JCA with EP6 SP2



I would like to try to use the JCA instead of JCO to call RFC function modules of a CRM system. My problem is, that I can't establish a connection. The IConnection is always "null". Even the demo that comes with the PDK is not working (IConnection also "null").

Question: Has anybody an Idea or can help?

A little bit of background information:

I created a system alias "PDK_R3_BACKEND", but I couldn't find the settings for SSO. I went to

- Component Manager > Getting Started > Services > Schlüsselspeicher-Administration > Konfiguration für Benutzerverwaltung

but when I click on "SAP-System", our portal crashes with an "out of Memory" error. Could that be the reason that I cant connect to any system?

Another thing I searched for is the connection test in:

Java Developer > Development > Support Desk > Connection Testing

I cant find it on our portal.

Thanks for any help in advance
