[JBoss Tools (users)] - "Error copying file" during publish (RHDS CR1, JBAS 4.2.2, S

by gcomnz

I'm getting the following error for each of the publishable files in an EAR-style project set when I publish: | eclipse.buildId=unknown | java.version=1.6.0_03 | java.vendor=Sun Microsystems Inc. | BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US | Command-line arguments: -os win32 -ws win32 -arch x86 | | Error | Mon Nov 19 11:59:58 MST 2007 | Error copying file: C:\jboss-4.2.2.GA\server\default\deploy\spades-ear.ear\spades-ejb.jar\META-INF\ejb-jar.xml to META-INF\ejb-jar.xml | | java.io.IOException: The system cannot find the path specified | at java.io.WinNTFileSystem.createFileExclusively(Native Method) | at java.io.File.checkAndCreate(Unknown Source) | at java.io.File.createTempFile(Unknown Source) | at org.jboss.ide.eclipse.as.core.server.xpl.PublishUtil.copyFile(PublishUtil.java:98) | at org.jboss.ide.eclipse.as.core.server.xpl.PublishUtil.copyFile(PublishUtil.java:450) | at org.jboss.ide.eclipse.as.core.server.xpl.PublishUtil.copy(PublishUtil.java:505) | at org.jboss.ide.eclipse.as.core.server.xpl.PublishUtil.publishFull(PublishUtil.java:481) | at org.jboss.ide.eclipse.as.core.server.xpl.PublishUtil.copy(PublishUtil.java:496) | at org.jboss.ide.eclipse.as.core.server.xpl.PublishUtil.publishFull(PublishUtil.java:481) | at org.jboss.ide.eclipse.as.core.publishers.JstPublisher.fullPublish(JstPublisher.java:129) | at org.jboss.ide.eclipse.as.core.publishers.JstPublisher.publishModule(JstPublisher.java:111) | at org.jboss.ide.eclipse.as.core.server.internal.DeployableServerBehavior.publishModule(DeployableServerBehavior.java:130) | at org.eclipse.wst.server.core.model.ServerBehaviourDelegate.publishModule(ServerBehaviourDelegate.java:749) | at org.eclipse.wst.server.core.model.ServerBehaviourDelegate.publishModules(ServerBehaviourDelegate.java:835) | at org.eclipse.wst.server.core.model.ServerBehaviourDelegate.publish(ServerBehaviourDelegate.java:669) | at org.eclipse.wst.server.core.internal.Server.doPublish(Server.java:887) | at org.eclipse.wst.server.core.internal.Server.publish(Server.java:874) | at org.eclipse.wst.server.core.internal.PublishServerJob.run(PublishServerJob.java:72) | at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) | | Besides that error for each file, Eclipse doesn't seem to report any other errors. I'm using the Red Hat Developer Studio CR1 install. The project is vanilla, create by the Seam tool within Eclipse. I have plenty of disk space. The projects deployed properly at first, I then imported them into a fresh Eclipse workspace directory, and as near as I can tell that was when this started. I don't have the old workspace around to try moving them back. I have now tried creating a fresh project and am getting exactly the same result. I can't think of any other change of any significance that I have made to my system. Any ideas will be greatly appreciated?

[Messaging, JMS & JBossMQ] - Re: How to enlist JMS in stateless session bean container ma

by jhowell＠redhat.com

The answer that Adrian was referring to use the JCA adapter, which provides automatic transaction enlistment. Given that your SLSB method is transactional, all of the messaged queued in that method will be in the same transaction. Here's the link... http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossJMSRA Jay:) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4106144#4106144 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4106144

[JBoss Seam] - Re: JBoss tools - Seam generate entities from existing entit

by max.andersen＠jboss.com

JBoss Tools -> JBoss Tools forum (easy, right ;) "How can I get the "Seam Generate Entities" function working in eclipse without regnerating the entities?" For now you can remove the hbm2java from the generated code generation launch and just rerun it. For getting that more permantly in there report an issue in jboss tools. It is *related* to JBSEAM-843 but we don't use the ant tasks in jboss tools so this is not the same.

[JBoss Seam] - pagination and dataTable

by minamti

Is there an example of pagination with data table. I have seen posts that say that having an EntityQuery or a class that extends EntityQuery gives you pagination. Are there any examples of that ?

by dpabhay

Adrian, Could you please poste the URL where a resolution to the problem reported by David is detailed? I am having same problem - Do not want to send any message until all the messages have been queued, but cannot control that because if I createSession using "true" flag, none of the messages are delivered, whereas if "false" is used, messages are delivered and some are processed before the queueing is complete.

[JBoss Seam] - Re: Dynamic widgets?

by whafrog

We already have other applications deployed using 4.2.0, but this will be our first Seam app, so probably best to upgrade that now. Thanks for your help!
