vb.net client accessing jboss web service... Sounds easy, no?

[Frank Farkel]

This has had me banging my head for days [ ], and I have nowhere else to turn. Please tell me this is a simple mistake so I can get back to programming...

Quick version:

Any web service I try fails. Here is an example web service:

package gms.ws;

import javax.jws.*;
import javax.jws.soap.SOAPBinding;
import javax.ejb.Stateless; 

@Stateless
@WebService(name="HelloWorld")
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class HelloWorld {  
	public String echo(String sInput){
		sInput += "!!!";
	}
	public int addOne(int iInput){
		return iInput + 1;
	}
}

Here is what the eclipse project looks like:

drwxr-xr-x 6 pat users 4096 2009-03-27 20:39 ./
drwxr-xr-x 8 pat users 4096 2009-03-27 20:33 ../
drwxr-xr-x 3 pat users 4096 2009-03-26 14:21 bin/

drwxr-xr-x 3 pat users 4096 2009-03-25 21:55 src/

One thing I haven't messed with is the .classpath entry in the project which is:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
        <classpathentry kind="src" path="src"/>
        <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
        <classpathentry kind="lib" path="lib"/>
        <classpathentry kind="lib" path="lib/jboss-ejb3x.jar"/>
        <classpathentry kind="output" path="bin"/>
</classpath>

The WSDL generated from this service is:

<?xml version="1.0" encoding="UTF-8"?>

It all looks like it should to me, but I have yet to get a single WS working, so what do I know?!

It has been extremely confusing. Some say jboss shouldn't be run on Java 6, some say a web.xml file is needed, all tutorials say this should just work.

The VB.NET component is ridiculously simple, as it just calls http://server:8080/gmsTest/HelloWorld?wsdl and sees the wsdl file no problem, adds the proxy code, and all LOOKS just dandy.

I have spent days going in circles, trying everything I could read about, and keep running in circles. Can one of you more knowledgeable folks point me in the right direction? I'll write an article on my blog about how to do this (to help others) if you can help me get it working!

TIA (big time)!
