Is the object you're trying to save onto the session serializable? Does it implement serializable? (although just making the class implement serializable will not always work)
I believe that you can have a class bypass validation for this when running locally - so you may not be seeing the serialization error because of this. In any case, I would definitely make sure you can actually serialize the object that you're saving. -Chris On Jan 5, 7:41 am, avdhesh <[email protected]> wrote: > I got following exception wehn i deploy a application to google apps > engine....Everything works fine with EclipsePlugin...May be > EclipsePlugin not able to catch this.. > > I filed a Bug report... > > http://code.google.com/p/googleappengine/issues/detail?id=2606 > > java.lang.RuntimeException: java.io.NotSerializableException: > com.google.apphosting.utils.jetty.AppEngineWebAppContext > $AppEngineServletContext > at > com.google.apphosting.runtime.jetty.SessionManager.serialize > (SessionManager.java:361) > at > com.google.apphosting.runtime.jetty.SessionManager.createEntityForSession > (SessionManager.java:341) > at > com.google.apphosting.runtime.jetty.SessionManager > $AppEngineSession.save(SessionManager.java:162) > at > com.google.apphosting.runtime.jetty.SaveSessionFilter.doFilter > (SaveSessionFilter.java:41) > at > org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter > (ServletHandler.java:1084) > at > com.google.apphosting.utils.servlet.TransactionCleanupFilter.doFilter > (TransactionCleanupFilter.java:43) > at > org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter > (ServletHandler.java:1084) > at org.mortbay.jetty.servlet.ServletHandler.handle > (ServletHandler.java:360) > at org.mortbay.jetty.security.SecurityHandler.handle > (SecurityHandler.java:216) > at org.mortbay.jetty.servlet.SessionHandler.handle > (SessionHandler.java:181) > at org.mortbay.jetty.handler.ContextHandler.handle > (ContextHandler.java:712) > at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java: > 405) > at > com.google.apphosting.runtime.jetty.AppVersionHandlerMap.handle > (AppVersionHandlerMap.java:238) > at org.mortbay.jetty.handler.HandlerWrapper.handle > (HandlerWrapper.java:139) > at org.mortbay.jetty.Server.handle(Server.java:313) > at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java: > 506) > at > org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete > (HttpConnection.java:830) > at > com.google.apphosting.runtime.jetty.RpcRequestParser.parseAvailable > (RpcRequestParser.java:76) > at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:381) > at > com.google.apphosting.runtime.jetty.JettyServletEngineAdapter.serviceReques t > (JettyServletEngineAdapter.java:135) > at > com.google.apphosting.runtime.JavaRuntime.handleRequest > (JavaRuntime.java:235) > at > com.google.apphosting.base.RuntimePb$EvaluationRuntime > $6.handleBlockingRequest(RuntimePb.java:5235) > at > com.google.apphosting.base.RuntimePb$EvaluationRuntime > $6.handleBlockingRequest(RuntimePb.java:5233) > at > com.google.net.rpc.impl.BlockingApplicationHandler.handleRequest > (BlockingApplicationHandler.java:24) > at com.google.net.rpc.impl.RpcUtil.runRpcInApplication(RpcUtil.java: > 363) > at com.google.net.rpc.impl.Server$2.run(Server.java:838) > at > com.google.tracing.LocalTraceSpanRunnable.run > (LocalTraceSpanRunnable.java:56) > at > com.google.tracing.LocalTraceSpanBuilder.internalContinueSpan > (LocalTraceSpanBuilder.java:536) > at com.google.net.rpc.impl.Server.startRpc(Server.java:793) > at com.google.net.rpc.impl.Server.processRequest(Server.java:368) > at > com.google.net.rpc.impl.ServerConnection.messageReceived > (ServerConnection.java:448) > at com.google.net.rpc.impl.RpcConnection.parseMessages > (RpcConnection.java:319) > at com.google.net.rpc.impl.RpcConnection.dataReceived > (RpcConnection.java:290) > at com.google.net.async.Connection.handleReadEvent(Connection.java: > 466) > at > com.google.net.async.EventDispatcher.processNetworkEvents > (EventDispatcher.java:759) > at com.google.net.async.EventDispatcher.internalLoop > (EventDispatcher.java:205) > at com.google.net.async.EventDispatcher.loop(EventDispatcher.java: > 101) > at com.google.net.rpc.RpcService.runUntilServerShutdown > (RpcService.java:251) > at > com.google.apphosting.runtime.JavaRuntime$RpcRunnable.run > (JavaRuntime.java:394) > at java.lang.Thread.run(Unknown Source)
