Content is not allowed in prolog

Hello,

I'm trying to connect our SAP system to SalesForce CRM. We need to create a HTTPS connection to consume some WS.

I created the SM59 connection, uploaded the certificates in the STRUST tode and uploaded the WDSL file into the SAP system. Finally, I created the proxy in the SOAMANAGER envoirment. The SM59 connection returns a 405 message (GET not supported) and when I execute the proxy ping test, I get the return code 405 (HEAD not supported).

When I call the login method, I receive this error: "UNKNOWN_EXCEPTION: Content is not allowed in prolog", and I don't know why receive this error.

Can anyone help me to solve this issue?

Thanks in advice,

Toni.
