Hello Bastian:
I had read the information you posted in your reply. But I don't want to hand over URL query parameters, I need to fill the POST body. For two reasons: 1) The Web service expects my payload in the body, not in the URL query. 2) The URL query string is limited to 1024 characters, which may not be enough.
As to the second part of your reply on how to convert to JSON, the JSON conversion is already complete and correct, I have one of those snippets in an earlier atom and they work fine.
The problem really is the POST body going out in blank with no content at all, unless the pltype parameter is set to xml, but then it is including the XML definition and a dummy root tag which messes up the content.
Any more ideas?
Thanks,
Joerg.
