Hi WebService Experts
I have developed a very simple web service with JWSDP 1.5 and trying to deploy on tomcat50-jwsdp app server(JWSDP1.5 integrated Tomcat app server).
I am trying for JAX-RPC Service Endpoint and for this I have written following files:
/WEB-INF
/WEB-INF/web.xml
/WEB-INF/webservices.xml
/WEB-INF/mapping.xml
/WEB-INF/classes/math/MathFace.class
/WEB-INF/classes/math/MathImpl.class
/WEB-INF/wsdl/MathService.wsdl

and all these files have been packaged in math.war

Full source code for all these file is as follows:
web.xml
<?xml version="1.0" encoding='UTF-8'?>

math.MathFace.java Interface

package math;

import java.rmi.Remote;
import java.rmi.RemoteException;

public interface MathFace extends Remote {
public int add(int a, int b) throws RemoteException;
}


math.MathImpl.java Implementation class

package math;

import java.rmi.RemoteException;

public class MathImpl implements MathFace {
public int add(int a, int b) throws RemoteException {
return a + b;
}
}


After deploying the application when I am trying to access the application using http://localhost:8080/math/MathService, It is giving error message that math.MathImpl is not a servlet.

What I read from books is for JAX-RPC Service Endpoint our Java implementation class(math.MathImpl) acts as a servlet then why I am getting this error.
Is there anyone who have faced this problem earlier? Don't know how to solve this problem.

Any help please...

Thanks in advance for spending time on this problem...
