Error when test an INterface with SOAP Sender CC

Question

Hello everybody,
I'm testing a Scenario that goes as follows Web Service Consumer-> PI 7.0 -> RFC, now I've already tried to test it with Altova XML Spy, and with the WebServcies Navigator Tool of UDDI, now I'm getting the next error in both cases:
HTTP/1.1 500 Internal Server Error

Server: SAP J2EE Engine/7.00
Content-Type: text/xml; charset=utf-8

Check if the XI RFC destination is working fine. ALso check the sap note no.804124, 807000 .
Thanks!
