Hi Michael I would suggest you to read following articles, then you can get better idea about Axis2 service and how to invoke them.
to understand POJO in axis2 :- http://wso2.org/library/2893 To understand Axis2 client side :- http://today.java.net/pub/a/today/2006/12/13/invoking-web-services-using-apache-axis2.html > OK. Is it me? I know I'm 1) not understanding Axis2's API and > therefore 2) not using it correctly. > > For the past three weeks I have been unable to get anything but the > simplist web service to work. By simplest I mean a web service that > passes and returns only primitives (i.e. int, float, String, > etc....). I have been following the examples I found on the web > (bottom-up web services with Axis2) and on the Apache Axis2 web site ( > bottom-up development web services with Axis2 and POJO's).
