Re: ClassLoader (Serialization?) error
It is indeed a weird case. I haven't ever found this error on my development environment, so it is hard to debug, only happens when the application is running deployed. I have never saw it live, only in the application's logs. I even found one of these errors that doesn't even finish the package name (mypackage.MyClass): Will keep on investigating, thanks for all your tips :-) mypac%3C/a%3E%3C/h4%3E%20%20%20%20%3Cdiv%20id= 2010-03-15 20:38:58,507 ERROR ap18_s1_IX_II [[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'] org.apache.wicket.request.target.resource.SharedResourceRequestTarget 359167|RGCZLpMSQGtMyQvz53HrwSsxrS9cGrRJQGyp8dJNNz3xTpHv8QpW!-469065994! 1268681938...@192.168.131.143 - unable to lazily register shared resource %3C/a%3E%3C/h4%3E%20%20%20%20%3Cdiv%20id= java.lang.ClassNotFoundException: mypac%3C at weblogic.utils.classloaders.GenericClassLoader.findLocalClass(GenericClassLoader.java:289) at weblogic.utils.classloaders.GenericClassLoader.findClass(GenericClassLoader.java:262) at weblogic.utils.classloaders.ChangeAwareClassLoader.findClass(ChangeAwareClassLoader.java:54) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at weblogic.utils.classloaders.GenericClassLoader.loadClass(GenericClassLoader.java:161) at weblogic.utils.classloaders.ChangeAwareClassLoader.loadClass(ChangeAwareClassLoader.java:35) at org.apache.wicket.application.DefaultClassResolver.resolveClass(DefaultClassResolver.java:103) at org.apache.wicket.request.target.resource.SharedResourceRequestTarget.respond(SharedResourceRequestTarget.java:149) at org.apache.wicket.request.AbstractRequestCycleProcessor.respond(AbstractRequestCycleProcessor.java:104) at org.apache.wicket.RequestCycle.processEventsAndRespond(RequestCycle.java:1181) at org.apache.wicket.RequestCycle.step(RequestCycle.java:1252) at org.apache.wicket.RequestCycle.steps(RequestCycle.java:1353) at org.apache.wicket.RequestCycle.request(RequestCycle.java:493) at org.apache.wicket.protocol.http.WicketFilter.doGet(WicketFilter.java:355) at org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:200) at mypackage.MyFilter.doFilter(MyFilter.java:37) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:42) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:3242) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) at weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:2010) at weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:1916) at weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1366) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:209) at weblogic.work.ExecuteThread.run(ExecuteThread.java:181) 2010-03-15 20:38:58,507 ERROR ap18_s1_IX_II [[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'] org.apache.wicket.request.target.resource.SharedResourceRequestTarget 359167|RGCZLpMSQGtMyQvz53HrwSsxrS9cGrRJQGyp8dJNNz3xTpHv8QpW!-469065994! 1268681938...@192.168.131.143 - unable to lazily register shared resource net.gencat.accesnet.t%3C/a%3E%3C/h4%3E%20%20%20%20%3Cdiv%20id= java.lang.ClassNotFoundException: net.gencat.accesnet.t%3C at weblogic.utils.classloaders.GenericClassLoader.findLocalClass(GenericClassLoader.java:289) at weblogic.utils.classloaders.GenericClassLoader.findClass(GenericClassLoader.java:262) at weblogic.utils.classloaders.ChangeAwareClassLoader.findClass(ChangeAwareClassLoader.java:54) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at weblogic.utils.classloaders.GenericClassLoader.loadClass(GenericClassLoader.java:161) at weblogic.utils.classloaders.ChangeAwareClassLoader.loadClass(ChangeAwareClassLoader.java:35) at org.apache.wicket.application.DefaultClassResolver.resolveClass(DefaultClassResolver.java:103) at org.apache.wicket.request.target.resource.SharedResourceRequestTarget.respond(SharedResourceRequestTarget.java:149) at org.apache.wicket.request.AbstractRequestCycleProcessor.respond(AbstractRequestCycleProcessor.java:104) at org.apache.wicket.RequestCycle.processEventsAndRespond(RequestCycle.java:1181) at org.apache.wicket.RequestCycle.step(RequestCycle.java:1252) at org.apache.wicket.RequestCycle.steps(RequestCycle.java:1353) at org.apache.wicket.RequestCycle.request(RequestCycle.java:493) at org.apache.wicket.protocol.http.WicketFilter.doGet(WicketFilter.java:355) at org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:200) at

I agree it's not a classloader issue, the classloader is being given a cobbled class name, so it's not its fault it cannot load it.

Re: ClassLoader (Serialization?) error
I guess you use that panel somewhere on a page near a shared resource, maybe for an Image, have you tried debugging the rendering of that page? A side note, probably totally unrelated to your problem: having 'head' tags inside a wicket:panel will probably result in invalid html, you should consider using wicket:head instead (see: http://cwiki.apache.org/WICKET/wickets-xhtml-tags.html) cheers, Jonas On Mon, Mar 15, 2010 at 10:11 AM, Xavier López xavil...@gmail.com wrote: I agree it's not a classloader issue, the classloader is being given a cobbled class name, so it's not its fault it cannot load it.

Re: ClassLoader (Serialization?) error
Looks like a resource called 'mypackage.MyClass fi usuari -- /divdiv id' was requested - that's the output after urldecoding the string from your exception message. I guess somewhere in your webapp resource url's are output incorrectly, or someone actually entered that string as url in his browser. Maybe you're trying to output html comment inside html comments, where the 'inner' comments terminate the 'outer' comments early, and leave an extra -- behind. So, I guess you don't have a ClassLoader issue here, nor a Serialization issue. cheers, Jonas On Fri, Mar 12, 2010 at 12:16 PM, Xavier López xavil...@gmail.com wrote: Hi, From time to time I see the following error in my deployed application's log.

Re: ClassLoader (Serialization?) error
sounds like a classloading effect. Have a look to the classloader hierarchy Here is a good doc: http://download.oracle.com/docs/cd/E12840_01/wls/docs103/programming/classloading.html Especially this one : Resource Loading Order http://download.oracle.com/docs/cd/E12840_01/wls/docs103/programming/classloading.html#wp1097288 François Le 12 mars 2010 à 17:30, Igor Vaynberg a écrit : ive seen this once before on the list. also with weblogic i think. search the list. -igor On Fri, Mar 12, 2010 at 3:16 AM, Xavier López xavil...@gmail.com wrote: Hi, From time to time I see the following error in my deployed application's log.
