Dear Jörg, Inaki and Sudhansu,
Thank you very much for all responses. They all are were helpful and very interesting.
Following options could be used to see more about the responses:
-XPI-Inspector is also a great tool to check many problems (SSL, .Adapter issues, ..).
-Finally I installed wireshark on my XI-Server and I got the http request leaving my system. So I could see the request created by my adapter.
(I was trying to create the envelope and the wsse security tags with mapping. I found out I need an AXIS-SOAP Adapter to deal with wsse security tags.)
Many Thanks
Armin
