JCA with EP6 SP2

Hello,

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

Michael

    Hi,

    First I would create a direct connection using the SAP Connector framework. If this is working I would increase the complexity using the examples. Starting with SSO might be a little bit to optimistic 😉

    I solved the problem: our CRM System was wrongly created in our portal from the SAP template for "load balancing" instead of "dedicated". I didn't entered the system into our portal so I didn't know you can't change it after creation. So I had to create a new system from the right template.

    Cheers,
