"wsclients/proxies/sap.com/ClientProxyDefinition/in.mobileone.demo.proxy.WSClientProxy");

out.println("\n----2---"+lookuped.getClass());

PortableRemoteObject objPortableRemoteObject=new PortableRemoteObject();

out.println("\n---3--

---

");

Object narrowed =

objPortableRemoteObject.narrow(lookuped, AdminOperWS.class);

out.println("\n---4--" + narrowed);

AdminOperWS service = (AdminOperWS) narrowed;

out.println("----5---" + service);

AdminOperWSViDocument client = null;

ClsSuper objClsSuper = new ClsSuper();

String strErrorCode = null, strErrorMessage = null;

client =

(AdminOperWSViDocument) service.getLogicalPort(

"Config1Port_Document",

AdminOperWSViDocument.class);

out.println("----5---" + client);

Hi Lakshman,

Definetely the object which you are trying to use for casting doesn't match with which you got from JNDI reference.

Try to see the code of your both classes. This is the only solution for this problem,

Hi Lakshman,

In case of Deployable proxy projects, you shold be creating objects of the Service End Point Interfaces (SEI) generated in the Proxy Project, and not the way you are doing it.

You can refere the following link for this.

[Creating a Client Bean|http://help.sap.com/saphelp_nw04/helpdata/en/81/12703e5da3e946e10000000a114084/frameset.htm]

Hi Lakshman,

can you please elaborate how you are calling this web service( where you get the stub?)

Why are you using these lines?

PortableRemoteObject objPortableRemoteObject=new PortableRemoteObject();

out.println("\n---3--

---

");

Object narrowed =

objPortableRemoteObject.narrow(lookuped, AdminOperWS.class);

out.println("\n---4--" + narrowed);

These are used mailny for CORBA objects( while calling EJBs).

Just remove these line and try.

Please do come back with the output.

Regards,

Piyush
