Hi,

I'm using JBoss 5.1.0.GA for the Web Service deployment. Please find attached the relevant code snippets in "Code snippets.txt".

Refer to the "Client code" section # 2 in the attached code snippet. The call seems to be failing some time after the Web Service method returns at the following line:

+System.out.println("Making the dynamic invocation of the Web Service method now...");
HelloResponseVO responseVO = (HelloResponseVO)call.invoke(params);
+
I'm getting the following exception when invoking the WebService method from the client:

*Note:* The problem seems to be only when the return type from the Web Service method is a complex type data (a POJO)Things are working fine when I use the primitive data types instead of POJOs.

Messages at client-side:

I have tried changing the occurrence modifiers wsdl without luck..

From:

    <xs:sequence>
     <xs:element minOccurs='0' name='name' type='xs:string'/>
     <xs:element minOccurs='0' name='fullGreetingMessage' type='xs:string'/>
     <xs:element minOccurs='0' name='greetingMessage' type='xs:string'/>
    </xs:sequence>
   </xs:complexType>+

To:

 +<xs:complexType name='helloResponseVO'>
    <xs:all>
     <xs:element minOccurs='0' name='name' type='xs:string'/>
     <xs:element minOccurs='0' name='fullGreetingMessage' type='xs:string'/>
     <xs:element minOccurs='0' name='greetingMessage' type='xs:string'/>
    </xs:all>
   </xs:complexType>+

Any help in this regards will be highly appreciated.

Thanks in advance...
