jar file, but I tried using smaller JAR files and it still hung at 100%. Any help would be greatly appreciated! If there is something wrong with using the rt.jar file does anyone know of another JAR file that contains both tools for dealing with SOAP requests as well as XML/DOM manipulation? Thanks again!

  • Put together tiles in android sdk and use as background

    - by Jon
    In a feeble attempt to learn some Android development am I stuck at graphics. My aim here is pretty simple: Take n small images and build a random image, larger than the screen with possibility to scroll around. Have an animated object move around on it I have looked at the SDK examples, Lunar Lander especially but there are a few things I utterly fail to wrap my head around. I've got a birds view plan (which in my head seems reasonably sane): How do I merge the tiles into one large image? The background is static so I figure I should do like this: Make a 2d array with refs to the tiles Make a large Drawable and draw the tiles on it At init draw this big image as the background At each onDraw redraw the background of the previous spot of the moving object, and the moving object at its new location The problem is the hands on things. I load the small images with "Bitmap img1 = BitmapFactory.decodeResource (res, R.drawable.img1)", but then what? Should I make a canvas and draw the images on it with "canvas.drawBitmap (img1, x, y, null);"? If so how to get a Drawable/Bitmap from that? I'm totally lost here, and would really appreciate some hands on help (I would of course be grateful for general hints as well, but I'm primarily trying to understand the Graphics objects). To make you, dear reader, see my level of confusion will I add my last desperate try: Drawable drawable; Canvas canvas = new Canvas (); Bitmap img1 = BitmapFactory.decodeResource (res, R.drawable.img1); // 50 x 100 px image Bitmap img2 = BitmapFactory.decodeResource (res, R.drawable.img2); // 50 x 100 px image canvas.drawBitmap (img1, 0, 0, null); canvas.drawBitmap (img2, 50, 0, null); drawable.draw (canvas); // obviously wrong as draw == null this.setBackground (drawable); Thanks in advance

  • Draw a Image on FullScreen mode Android

    - by Marcos Vasconcelos
    Hi, I already know how to get my Activity as fullscreen on Android, now I need to draw a Image in this screen. This is my XML layout. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/image01" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout> This image is dynamic generated and drawed in the ImageView. This is my code on my Activity. public void onCreate(Bundle savedInstance) { super.onCreate(savedInstance); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.main); } But when running, the Activity is FullScreen, but the ImageView is adjusted in the center. What's wrong?

  • How to inject ServletContext for JUnit tests with Spring?

    - by Juri Glass
    Hi I want to unit test a RESTful interface written with Apache CXF. I use a ServletContext to load some resources, so I have: @Context private ServletContext servletContext; If I deploy this on Glassfish, the ServletContext is injected and it works like expected. But I don't know how to inject the ServletContext in my service class, so that I can test it with a JUnit test. I use Spring 3.0, JUnit 4, CXF 2.2.3 and Maven.

  • Accessing global variable in multithreaded Tomcat server

    - by jwegan
    I have a singleton object that I construct like thus: private static volatile KeyMapper mapper = null; public static KeyMapper getMapper() { if(mapper == null) { synchronized(Utils.class) { if(mapper == null) { mapper = new LocalMemoryMapper(); } } } return mapper; } The class KeyMapper is basically a synchronized wrapper to HashMap with only two functions, one to add a mapping and one to remove a mapping. When running in Tomcat 6.24 on my 32bit Windows machine everything works fine. However when running on a 64 bit Linux machine (CentOS 5.4 with OpenJDK 1.6.0-b09) I add one mapping and print out the size of the HashMap used by KeyMapper to verify the mapping got added (i.e. verify size = 1). Then I try to retrieve the mapping with another request and I keep getting null and when I checked the size of the HashMap it was 0. I'm confident the mapping isn't accidentally being removed since I've commented out all calls to remove (and I don't use clear or any other mutators, just get and put). The requests are going through Tomcat 6.24 (configured to use 200 threads with a minimum of 4 threads) and I passed -Xnoclassgc to the jvm to ensure the class isn't inadvertently getting garbage collected (jvm is also running in -server mode). I also added a finalize method to KeyMapper to print to stderr if it ever gets garbage collected to verify that it wasn't being garbage collected. I'm at my wits end and I can't figure out why one minute the entry in HashMap is there and the next it isn't :(

  • Where about should my main class be created in a project?

    - by Dan
    The problem is where a class should be created in my code. An example is I have a UI class and a main logic class that controls other objects. Should the main logic class create the UI object, or should the UI object create the instance of the main logic class? An explanation of which method is best and why would be ideal. Thanks.

  • dynamically change bitmap in imageView, android

    - by Junfei Wang
    All, I have a problem related to imageView, android. I have array which contains of 10 bitmap objects, called bm. I have a imageView, called im. Now I wanna show the bitmaps in the array in im one by one, so I did the following: new Thread(new Runnable() { public void run() { for(int j=0;j<10;j++){ im.setImageBitmap(bm[j]); } } }).start(); But the result only shows the last bitmap in the array. Can someone tell me what to do with this issue? Millions of thanks!

  • Avoid having a huge collection of ids by calling a DAO.getAll()

    - by Michael Bavin
    Instead of returning a List<Long> of ids when calling PersonDao.getAll() we wanted not to have an entire collection of ids in memory. Seems like returning a org.springframework.jdbc.support.rowset.SqlRowSet and iterate over this rowset would not hold every object in memory. The only problem here is i cannot cast this row to my entity. Is there a better way for this?

  • Loading data in constructors and not in constructors

    - by Richeve S. Bebedor
    I just want to know the difference between loading the data inside the constructor and loading the data outside the constructor but not inside any methods example: Loading inside constructor public class Model{ Object testobject; public Model(){ testobject=new Object(); } } VS example: Loading outside constructor public class Model{ Object testobject=new Object(); public Model(){ } }

  • Allow for modular development while still running in same JVM?

    - by Marcus
    Our current app runs in a single JVM. We are now splitting up the app into separate logical services where each service runs in its own JVM. The split is being done to allow a single service to be modified and deployed without impacting the entire system. This reduces the need to QA the entire system - just need to QA the interaction with the service being changed. For inter service communication we use a combination of REST, an MQ system bus, and database views. What I don't like about this: REST means we have to marshal data to/from XML DB views couple the systems together which defeats the whole concept of separate services MQ / system bus is added complexity There is inevitably some code duplication between services You have set up n JBoss server configurations, we have to do n number of deployments, n number of set up scripts, etc, etc. Is there a better way to structure an internal application to allow modular development and deployment while allowing the app to run in a single JVM (and achieving the associated benefits)?

  • Hibernate Query for a List of Objects that matches a List of Objects' ids

    - by sal
    Given a classes Foo, Bar which have hibernate mappings to tables Foo, A, B and C public class Foo { Integer aid; Integer bid; Integer cid; ...; } public class Bar { A a; B b; C c; ...; } I build a List fooList of an arbitrary size and I would like to use hibernate to fetch List where the resulting list will look something like this: Bar[1] = [X1,Y2,ZA,...] Bar[2] = [X1,Y2,ZB,...] Bar[3] = [X1,Y2,ZC,...] Bar[4] = [X1,Y3,ZD,...] Bar[5] = [X2,Y4,ZE,...] Bar[6] = [X2,Y4,ZF,...] Bar[7] = [X2,Y5,ZG,...] Bar[8] = ... Where each Xi, Yi and Zi represents a unique object. I know I can iterate fooList and fetch each List and call barList.addAll(...) to build the result list with something like this: List<bar> barList.addAll(s.createQuery("from Bar bar where bar.aid = :aid and ... ") .setEntity("aid", foo.getAid()) .setEntity("bid", foo.getBid()) .setEntity("cid", foo.getCid()) .list(); ); Is there any easier way, ideally one that makes better use of hibernate and make a minimal number of database calls? Am I missing something? Is hibernate not the right tool for this?
