Alfresco and Oracle BPEL

[ldeltenre]

Hi,

I try to use Alfresco with Oracle BPEL.

Actually I can display existing documents but when I try to create, for example, a new folder I receive a JavaNullPointerException.

I follow all the steps  like the webservice samples and it does not work !

Anyone can help me ?

Thanks

Laurent

Hi,
it is very hard to help you if you're only saying I'm getting a NullPointerEx. I would be very helpful if you post some code and stack traces whicj describes your problem.
Cheers, jan

Hi,

My config is
-Oracle Soa Suite 10.1.3.3
-Alfresco community  2.1.0 (build 482)

First step is a connection to a BPEL (Alfresco_Authentication) that create wsseHeader message
Second step try to create a simple folder in alfresco
Third step is a connection to a BPEL (Alfresco_Disconnect) that close alfresco session

Here you can find my BPEL code.
