I am getting a (500) Internal Server Error when I try accessing my Web
Service with a client.
My question is: is there a simple way to debug this problem and find out
what the 500 code means? I am in a tight schedule (!) and would rather not
wade through all of axis looking for the cause... So if you've been here
before, please share it :-)
The client is using the generated skeleton code from WSDL2Java and
Java2WSDL. The client is pretty simple:
public class MathClient
{
public static void main(String [] args)
{
try {
MathServiceServiceLocator msl = new MathServiceServiceLocator();
MathService ms = msl.getMathService();
if (ms != null){
double d = ms.add(1,1);
System.out.println("Double returned:" + String.valueOf(d));
}
} catch (Exception e) {
System.err.println(e.toString());
}
}
}
The service is also simple:
public class MathService
{
public double add(double d1, double d2)
{
return d1+d2;
}
}
The generated WSDL is:
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions
targetNamespace="http://localhost:8080/axis/services/MathService";

and the deploy file is:
!-- Use this file to deploy some handlers/chains and services -->
<!-- Two ways to do this: -->
<!-- java org.apache.axis.client.AdminClient deploy.wsdd -->
<!-- after the axis server is running -->
<!-- or -->
<!-- java org.apache.axis.utils.Admin client|server deploy.wsdd -->
<!-- from the same directory that the Axis engine runs -->
<deployment
xmlns="http://xml.apache.org/axis/wsdd/";
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java";>
<!-- Services from MathServiceService WSDL service -->
<service name="MathService" provider="java:RPC" style="rpc" use="encoded">

Any help would be GREATLY appreciated...
Thanks,
