Re: Bug with PojoGuide clone

[Garth Keesler]

Hello and Thanx for the reply! I'm running Tomcat v5.5.20 and Axis2 v1.1. The full stackdump is in the tar file but here's a copy. Note that I trap the error and request the stackdump in the code.: rpc.client.run:      [java] Endpoint found.      [java] targetEPR set.      [java] QName set.      [java] Ready for call.      [java] Error returned - null      [java] java.lang.NullPointerException      [java]     at org.apache.axis2.databinding.utils.BeanUtil.deserialize(BeanUtil.java:294)      [java]     at org.apache.axis2.databinding.utils.BeanUtil.processObject(BeanUtil.java:549)      [java]     at org.apache.axis2.databinding.utils.BeanUtil.ProcessElement(BeanUtil.java:499)      [java]     at org.apache.axis2.databinding.utils.BeanUtil.deserialize(BeanUtil.java:438)      [java]     at org.apache.axis2.rpc.client.RPCServiceClient.invokeBlocking(RPCServiceClient.java:97)      [java]     at com.ttna.rpcclient.wsVendorClient.main(Unknown Source)      [java]     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)      [java]     at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)      [java]     at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)      [java]     at java.lang.reflect.Method.invoke(Method.java:585)      [java]     at org.apache.tools.ant.taskdefs.ExecuteJava.run(ExecuteJava.java:202)      [java]     at org.apache.tools.ant.taskdefs.ExecuteJava.execute(ExecuteJava.java:134)      [java]     at org.apache.tools.ant.taskdefs.Java.run(Java.java:710)      [java]     at org.apache.tools.ant.taskdefs.Java.executeJava(Java.java:178)      [java]     at org.apache.tools.ant.taskdefs.Java.execute(Java.java:84)      [java]     at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:275)      [java]     at org.apache.tools.ant.Task.perform(Task.java:364)      [java]     at org.apache.tools.ant.Target.execute(Target.java:341)      [java]     at org.apache.tools.ant.Target.performTasks(Target.java:369)      [java]     at org.apache.tools.ant.Project.executeSortedTargets(Project.java:1216)      [java]     at org.apache.tools.ant.helper.SingleCheckExecutor.executeTargets(SingleCheckExecutor.java:37)      [java]     at org.apache.tools.ant.Project.executeTargets(Project.java:1068)      [java]     at org.apache.tools.ant.taskdefs.Ant.execute(Ant.java:382)      [java]     at org.apache.tools.ant.taskdefs.CallTarget.execute(CallTarget.java:107)      [java]     at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:275)      [java]     at org.apache.tools.ant.Task.perform(Task.java:364)      [java]     at org.apache.tools.ant.Target.execute(Target.java:341)      [java]     at org.apache.tools.ant.Target.performTasks(Target.java:369)      [java]     at org.apache.tools.ant.Project.executeSortedTargets(Project.java:1216)      [java]     at org.apache.tools.ant.Project.executeTarget(Project.java:1185)      [java]     at org.apache.tools.ant.helper.DefaultExecutor.executeTargets(DefaultExecutor.java:40)      [java]     at org.apache.tools.ant.Project.executeTargets(Project.java:1068)      [java]     at org.apache.tools.ant.Main.runBuild(Main.java:668)      [java]     at org.apache.tools.ant.Main.startAnt(Main.java:187)      [java]     at org.apache.tools.ant.launch.Launcher.run(Launcher.java:246)      [java]     at org.apache.tools.ant.launch.Launcher.main(Launcher.java:67) BUILD SUCCESSFUL Total time: 6 seconds I've tried "implements Serializable" on the main class since the trace references "deserialize" but it had no visible impact. I really appreciate any help you can provide. Thanx, GarthK Deepal Jayasinghe wrote: Hi Garth ; What the Axis2 version are you using ? and what is the exception.

BTW, this works great using Eclipse and WTP but only on the same server which sort of limits the approach. Attached is a tar file of a simple PojoGuide clone that I have spent days on trying to clear the last bug. I am getting a null return in the rpcclient but the service, located on another box, seems to be running correctly. I've tried a variety of things to clear the error but I can't figure out what's wrong. The Diags folder in the tar file shows the stackdump as well as the trace output from the web service. All of the source and build.xml files are included. Help greatly appreciated.
