[news.eclipse.newcomer] env debugging

prokashs@xxxxxxx (Prokash ) — Fri, 03 Jul 2009 23:52:27 GMT

Hi,

I'm new to both Java and Eclipse IDE. Here is a simple code, that i wanted to run thru debugger... package hello;

public class HelloWorld {
	
	public static void main(java.lang.String[] argv)
	{
		for ( int i=0; i < argv.length; i++)
		{
			java.lang.System.out.print("Hello " + argv[i])	;
			if (argv[i].equals("World"))
				java.lang.System.out.print('!');
			
			java.lang.System.out.print('\n');
			
		}
	}

Under the debug setting I've 3 blank separated string that should populate argv. when I run without debugger it is fine. But with debugger I get exceptions and others like

java.lang.OutOfMemoryError: Java heap space at java.util.ArrayList.(ArrayList.java:132) at org.eclipse.jdi.internal.ArrayReferenceImpl.readObjectSequence(ArrayReferenceImpl.java:162) at org.eclipse.jdi.internal.ArrayReferenceImpl.getValues(ArrayReferenceImpl.java:132) at org.eclipse.jdi.internal.ArrayReferenceImpl.getValue(ArrayReferenceImpl.java:65) at org.eclipse.jdt.internal.debug.core.model.JDIArrayEntryVariable.retrieveValue(JDIArrayEntryVariable.java:80) at org.eclipse.jdt.internal.debug.core.model.JDIVariable.getCurrentValue(JDIVariable.java:66) at org.eclipse.jdt.internal.debug.core.model.JDIVariable.getValue(JDIVariable.java:88) at org.eclipse.debug.internal.ui.model.elements.VariableLabelProvider.getLabel(VariableLabelProvider.java:91) at org.eclipse.jdt.internal.debug.ui.variables.JavaVariableLabelProvider.getLabel(JavaVariableLabelProvider.java:152) at org.eclipse.debug.internal.ui.model.elements.ElementLabelProvider.retrieveLabel(ElementLabelProvider.java:212) at org.eclipse.jdt.internal.debug.ui.variables.JavaVariableLabelProvider.retrieveLabel(JavaVariableLabelProvider.java:129) at org.eclipse.debug.internal.ui.model.elements.ElementLabelProvider$LabelUpdater.run(ElementLabelProvider.java:157) at org.eclipse.debug.internal.ui.model.elements.ElementLabelProvider$LabelJob.run(ElementLabelProvider.java:71) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

[news.eclipse.newcomer] orphaned connector

cmcdonough@xxxxxxx ( cam) — Fri, 03 Jul 2009 19:14:03 GMT

Hi I've imported a war file which contains several projects, 3 calldesign.xml files and 2 calldesign.frag.

I can open every file except one of the calldesign.frag files. I get an orphaned connector error.

Any idea what this could be? I've checked out this news group and did some googling to no avail.

Here's the full Exception:

java.lang.RuntimeException: orphaned connector: id=d13df3d457844dbaaac5b85966a47601 origin=c0e75e56c8804d559666f7a953d839a6 destination=aae216cd474b45c99cdfdd63b1fb0ad7 at org.eclipse.vtp.desktop.model.core.Connector.(Connector.java:53) at org.eclipse.vtp.desktop.model.core.Model.(Model.java:102) at org.eclipse.vtp.desktop.editors.core.impl.ApplicationFragmentEditor.init(ApplicationFragmentEditor.java:198) at org.eclipse.ui.internal.EditorManager.createSite(EditorManager.java:794) at org.eclipse.ui.internal.EditorReference.createPartHelper(EditorReference.java:643) at org.eclipse.ui.internal.EditorReference.createPart(EditorReference.java:426) at org.eclipse.ui.internal.WorkbenchPartReference.getPart(WorkbenchPartReference.java:592) at org.eclipse.ui.internal.EditorAreaHelper.setVisibleEditor(EditorAreaHelper.java:263) at org.eclipse.ui.internal.EditorManager.setVisibleEditor(EditorManager.java:1405) at org.eclipse.ui.internal.EditorManager$5.runWithException(EditorManager.java:939) at org.eclipse.ui.internal.StartupThreading$StartupRunnable.run(StartupThreading.java:31) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:129) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3659) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3296) at org.eclipse.ui.application.WorkbenchAdvisor.openWindows(WorkbenchAdvisor.java:801) at org.eclipse.ui.internal.Workbench$25.runWithException(Workbench.java:1342) at org.eclipse.ui.internal.StartupThreading$StartupRunnable.run(StartupThreading.java:31) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:129) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3659) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3296) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2309) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2219) at org.eclipse.ui.internal.Workbench$4.run(Workbench.java:466) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:289) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:461) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:106) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:169) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:106) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:76) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:363) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:176) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:508) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:447) at org.eclipse.equinox.launcher.Main.run(Main.java:1173)

Hello,
I have created a custom launch configuration, and am looking for a way to change the default 'New_configuration' to a more meaningful string.

I have made some progress with this, but fear I am heading down the path to ugly code. Here is what I have tried so far:

1) Looked at ILaunchConfiguration and noticed there is only a getName(), but no setName().

2) Looked at the eclipse source to find where the default name gets set, and found RunDebugPropertiesPage.java. Great to know, but this doesn't help me out much.

3) Figured out a way to access the text control that contains the launch configuration name. Then added a VerifyEvent to that text box. Here I can substitute my name in, which then shows up in the GUI. The problem is I can't save my working configuration, as I have no access to it in the VerifyEvent.

Looking for some guidance, hoping there is an easier way to do this.

I'm not sure how you arrived at the RunDebugPropertiesPage, but I don't think that is related (that appears to be a Preferences page, not part of the Launch Configuration dialog where these things are actually created). I would start by looking at the class org.eclipse.debug.internal.ui.launchConfigurations.CreateLaunchConfigurationAction which is what is invoked when the user presses the "New launch configuration" button in the dialog. (I used Plug-in Spy Alt+Shift+F1) to learn about the classes that implement that dialog).

Another avenue to explore would be to look at how other code does it; for example, if you select a class with a main() method, right-click, and select Run As > Java Application, it will create a launch configuration with a reasonable name. You can use the Plug-in Spy on Menus (Alt+Shift+F2) to learn what code implements that menu action.

Hope this helps,
Eric

[news.eclipse.newcomer] OSGi Drools integration

flavius@xxxxxxx (Flavius Vespasianus) — Fri, 03 Jul 2009 11:31:30 GMT

I am writing a plugin for Eclipse using Drools. I have tried to use SpringSource version of Drools (OSGi-compliant) but with little success.

I have downloaded and installed following plugins:

com.springsource.com.thoughtworks.xstream-1.3.0.jar
com.springsource.javax.rules-1.1.0.jar
com.springsource.javax.xml.stream-1.0.1.jar
com.springsource.jxl-2.6.6.jar
com.springsource.org.apache.jasper.org.eclipse.jdt-6.0.16.jar
com.springsource.org.codehaus.janino-2.5.15.jar
com.springsource.org.drools.compiler-4.0.7.jar
com.springsource.org.drools.decisiontable-4.0.7.jar
com.springsource.org.drools.jsr94-4.0.7.jar
com.springsource.org.drools-4.0.7.jar
com.springsource.org.mvel-1.3.5.jar
com.springsource.org.xmlpull-1.1.3.4-O.jar
com.springsource.org.xmlpull-1.1.4.jar

But when I try to run it using Eclipse Europa (Windows), it still says:

Bundle update@plugins/com.springsource.org.drools.compiler-4.0.7.jar was not resolved. Missing imported package org.eclipse.jdt.internal.compiler.classfmt_[3.2.3,4.0.0). Missing imported package org.eclipse.jdt.core.compiler_[3.2.3,4.0.0). Missing imported package org.eclipse.jdt.internal.compiler.problem_[3.2.3,4.0.0). Missing imported package org.eclipse.jdt.internal.compiler.env_[3.2.3,4.0.0). Missing imported package org.eclipse.jdt.internal.compiler_[3.2.3,4.0.0).

That's weird - the packages are in org.eclipse.jdt.core plugin and I have the version 3.3.3, so it should find it. I have tried it also with version 3.2.3 and 3.4.2 but no success. The target platform should be configured correctly, even when I try to use two versions at the same moment it complains.

I am desperate with that. Could you give me some clue why this isn't working?

Thanks a lot

Flavius

mbisme@xxxxxxx (MBisME ) — Fri, 03 Jul 2009 08:52:05 GMT

ok, im just posting this to let you know that i have fixed the issue.

the problem was the path, the full path that i was using was: D:\[Apps]\eclipse

i moved it to D:\eclipse and it works fine now. kinda weird though i think. but if anyone else has a problem with this then they can try to move it somewhere else and see if it works...
