Hi Alex,
I tried to design the process with the BPEL Designer and it asks me if I
want to initialize the variable. I say yes and expect it to be done. Is this
the problem? Do I have to do something more? More precisely: How do I
initialize the variable correctly? The examples in ODE use only variables
with one part and I don't have an idea what to do, not in terms of BPEL code
nor in terms of using Eclipse BPEL Editor the right way ... Maybe you can
provide an example at least in BPEL code, but I wonder if I am the first one
who tries to use Eclipse BPEL to call a webservice that takes to parameters.
I really can't believe that, so I am quite sure that I am doing something
wrong.
Regards,
Andreas
