My app works in IDE but not when packaged as a JAR, advice please?
Hello,
I've written my application which seems to work perfectly in my IDE, however when I package the application into a JAR, the JavaVM isn't happy with it. When executed, the JVM crashes somewhere early in my program (I'm guessing when it's loading resources) and I get a nice crash dialog from my OS describing some low level stuff.
So my reason for posting is to gather some advice or guidance on how to tackle this. Is there a simple way to debug a program when it's in JAR form?
Any comments will be welcomed! Thanks.

Those links you posted proved very useful. Using OS dumps a log file which points out an offending library. After a bit of googling, I manage to found out that it was coming from the SWT framework which my app is built on. I've written tons of SWT apps before but I've no idea why this one get upset when I run it?
I've since took the time to compile and run a Windows & Linux version and they both work perfectly.
Thanks for the help on this and judging my current situation I think it would be best to speak to the Eclipse/SWT people as this problem has gone slightly 'off-topic' :)

Wifi works at home but not when away from home
My Wifi works at home but not when away from home, what is wrong? I thought with a phone plan I didn't need to have a wifi connection.
You either need WiFi or Cellular (or both). If you have neither, you can't connect to the internet.
Most people use WiFi at home and Cellular while away from home, or connect to public WiFi networks where there are some. -
CommandAction works through OnDeviceDebug, but not when installed from jar
Hi everybody,
I'm trying to run a HelloMIDlet example and if I run it on emulator it works fine, also when I run it on mobile through OnDeviceDebug from eclipse it works fine, but when I install a jar file and run the application it ends with Application Error message and it exits. I found out that the problem might be in the CommandAction method, because when I use this:
public void commandAction(Command c, Displayable s) {
notifyDestroyed();
}then the application works also when installed from jar, but when I use this:
public void commandAction(Command c, Displayable s) {
String label = new String("Exit"); //just for test
if (label.equals("Exit"))
notifyDestroyed();
}then it ends with Application Error right after I run the program (and it works when I use OnDeviceDebug). I'm using jdk1.5.0_06 and WTK from Sony Erricsson (my target device is W800i, which supports CLDC1.1 and MIDP2.0)
My manifest file is
Manifest-Version: 1.0
MicroEdition-Configuration: CLDC-1.1
MIDlet-Name: HelloMIDlet
Created-By: Sun Microsystems Inc.
MIDlet-Vendor: Sun Microsystems, Inc.
MIDlet-1: HelloMIDlet, , HelloMIDlet
MIDlet-Version: 1.0
MicroEdition-Profile: MIDP-2.0
MIDlet-Description: Hello Worldand I don't use the jad file when installing the application (seems to be unecessary when you have a manifest file inside the jar). And I'm unable to debug it because when debugging then it works normally. Also I tried to recompile the BluetoothDemo and the same error(and works through OnDeviceDebug). And when I installed the jar file, which is originally distributed with BluetoothDemo then it worked. When I compared original jar file and my jar file then the only difference was in the size the class files (class files compiled by me were bigger then the class files in original jar file (which work)).
Any ideas guys and girls?I tried that approach but it doesn't work either. I think maybe my directory structure is wrong.

UIImpersonator tests work in FlashBuilder, but not when run from Ant
I'm in the process of converting a Flex 3 project to use FlexUnit4 tests.
Everything compiles in Flashbuilder 4.5 and runs nicely. I've converted all the tests
to use flexunit 4, which highlighted a few issues, but nothing too major, and all the
tests now pass when run in Flashbuilder.
So... now, I'm trying to convert the CI build to use the 4.5 SDK and flexunit4. So far,
so good. Everything runs and I get a nicely formatted JUnit report. Unfortunately, though,
any test that uses the UIImpersonator fails with an async method timeout, suggesting that
the CreationComplete event hasn't fired.
Here's a typical example of one of my UI test cases:
[Test(async, ui)]
public function testAvailableProductsSetupAdminForSell() : void {
var view:OrderBasketView = new OrderBasketView();
var user:CfxUser = new CfxUser();
user.admin = true;
ModelLocator.instance.userDetails = user;
view.buyOrSell = OrderType.SELL;
helper.createComponentAndAddListener(view, this, availableProductSetupAdminForSellCreationComplete);
private function availableProductSetupAdminForSellCreationComplete(event:Event, view:OrderBasketView) : void {
Assert.assertTrue(view.availableProductTypes.contains(ProductType.PRODUCT_1));
Assert.assertTrue(view.availableProductTypes.contains(ProductType.PRODUCT_2));
Assert.assertTrue(view.availableProductTypes.contains(ProductType.PRODUCT_3));
and helper.createComponentAndAddListener looks like this:
public function createComponentAndAddListener(view:UIComponent, testCase:Object, creationComplete:Function) : void {
_view = view;
_view.addEventListener(FlexEvent.CREATION_COMPLETE, Async.asyncHandler(testCase, creationComplete, 4000, _view));
UIImpersonator.addChild(_view);
If I use FlexGlobals.topLevelApplication.parent.addChild(_view) in place of UIImpersonator.addChild(_view), all the tests pass.
I was wondering if it's a function of the fact that my helper class has no metadata that indicates it's a ui test, but that wouldn't explain why it works in FlashBuilder and not when run with ant.
I also wondered if it was a function of running with headless server set to true, but when I changed it to false the same thing happened.
My environment is:
ubuntu 11.04
ant 1.7.1
Sun jdk 1.6.0_26
Flex SDK 4.5.1.21328
FlexUnit 4.1.0-8-4.1.0.16076
I'm using the auto-generated TestRunner.mxml
Any thoughts, anyone? Now that I can get it to work by adding the UI components to the topLevelApplication, at least I can make progress, but I'd like to get to the bottom of the problem, because that shouldn't be necessary.
Thanks in advance,
-ChrislChanging to the topLevelApplication did not work. What's funny is that it then failed on a completely unrelated test by hanging and never returning... I'm thinking there must be something else that is going on here, but it's not clear what... :-/ Here is an example of my setup/teardown and a test that work great in the UI but not in CI...
[Before(async, ui)]
public function setUp():void
_fromToList = new FromToList();
_fromToList.setStyle('skinClass', FromToListSkin);
Async.proceedOnEvent(this, _fromToList, FlexEvent.CREATION_COMPLETE, 1000);
FlexGlobals.topLevelApplication.parent.addChild(_fromToList);
// UIImpersonator.addChild(_fromToList);
[After(ui)]
public function tearDown():void
FlexGlobals.topLevelApplication.parent.removeChild(_fromToList);
// UIImpersonator.removeChild(_fromToList);
_fromToList = null;
[Test(async)]
public function should_remove_selected_item_in_to_list_to_from_list():void
_fromToList.fromArrayList = _dpArray;
_fromToList.toArrayList = _toDpArray;
var sequence:SequenceRunner = new SequenceRunner(this);
sequence.addStep(new SequenceSetter(_fromToList.toList, { selectedItem: _toDpArray[1]}));
sequence.addStep(new SequenceWaiter(_fromToList.toList, FlexEvent.VALUE_COMMIT, 100));
sequence.addStep(new SequenceCaller(_fromToList, _fromToList.remove));
sequence.addStep(new SequenceWaiter(_fromToList, FromToListChangeEvent.FROM_TO_LIST_CHANGE_EVENT, 100));
sequence.addAssertHandler(handleListHasChangedThenRemoveEvent, {});
sequence.run();
private function handleListHasChangedThenRemoveEvent(event:FromToListChangeEvent, passThruData:Object):void
assertThat(_fromToList.toArrayList.length, equalTo(_toDpArray.length - 1));
assertThat(_fromToList.fromArrayList.length, equalTo(_dpArray.length - _toDpArray.length + 1));
assertTrue(_fromToList.fromArrayList.contains(_toDpArray[1]));
So you can see that I'm using Sequences to manage waiting for stuff to get updated in the background, and basically testing when I select an item in a list and act on it that it updates the model like I expect. Again, works GREAT in the UI Runner.
I'm open to suggestions... -
Applescript works in Automator, but not when app is opened - running all if statements at once?
Good evening,
I am new to applescript and have a newbie question regarding the following code. I am making a simple automator program to pull songs from iTunes to practice dancing to. I've started the program with a script that lets the user choose which dances (s)he wants to be played. Then I use applescript to run if statements for each dance, checking whether the dance was selected (and is therefore in "danceList"). If so, I call a separate app to handle finding and playing that dance. The whole thing runs perfectly once opened in automator.
The problem is when I try to open the app for the first time, whether in finder or in automator -- it calls every single one of the if-statement applications, all at once, before anything else has happened, and thus crashes itself. I have no idea why. I have searched various help sites, tried multiple variations of the if statement code (waltz is an example, below) and making the sub-applications into workflows, but that didn't help.
Any advice or pointers in the right direction/to appropriate resources would be greatly appreciated.
Here is a snippet from the relevant code: (didn't include it all, it's the same thing with more if statements)
on run {danceList}
if danceList is not null then
if danceList contains "Waltz" then
tell application "waltz"
run
end tell
delay 110
else
tell application "waltz"
quit
end tell
end if
if danceList contains "Tango" then
tell application "tango"
run
end tell
delay 110
end if
if danceList contains "Viennese Waltz" then
tell application "viennese"
run
end tell
delay 110
end if
... and so forth ...
end if
return danceList
end runOk, let me try to do a better job explaining.
I am making this app to simulate the rounds used in competitive ballroom dancing. It lets the user select the dances they will participate in, and then, for each dance, the program reads out the dance title, chooses all songs in iTunes with that genre, selects one at random, starts playing it, waits ninety seconds, and then stops the music. Then a twenty second pause before the next dance. I have made eleven apps for this; one is the main app that calls the others; the others are identical and handle the individual dances.
Here is all the code I have:
1. Ask for confirmation - dialogue box explaining app
2. Get specified text - list of all dances, passed to first section of applescript
3. First section of script - found on internet, altered for multiple selection; lets user choose multiple dances from a list (code is below pic)
on run {input, parameters}
choose item(s) from text
input: text - items are delimited by paragraphs (returns/newlines)
output: a list of paragraphs selected
set output to {}
set NameList to {}
set NameList to paragraphs of (input as text)
activate me
set TheChoice to (choose from list NameList with title "Choose Dances" with empty selection allowed and multiple selections allowed)
if TheChoice is false then
error number -128 -- cancel
else
set output to TheChoice
end if
return the output -- pass the result to the next action
end run
4. Store value of variable as "danceList" - probably unnecessary but gave it a name
5. Second section of applescript - what's been discussed previously, here's the full code:
on run {danceList}
if danceList is not "" then
if danceList contains "Waltz" then
tell application "waltz"
run
end tell
delay 110
end if
if danceList contains "Tango" then
tell application "tango"
run
end tell
delay 110
end if
if danceList contains "Viennese Waltz" then
tell application "viennese"
run
end tell
delay 110
end if
if danceList contains "Foxtrot" then
tell application "foxtrot"
run
end tell
delay 110
end if
if danceList contains "Quickstep" then
tell application "quickstep"
run
end tell
delay 110
end if
if danceList contains "Samba" then
tell application "samba"
run
end tell
delay 110
end if
if danceList contains "Cha cha" then
tell application "chacha"
run
end tell
delay 110
end if
if danceList contains "Rumba" then
tell application "rumba"
run
end tell
delay 110
end if
if danceList contains "Paso Doble" then
tell application "paso"
run
end tell
delay 110
end if
if danceList contains "Jive" then
tell application "jive"
run
end tell
delay 110
end if
end if
return danceList
end run
Here is the code for the waltz app. All the other dance apps are identical; they just search for different terms and have a different introduction spoken.
1. Get specified text - "Next Round is the Waltz, etc."
2. Speak text - reads text out loud so people know what's next
3. Find iTunes tracks where genre is "Waltz" or "waltz"
4. select these tracks
5. store all these in variable "tracks"
6. applescript to pick a random track from "tracks":
on run {tracks}
set maxNumber to count of tracks
set randy to random number from 1 to maxNumber
set chosenTrack to item randy of tracks
return chosenTrack
end run
7. 3 second pause between speech and music
8. Start playing the chosen track
9. 90 second wait while track plays
10. pause itunes (stop music)
11. end app
Again, my concern here is why the program runs fine once it has already been opened in automator (say second or third time running it there) but when run from finder, or first opened in automator, it calls all the dance apps at once. Then they give error messages because the speech section is first, and this can't be done simultaneously:
Also, not sure if this is relevant, but I have a spinning gear in the corner of my mac that I believe is automator launcher, and it's showing all the apps as running even after I've ok'd their error messages and they have disappeared from the dock. I can exit waltz and danceApp, which are the two actually running, but the others won't stop until I've ended automator launcher in activity monitor.
Hopefully this is more helpful. Thanks again. -
EncryptedLocalStore... works in debug, but not when compiled.
Okay, so I looked around the forum and saw a couple of people with this same problem, but their solutions didn't seem to help me. I don't know if it's because I didn't understand them, or what.
Here's my problem.
I've written a nifty little AIR app (AIR 1.5), using Aptana, JavaScript (jQuery) and HTML. The app works perfectly when run from the debugger inside of Aptana.
However, when I deploy the application (sign it with my self-signed certificate, etc.) and then install it, all of the ELS functionality ceases to work.
I'm obviously not the first person this has happened to, but I don't know what it is that I'm doing wrong.
If it helps, here is the code for my DataStoreManager:
var DataStoreManager = function(){
return{
__insert: function(key, data){
* function to insert data into the local encrypted datastore
* @author: Chris Jordan
* @date: 03/22/2010
* @param: key - the key to save the data to in the encrypted store.
* NOTE:
* This now relys on the global AppConfig object rather than any passed in values.
var my = {};
//serialize the AppConfig object
my.serializedAppConfig = jQuery.toJSON(data);
my.byteArray = new air.ByteArray();
my.byteArray.writeUTFBytes(my.serializedAppConfig);
air.EncryptedLocalStore.setItem(key, my.byteArray);
em.dispatchEvent("DataStorageComplete");
__read: function(key){
* function to read data from the local encrypted datastore
* @author: Chris Jordan
* @date: 03/23/2010
var my = {};
//get the byteArray back out of the encrypted local store
my.byteArray = air.EncryptedLocalStore.getItem(key);
if(my.byteArray != null){
//if we got something back, then read it and return it.
return my.byteArray.readUTFBytes(my.byteArray.bytesAvailable);
else{
return "";
__remove: function(key){
* function to remove data from the local encrypted datastore
* @author: Chris Jordan
* @date: 03/23/2010
air.EncryptedLocalStore.removeItem(key);
BTW, is there a better way to insert code snippets into a forum post? I just manually edited the html to make it a bit nicer to look at. Anyway, that aside, I'm hoping that someone can help me with my real issue.
Thanks!Okay, so I switched from using the ELS to just writing my serialized string out to a file. This didn't fix my problem though. The app still behaves the same way. Only now, I can monitor that file that I'm writing the serialized string to, for changes and I learned something by doing this.
My app has a config screen that gathers three pieces of information and stores it. So the user opens this screen, adds the data, and clicks save to write the data to a file, and close the window. So the end result of clicking save is that the config window closes (after having written the data to file).
When I export the app and run it, I add some data and click save, but the window doesn't close. I can, at that point look at the config file and see that the data has indeed been serialized and written to the file. It just appears that the screen hasn't closed. So, I click save again (what else am I going to do?). This time the window closes, but an empty string has been written out to the file replacing the config string I had out there to begin with!
So when I saw this behavior I immediately thought that maybe I had a timing issue. I should probably explain that I'm using jQuery (.bind and .trigger) to implement the observer pattern in this app. So, when I click the "Save" button, an event gets dispatched telling the app to write the data down to the disk. When that's done the function that is doing the writing announces that it's done saving, and in response to that announcement I dispatch two other events. One to close the config window, and one that rebuilds a menu using the new config data. These last two events should be mutually exclusive. They don't depend on each other. But just in case, I have tried just dispatching the close window event, and commenting out the rebuild menu event. That didn't help at all.
So, like I said, maybe I've got some kind of timing issue here. So I took my dispatchEvent function and wrapped it in a timer.
//the way my dispatchEvent function used to look (without the timer)
var em = function(){
return {
dispatchEvent: function(e, o){
jQuery(document).trigger(e,[ o || null ]);
//new and improved function with a timer...
var em = function(){
return {
dispatchEvent: function(e,o){
var my = {};
my.timeout = setTimeout(function(){
jQuery(document).trigger(e,[ o || null ]);
},100);
However, for all this... the timer didn't change things at all. I tried 100 milliseconds and 500 milliseconds. No difference. So, maybe it's not a timing issue... I don't know.
This is really bugging the crap out of me. I'm doing something wrong I guess, but I can't seem to figure out for the life of me, what the hell it is! Maybe I've just been staring at the code too much, but I could really use a hand. Has anyone else ever encountered this kind of thing before?
I'm starting to wonder what sort of apps have been written for the AIR platform using JavaScript. Is this happening because of the way I'm implementing the observer pattern or what? I know that last one would be difficult to answer without having all my code to look at, but I'm not beyond thinking that I've just done something wrong on that front.
BUT...
It works PERFECTLY when being run from within the IDE (again, that's Aptana in this case).
What gives?
Thanks for reading. I hope someone out there can help me. -
Workshop App Works on Admin but Not On Managed Server
Hi all, I have a very simple test Workshop App that works fine on an Admin server
but not on a Managed Server. I have all the JMS and JDBC resources that the apps
need, the console does not complain, they deploy fine, but for some reason I get
exceptions when deployed to the Managed server but works fine on the Admin server.
What's the difference between both servers? I start one with startWebLogic.cmd
and the other one with startManageWebLogic.cmd in the same domain directory. The
only resource that I have not been able to target to the managed server is WSStoreForwardInternalJMSServercgServer
which I have no idea what it is or if it matters. Some portions of the app works
when deployed to the managed server so I know it has deployed fine and some simple
pages compile and work fine but when using certain JAR files in the lib directory
I get weird exceptions on the managed server and not on the Admin server.
I'd appreciate any help.

Url links in swf work in standalone, but not when opened in browser
I am currently using flash to create an electronic press kit.
In that, i have 2 links to youtube (since embedding the videos was
not an option, making the file too large), and one link to
yousendit for the viewer to be able to download a pdf file.
Now when i open the swf by double clicking on it (which i can
do, but when on another computer, that has flash player installed,
the swf will not open unless opened through a browser....not sure
if that is just something where you can open an swf strictly by
itself only if you actually have flash or what....that is another
issue), but anyways, when i open the swf by itself, the links work
correctly. once opened through a browser, the links do not work.
Safari error:
Adobe flash player has stopped a potentially unsafe
operation.
The following local application of your computer or network:
(location of swf on harddisk)
is trying to communicate with this internet-enabled location:
youtube.com
To let this application communicate with the internet, click
SETTINGS.
You must restart this application after changing your
settings.
Of course i did that, and it didnt happen.
My question is however, even if this is a simple security
issue/setting within the browser, is there any way to get around
this? Because when sending this press kit out, the last thing i
want is for the viewer to have to take the time to change their
browser settings and try to get this to work and all that stuff.
Any help would be appreciated.
You can also download this swf at the following link:
http://www.yousendit.com/transfer.ph...661F585ACE0521The reason the swf doesn't open up by itself on other
computers is that it needs a Stand Alone Flash Player to do so.
Most people have the Flash plug-in for their browsers, but not the
stand alone player. If you are sending it out as a self contained
file you need to make a Projector file. It contains the SA + swf in
one file, which adds weight. Also, you need to make a Windows one
and and a Mac one. If you are using CS3, I think you can make a
Abobe AIR app that is universal, granted you install the free AIR
plug-in controlls for Flash ( I THINK. My knowlege is not totally
up to date) .
As for the links not working in the browser, its seems like
they should work. Your posted link for the file is broken, so
couldn't see. What is your code for the buttons? Are you calling
JavaScript in your html page? I've had problem with that usually a
syntax error or IE.

Vi works in LabVIEW, but not when executed by TestStand.
Hi everybody. I'm using LabVIEW 8 with the Sound and Vibration
Toolkit, and TestStand2. I am planning on using TestStand to
execute a series of performance tests on an audio processing
board. When run independently, the vi (which I have attached
here) runs correctly, and returns a value for the parameter being
tested. In this case it is SNR.
However, when executed by TestStand, the vi seems to run correctly, but
returns a value of "NaN". This causes TestStand to fail the test.
Does anybody know what is going on here? I've checked FAQs and
help files, etc... Why would the vi work on its own but not in
TestStand?
Thanks.

SingleChannelSNR.vi 173 KB
Test Sequence.seq 15 KBHi Ray, Thanks for the reply.
Basically, when I run the VI on its own, I see the SNR value appearing
both in the SNR indicator and in the Test Data Out cluster under
Numeric Measurement. The rest of the indicators are empty
(string, report text, status, code, source). My waveform graph
shows an FFT of the signal.
However, when running the exact same VI through TestStand, I get NaN as
the output. The FFT of the signal is NOT displayed in the
waveform graph... strange. No errors are received.
In order to make it easier to debug, I replaced all of the analysis functions
with functions included in LabVIEW 8. Now everybody should be
able to run it. I do a simple THD test this time around. With the VI running
on its own, I get a value of 1.8 as the THD and the Numeric Measurement of Test Data
Out. However, whenever running the test with TestStand, I get a
value of NaN.
Same problem.
Any suggestions?
By the way, what exactly do you mean by "wiring
up the Error cluster and feed in to the Error Out."? I'd
like to try it out, but I'm not sure exactly what you mean. I
already have the Error out cluster wired up, I think.

Works in RSA3 but not when pulling from BI
Hi,
I created a generic dataSource(Function Module) for Bill Of Material. When testing in RSA3 it is working fine. But when pulling data from BI with particular material in the Data Selection, it is saying "No data available". If I am pulling the same with no data selection then it is giving an error message "Job terminated in source system --> Request set to red".
When checked in SM37 I see the following error messages.
No active nametab exists for /SAPAPO/MATKEY DA 300
Job cancelled after system exception ERROR_MESSAGE
Can any body help me on this
Thanks for your help
SubraEvery thing is fine in all these transactions SM58, BD87, & WE05. There is no problem with the connections at all. I replicated many times and the error is always the same.
The error message below is the reason.
No active nametab exists for /SAPAPO/MATKEY
This messsage is not coming when testing in RSA3. Only when pulling the data from BI, this error is happening.
We are not using SAPAPO but still this message is coming up.
thanks

Dynamic Parameter List works on desktop but not when run on Crystal Server
Hi,
I have a report, and the database command query takes one parameter ({?Year}. There is a second parameter used for a record select which is a dynamic paramenter list (multiple select, required). When running the report from Crystal Reports 2008 on my desktop, it first prompts for a year, and then once that is entered, it will come back with the list (of Companies) to select from. It works very smootly and as desired.
But when I load this report to Crystal Reports 2008 Server, it will ask for the year (which is a static list), and this is good, but then it comes back with an empty dynamic select list on the next screen.
Are there any special caveats that I need to be aware of in regards to dynamic lists when running from the CR server?
Thanks!Hi Pat,
This should work but a couple of things to check:
1) Are the two parameters linked to the same database? If the parameters are linked to fields from different tables in different databases then you need to make sure you set the Database Configuration and have the report log on to both databases.
2) Are Crystal Reports and Crystal Server the same version? I had problems with parameters after we upgraded to 2008. We had to install the latest service packs for both Crystal 2008 and the Enterprise Server. Then we installed Crystal 2008 on the same machine the Enterprise Server was on. Crystal Reports and the Enterprise Server share some common files. Some of those files were updated for Crystal but not for the Enterprise Server yet. Once we synched them our reports have run fine.
Good luck,

HelpSet works but not when packaged in JAR
I have been using the JavaHelp and it all works perfectly if I just compile and run it from Eclpise, but when I try packaging everything into a JAR it doesn't work. Can anyone help me please?
public void loadHelpSet()
InfoMsg.postError("loading help") ;
try
// Get the classloader of this class.
ClassLoader cl = this.getClass().getClassLoader() ;
URL url = HelpSet.findHelpSet(cl, "Irs") ;
irsHS = new HelpSet(cl, url) ;
HelpBroker hb = irsHS.createHelpBroker() ;
hb.setDisplayed(true) ;
catch (Exception e)
InfoMsg.postError("Unable to load Help Set") ;
} // end loadHelpSet
it doesn't appear to get past the line irsHS = new HelpSet(cl, url) when run from the JAr, but it doesn't appear to throw an error either as no message box is shown (as it would if it couldn't find the helpset under normal circumstances when run from Eclipse)I tried that approach but it doesn't work either. I think maybe my directory structure is wrong.

Java sound app works on Mac but not on Windows
I am working on a program that needs to play a sound Clip and it doesn't work on XP but it does on OS/X.
I've reduced the problem to this simple test program. On my PC, the sound I hear on the speakers is just a little burst of noise, whereas it's fine on my Mac. I used one of XP's system wav files, and verified that it does play normally on the PC via other means (iTunes, etc.). I'm using the latest JDK/JRE everywhere. Here's the sample code. Anything obviously wrong here?
import java.io.*;
import javax.sound.sampled.*;
class ClipTest
public static void main(String args[])
try
Clip soundClip;
AudioInputStream soundStream;
File audioFile = new File("CHIMES.WAV");
soundStream = AudioSystem.getAudioInputStream(audioFile);
AudioFormat format = soundStream.getFormat();
DataLine.Info info = new DataLine.Info(Clip.class, format);
System.out.println(format.toString());
soundClip = (Clip)AudioSystem.getLine(info);
soundClip.open(soundStream);
soundClip.start();
catch (Exception e)
e.printStackTrace();
}Solved my own problem: adding a Thread.sleep(1000); after starting the Clip worked. Looks like the app was terminating before the sound could finish playing. Obviously something is different between the way the Mac and XP JRE handles the sound thread with respect to the rest of the app.

DB Link - works via SQL but not via packages
I have a database link on user ODB on database A, to database B. The DB Link seems fine for SQLs that i do, but doesn't compile in my package code. Please tell me why it works for "regular sqls" but not inside a package.
Example: while connected as ODB user on database A, if I do this query:
SELECT "TRAXDOC_DETAIL"."FILE_NAME",
"TRAXDOC_DETAIL"."FILE_TYPE",
FROM "TRAXDOC_DETAIL"@TRAXDOC_LINK
WHERE "TRAXDOC_DETAIL"."TRAXDOC_ROW_ID" = 100031 AND
"TRAXDOC_DETAIL"."TRAXDOC_LINE"= 2
It works fine. But the same query inside a package that is owned by user ODB on database A will not compile, stating the table/view does not exist.
The database link is owned by use ODB on database A, connects directly to the owner of the tables in question on database B.
Any suggestions welcome... this is an urgent issue, because it also worked fine on my customer's test environment, but not on their Production that they just upgraded. I need to know what to look for as to what could be wrong.Thanks so much for your response - Prefixing the call to the table within the package, with the schema owner does indeed solve the problem. Since this is a Production issue, i have implemented this fix in my customer's database.
However, I would still like this issue permanently resolved. The next time we send out updated package code, this will happen again (unless we then fix it again). I'd still like info from anyone on what exactly must be done to allow the call within the package to work without specifically pre-fixing the table's schema owner. It shouldn't be needed... The DB link is connecting via the same schema on database B that owns the table in question.
pre-fixing the schema owner is something we don't do in our sql statements, and this has worked fine for many of our cusomer's environments. We're only seeing this issue on one environment.
