Invalid request when calling REST-webservice with UTL_HTTP.

10-11  Source: Network gathering  Views:12 

When i try to send some data to a REST-webservice i get as response "INVALID REQUEST"
I Think it is about the request-body that seems to be no UTF-8.
I tried to set the characterset with utl_http.set_body_charset(t_http_req, 'UTF-8').
But when i read the characterset with utl_http.get_body_charset(t_charset);, is still get "ISO-8859-1"
I am using: Oracle Database 10g Express Edition Release - Product
Some help would realy be appreciated because i am out of options trying to get the code working..
======MY CODE==========

Always check the access_log and error_log files of the Apache web server in such a case. This will identify whether the error comes from Apache itself, mod_plsql, the Apex run-time engine, or the Oracle database.
I see that you're creating a HTTP/1.1 in PL/SQL - however, the web server response indicates a HTTP/1.0 call was received. Unusual. And could be part of the problem.
