I installed the module "Derby Database Support" on my German Windows machine. When I try to start the Derby database server or create a new database from the "Tools/Derby Database" menu i get the following message: java.lang.NoClassDefFoundError: und Exception in thread "main" and the following entry in the Netbeans log file [WinSys.PersistenceManager.getTopComponentForID] Problem when deserializing TopComponent for tcID:'navigator'. Reason: org.netbeans.modules.navigator.Navigator INFORMATIONAL *********** Exception occurred ************ at 4:04 PM on Aug 28, 2005 java.lang.ClassNotFoundException: org.netbeans.modules.navigator.Navigator at org.netbeans.ProxyClassLoader.loadClass(ProxyClassLoader.java:154) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at org.netbeans.modules.settings.convertors.XMLSettingsSupport$SettingsRecognizer.loadClass(XMLSettingsSupport.java:669) at org.netbeans.modules.settings.convertors.XMLSettingsSupport$SettingsRecognizer.createFromMethod(XMLSettingsSupport.java:621) at org.netbeans.modules.settings.convertors.XMLSettingsSupport$SettingsRecognizer.instanceCreate(XMLSettingsSupport.java:547) at org.netbeans.modules.settings.convertors.SerialDataConvertor$SettingsInstance.instanceCreate(SerialDataConvertor.java:357) [catch] at org.netbeans.core.windows.persistence.PersistenceManager.getTopComponentPersistentForID(PersistenceManager.java:428) at org.netbeans.core.windows.persistence.PersistenceManager.getTopComponentForID(PersistenceManager.java:535) at org.netbeans.core.windows.PersistenceHandler.getTopComponentForID(PersistenceHandler.java:352) at org.netbeans.core.windows.PersistenceHandler.initModeFromConfig(PersistenceHandler.java:319) at org.netbeans.core.windows.PersistenceHandler.load(PersistenceHandler.java:152) at org.netbeans.core.windows.WindowSystemImpl.load(WindowSystemImpl.java:39) at org.netbeans.core.NonGui$3.run(NonGui.java:218) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEvent(EventQueue.java:461) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:242) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:163) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:157) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:149) at java.awt.EventDispatchThread.run(EventDispatchThread.java:110) My Netbeans user directory is located at "C:\Dokumente und Einstellungen\holger\.netbeans\dev" I have once received the same exception message ("java.lang.NoClassDefFoundError: und") with an earlier version fo Ant. There the whitespace in the file path in my home directory (before "und") also caused the exception.
Reassigning from IDE issues, please evaluate.
Looks like a duplicate of issue 65050, that was already fixed by Andrei. Andrei, can you confirm?
Right, it's a duplicate. To reporter: it would be nice if you could try if the second JAR attached to issue 65050 solves the problem. *** This issue has been marked as a duplicate of 65050 ***
The JAR file you mention indeed solves the problem.
