Dynamic Proxy Not working

[Venkatesh Rangamani]

Ranchers,
I encountered a strange problem, when try to access a Document Style webservice using Dynamic Proxy i am getting exception as below:

port: {http://com.venkat.webservice/AllInOne/targ}AllInOneIntfPort does not contain operation: justConcat
at com.sun.xml.rpc.client.dii.ConfiguredCall.configureCall(ConfiguredCall.java:98)
at com.sun.xml.rpc.client.dii.ConfiguredCall.configureCall(ConfiguredCall.java:69)
at com.sun.xml.rpc.client.dii.ConfiguredCall.setMethodName(ConfiguredCall.java:50)
at com.sun.xml.rpc.client.dii.DynamicProxyBuilder.buildDynamicProxyFor(DynamicProxyBuilder.java:66)
at com.sun.xml.rpc.client.dii.ConfiguredService.getPort(ConfiguredService.java:250)
at wsclient.DynProxy.main(DynProxy.java:50)

I am using Sun Application Server for J2EE 1.4 . I deployed a stateless session bean as a webservice.

But when i create a RPC Literal webservice for the same bean i am able to access the Webservice through Dynamic proxy.

Is there any bug in Sun server w.r.t accessing a Document style Web service with Dynamic proxy.

Thanks
Venkat
