Hello,
Sorry to bother you with such a (hopefully) easy question, but I seem to be
stuck.
I am using servicemix servicemix-3.0-M1. I am attempting to write a very
bare bones BPEL process that
1) receives
2) assigns a literal to the response variable
3) replies
My problem is that when I run the BPEL process, I receive an error about the
response variable not being initialized. I have seen this before and my
solution to this was to simply assign a literal to the response variable
before the reply.
My main question is: How do I assign a literal to a variable? A related
question is where can I find documentation about the BPEL syntax expected by
the BPEL engine?
I have attempted the following:
<bpws:assign>
<bpws:copy>
<bpws:from>
<bpws:literal>2</bpws:literal>
</bpws:from>
<bpws:to variable="ConnectResponse" part="ConnectResponse"
query="/ns2:ConnectResponse/ns2:output"/>
</bpws:copy>
</bpws:assign>
but I receive the following error message stating that the BPEL cannot be
correctly parsed:
Retrieving document at 'connection'.
