Hi All, I know this question should be answered somewhere but i'm not able to get a concrete answer. I need to write an axis client to invoke an asynchronous web service. When i google for this information i get information of only axis2. Doesn't axis 1.x support asynchronous invocation? I checked out axis2 approach on this and i'm not able to use this because the web service i have to invoke supports only 2003/03 ws addressing whereas axis2 supports only submission and final version. Any version of axis supporting 2003/03 addressing? Thanks in advance for any response.
