Hi,
I am trying to call a BPEL service something similar to a helloworld-bpel from
my java-sca-service using interface.wsdl. When I start my SCA domain everything
works fine, but I get a Null Pointer Exception in my console window. The BPEL
service call executes fine, but I am not able to understand why this error is
generated.
Can someone help me understand why this is happening? The error in the console
is as given below.
Starting BPELMotionReactorService
- Using Embedded Derby :
jdbc:derby:D:\Prototype\java-sca-service\bin\database/jpadb
- Using DAO Connection Factory class

- OpenJPA will now connect to the database to attempt to determine what type of
database dictionary to use. To prevent this connection in the future, set your

your database (see the documentation for available values).
