The following situation happened when I switched from maven-bundle-plugin 1.4.0 to 2.3.4. I'm using the http://www.jidesoft.com Jide Product and they have a jar with their Synthetica UI delegates. As far as packages are concerned, this jar contains these two: - com.jidesoft.plat.synthetica - javax.swing.plat.synth Those familiar with Synthetica noticed that the package "javax.swing.plat.synth" is already part of the JDK (in rt.jar). There is only one class in their package. They say that until JDK7 they need to do this because they need access to certain methods not yet visible. I added this jar to my pom.xml dependencies (runtime scope) and when I started felix (v3.0.8), I got a NoClassDefFound on the class SynthLookAndFeel. java.lang.reflect.InvocationTargetException at java.awt.EventQueue.invokeAndWait(EventQueue.java:1042) at javax.swing.SwingUtilities.invokeAndWait(SwingUtilities.java:1326) {...} Caused by: java.lang.NoClassDefFoundError: javax/swing/plaf/synth/SynthLookAndFeel at com.jidesoft.plaf.basic.BasicJideButtonUI.updateMargin(Unknown Source) at com.jidesoft.plaf.basic.BasicJideButtonUI.installDefaults(Unknown Source) at com.jidesoft.plaf.basic.BasicJideButtonUI.installUI(Unknown Source) at javax.swing.JComponent.setUI(JComponent.java:662) at com.jidesoft.swing.JideButton.updateUI(Unknown Source) at com.jidesoft.plaf.basic.BasicCommandBarTitleBarUI$a_.updateUI(Unknown Source) at javax.swing.AbstractButton.init(AbstractButton.java:2149) at javax.swing.JButton.<init>(JButton.java:118) at javax.swing.JButton.<init>(JButton.java:73) at com.jidesoft.swing.JideButton.<init>(Unknown Source) at com.jidesoft.swing.JideButton.<init>(Unknown Source) at com.jidesoft.plaf.basic.BasicCommandBarTitleBarUI$a_.<init>(Unknown Source) at com.jidesoft.plaf.basic.BasicCommandBarTitleBarUI.installComponents(Unknown Source) at com.jidesoft.plaf.basic.BasicCommandBarTitleBarUI.installUI(Unknown Source) at javax.swing.JComponent.setUI(JComponent.java:662) at javax.swing.JMenuBar.setUI(JMenuBar.java:118) at com.jidesoft.action.CommandBarTitleBar.setUI(Unknown Source) at com.jidesoft.action.CommandBarTitleBar.updateUI(Unknown Source) at javax.swing.JMenuBar.<init>(JMenuBar.java:95) at com.jidesoft.action.CommandBarTitleBar.<init>(Unknown Source) at com.jidesoft.plaf.basic.BasicCommandBarUI.installComponents(Unknown Source) at com.jidesoft.plaf.basic.BasicCommandBarUI.installUI(Unknown Source) at javax.swing.JComponent.setUI(JComponent.java:662) at com.jidesoft.action.CommandBar.updateUI(Unknown Source) at javax.swing.JMenuBar.<init>(JMenuBar.java:95) at com.jidesoft.action.DockableBar.<init>(Unknown Source) at com.jidesoft.action.CommandBar.<init>(Unknown Source) at com.jidesoft.action.CommandBar.<init>(Unknown Source) at com.jidesoft.action.CommandMenuBar.<init>(Unknown Source) {...} Caused by: java.lang.ClassNotFoundException: javax.swing.plaf.synth.SynthLookAndFeel not found by myBundle [13] at org.apache.felix.framework.ModuleImpl.findClassOrResourceByDelegation(ModuleImpl.java:787) at org.apache.felix.framework.ModuleImpl.access$400(ModuleImpl.java:71) at org.apache.felix.framework.ModuleImpl$ModuleClassLoader.loadClass(ModuleImpl.java:1768) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 51 more For my felix to start, I now need to set the boot delegation (in config.properties) as: org.osgi.framework.bootdelegation=javax.swing.plaf.*,sun.*,com.sun.* Here's my maven-bundle-plugin configuration (if relevent): <plugin> <groupId>org.apache.felix</groupId> <artifactId>maven-bundle-plugin</artifactId> <extensions>true</extensions> <configuration> <instructions> <Bundle-Name>...</Bundle-Name> <Bundle-Version>${project.version}</Bundle-Version> <Private-Package>mypackage.osgi</Private-Package> <_exportcontents> com.jidesoft.*, net.miginfocom.*, org.apache.commons.logging.*, org.apache.poi.* </_exportcontents> <Import-Package>*;resolution:=optional</Import-Package> <Embed-Dependency>*;scope=compile|runtime;inline=false</Embed-Dependency> <Embed-Transitive>true</Embed-Transitive> <Service-Component>OSGI-INF/service-component.xml</Service-Component> <Include-Resource>{maven-resources}</Include-Resource> <Bundle-NativeCode> ... </Bundle-NativeCode> <Bundle-SymbolicName>${project.groupId}.${project.artifactId}</Bundle-SymbolicName> <Implementation-Vendor>...</Implementation-Vendor> <Implementation-Version>${project.version}</Implementation-Version> </instructions> </configuration> </plugin> I don't fully understand neither the problem nor the solution. Shouldn't class loaders "communicate" until the desired class is found? Is this the correct solution? Just so you know, in the bundle activator, I set the Swing classloader to my OSGi classloader with UIManager.put("ClassLoader", bundleContext.getClass().getClassLoader()); Regards ----- Tell me something you don't know! -- View this message in context: http://old.nabble.com/%22SynthLookAndFeel%22-NoClassDefFound-tp32011741p32011741.html Sent from the Apache Felix - Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
