Basically what I'm trying to do is to create a simple Web Service that will receive a String and retun the same string, i.e. basically an "echo" web service. I tried using the sample on the Axis2 documentation page with OMElement - it works fine.
My problem is that I want to use String instead of OMElement on both sides (server as well as client). Apparently, I cant do this unless I use the RPC
So what I have is a services.xml that looks like this:
A MyService2.java that looks like this:
public class MyService2 {
public String echo(String echostring) {
return echostring;
}
}
I can deploy this using axis2.war on JBoss. It deploys fine, and I get the following WSDL:
<wsdl:definitions

I then try to use WSDL2Java to create client stubs based on this WSDL. It does generate them, but when I try to run the client I get the following error:
Exception in thread "main" java.lang.RuntimeException:
java.lang.RuntimeException: Unexpected subelement return

... 2 more
I googled this and this page (
http://mail-archives.apache.org/mod_mbox/ws-axis-dev/200605.mbox/[EMAIL PROTECTED]) claims
that this error message appears because axis2 does not support RPC Bindings.
I'm confused - how do I generate a client for this WSDL?
