Re: Can't call a Web Service from a Servlet

[Johann RENEL]

Hi,

Your import are correct, just the jaxrpc.jar is a dependance for Axis. 
jaxrpc.jar must be in the same directory as axis.jar etc.

BR,

Hi Johann,

that is strange indeed. 
I do have jaxrpc.jar and it does contain a class Service,
javax.xml.rpc.Service to be precise.
But may be here is the problem, my Servlet contains the following
imports:

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.net.URL;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

Doesn't that mean that it interprets the Service in the code
as being of class org.apache.axis.client.Service instead of
javax.xml.rpc.Service as I intended (though in these details
I am not completely sure what I really intend) ?
The axis Service class is also there (in axis.jar).

Thanks & regards,
Juliane.

Hello,

Hi all,

I am trying to invoke a Web service from a servlet. Since the servlet 
is supposed to be able to be dynamic w.r.t. the Web service's name, I 
am using a generic way to invoke the service as follows:

     Service service = new Service();
     Object ret;
     try
        {
         Call    call    = (Call)service.createCall();
         call.setTargetEndpointAddress(new URL(wsEndpoint));
         call.setOperationName( new
javax.xml.namespace.QName(wsNamespace,wsMethod));
         ret = call.invoke(val);

The service is deployed and accessible by a Java application using the 
same invoke method.
When running the servlet, I am getting an NoClassDefFoundError error 
pointing to the line that contains the new Service() statement (the 
full error report is attached below).


This message indicates the jaxrpc jar is missing. Axis needs the Service 
interface (of jaxrpc) to implement the Service class.


have failed to understand how to make archives known to a servlet. 
Isn't it enough to get the servlet compiled and provide the jars in 
the Web application's lib sub-directory ?


yes, generaly that's the way

BR,

Johann
