Hi,
I am trying to get the BPEL hello world sample running in Tuscany M5.
I start the node inside the Activator of the jar file:
String location =
ContributionLocationHelper.getContributionLocation(Activator.class);
node = NodeFactory.newInstance().createNode("helloworld.composite", new
Contribution("test", location));
Hello bpelService = node.getService(Hello.class, "BPELHelloWorldComponent");
String result = bpelService.hello("Hello"); System.out.println(result);
The file structure of the jar is the following:
helloworld.bpel
helloworld.bpelex
helloworld.composite
helloworld.wsdl
log4j.properties
META-INF
MANIFEST.MF
sca-contribution.xml
de/fhg/fokus/ngni/xposer/see/service/bpel
Activator.class
Hello.class
The only things I changed in the sample is the namespace in the
composite and contribution from
xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200903 to
xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200912.
Now the following error occurs:
26.07.2010 11:42:05
org.apache.tuscany.sca.implementation.bpel.xml.BPELDocumentProcessor
[Contribution: test, Artifact:
META-INF/maven/de.fhg.fokus.ngni.xposer.see.services/service.bpel]

I guess that the BPEL document cannot be found. But I did not find a way
to point on the file in the sample.
Thanks in advance for some advice.

Alex,
It would be interesting to know more how you are starting the JAR.
The error itself implies that Tuscany is reading your contribution and thinks
it has found a file:
META-INF/maven/de.fhg.fokus.ngni.xposer.see.services/service.bpel
When it tries to read that file it gets an exception.
Given that you claim the JAR layout as above, that such a file should be found seems more than a
little surprising.
One interesting question is just what location you get for the contribution - how about printing out
what you get for "location" in the code above?
Yours, Mike.
