HTTP response fails

Hi all,

I’m receiving requests via HTTP/Post into IS.
The service I wrote, expects a node and returns a xmldata. This service validates the incoming XML, publish it into the broker and ends with a pub.xml:documentToXMLString call to respond with a acknowledgment XML to the sender. It´s working fine.
Now I need to do an update into DB after the pub.xml:documentToXMLString call, but when I call my adapter service that do the update, I’m not receiving any response from HTTP.
I tried to call the adapter service before the pub.xml:documentToXMLString call and it doesn´t work too.

I’m using wM6 (IS 6.0.1+SP2, Broker 6.0.2+SP1, JDBC 6.0.3).

Any tips?
