如何在Java中创建无存根的Web服务客户机?

We are using Axis2 in our enterprise currently. Our project involves making call to multiple webservices for fault diagnostics. The problem is that very frequently we have changes in WSDLs (which are non-life threatening as in new data-types and services just get added, very rarely is something dropped) due to which we have to upgrade our application as well. Basically, we have a to get a new copy of the WSDL, run it through WSDL2java and use the new jars, run our unit tests and package the new jars and install on production.We are using Axis2 in our enterprise currently.
