Issue with SSL in web service.

Hi All,

We are having synchronous web service to proxy scenario in XI. We are trying to send a binary data using the SOAP web service to SAP via XI. Initially, we were posting large binary data using HTTP connection via XI from the SOAP client. The scenario was working without any issues.

Since the data is sensitive changed the web service from HTTP to HTTPS.The interface works without issues when we test it using the SOAP client for testing. When the data is sent using the Dot Net application (the end application) using the same webservice, URL (HTTPS connection) the message errors out. The connection is borken and the message fails. In this scenario, XI does not even receive the message which I can make out looking into the SOAP adapter communication channel.

The interesting fact here is the same Dot Net application is able to connect and send smaller binary data using HTTPS connection.

Could you please let us know if this could be the issue with HTTPS connection on XI side? I doubt it to be an issue on XI side because the adapter does not even receive any message when the scenario fails. But we used some HTTPS monitoring tools and found that the Dot Net Application receives some encrypted response from the server which the application is not able to decrypt and the handshake breaks.

Could you please throw some inputs into this issue.

Thanks,

Manohar.

The issue is resolved by making changes to the dot net code. The code is changed so as to pass the username and password at the time of handshake between the legacy dot net application and the PI Server.
