  • Number of args for stored procedure PLS-00306

    - by Peter Kaleta
    Hi I have problem with calling for my procedure. Oracle scrams PLS-00306 Error: Wrong number of types of arguments in call to procedure. With my type declaration procedure has exact the same declaration like in header below. If I run it as separate procedure it works, when i work in ODCI interface for extensible index creation, it throws PLS-00306.

  • Trouble with LINQ databind to GridView and RowDataBound

    - by Michael
    Greetings all, I am working on redesigning my personal Web site using VS 2008 and have chosen to use LINQ to create by data-access layer. Part of my site will be a little app to help manage my budget better. My first LINQ query does successfully execute and display in a GridView, but when I try to use a RowDataBound event to work with the results and refine them a bit, I get the error: The type or namespace name 'var' could not be found (are you missing a using directive or an assembly reference?) This interesting part is, if I just try to put in a var s = "s"; anywhere else in the same file, I get the same error too. If I go to other files in the web project, var s = "s"; compiles fine. Here is the LINQ Query call: public static IQueryable pubGetRecentTransactions(int param_accountid) { clsDataContext db; db = new clsDataContext(); var query = from d in db.tblMoneyTransactions join p in db.tblMoneyTransactions on d.iParentTransID equals p.iTransID into dp from p in dp.DefaultIfEmpty() where d.iAccountID == param_accountid orderby d.dtTransDate descending, d.iTransID ascending select new { d.iTransID, d.dtTransDate, sTransDesc = p != null ? p.sTransDesc : d.sTransDesc, d.sTransMemo, d.mTransAmt, d.iCheckNum, d.iParentTransID, d.iReconciled, d.bIsTransfer }; return query; } protected void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { this.prvLoadData(); } } internal void prvLoadData() { prvCtlGridTransactions.DataSource = clsMoneyTransactions.pubGetRecentTransactions(2); prvCtlGridTransactions.DataBind(); } protected void prvCtlGridTransactions_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { var datarow = e.Row.DataItem; var s = "s"; e.Row.Cells[0].Text = datarow.dtTransDate.ToShortDateString(); e.Row.Cells[1].Text = datarow.sTransDesc; e.Row.Cells[2].Text = datarow.mTransAmt.ToString("c"); e.Row.Cells[3].Text = datarow.iReconciled.ToString(); }//end if }//end RowDataBound My googling to date hasn't found a good answer, so I turn it over to this trusted community. I appreciate your time in assisting me.

  • How does a java web project architecture look like without EJB3 ?

    - by Hendrik
    A friend and I are building a fairly complex website based on java. (PHP would have been more obvious but we chose for java because the educational aspect of this project is important to us) We have already decided to use JSF (with richfaces) for the front end and JPA for the backend and so far we have decided not to use EJB3 for the business layer. The reason we've decided not to use EJB3 is because - and please correct me if I am wrong - if we use EJB3 we can only run it on a full blown java application server like jboss and if we don't use EJB3 we can still run it on a lightweight server like tomcat. We want to keep speed and cost of our future web server in mind. So far i've worked on two JEE projects and both used the full stack with web business logic factories/persistence service entities with every layer a seperate module. Now here is my question, if you dont use EJB3 in the business logic layer. What does the layer look like? Please tell what is common practice when developing java web projects without ejb3? Do you think business logic layer can be thrown out altogether and have business logic in the backing beans? If you keep the layer, do you have all business methods static? Or do you initialize each business class as needed in the backing beans in every session as needed?

  • Problems saving a photo to a file

    - by Peter vdL
    Man, I am still not able to save a picture when I send an intent asking for a photo to be taken. Here's what I am doing: Make a URI representing the pathname android.content.Context c = getApplicationContext(); String fname = c.getFilesDir().getAbsolutePath()+"/parked.jpg"; java.io.File file = new java.io.File( fname ); Uri fileUri = Uri.fromFile(file); Create the Intent (don't forget the pkg name!) and start the activity private static int TAKE_PICTURE = 22; Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE ); intent.putExtra("com.droidstogo.boom1." + MediaStore.EXTRA_OUTPUT, fileUri); startActivityForResult( intent, TAKE_PICTURE ); The camera activity starts, and I can take a picture, and approve it. My onActivityResult() then gets called. But my file doesn't get written. The URI is: file:///data/data/com.droidstogo.boom1/files/parked.jpg I can create thumbnail OK (by not putting the extra into the Intent), and can write that file OK, and later read it back). Can anyone see what simple mistake I am making? Nothing obvious shows up in the logcat - the camera is clearly taking the picture. Thanks, Peter

  • Android Web App : Position:fixed broken?

    - by StevenGilligan
    Hi all, I'm in the process of developping a Web Application for mobiles. I went with web applications because to me it seems a winning situation having to develop one application that could run also on iPhone / Windows Mobile / Palm etc. I started testing today after a few days of doing concepts, ideas and designs and what I wanted to do was have a menu that sticks at the bottom of the page. Exactly like the menu on the bottom in this iPhone application screenshot : http://farm4.static.flickr.com/3094/2656904921_1c54e93b4f.jpg Using CSS, I though it would be really easy to do this. Only using position:fixed; bottom:0; would have done the trick but I have found it doesn't behave the same on mobile browsers I tried to split my page in 2 sections : 1 would be a scrollable div (for the content) and the other one would be the bottom menu. Scrollable divs also do not work on Android. I also tried using frames with no luck either. Does anyone know of any way to re-create a menu that would stick to the bottom of a page for mobile phones? Thank you, Steven

  • CPU friendly infinite loop

    - by Adi
    Writing an infinite loop is simple: while(true){ //add whatever break condition here } But this will trash the CPU performance. This execution thread will take as much as possible from CPU's power. What is the best way to lower the impact on CPU? Adding some Thread.Sleep(n) should do the trick, but setting a high timeout value for Sleep() method may indicate an unresponsive application to the operating system. Let's say I need to perform a task each minute or so in a console app. I need to keep Main() running in an "infinite loop" while a timer will fire the event that will do the job. I would like to keep Main() with the lowest impact on CPU. What methods do you suggest. Sleep() can be ok, but as I already mentioned, this might indicate an unresponsive thread to the operating system. LATER EDIT: I want to explain better what I am looking for: I need a console app not Windows service. Console apps can simulate the Windows services on Windows Mobile 6.x systems with Compact Framework. I need a way to keep the app alive as long as the Windows Mobile device is running. We all know that the console app runs as long as its static Main() function runs, so I need a way to prevent Main() function exit. In special situations (like: updating the app), I need to request the app to stop, so I need to infinitely loop and test for some exit condition. For example, this is why Console.ReadLine() is no use for me. There is no exit condition check. Regarding the above, I still want Main() function as resource friendly as possible. Let asside the fingerprint of the function that checks for the exit condition.

  • Why do i get exc bad access in cases when object is not nil?

    - by DixieFlatline
    I have an app that receives remote notifications. My view controller that is shown after push has a tableview. App crashes very randomly (1 in 20 tries) at line setting frame: if (!myTableView) { NSLog(@"self.myTableView is nil"); } myTableView.frame=CGRectMake(0, 70, 320, 376); This only happens when i open the app, then open some other apps and then receive the push notification. I guess it has something to do with memory. I use ARC (ios 5). The strange thing is that nslog is not displayed, so tableview is not nil. Crash log: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x522d580c Crashed Thread: 0 Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 libobjc.A.dylib 0x352b1f7e objc_msgSend + 22 1 Foundation 0x37dc174c NSKVOPendingNotificationCreate + 216 2 Foundation 0x37dc1652 NSKeyValuePushPendingNotificationPerThread + 62 3 Foundation 0x37db3744 NSKeyValueWillChange + 408 4 Foundation 0x37d8a848 -[NSObject(NSKeyValueObserverNotification) willChangeValueForKey:] + 176 5 Foundation 0x37e0ca14 _NSSetPointValueAndNotify + 76 6 UIKit 0x312af25a -[UIScrollView(Static) _adjustContentOffsetIfNecessary] + 1890 7 UIKit 0x312cca54 -[UIScrollView setFrame:] + 548 8 UIKit 0x312cc802 -[UITableView setFrame:] + 182 9 POViO 0x000913cc -[FeedVC viewWillAppear:] (FeedVC.m:303) Dealloc is not called because it is not logged: - (void)dealloc { NSLog(@"dealloc"); }

  • How to use URLClassLoader to load a *.class file?

    - by DeletedAccount
    I'm playing around with Reflection and I thought I'd make something which loads a class and prints the names of all fields in the class. I've made a small hello world type of class to have something to inspect: kent@rat:~/eclipsews/SmallExample/bin$ ls IndependentClass.class kent@rat:~/eclipsews/SmallExample/bin$ java IndependentClass Hello! Goodbye! kent@rat:~/eclipsews/SmallExample/bin$ pwd /home/kent/eclipsews/SmallExample/bin kent@rat:~/eclipsews/SmallExample/bin$ Based on the above I draw two conclusions: It exists at /home/kent/eclipsews/SmallExample/bin/IndependentClass.class It works! (So it must be a proper .class-file which can be loaded by a class loader) Then the code which is to use Reflection: (Line which causes an exception is marked) import java.lang.reflect.Field; import java.net.MalformedURLException; import java.net.URL; import java.net.URLClassLoader; public class InspectClass { @SuppressWarnings("unchecked") public static void main(String[] args) throws ClassNotFoundException, MalformedURLException { URL classUrl; classUrl = new URL("file:///home/kent/eclipsews/SmallExample/bin/IndependentClass.class"); URL[] classUrls = { classUrl }; URLClassLoader ucl = new URLClassLoader(classUrls); Class c = ucl.loadClass("IndependentClass"); // LINE 14 for(Field f: c.getDeclaredFields()) { System.out.println("Field name" + f.getName()); } } } But when I run it I get: Exception in thread "main" java.lang.ClassNotFoundException: IndependentClass at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at InspectClass.main(InspectClass.java:14) My questions: What am I doing wrong above? How do I fix it? Is there a way to load several class files and iterate over them?

  • Serialize XML child and keep namespaces in Java

    - by Guido García
    I have an Document object that is modeling a XML like this one: <RootNode xmlns="http://a.com/a" xmlns:b="http://b.com/b"> <Child /> </RootNode> Using Java DOM, I need to get the <Child> node and serialize it to XML, but keeping the root node namespaces. This is what I currently have, but it does not serialize the namespaces: public static void main(String[] args) throws Exception { String xml = "<RootNode xmlns='http://a.com/a' xmlns:b='http://b.com/b'><Child /></RootNode>"; DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder(); Document doc = builder.parse(new ByteArrayInputStream(xml.getBytes())); Node childNode = doc.getFirstChild().getFirstChild(); // serialize to string StringWriter sw = new StringWriter(); DOMSource domSource = new DOMSource(childNode); StreamResult streamResult = new StreamResult(sw); TransformerFactory tf = TransformerFactory.newInstance(); Transformer serializer = tf.newTransformer(); serializer.transform(domSource, streamResult); String serializedXML = sw.toString(); System.out.println(serializedXML); } Current output: <?xml version="1.0" encoding="UTF-8"?> <Child/> Expected output: <?xml version="1.0" encoding="UTF-8"?> <Child xmlns='http://a.com/a' xmlns:b='http://b.com/b' />

  • GetEffectiveRightsFromAcl throws invalid acl error

    I am trying to get the effective rights a user has on a file using interop in C#. Following is the code I am using : public static FileSystemRights GetFileEffectiveRights(string FileName, string UserName) { IntPtr pDacl, pZero = IntPtr.Zero; int Mask = 0; uint errorReturn = GetNamedSecurityInfo(FileName, SE_OBJECT_TYPE.SE_FILE_OBJECT, SECURITY_INFORMATION.Dacl , out pZero, out pZero, out pDacl, out pZero, out pZero); if (errorReturn != 0) { throw new Exception("Win error : " + errorReturn); } Program.TRUSTEE pTrustee = new TRUSTEE(); pTrustee.pMultipleTrustee = IntPtr.Zero; pTrustee.MultipleTrusteeOperation = (int)Program.MULTIPLE_TRUSTEE_OPERATION.NO_MULTIPLE_TRUSTEE; pTrustee.ptstrName = UserName; pTrustee.TrusteeForm = (int)Program.TRUSTEE_FORM.TRUSTEE_IS_NAME; pTrustee.TrusteeType = (int)Program.TRUSTEE_TYPE.TRUSTEE_IS_USER; errorReturn = GetEffectiveRightsFromAcl(pDacl, ref pTrustee, ref Mask); if (errorReturn != 0) { throw new Exception("Win error : " + errorReturn); } return (FileSystemRights)Mask; } This code works fine until I start modifying the ACL structure using the classes FileAccessRule and FileInfo, and then I start getting Windows Error 1336 : ERROR_INVALID_ACL. Same is the case if I debug the process call GetFileEffectiveRights once, pause the process,change the ACL through windows API, and resume and call GetFileEffectiveRights again(the 1st call succeeds but the second gives 1336.) What is going wrong?

  • My Rails app is returning HTTP 500 for all its URLs, but nothing shows up in the log file. How can I

    - by mipadi
    I have a Rails app that is running on a production server with Apache and Phusion Passenger. The app works fine locally when using Mongrel, but whenever I try to load a URL on the production server, it returns HTTP 500. I know the server is working properly, because I can get the static elements of the application (e.g., JavaScript files, stylesheets, images) just fine. I've also checked the Passenger status and it is loading the app (it must be, since the app's 500 Internal Server Error page is returned, not just the default Apache one). Also, when I load the app via script/console production and do something like app.get("/"), 500 is also returned. The problem is that there is nothing in the log files to indicate the problem. production.log is empty. The Apache error logs show no problems with Apache, either. I'm stumped as to what's going on and I'm not sure how to diagnose the problem. I know I may have been a bit vague, but can anyone give a suggestion on what the problem may be? Or at least a way I can go about diagnosing it?

Languages will differ in content, numbers of pages, etc. 2. The content is mostly text. I would like the URLs to look some thing like this - www.domain.com/en/Home/Index, www.domain.nl/nl/Home/Index. But the last one should also work with - www.domain.nl/Home/Index - Witch is the exciting URLs. I have implemented Phil Haacks areas ViewEngine from this blogpost - http://haacked.com/archive/2008/11/04/areas-in-aspnetmvc.aspx. But only putting the English website in the areas and keeping the Dutch in old structure. Witch are served as Phils default fallback. But the problem is here that I have to duplicate my controllers for both language's. So I tried the work method described in this tread - http://stackoverflow.com/questions/1712167/asp-net-mvc-localization-route. It works OK with the ?en? and /nl/ but not with the old URLs. When using this code in the global.asax the URL without the culture isn't working. public static void RegisterRoutes(RouteCollection routes) { //routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{culture}/{controller}/{action}/{id}", // URL with parameters new { culture = "nl-NL", controller = "Home", action = "Index", id = "" } // Parameter defaults ); routes.MapRoute( "DefaultWitoutCulture", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I properly overlooking some thing simple but I can't get this to work for me. Or are there a better way of doing this?

  • How to add XmlInclude attribute dynamically

    - by Anindya Chatterjee
    I have the following classes [XmlRoot] public class AList { public List<B> ListOfBs {get; set;} } public class B { public string BaseProperty {get; set;} } public class C : B { public string SomeProperty {get; set;} } public class Main { public static void Main(string[] args) { var aList = new AList(); aList.ListOfBs = new List<B>(); var c = new C { BaseProperty = "Base", SomeProperty = "Some" }; aList.ListOfBs.Add(c); var type = typeof (AList); var serializer = new XmlSerializer(type); TextWriter w = new StringWriter(); serializer.Serialize(w, aList); } } Now when I try to run the code I got an InvalidOperationException at last line saying that The type XmlTest.C was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically. I know that adding a [XmlInclude(typeof(C))] attribute with [XmlRoot] would solve the problem. But I want to achieve it dynamically. Because in my project class C is not known prior to loading. Class C is being loaded as a plugin, so it is not possible for me to add XmlInclude attribute there. I tried also with TypeDescriptor.AddAttributes(typeof(AList), new[] { new XmlIncludeAttribute(c.GetType()) }); before var type = typeof (AList); but no use. It is still giving the same exception. Does any one have any idea on how to achieve it?

  • Comparable and Comparator contract with regards to null

    - by polygenelubricants
    Comparable contract specifies that e.compareTo(null) must throw NullPointerException. From the API: Note that null is not an instance of any class, and e.compareTo(null) should throw a NullPointerException even though e.equals(null) returns false. On the other hand, Comparator API mentions nothing about what needs to happen when comparing null. Consider the following attempt of a generic method that takes a Comparable, and return a Comparator for it that puts null as the minimum element. static <T extends Comparable<? super T>> Comparator<T> nullComparableComparator() { return new Comparator<T>() { @Override public int compare(T el1, T el2) { return el1 == null ? -1 : el2 == null ? +1 : el1.compareTo(el2); } }; } This allows us to do the following: List<Integer> numbers = new ArrayList<Integer>( Arrays.asList(3, 2, 1, null, null, 0) ); Comparator<Integer> numbersComp = nullComparableComparator(); Collections.sort(numbers, numbersComp); System.out.println(numbers); // "[null, null, 0, 1, 2, 3]" List<String> names = new ArrayList<String>( Arrays.asList("Bob", null, "Alice", "Carol") ); Comparator<String> namesComp = nullComparableComparator(); Collections.sort(names, namesComp); System.out.println(names); // "[null, Alice, Bob, Carol]" So the questions are: Is this an acceptable use of a Comparator, or is it violating an unwritten rule regarding comparing null and throwing NullPointerException? Is it ever a good idea to even have to sort a List containing null elements, or is that a sure sign of a design error?

  • event flow in action script 3

    - by Shay
    i try to dispatch a custom event from some component on the stage and i register other component to listen to it but the other component doesn't get the event here is my code what do i miss public class Main extends MovieClip //main document class { var compSource:Game; var compMenu:Menu; public function Main() { compSource = new Game; compMenu = new Menu(); var mc:MovieClip = new MovieClip(); addChild(mc); mc.addChild(compSource); // the source of the event - event dispatch when clicked btn mc.addChild(compMenu); //in init of that Movie clip it add listener to the compSource events } } public class Game extends MovieClip { public function Game() { btn.addEventListener(MouseEvent.CLICK, onFinishGame); } private function onFinishGame(e:MouseEvent):void { var score:Number = Math.random() * 100 + 1; dispatchEvent(new ScoreChanged(score)); } } public class Menu extends MovieClip { //TextField score public function Menu() { addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event):void { removeEventListener(Event.ADDED_TO_STAGE, init); //on init add listener to event ScoreChanged addEventListener(ScoreChanged.SCORE_GAIN, updateScore); } public function updateScore(e:ScoreChanged):void { //it never gets here! tScore.text = String(e._score); } } public class ScoreChanged extends Event { public static const SCORE_GAIN:String = "SCORE_GAIN"; public var _score:Number; public function ScoreChanged( score:Number ) { trace("new score"); super( SCORE_GAIN, true); _score = score; } } I don't want to write in Main compSource.addEventListener(ScoreChanged.SCORE_GAIN, compMenu.updateScore); cause i dont want the the compSource will need to know about compMenu its compMenu responsibility to know to what events it needs to listen.... any suggestions? Thanks!

  • How to add share menu item to Gallery by code

    - by Anthony
    I know how to implement this issue by Menuifest.xml, see also: Google Android Developer Group related issue But my question is how to add share menu of Gallery by java code not Menuifest.xml. My code is as below: public class MyActivity extends Activity { private static final String TAG = "MyActivity"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intent.ACTION_SEND); intentFilter.addCategory(Intent.CATEGORY_DEFAULT); try { intentFilter.addDataType("image/*"); } catch (MalformedMimeTypeException e) { Log.e(TAG, e.toString()); } Intent x = registerReceiver(new BroadcastReceiver() { public void onReceive(Context context, Intent intent) { Log.d(TAG, "Received intent "+intent); intent.setComponent(new ComponentName(context, Uploader.class)); startActivity(intent); } }, intentFilter); if (x==null) Log.i(TAG, "failed to regist a receiver"); else Log.i(TAG, "registed a receiver successfully"); // ... But registerReceiver always return null, and there is no menu added to Gallery's Share. Thank you. Anthony Xu

  • ObjectContext disposed puzzle

    - by jaklucky
    Hi, I have the follwing method. public List<MyEntity> GetMyEntities(MyObjectContext objCtx) { using(MyObjectContext ctx = objCtx ?? new MyObjectContext()) { retun ctx.MyEntities.ToList(); } } The idea is, user of this method can pass in the objectcontext if they have. If not then a new objectcontext will be created. If I am passing an object context to it, then it is getting disposed after the method is done. I was expecting only "ctx" variable gets disposed. If I write a small app, to know the using and dispose mechanism. It is acting differently. class TestClass : IDisposable { public int Number { get; set; } public string Str { get; set; } public ChildClass Child { get; set; } #region IDisposable Members public void Dispose() { Console.WriteLine("Disposed is called"); } #endregion } class ChildClass : IDisposable { public string StrChild { get; set; } #region IDisposable Members public void Dispose() { Console.WriteLine("Child Disposed is called"); } #endregion } class Program { static void Main(string[] args) { TestClass test = null; test = new TestClass(); test.Child = new ChildClass(); using (TestClass test1 = test ?? new TestClass()) { test1.Number = 1; test1.Str = "hi"; test1.Child.StrChild = "Child one"; test1.Child.Dispose(); } test.Str = "hi"; test.Child.StrChild = "hi child"; Console.ReadLine(); } } In this example, "test1"gets disposed but not "test". Where as in the first case both ctx and objCtx get disposed. Any ideas what is happening here with objectContext? Thank you, Suresh

  • Print a string that contains a certain pattern in Java

    - by jjpotter
    I am trying to find a regular expression within a line of a .csv file, so I can eventually save all the matches to another file, and lose all the other junk. So a line in my file might look like: MachineName,User,IP,VariableData,Location The VariableData is what I want to match, and if there's a match, print the line. I am using a pattern for this because I only want 3 out of 10 of variations of VariableData, and out of those 3, they are numbered differently(example, "pc104, pccrt102, pccart65"). I am trying to do this using the Scanner Class and keeping it simple as possible so I can understand it. Here is where I was heading with this...(the pattern isn't complete, just have it like this for testing). import java.io.File; import java.util.Scanner; import java.util.regex.Pattern; public class pcv { public static void main(String[] args) { File myFile = new File("c:\\temp\\report.csv"); Pattern myPat = Pattern.compile("pc"); try{ Scanner myScan = new Scanner(myFile); while(myScan.hasNext()){ if(myScan.hasNext(myPat)){ System.out.println("Test"); } } }catch(Exception e){ } } } This code loops, im guessing the .hasNext() methods are resetting themselves. I've played around with the Matcher class a little bit, but only found a way to match the expression but not get the whole line. My other throught was maybe somehow count the line that contains the pattern, then go back and print the line that corresponds to the counts.
