Answer 1

the Java process is having a communication issue with the ABAP stack. First 3 things I would look at:
1. is the ABAP stack up and running? The Java stack is checking for a user installed in the ABAP stack.
2. is sapgw00 service defined in the services file? should have been done by the installation, but I've seen this fail.
3. is host ISLLSOLM listening on the port defined as sapgw00? If this is not true, any number of things could be wrong.
