That takes us back to my
old posting dated 5th July Subject : "Re: Communication problem between
Apache-Axis WebService and JWSDP client", where I have metioned
problems implementing a static stub client for Web Service.
Kathy replied to that mail suggesting testing against JWSDP1.4 but we
have already implemented all the clients using JWSDP 1.3 and would like
to move only when the problem appears to be linked with JWSDP
libraries. I am attaching my Static stub client implementation with
this mail.
I am able to create a proxy for the WebService, but when I call any
WebService methods, I get following exception :
java.rmi.RemoteException: Runtime exception; nested exception is:

I have taken a look at your wsdl.
It is more than a bit complicated for a dynamic proxy client
and uses attributes which that dynamic client does not currently
support-
My best suggestion is to use static stubs for your client program.
JAXRPC 2.0 will be fixing many dynamic client problems-

Hi
Please find attached WSDL file and a simplified client program.

Please send the wsdl you are using
and your
client program or a simplified one-
I will take a look-

Hi,
I am implementing a Web Service client and coming across Serialization
problem. In Web Service there is a method with following signature :
OrderResponse order (OrderRequest request)
OrderRequest and OrderResponse both are user defined defined complex
types implemented as JavaBeans. Skeleton of OrderRequest class is :
package com.aol.fog.fr.objects;
public class OrderRequest extends OrderRequestCommon {
private Address adsl_address = null;
/....
../
public Address getAdsl_address() {
return adsl_address;
}
public void setAdsl_address(Address adsl_address) {
this.adsl_address = adsl_address;
}
Address again is a Java class implemented as JavaBean with following
code :
package com.aol.fog.fr.objects;
public class Address {
private String title;
/...
../
public Address() {
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
/...
}
I use wscompile to generate stub classes for the webservice in package
: com.aol.fog.fr.objects
In the client code :
Address adslAddress = new Address();
adslAddress.setTitle("test");
OrderRequest request = new OrderRequest();
request.setAdsl_address (adslAddress);
//Create proxy for web service etc
try {
OrderResponse response = myProxy.order(request);
} catch (Exception exc) {
System.out.println ("Error while calling order method on FOG
Web Service");
System.out.println(exc.getMessage());
exc.printStackTrace();
}
The call throws following exception :

greatly appreciated.
