  • how can I enter character "<" in strings.xml?

    - by yrajabi
    I want to enter string " -< " in strings.xml file, the string has character < and I couldn't add it to xml file without error! I even tried to escaping by \ character: <string name="search_target_arrow"> -\< </string> or enclosing it between "" as below: <string name="search_target_arrow">" -< "</string> but none worked. Maybe I'm very amateur at this and the answer is not hard for you. so please tell me how you add such special chars in strings.xml?

  • looking for RTF template system with simple DSL

    - by 01
    Is there any framework that fills up rtf document with data? The idea is to make business people/testers change the document in MsWord and than generate reports from that. The problem is with tables, Id need to create some special DSL for handling tables and showing hidding text/page parts. Id rather not do that and use some existing solution. I tried to search for something, but I only found frameworks that can produce rtf output from xml input and i want to use rtf as input and output.

  • log file not generated while accessing a jar having log4j support.

    - by naveen garimella
    I have a x.jar which is being used by some client y.jar. Both x.jar and y.jar are at the same package level. i have put the log4j.xml at the same package level. But the log file is never generated. Can i know why? I have tried few other options as well but no luck till now. i have added log4j-1.2.16.jar to ClassPath: variable in manifest files of both x.jar and y.jar. Put log4j.xml at the class level of y.jar which actually calls the x.jar classes. package structure is as follows: x.jar --manifest.mf has a entry ClassPath:log4j-1.2.16.jar y.jar --manifest.mf has a entry ClassPath:log4j-1.2.16.jar log4j-1.2.16.jar log4j.xml --has a RollingFileAppender. Can any one suggest whether i am missing anything?

  • WeakHashMap iteration and garbage collection

    - by Shamik
    I am using a WeaekHashMap to implement a Cache. I am wondering if I am iterating over the keys of this map, and at the same time garbage collector is actively removing keys from this map, would I receive a ConcurrentModificationException ? I do not think so, because as far as I understand, concurrentmodificationexception happens because of bugs in the application code where the developer forgot to understand that the same map is shared/used by other threads and in this case, it should not happen. But wondering how would JVM handle this when WeakHashMap is not synchronized ?

  • Implementing deadlock condition

    - by Bhaskar
    I am trying to implementing deadlock condition but somehow I am not able to get it working. Both the threads Thread1 and Thread2 are entering in the run function but only one of them enters in Sub/Sum depending on who entered run first. Example : if Thread2 entered run first the it will call sub() and Thread1 never calls sum(). I have also added sleep time so that Thread2 sleeps before calling sum() and Thread1 gets enough time to enter Sum() but Thread1 never enters. public class ExploringThreads { public static void main(String[] args) { // TODO Auto-generated method stub threadexample a1 = new threadexample(); Thread t1 = new Thread(a1, "Thread1"); Thread t2 = new Thread(a1,"Thread2"); t1.start(); t2.start(); } } class threadexample implements Runnable{ public int a = 10; public void run(){ if(Thread.currentThread().getName().equals("Thread1")) sum(); else if(Thread.currentThread().getName().equals("Thread2")) sub(); } public synchronized void sum() { try { Thread.sleep(2000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println(Thread.currentThread().getName()+"In Sum"); sub(); } public synchronized void sub() { try { Thread.sleep(2000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println(Thread.currentThread().getName()+"In Sub"); sum(); } }

  • Possible to skip track from an Android application?

    - by parse
    I'm planning on doing a application for Android 2.1 that changes song every minute (through what I hope exists in Android, "next") for the application using the audio device atm. So if I have Spotify running in background already, playing music, can I through my program change to the next track? Let me know if I was unclear about anything. Thanks in advance!

  • When i add a bitmap to an array list the last element is duplicated in previous indexes

    - by saxofone2
    I'm trying to implement a personal way of undo/redo in a finger paint-like app. I have in synthesis three objects: the Main class (named ScorePadActivity), the relative Main Layout (with buttons, menus, etc, as well as a View object where I create my drawings), and a third object named ArrayList where i'm writing the undo/redo code. The problem is, when I press the undo button nothing happens, but if I draw anything again "one-time" and press undo, the screen is updated. If I draw many times, to see any changes happen on screen I have to press the undo button the same number of times I have drawn. Seems like (as in title) when I add a bitmap to the array list the last element is duplicated in previous indexes, and for some strange reason, everytime I press the Undo Button, the system is ok for one time, but starts to duplicate until the next undo. The index increase is verified with a series of System.out.println inserted in code. Now when I draw something on screen, the array list is updated with the code inserted after the invocation of touchup(); method in motionEvent touch_up(); } this.arrayClass.incrementArray(mBitmap); mPath.rewind(); invalidate(); and in ArrayList activity; public void incrementArray(Bitmap mBitmap) { this._mBitmap=mBitmap; _size=undoArray.size(); undoArray.add(_size, _mBitmap); } (All Logs removed for clear reading) The undo button in ScorePadActivity calls the undo method in View activity: Button undobtn= (Button)findViewById(R.id.undo); undobtn.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { mView.undo(); } }); in View activity: public void undo() { this.mBitmap= arrayClass.undo(); mCanvas = new Canvas(mBitmap); mPath.rewind(); invalidate(); } that calls the relative undo method in ArrayList activity: public Bitmap undo() { // TODO Auto-generated method stub _size=undoArray.size(); if (_size>1) { undoArray.remove(_size-1); _size=undoArray.size(); _mBitmap = ((Bitmap) undoArray.get(_size-1)).copy(Bitmap.Config.ARGB_8888,true); } return _mBitmap; } return mBitmap and invalidate: Due to my bad English I have made a scheme to make the problem more clear: I have tried with HashMap, with a simple array, I have tried to change mPath.rewind(); with reset();, new Path(); etc but nothing. Why? Sorry for the complex answer, i want give you a great thanks in advance. Best regards

  • struts annotation issue

    - by Gourav
    My issue is that i have an annotation in Struts2 action class like private String[] origfilenofrom; @FieldExpressionValidator(fieldName="origfilenofrom",key="",message="File Length should be 12 for old file format and 15 for new file format",expression="checkorigFileFormat(origfilenofrom)") now my mehtod is public boolean checkorigFileFormat(String[] files ) { for(int counter=0;counter<files.length;counter++) { int n=files[counter].length(); if(!(n==12 || n==15)) { return false; } } return true; } So for any string in that string [], which is returning false the value is bei false. No matter 3 strings in that string [] are true if one is false then the annotaion message is displayed for all. I want the message not to display where the string is true. Help please

  • specifying ThreadPoolExecutor problem

    - by Sarmun
    Is there any way to create Executor that will have always at least 5 threads, and maximum of 20 threads, and unbounded queue for tasks (meaning no task is rejected) I tried new ThreadPoolExecutor(5, 20, 60L, TimeUnit.SECONDS, queue) with all possibilities that I thought of for queue: new LinkedBlockingQueue() // never runs more than 5 threads new LinkedBlockingQueue(1000000) // runs more than 5 threads, only when there is more than 1000000 tasks waiting new ArrayBlockingQueue(1000000) // runs more than 5 threads, only when there is more than 1000000 tasks waiting new SynchronousQueue() // no tasks can wait, after 20, they are rejected and none worked as wanted.

    I have some classes in my current project which have the wrong package declaration (they are in the wrong folder for their declared package.) Unfortunately, fixing the problem by moving the class is not an option. Is there a way I can get eclipse to ignore the error?

It always gives me 0(Zero); When I checked with position of byte array; it shows me correct value. Is there any kind padding require?
