Using Studio to develop DII Client for DiningGuide example

Question

Hi,
I am trying to develop a DII client to the DiningGuide example from the Java Studio Enterprise Tutorials and Code Camps:
http://developers.sun.com/prodtech/javatools/jsenterprise/learning/tutorials/index.html
I am using Studio6 with Application Server 7 update 3 with Java WSDP 1.3 [JAX-RPC 1.1 support]
The question is how does Studio support JAX-RPC DII client development ? I understand that the config.xml file is different between Static stub based client and a DII client. Please let me know as to how to configure
Studio to do this.
Below is the code that is new in the DIIClient shown in 3 sections:
- imports area in CustomerReviewTable.java
- getCustomerReviewByName method in CustomerReviewTable.java
[Basically taking the code from
http://java.sun.com/webservices/docs/1.0/tutorial/doc/JAXRPC6.html#75222
        and modifying this to use this service and make appropriate
changes for the return value (Vector).
        I suspect that this is where the problem is but need help to fix
it. - Thanks!!]
- Variables declaration new for DIIClient
- The WSDL for the DGWebService service is also shown
I tried it with both JAXRPC 1.0 and JAXRPC 1.1 [Setting this for the
Service in Studio 6] and regenerating the Service code
but did not see any difference.
Right now, with the code shown below, I do not get any exceptions, but
it doesnot show any reviews [Vector returned is null].
Really appreciate your help,
Sridhar.

you may have a little better luck in the JNI forum.
