Build Identifier: I20110613-1736 The imported package list in jetty's manifest file limits the version of javax.servlet to 2.5 or 2.6. The other dependent files of org.mortbay can load javax.servlet version of 3.x which leads to problems in the User Assistance area like this stacktrace: !ENTRY org.eclipse.ui 4 0 2011-11-01 11:15:18.633 !MESSAGE Unhandled event loop exception !STACK 0 java.lang.NoClassDefFoundError: org/eclipse/equinox/http/jetty/JettyConfigurator at org.eclipse.help.internal.server.JettyHelpServer $StartServerThread.run(JettyHelpServer.java:75) Caused by: java.lang.ClassNotFoundException: org.eclipse.equinox.http.jetty.JettyConfigurator at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal (BundleLoader.java:513) at org.eclipse.osgi.internal.loader.BundleLoader.findClass (BundleLoader.java:429) at org.eclipse.osgi.internal.loader.BundleLoader.findClass (BundleLoader.java:417) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass (DefaultClassLoader.java:107) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 1 more !ENTRY org.eclipse.help 4 0 2011-11-01 11:15:53.999 !MESSAGE Required attribute "id" missing from "context" element in "/com.sybase.sup.doc.contexts/contexts.xml" (skipping element) !ENTRY com.sybase.stf.sysam 1 10004 2011-11-01 11:19:47.325 !MESSAGE INFO: [msgId: 131257], message: Checked in license for 1 SWS_MOBL (2.0/permanent/0ADA A1F8 3A86 8354). !ENTRY org.eclipse.help.base 4 0 2011-11-01 11:19:47.919 !MESSAGE FrameworkEvent ERROR !STACK 0 org.osgi.framework.BundleException: Exception in org.eclipse.help.internal.base.HelpBasePlugin.stop() of bundle org.eclipse.help.base. at org.eclipse.osgi.framework.internal.core.BundleContextImpl.stop (BundleContextImpl.java:791) at org.eclipse.osgi.framework.internal.core.BundleHost.stopWorker (BundleHost.java:510) at org.eclipse.osgi.framework.internal.core.AbstractBundle.suspend (AbstractBundle.java:565) at org.eclipse.osgi.framework.internal.core.Framework.suspendBundle (Framework.java:1160) at org.eclipse.osgi.framework.internal.core.StartLevelManager.decFWSL (StartLevelManager.java:595) at org.eclipse.osgi.framework.internal.core.StartLevelManager.doSetStartLevel (StartLevelManager.java:257) at org.eclipse.osgi.framework.internal.core.StartLevelManager.shutdown (StartLevelManager.java:215) at org.eclipse.osgi.framework.internal.core.InternalSystemBundle.suspend (InternalSystemBundle.java:284) at org.eclipse.osgi.framework.internal.core.Framework.shutdown (Framework.java:690) at org.eclipse.osgi.framework.internal.core.Framework.close (Framework.java:597) at org.eclipse.core.runtime.adaptor.EclipseStarter.shutdown (EclipseStarter.java:390) at org.eclipse.core.runtime.adaptor.EclipseStarter.run (EclipseStarter.java:198) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework (Main.java:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) at org.eclipse.equinox.launcher.Main.main(Main.java:1386) Caused by: java.lang.NoClassDefFoundError: org/eclipse/equinox/http/jetty/JettyConfigurator at org.eclipse.help.internal.server.JettyHelpServer $StopServerThread.run(JettyHelpServer.java:93) Caused by: java.lang.ClassNotFoundException: org.eclipse.equinox.http.jetty.JettyConfigurator at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal (BundleLoader.java:513) at org.eclipse.osgi.internal.loader.BundleLoader.findClass (BundleLoader.java:429) at org.eclipse.osgi.internal.loader.BundleLoader.findClass (BundleLoader.java:417) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass (DefaultClassLoader.java:107) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 1 more Root exception: java.lang.NoClassDefFoundError: org/eclipse/equinox/http/jetty/JettyConfigurator at org.eclipse.help.internal.server.JettyHelpServer $StopServerThread.run(JettyHelpServer.java:93) Caused by: java.lang.ClassNotFoundException: org.eclipse.equinox.http.jetty.JettyConfigurator at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal (BundleLoader.java:513) at org.eclipse.osgi.internal.loader.BundleLoader.findClass (BundleLoader.java:429) at org.eclipse.osgi.internal.loader.BundleLoader.findClass (BundleLoader.java:417) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass (DefaultClassLoader.java:107) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 1 more Plugin dependencies of org.eclipse.equinox.http.jetty show the different javax.servlet versions used are 2.5 and 3.0.

We cannot tolerate servlet 3.0 until we have support for jetty 8. *** This bug has been marked as a duplicate of bug 309529 ***
(In reply to comment #2) > We cannot tolerate servlet 3.0 until we have support for jetty 8. > > *** This bug has been marked as a duplicate of bug 309529 *** Thanks Thomas, is there an ETA for this? Would it be possible to change the dependencies so that none of plugins jetty depends on (mortbay, etc) would use servlet version 3.0? The way it is now means that jetty (and the help system) is unusable, right?
Removing the plugin javax.servlet_3.0.0.v201103241727.jar solves the problem. I do not know who installed it. But plugin dependencies should be stricter to avoid problems like this one.
