Hi Luciano,
Maybe this helps a bit:
I had a look into your test case. I think the transaction is OK, it's just seems
that the result message is not assembled correctly - the debug output says
(formatted
for better readability):
::result message::
<?xml version="1.0" encoding="UTF-8"?>
<message>
<getGreetingsResponse>
<return>Hello Luciano</return>
</getGreetingsResponse>
</message>
but the BPEL afterwards wants to read a <parameters> elements from
this response:
<assign name="assignToHelloResponse">
<copy>
<from>$greetingsResponse.parameters</from>
<to>$helloResponse.TestPart</to>
</copy>
</assign>
When I change this to (just for a test, I know that it's not correct ;-)
<from>$greetingsResponse</from>
the test case at least receives a result, but cannot find the expected string
value:
junit.framework.ComparisonFailure: expected:<Hello Luciano> but was:<>
at junit.framework.Assert.assertEquals(Assert.java:81)
at junit.framework.Assert.assertEquals(Assert.java:87)
at
helloworld.HelloWorldTestCase.testServiceInvocation(HelloWorldTestCase.java:61)
However, I'm not sure at which point in the process is the error - I'm a bit
confused about how which part of the WSDLs relate to which parts of the
messages and interfaces (-; I keep trying ...
Cheers,
Juergen
