• Any techniques to interrupt, kill, or otherwise unwind (releasing synchronization locks) a single de

  - by gojomo

  I have a long-running process where, due to a bug, a trivial/expendable thread is deadlocked with a thread which I would like to continue, so that it can perform some final reporting that would be hard to reproduce in another way. Of course, fixing the bug for future runs is the proper ultimate resolution. Of course, any such forced interrupt/kill/stop of any thread is inherently unsafe and likely to cause other unpredictable inconsistencies. (I'm familiar with all the standard warnings and the reasons for them.) But still, since the only alternative is to kill the JVM process and go through a more lengthy procedure which would result in a less-complete final report, messy/deprecated/dangerous/risky/one-time techniques are exactly what I'd like to try. The JVM is Sun's 1.6.0_16 64-bit on Ubuntu, and the expendable thread is waiting-to-lock an object monitor. Can an OS signal directed to an exact thread create an InterruptedException in the expendable thread? Could attaching with gdb, and directly tampering with JVM data or calling JVM procedures allow a forced-release of the object monitor held by the expendable thread? Would a Thread.interrupt() from another thread generate a InterruptedException from the waiting-to-lock frame? (With some effort, I can inject an arbitrary beanshell script into the running system.) Can the deprecated Thread.stop() be sent via JMX or any other remote-injection method? Any ideas appreciated, the more 'dangerous', the better! And, if your suggestion has worked in personal experience in a similar situation, the best!

• Java Days & Bookings

  - by sys_debug

  Ok this is an extension of a question I asked about earlier yet this is the next step that is unclear to me. Everything else will be ready and this part is driving me mad! some members provided great help and I already made progress with that info, but this is just another obstacle. I am creating a booking object (as was suggested) that will have a start date and end date. each booking will also have a number of seats associated with it (that I require to reserve). The total available number of seats any given day 46 (as the total capacity of the hall is 46 seats). so in assumption that I have a booking to be made in the system, and start date is 1st jan and end date is 10th jan. The question is how can I check the remaining seats in all those days between the range to see if requested number could be hosted or not? and then when the second booking is made, it will have to see that the days in this range already have less than 46 and decrement further if possible to host the reservation. one of the members, and I appreciate his effort, gladly contributed a method to compare if this booking is after or before the existing bookings. The code provided is here: public boolean overlapsWithExisting(Booking booking) { final Date early = booking.getStart(); final Date late = booking.getEnd(); for(Booking existing : existingBookings) { if(!(early.isAfter(existing.getEnd() || late.isBefore(existing.getStart())) return true; } return false; } I just want to know how to associate 46 with each day and keep record of days that are decremented by bookings. Thanks and reallllllly appreciated :D

• ProgressDialog won't show, even in onPreExecute of AsyncTask

  - by Geltrude

  In my class, Main extends Activity, I've this: @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch (requestCode) { case ... case CREDENTIAL_VIEW: new SetStatusProgressBar(this).execute(); And there is this nested class: private class SetStatusProgressBar extends AsyncTask<String, Void, Boolean> { private ProgressDialog dialog; private Main ctx; public SetStatusProgressBar(Main ctx) { this.ctx = ctx; dialog = new ProgressDialog(ctx); } // progress dialog to show user that contacting server. protected void onPreExecute() { this.dialog = ProgressDialog.show(ctx, null, "Refreshing data from server...", true, false); } @Override protected void onPostExecute(final Boolean success) { //... //statements that refresh UI //... if (dialog.isShowing()) { dialog.dismiss(); timerProgressBarStop(); } } protected Boolean doInBackground(final String... args) { //... //statements to download data from server //... return true; } } In the Main class I open a second Activity, in this way: Intent myIntent = new Intent(Main.this, Credentials.class); startActivityForResult(myIntent, CREDENTIAL_VIEW); That second Activity returns to the Main activity in this way: Intent intent = new Intent(); setResult(RESULT_OK, intent); finish(); I don't understand why when I navigate from the second Activity to the Main, the ProgressDialog will show ONLY AFTER that the UI refreshes... In this way the Progress Dialog stays on the screen only for half second... and then hides! :( I'd like to see the ProgressDialog on top during all the download time! Help, please. Thank you all

• Why null reference exception in SetMolePublicInstance?

  - by OldGrantonian

  I get a "null reference" exception in the following line: MoleRuntime.SetMolePublicInstance(stub, receiverType, objReceiver, name, null); The program builds and compiles correctly. There are no complaints about any of the parameters to the method. Here's the specification of SetMolePublicInstance, from the object browser: SetMolePublicInstance(System.Delegate _stub, System.Type receiverType, object _receiver, string name, params System.Type[] parameterTypes) Here are the parameter values for "Locals": + stub {Method = {System.String <StaticMethodUnitTestWithDeq>b__0()}} System.Func<string> + receiverType {Name = "OrigValue" FullName = "OrigValueP.OrigValue"} System.Type {System.RuntimeType} objReceiver {OrigValueP.OrigValue} object {OrigValueP.OrigValue} name "TestString" string parameterTypes null object[] I know that TestString() takes no parameters and returns string, so as a starter to try to get things working, I specified "null" for the final parameter to SetMolePublicInstance. As already mentioned, this compiles OK. Here's the stack trace: Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.ExtendedReflection.Collections.Indexable.ConvertAllToArray[TInput,TOutput](TInput[] array, Converter`2 converter) at Microsoft.Moles.Framework.Moles.MoleRuntime.SetMole(Delegate _stub, Type receiverType, Object _receiver, String name, MoleBindingFlags flags, Type[] parameterTypes) at Microsoft.Moles.Framework.Moles.MoleRuntime.SetMolePublicInstance(Delegate _stub, Type receiverType, Object _receiver, String name, Type[] parameterTypes) at DeqP.Deq.Replace[T](Func`1 stub, Type receiverType, Object objReceiver, String name) in C:\0VisProjects\DecP_04\DecP\DeqC.cs:line 38 at DeqPTest.DecCTest.StaticMethodUnitTestWithDeq() in C:\0VisProjects\DecP_04\DecPTest\DeqCTest.cs:line 28 at Starter.Start.Main(String[] args) in C:\0VisProjects\DecP_04\Starter\Starter.cs:line 14 Press any key to continue . . . To avoid the null parameter, I changed the final "null" to "parameterTypes" as in the following line: MoleRuntime.SetMolePublicInstance(stub, receiverType, objReceiver, name, parameterTypes); I then tried each of the following (before the line): int[] parameterTypes = null; // if this is null, I don't think the type will matter int[] parameterTypes = new int[0]; object[] parameterTypes = new object[0]; // this would allow for various parameter types All three attempts produce a red squiggly line under the entire line for SetMolePublicInstance Mouseover showed the following message: The best overloaded method match for 'Microsoft.Moles.Framework.Moles.MoleRuntime.SetMolePublicInstance(System.Delegate, System.Type, object, string, params System.Type[])' has some invalid arguments. I'm assuming that the first four arguments are OK, and that the problem is with the params array.

• How do I capture Chinese input via SCIM with STDIN in Perl?

  - by KCArpe

  I use SCIM on Linux for Chinese and Japanese language input. Unfortunately, when I try to capture input using Perl's STDIN, the input is crazy. As roman characters are typed, SCIM tries to guess the correct final characters. ^H (backspace) codes are used to delete previously suggested chars on the command line. (As you type, SCIM tries to guess final Asian chars and displays them.) However, these backspace chars are shown literally as ^H and not interpreted correctly. Example one-liner: perl -e 'print "Chinese: "; my $s = <STDIN>; print $s' When I enable SCIM Chinese or Japanese language input, as I type, e.g., nihao = ??, here is the result: ?^H?^H?^H?^H?^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H?? At the very end of this string, you can see "??" (nihao/hello). At a normal bash prompt, if I type nihao (with Chinese enabled), the results is perfect. This has something to do with interpretation of backspace chars (or control chars) during Perl's STDIN. The same thing happens when using command 'read' in Bash. Witness: read -p 'Chinese: ' s && echo $s

• Is this use of PreparedStatements in a Thread in JAVA correct?

  - by Gormcito

  I'm still an undergrad just working part time and so I'm always trying to be aware of better ways to do things. Recently I had to write a program for work where the main thread of the program would spawn "task" threads (for each db "task" record) which would perform some operations and then update the record to say that it has finished. Therefore I needed a database connection object and PreparedStatement objects in or available to the ThreadedTask objects. This is roughly what I ended up writing, is creating a PreparedStatement object per thread a waste? I thought static PreparedStatments could create race conditions... Thread A stmt.setInt(); Thread B stmt.setInt(); Thread A stmt.execute(); Thread B stmt.execute(); A´s version never gets execed.. Is this thread safe? Is creating and destroying PreparedStatement objects that are always the same not a huge waste? public class ThreadedTask implements runnable { private final PreparedStatement taskCompleteStmt; public ThreadedTask() { //... taskCompleteStmt = Main.db.prepareStatement(...); } public run() { //... taskCompleteStmt.executeUpdate(); } } public class Main { public static final db = DriverManager.getConnection(...); }

• Is there a quality, file-size, or other benefit to JPEG sizes being multiples of 8px or 16px?

  - by davebug

  The JPEG compression encoding process splits a given image into blocks of 8x8 pixels, working with these blocks in future lossy and lossless compressions. [source] It is also mentioned that if the image is a multiple 1MCU block (defined as a Minimum Coded Unit, 'usually 16 pixels in both directions') that lossless alterations to a JPEG can be performed. [source] I am working with product images and would like to know both if, and how much benefit can be derived from using multiples of 16 in my final image size (say, using an image with size 480px by 360px) vs. a non-multiple of 16 (such as 484x362). In this example I am not interested in further alterations, editing, or recompression of the final image. To try to get closer to a specific answer where I know there must be largely generalities: Given a 480x360 image that is 64k and saved at maximum quality in Photoshop [example]: Can I expect any quality loss from an image that is 484x362 What amount of file size addition can I expect (for this example, the additional space would be white pixels) Are there any other disadvantages to growing larger than the 8px grid? I know it's arbitrary to use that specific example, but it would still be helpful (for me and potentially any others pondering an image size) to understand what level of compromise I'd be dealing with in breaking the non-8px grid. The key issue here is a debate I've had is whether 8-pixel divisible images are higher quality than images that are not divisible by 8-pixels.

• android listview order changed when called notifyDataSetChanged

  - by 9nix00

  hi,all. when I use notifyDataSetChanged(), the listview display order will be change . like this 3 2 1 when current activy was created. but when I change the data. it will be 1 2 3 I don't want the order changed and i dont understand why its happening. This is a piece of code from my adapter class public static class ItemAdapter extends BaseAdapter { private String[] mData; private LayoutInflater mInflater; // I called this method to change data public void setEditText(int position, final String item) { mData[position] = item; notifyDataSetChanged(); } } I change data at some dialog like this builder = new AlertDialog.Builder(ct); builder.setTitle(R.string.pickStatus) .setView(edBuffer) .setPositiveButton(R.string.save, new DialogInterface.OnClickListener() { @Override public void onClick( DialogInterface dialog, int id) { // TODO Auto-generated method stub canPop = true; final String tmp = edBuffer.getText().toString(); KbonezLog.e(String.format( "set into key %d", key)); //use mData key to set value setEditText(key, tmp); dialog.dismiss(); }})

• eclipse stuck at running program

  - by user1434388

  This is the picture after I end task the eclipse. My Android Program has no errors, and before this problem it was all fine. It happened when I added some code into my program. It gets stuck after I click the run button. This also happens when I run my handphone for debugging the program. Other programs are all working fine, only one is stuck. When I try to remove and import it again seem there is a classes.dex file which I cannot delete, I have to restart my computer for it to allow to delete and I have to force the program to close. I have searched at this website and they said keep open the emulator but it doesn't work for me. below is the connecting coding that i added. //check internet connection private boolean chkConnectionStatus(){ ConnectivityManager connMgr = (ConnectivityManager) this.getSystemService(Context.CONNECTIVITY_SERVICE); final android.net.NetworkInfo wifi = connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI); final android.net.NetworkInfo mobile = connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE); if( wifi.isAvailable() ){ return true; } else if( mobile.isAvailable() ){ return true; } else { Toast.makeText(this, "Check your internet" , Toast.LENGTH_LONG).show(); return false; } }

• Synchronize write to two collections

  - by glaz666

  I need to put some value to maps if it is not there yet. The key-value (if set) should always be in two collections (that is put should happen in two maps atomically). I have tried to implement this as follows: private final ConcurrentMap<String, Object> map1 = new ConcurrentHashMap<String, Object>(); private final ConcurrentMap<String, Object> map2 = new ConcurrentHashMap<String, Object>(); public Object putIfAbsent(String key) { Object retval = map1.get(key); if (retval == null) { synchronized (map1) { retval = map1.get(key); if (retval == null) { Object value = new Object(); //or get it somewhere synchronized (map2) { map1.put(key, value); map2.put(key, new Object()); } retval = value; } } } return retval; } public void doSomething(String key) { Object obj1 = map1.get(key); Object obj2 = map2.get(key); //do smth } Will that work fine in all cases? Thanks

• eliminating duplicate Enum code

  - by Don

  Hi, I have a large number of Enums that implement this interface: /** * Interface for an enumeration, each element of which can be uniquely identified by it's code */ public interface CodableEnum { /** * Get the element with a particular code * @param code * @return */ public CodableEnum getByCode(String code); /** * Get the code that identifies an element of the enum * @return */ public String getCode(); } A typical example is: public enum IMType implements CodableEnum { MSN_MESSENGER("msn_messenger"), GOOGLE_TALK("google_talk"), SKYPE("skype"), YAHOO_MESSENGER("yahoo_messenger"); private final String code; IMType (String code) { this.code = code; } public String getCode() { return code; } public IMType getByCode(String code) { for (IMType e : IMType.values()) { if (e.getCode().equalsIgnoreCase(code)) { return e; } } } } As you can imagine these methods are virtually identical in all implementations of CodableEnum. I would like to eliminate this duplication, but frankly don't know how. I tried using a class such as the following: public abstract class DefaultCodableEnum implements CodableEnum { private final String code; DefaultCodableEnum(String code) { this.code = code; } public String getCode() { return this.code; } public abstract CodableEnum getByCode(String code); } But this turns out to be fairly useless because: An enum cannot extend a class Elements of an enum (SKYPE, GOOGLE_TALK, etc.) cannot extend a class I cannot provide a default implementation of getByCode(), because DefaultCodableEnum is not itself an Enum. I tried changing DefaultCodableEnum to extend java.lang.Enum, but this doesn't appear to be allowed. Any suggestions that do not rely on reflection? Thanks, Don

• Controlling race condition at startup.

  - by Will Hartung

  I have some code that I want to have some one time initialisation performed. But this code doesn't have a definite lifecycle, so my logic can be potentially invoked by multiple threads before my initialisation is done. So, I want to basically ensure that my logic code "waits" until initialisation is done. This is my first cut. public class MyClass { private static final AtomicBoolean initialised = new AtomicBoolean(false); public void initialise() { synchronized(initialised) { initStuff(); initialised.getAndSet(true); initialised.notifyAll(); } } public void doStuff() { synchronized(initialised) { if (!initialised.get()) { try { initialised.wait(); } catch (InterruptedException ex) { throw new RuntimeException("Uh oh!", ex); } } } doOtherStuff(); } } I basically want to make sure this is going to do what I think it's going to do -- block doStuff until the initialised is true, and that I'm not missing a race condition where doStuff might get stuck on a Object.wait() that will never arrive. Edit: I have no control over the threads. And I want to be able to control when all of the initialisation is done, which is why doStuff() can't call initialise(). I used an AtomicBoolean as it was a combination of a value holder, and an object I could synchronize. I could have also simply had a "public static final Object lock = new Object();" and a simple boolean flag. AtomicBoolean conveniently gave me both. A Boolean can not be modified. The CountDownLatch is exactly what I was looking for. I also considered using a Sempahore with 0 permits. But the CountDownLatch is perfect for just this task.

• Using MPI_Type_Vector and MPI_Gather, in C.

  - by Goloneg

  Hi, I am trying to multiply square matrices in parallele with MPI. I use a MPI_Type_vector to send square submatrixes (arrays of float) to the processes, so they can calculate subproducts. Then, for the next iterations, these submatrices are send to neighbours processes as MPI_Type_contiguous (the whole submatrix is sent). This part is working as expected, and local results are corrects. Then, I use MPI_Gather with the contiguous types to send all local results back to the root process. The problem is, the final matrix is build (obviously, by this method) line by line instead of submatrix by submatrix. I wrote an ugly procedure rearranging the final matrix, but I would like to know if there is a direct way of performing the "inverse" operation of sending MPI_Type_vectors (i.e., sending an array of values and directly arranging it in a subarray form in the receiving array). An example, to try and clarify my long text : A[16] and B[16] are 4x4 matrices to be multiplied ; C[16] will contain the result ; 4 processes are used (Pi with i from 0 to 3) : Pi gets two 2x2 submatrices : subAi[4] and subBi[4] ; their product is stored locally in subCi[4]. For instance, P0 gets : subA0[4] containing A[0], A[1], A[4] and A[5] ; subB0[4] containing B[0], B[1], B[4] and B[5]. After everything is calculed, root process gathers all subCi[4]. Then C[16] contains : [ subC0[0], subC0[1], subC0[2], subC0[3], subC1[0], subC1[1], subC1[2], subC1[3], subC2[0], subC2[1], subC2[2], subC2[3], subC3[0], subC3[1], subC3[2], subC3[3]] and I would like it to be : [ subC0[0], subC0[1], subC1[0], subC1[1], subC0[2], subC0[3], subC1[2], subC1[3], subC2[0], subC2[1], subC3[0], subC3[1], subC2[2], subC2[3], subC3[2], subC3[3]] without further operation. Does someone know a way ? Thanks for your advices.

• Limiting Row Selection in JTable

  - by Pat

  Is there an easy way to limit the total selection of rows in a JTable? I mean I'd like to allow the user to use shift and ctrl to select a maximum of X rows. If he clicks again on a row it would cancel out all the selections. Sort of how it currently behaves, but while limiting the total amount of selected rows. Here's my current implementation, I'm kind of clueless on how to limit the selection graphically. public class RoomsListView extends AbstractViewPanel { public RoomsListView(DefaultController controller) { this.controller = controller; initUI(); } private void initUI() { tableT = new JTable(RoomsModel.getInstance()); sorter = new TableRowSorter<RoomsModel>(RoomsModel.getInstance()); tableT.setRowSorter(sorter); tableT.setPreferredScrollableViewportSize(new Dimension(CUSTOM_TABLE_WIDTH, CUSTOM_TABLE_HEIGHT)); tableT.addMouseListener(new MouseAdapter() { public void mouseClicked(MouseEvent e) { rowClickedPerformed(e); } }); } private void rowClickedPerformed(MouseEvent e) { } public void modelPropertyChange(PropertyChangeEvent evt) { } public JTable getTable() { return tableT; } private final int CUSTOM_TABLE_WIDTH = -1; private final int CUSTOM_TABLE_HEIGHT = 150; private JTable tableT; private DefaultController controller; private TableRowSorter<RoomsModel> sorter; }

• Smarter println that shows the depth in the stack

  - by Hectoret

  I am using System.out.println in my code to track the execution of a program and get some useful output. This creates results like this in the console: Main function. Program starts. Method getArea. Getting values Method getSide. Side is 6 Method getArea. First value is 6 Method getSide. Side is 8 Method getArea. Second value is 8 Method getArea. Area is 48 Main function. The final area is 48 I would like to create tha method, which adds a space in front of the output every time the code goes deeper in the method call stack. For example, the same code but instead of using System.out.println, now with Misc.smartPrintln: Main function. Program starts. Method getArea. Getting values Method getSide. Side is 6 Method getArea. First value is 6 Method getSide. Side is 8 Method getArea. Second value is 8 Method getArea. Area is 48 Main function. The final area is 48 The method would have this definition: public static void smartPrintln(String string); I don't know how to implement this functionality. Any ideas how to solve this? And, could the use of a logger offer this functionality?

• Create table class as a singleton

  - by Mark

  I got a class that I use as a table. This class got an array of 16 row classes. These row classes all have 6 double variables. The values of these rows are set once and never change. Would it be a good practice to make this table a singleton? The advantage is that it cost less memory, but the table will be called from multiple threads so I have to synchronize my code which way cause a bit slower application. However lookups in this table are probably a very small portion of the total code that is executed. EDIT: This is my code, are there better ways to do this or is this a good practice? Removed synchronized keyword according to recommendations in this question. final class HalfTimeTable { private HalfTimeRow[] table = new HalfTimeRow[16]; private static final HalfTimeTable instance = new HalfTimeTable(); private HalfTimeTable() { if (instance != null) { throw new IllegalStateException("Already instantiated"); } table[0] = new HalfTimeRow(4.0, 1.2599, 0.5050, 1.5, 1.7435, 0.1911); table[1] = new HalfTimeRow(8.0, 1.0000, 0.6514, 3.0, 1.3838, 0.4295); //etc } @Override @Deprecated public Object clone() throws CloneNotSupportedException { throw new CloneNotSupportedException(); } public static HalfTimeTable getInstance() { return instance; } public HalfTimeRow getRow(int rownumber) { return table[rownumber]; } }

• Why is android:transcriptMode="normal" not working properly?

  - by BCS

  I've been doing a lot of fiddling with an issue I've been having. What happens is each time an item gets added to my listview (adapter) I expect it to auto-scroll if I'm at the last item (which it will do to an extent); HOWEVER, if 3 or more items get added at once, it will not auto-scroll. Here is the XML of that listview: <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:transcriptMode="normal"/> I tried a workaround using a snippet I found here. My code is as follows: public void addChat(final String text, final String username) { this.runOnUiThread(new Runnable() { public void run() { globals.chatAdapter.add(DateFormat.format("hh:mmaa", Calendar.getInstance()).toString(), username, text); globals.chatAdapter.notifyDataSetChanged(); int lastP = getListView().getLastVisiblePosition(); int count = globals.chatAdapter.getCount() - 1; if (lastP == globals.chatAdapter.oldP || lastP == -1) { getListView().setSelection(count); } globals.chatAdapter.oldP = count; } }); } The problem with this is when a bunch of items come in at once, getListView().getLastVisiblePosition() will not update right away causing a setSelection() to never get called, and thus no auto-scroll. Any suggestions?

• HTML templating in C++ and translations

  - by Karim

  I'm using HTML_Template for templating in my C++-based web app (don't ask). I chose that because it was very simple and it turns out to be a good solution. The only problem right now is that I would like to be able to include translatable strings in the HTML templates (HTML_Template does not really support that). Ultimately, what I would like is to have a single file that contains all the strings to be translated. It can then be given to a translator and plugged back in to the app and used depending on which language the user chose in settings. I've been going back and forth on some options and was wondering what others felt was the best choice (or if there's a better choice that isn't listed) Extend HTML_Template to include a tag for holding the literal string to translate. So, for example, in the HTML I would put something like <TMPL_TRANS "this is the text to translate"/> Use a completely separate scheme for translation and preprocess the HTML files to generate the final template files (without the special translation lingo). For example, in the pre-processed file, translatable text would look like this: {{this is the text to translate}} and the final would look like: this is the text to translate Don't do anything and let the translators find the string to translate in the html and js files themselves.

• Java Hibernate session delete of object

  - by user2535201

  I'm really struggling with hibernate sessions, I never have the result I expect when making a query on a modified session object. I think all my problems are related. The last one is the following : final Session iSession = AbstractDAO.getSessionFactory().openSession(); try { iSession.beginTransaction(); MyObject iObject = DAOMyObject.getInstance().get(iSession,ObjectId); iObject.setQuantity(0); //previously the quantity was different from zero DAOMyObject.getInstance().update(iSession,iObject); DAOMyObject.getInstance().deleteObjectWithZeroQuantities(iSession); iSession.getTransaction().commit(); } catch (final Exception aException) { iSession.getTransaction().rollback(); logger.error(aException.getMessage(), aException); throw aException; } finally { iSession.close(); } What I'm not getting is why the object is not deleted, since I'm modified it in the session, the query making the delete should find it. I had the same problem with creating an object with an incremental id in a session, then creating another one in the same session before the commit, with a select max(id)+1. But the session gets me the same number of id every time.

• Android AutocompleteView OnClickListener

  - by Chirag_RB

  I have 2 Auto Complete Views which i have to pre-populate with some text .However as soon as user clicks on the views , the text should disappear and allow user to enter text . I have written two separate on click listeners to do so . The On click listener for the first one is working fine . However i have to double click for the On click listener of the second one to work. Please find the chunk of code below and come up with some solution . final AutoCompleteTextView source = (AutoCompleteTextView) findViewById(R.id.source); ArrayAdapter source_adapter = new ArrayAdapter(this, R.layout.list_item, Model.City); source.setAdapter(source_adapter); source.setOnClickListener(new OnClickListener(){ public void onClick(View v) { source.setText(""); source.setTextSize(14); } }); final AutoCompleteTextView destination = (AutoCompleteTextView) findViewById(R.id.destination); ArrayAdapter destination_adapter = new ArrayAdapter(this, R.layout.list_item, Model.City); destination.setAdapter(destination_adapter); destination.setOnClickListener(new OnClickListener(){ public void onClick(View v) { destination.setText(""); destination.setTextSize(14); } });

• Accessing Application Scoped Bean Causes NullPointerException

  - by user2946861

  What is an Application Scoped Bean? I understand it to be a bean which will exist for the life of the application, but that doesn't appear to be the correct interpretation. I have an application which creates an application scoped bean on startup (eager=true) and then a session bean that tries to access the application scoped bean's objects (which are also application scoped). But when I try to access the application scoped bean from the session scoped bean, I get a null pointer exception. Here's excerpts from my code: Application Scoped Bean: @ManagedBean(eager=true) @ApplicationScoped public class Bean1 implements Serializable{ private static final long serialVersionUID = 12345L; protected ArrayList<App> apps; // construct apps so they are available for the session scoped bean // do time consuming stuff... // getters + setters Session Scoped Bean: @ManagedBean @SessionScoped public class Bean2 implements Serializable{ private static final long serialVersionUID = 123L; @Inject private Bean1 bean1; private ArrayList<App> apps = bean1.getApps(); // null pointer exception What appears to be happening is, Bean1 is created, does it's stuff, then is destroyed before Bean2 can access it. I was hoping using application scoped would keep Bean1 around until the container was shutdown, or the application was killed, but this doesn't appear to be the case.

• how to create a array of labelfields

  - by sheetal_r oswal

  I have 'n' number of data which has to be added to a label field which in turn has to be added to hfm.I am setting the single data in to label field as : final LabelField desc = new LabelField("", LabelField.FOCUSABLE); final LabelField desc1 = new LabelField("", LabelField.FOCUSABLE); Vector data = (Vector) listEvent.get(keys); for (int i = 0; i < data.size(); i++) { EventData ee = (EventData) data.elementAt(i); String Summary= ee.getSummary(); if (time.getText().equals(sTime)) { desc.setText(Summary); } else{ desc1.setText(Summary); } } HorizontalFieldManager horizontalFieldManager_left18 = new HorizontalFieldManager() { horizontalFieldManager_left18.add(desc1); vfm.add(horizontalFieldManager_left18); vfm.add(new SeparatorField()); HorizontalFieldManager horizontalFieldManager_left17 = new HorizontalFieldManager() { horizontalFieldManager_left17.add(desc); vfm.add(horizontalFieldManager_left17); vfm.add(new SeparatorField()); In the above code i loop over vector and set the data into labelfield and adding the label to hfm later. Now the case is the vector data has more than one summary data,and the data is getting overridden in labelfield,i need to keep 'n' number of summary data into lablefield and add to new hfm.

• Can't referr to my get method

  - by chility

  I have this amazing and good looking class: public class SayingsHolder extends Application{ ArrayList<String> SayingsList = new ArrayList<String>(){{ SayingsList.add("1"); SayingsList.add("2"); }}; public ArrayList<String> getSayingsList() { return SayingsList; } } Now I'm trying to call the getSayingsList method inside of my activity's FragmentStatePagerAdapter by: private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { final SayingsHolder holder = (SayingsHolder).getApplication(); } Everything fine for now, but when I make my code like this: private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { final SayingsHolder holder = (SayingsHolder).getApplication(); holder.getSayingsList(); } it says: Syntax error on token "getSayingsList", Identifier expected after this token The problem is that holder is not functional at all. What I mean is that when i type the this holder. the getSayingsList is not showing at all. What am I missing here? I know that it is an extremely small issue, but it seems that I can't spot it. My activity extends FragmentActivity if it's important It seems that I'm missing something here. I can't call my method anywhere in my activity. I'm starting a bounty, because I need an example.
