I have switched over a new project to GWT 2.6.0. I running with Maven and the GWT Maven Plugin 2.6.0-rc3.
Everything was working swimmingly with GWT 2.5.1. Now I'm getting GWT-RPC serialization errors when running SuperDevMode. If I start DevMode from Maven (gwt:run) or through Eclipse, the classes that I have marked as implementing java.io.Serializable pass through the RPC layer without a hitch. However, serialization fails with SuperDevMode: - start SuperDevMode from a console with Maven and gwt:run-codeserver) - start the server though Eclipse in Development Mode - on the Development Mode messsage http://192.168.1.101:8888/Mobile.html?gwt.codesvr=192.168.1.101:9997, open the URL http://192.168.1.101:8888/Mobile.html - turn Dev Mode On and Compile Now executing the GWT-RPC method shows this in my console file: Starting Jetty on port 8888 [WARN] Exception while dispatching incoming RPC call com.google.gwt.user.client.rpc.SerializationException: Type 'com.optix.mobile.shared.AboutBoxData' was not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a custom field serializer.For security purposes, this type will not be serialized.: instance = com.optix.mobile.shared.AboutBoxData@adc7bb6 at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serialize(ServerSerializationStreamWriter.java:667) at com.google.gwt.user.client.rpc.impl.AbstractSerializationStreamWriter.writeObject(AbstractSerializationStreamWriter.java:130) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter$ValueWriter$8.write(ServerSerializationStreamWriter.java:153) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serializeValue(ServerSerializationStreamWriter.java:587) at com.google.gwt.user.server.rpc.RPC.encodeResponse(RPC.java:605) at com.google.gwt.user.server.rpc.RPC.encodeResponseForSuccess(RPC.java:471) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:563) at com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:265) at com.google.gwt.user.server.rpc.RemoteServiceServlet.processPost(RemoteServiceServlet.java:305) at com.google.gwt.user.server.rpc.AbstractRemoteServiceServlet.doPost(AbstractRemoteServiceServlet.java:62) at javax.servlet.http.HttpServlet.service(HttpServlet.java:755) at javax.servlet.http.HttpServlet.service(HttpServlet.java:848) at org.eclipse.jetty.servlet.ServletHolder.handle(ServletHolder.java:686) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:501) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:137) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:557) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:231) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1086) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:428) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:193) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1020) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:135) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:116) at org.eclipse.jetty.server.handler.RequestLogHandler.handle(RequestLogHandler.java:68) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:116) at org.eclipse.jetty.server.Server.handle(Server.java:370) at org.eclipse.jetty.server.AbstractHttpConnection.handleRequest(AbstractHttpConnection.java:489) at org.eclipse.jetty.server.AbstractHttpConnection.content(AbstractHttpConnection.java:960) at org.eclipse.jetty.server.AbstractHttpConnection$RequestHandler.content(AbstractHttpConnection.java:1021) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:865) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:240) at org.eclipse.jetty.server.AsyncHttpConnection.handle(AsyncHttpConnection.java:82) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.handle(SelectChannelEndPoint.java:668) at org.eclipse.jetty.io.nio.SelectChannelEndPoint$1.run(SelectChannelEndPoint.java:52) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:608) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:543) at java.lang.Thread.run(Thread.java:744) [ERROR] 500 - POST /optixm/mobile (192.168.1.101) 57 bytes Request headers Host: 192.168.1.101:8888 Connection: keep-alive Content-Length: 137 X-GWT-Module-Base: http://192.168.1.101:8888/optixm/ X-GWT-Permutation: FAC089581D0988AAD23493D0B52C84AF Origin: http://192.168.1.101:8888 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1700.102 Safari/537.36 Content-Type: text/x-gwt-rpc; charset=UTF-8 Accept: */* DNT: 1 Referer: http://192.168.1.101:8888/Mobile.html Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Cookie: JSESSIONID=11w6l0ygma6brge4d71mphf48 Response headers Content-Type: text/plain If I implement AboutBoxData with com.google.gwt.user.client.rpc.IsSerializable vs java.io.Serializable, the class will eventually fail because of a member that uses java.io.Serializable. What could be causing this? I've cleaned my Maven tree down to pom.xml and src, but each time I get this error. Is there some new setting to gwt-maven-plugin? Is there some Eclipse plugin I should|should not be running? My Eclipse has installed m2e from http://download.eclipse.org/technology/m2e/releases/ and m2e-apt and m2e-wtp from http://download.jboss.org/jbosstools/updates/... I have removed the Jetty plugins I was using elsewhere. Thanks for y'all's help. I want to run 2.6.0 because I want to work with the latest MGWT SNAPSHOTS as they are available, and I don't want to give up SuperDevMode. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
