Error when IdentityXML is called

Question

Hi all!
I'm working with OAM and trying to call an IdentityXML function to create a new user from outside of product using this API.
I read de documentation (http://download.oracle.com/docs/cd/B28196_01/idmanage.1014/b25346/toc.htm) and I can't put this to work.
When I call the function the only answer is a "No Content Length found" error, I try with a client in java, PLSQL, wget and nettool with the same result in all the cases. The same error is loged on Apache Error Log.
The error is detected even if another function is call or just completely empty the message.
OAM version 10.1.0.4
Linux
Please, I need this working but I can't find a solution, is really urgent.

Answer 1

There is some more data:
The error is raised with any POST request to webservice endpoint:
http://host:port/identity/oblix/apps/userservcenter/bin/userservcenter.cgi
The error is always the same when endpoint is called with a POST (like a webservice!) ... but when is called with GET the User Console Page is returned
Follow in this post paste a request/response example from HTTP point of view, this was taken from a HTTP Tunnel.
The api is well used?? I'm using IdentityXML well??
Thanks for advance.
