Last cause: can't serialize class $Proxy23
My Wicket application uses Guice for DI and some AOP. I have successfully injected a DAO and used that to display records. However, when I try to save a new record in my form, I get the following exception Root cause: java.lang.IllegalArgumentException: can't serialize class $Proxy23 at org.bson.BasicBSONEncoder._putObjectField(BasicBSONEncoder.java:270) at org.bson.BasicBSONEncoder.putObject(BasicBSONEncoder.java:174) at org.bson.BasicBSONEncoder._putObjectField(BasicBSONEncoder.java:226) at org.bson.BasicBSONEncoder.putObject(BasicBSONEncoder.java:174) at org.bson.BasicBSONEncoder._putObjectField(BasicBSONEncoder.java:226) at org.bson.BasicBSONEncoder.putObject(BasicBSONEncoder.java:174) at org.bson.BasicBSONEncoder.putObject(BasicBSONEncoder.java:120) at com.mongodb.DefaultDBEncoder.writeObject(DefaultDBEncoder.java:27) at com.mongodb.OutMessage.putObject(OutMessage.java:289) at com.mongodb.DBApiLayer$MyCollection.insert(DBApiLayer.java:239) at com.mongodb.DBApiLayer$MyCollection.insert(DBApiLayer.java:204) at com.mongodb.DBCollection.insert(DBCollection.java:148) at com.mongodb.DBCollection.insert(DBCollection.java:91) at com.mongodb.DBCollection.save(DBCollection.java:810) at com.google.code.morphia.DatastoreImpl.save(DatastoreImpl.java:731) at com.google.code.morphia.DatastoreImpl.save(DatastoreImpl.java:793) at com.google.code.morphia.DatastoreImpl.save(DatastoreImpl.java:787) at com.hp.honeybadger.persistence.dao.morphia.MorphiaCnavUrlDAO.save(MorphiaCnavUrlDAO.java:50) at java.lang.reflect.Method.invoke(Method.java:601) at org.apache.wicket.proxy.LazyInitProxyFactory$JdkHandler.invoke(LazyInitProxyFactory.java:435) at $Proxy23.save(Unknown Source) at com.hp.honeybadger.console.forms.CnavForm$1.onSubmit(CnavForm.java:72) at org.apache.wicket.markup.html.form.Form.delegateSubmit(Form.java:1253) at org.apache.wicket.markup.html.form.Form.process(Form.java:925) at org.apache.wicket.markup.html.form.Form.onFormSubmitted(Form.java:771) at org.apache.wicket.markup.html.form.Form.onFormSubmitted(Form.java:704) at java.lang.reflect.Method.invoke(Method.java:601) at org.apache.wicket.RequestListenerInterface.internalInvoke(RequestListenerInterface.java:258) at org.apache.wicket.RequestListenerInterface.invoke(RequestListenerInterface.java:216) at org.apache.wicket.core.request.handler.ListenerInterfaceRequestHandler.invokeListener(ListenerInterfaceRequestHandler.java:240) at org.apache.wicket.core.request.handler.ListenerInterfaceRequestHandler.respond(ListenerInterfaceRequestHandler.java:226) at org.apache.wicket.request.cycle.RequestCycle$HandlerExecutor.respond(RequestCycle.java:854) at org.apache.wicket.request.RequestHandlerStack.execute(RequestHandlerStack.java:64) at org.apache.wicket.request.cycle.RequestCycle.execute(RequestCycle.java:254) at org.apache.wicket.request.cycle.RequestCycle.processRequest(RequestCycle.java:211) at org.apache.wicket.request.cycle.RequestCycle.processRequestAndDetach(RequestCycle.java:282) at org.apache.wicket.protocol.http.WicketFilter.processRequestCycle(WicketFilter.java:259) at org.apache.wicket.protocol.http.WicketFilter.processRequest(WicketFilter.java:201) at org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:282) at com.google.inject.servlet.FilterDefinition.doFilter(FilterDefinition.java:163) at com.google.inject.servlet.FilterChainInvocation.doFilter(FilterChainInvocation.java:58) at com.google.inject.servlet.ManagedFilterPipeline.dispatch(ManagedFilterPipeline.java:118) at com.google.inject.servlet.GuiceFilter.doFilter(GuiceFilter.java:113) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1332) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:477) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:119) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:524) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:227) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1031) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:406) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:186) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:965) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:117) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:111) at org.eclipse.jetty.server.Server.handle(Server.java:348) at org.eclipse.jetty.server.AbstractHttpConnection.handleRequest(AbstractHttpConnection.java:452) at

Re: Last cause: can't serialize class $Proxy23
Your DAO is declare in your form and you use it inside an inner method, so yes, wicket is going to serrialize it. I think you should use @SpringBean, instead of @inject. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Last-cause-can-t-serialize-class-Proxy23-tp4660352p4660358.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Last cause: can't serialize class $Proxy23
No, Wicket is not trying to serialize your DAO. The exception occurs in the action phase of the request handling. It looks like you've passed an object to MongoDB which has a reference to the @Injected DAO, or at least to the component that has the DAO. It's this MongoDB DefaultDBEncoder.writeObject thing that's serializing/encoding something it shouldn't. If it's not clear by inspection how the object being passed to save() holds a reference (e.g. by being an inner class) then set a breakpoint and the debugger should point to the offending reference.
