Class cast exception does not allow deploying --------------------------------------------- Key: JBDS-440 URL: https://jira.jboss.org/jira/browse/JBDS-440 Project: Developer Studio Issue Type: Bug Affects Versions: 1.1.0.GA Reporter: Jeronimo Ginzburg Assignee: Max Rydahl Andersen Fix For: 2.0.0.beta1 After deploying a seam application which has dependencies on other projects and external jars this error appears when asking starting, publishing, cleanning, etc.: Publishing failed Could not publish to the server. org.eclipse.wst.server.core.internal.ModuleFolder Could not publish to the server. org.eclipse.wst.server.core.internal.ModuleFolder And this is the error log: java.lang.ClassCastException: org.eclipse.wst.server.core.internal.ModuleFolder at org.eclipse.jst.j2ee.internal.deployables.J2EEFlexProjDeployable.members(J2EEFlexProjDeployable.java:203) at org.eclipse.wst.server.core.internal.ModulePublishInfo.fillCache(ModulePublishInfo.java:283) at org.eclipse.wst.server.core.internal.ModulePublishInfo.getDelta(ModulePublishInfo.java:333) at org.eclipse.wst.server.core.internal.ServerPublishInfo.getDelta(ServerPublishInfo.java:360) at org.eclipse.wst.server.core.internal.Server.getPublishedResourceDelta(Server.java:1057) at org.eclipse.wst.server.core.model.ServerBehaviourDelegate.getPublishedResourceDelta(ServerBehaviourDelegate.java:547) at org.eclipse.wst.server.core.model.ServerBehaviourDelegate.publish(ServerBehaviourDelegate.java:613) 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) After this error, the only way to start the jboss within the developer studio is removing the server and adding it again. But the error appears later again. This bug seems to be fixed in WTP 2.0.3: https://bugs.eclipse.org/bugs/show_bug.cgi?id=233196 Is it possible to upgrade WTP version?
