BPEL generate-artifacts error

[frostp]

Hi,

I am trying to simply make an external web service invocation from a BPEL script. I am basing the project on the HelloWorld example.

JbossAS-4.0.4.GA
JBPM-bpel-1.1.Beta3
jdk1.5.0_11

OK so i can successfully run:

ant deploy-definition
ant generate-service

But when it comes to

ant generate-artifacts

I get the following output:

D:\development\jbpm-bpel-1.1.Beta3\examples\listadmin>ant generate-artifacts
Buildfile: build.xml

detect-wsgenerator:

generate-artifacts:

setup-wstools:

I'm pretty sure the namespace for the complex "ServiceListRef"type is correct (well, I did create that webs ervice so it could be wrong)
How can I place an import into a temporary file?

I know that Ant says it has completed the task but when I run

ant deploy

the javac compiler can not see the auto generated Greeter.class and moans, so it can not have worked.


My config looks thus:

Any clues anybody?

Apparently inline XML Schemas are handled by copying them to temporary files. While the error message may be misleading, it does indicate that definitions in your second schema cannot be located.

Some items in the first schema reference items that are defined later in the second schema. Try moving the second schema above the first.

Apart from that, consider that wstools currently does not support multiple namespaces and all generated artifacts will end up in the same java package. You might want to use wscompile instead.

[frostp]

HI,

Thanks for the suggestions.


Swapped the order of the in-line schema but had no effect.

Also installed jwsdp2.0 and set up wscompile. Running this allowed me to generate-artifacts and deploy but the error message I got from wstools on my client side from before now appears on the server side and exceptions are thrown.

Is this problem related to http://www.jboss.com/index.html?module=bb&op=viewtopic&t=101479 ?

[aguizar]

Do you get the exact same exception? It'd be useful to see the stack trace, just to verify.

[frostp]

Hmmm,

Nope, it's a different exception it just prevents the WAR file from being built.

The stack trace is:

Also I have quickly generated a "simpler" web service to invoke from my BPEL script. It has just two strings as input parameters, and I basically get to the same error state (above).

[aguizar]

The target generate-service creates binding and service definitions for your process. Look at the WSDL files it produces. The WSDL file that contains the service definition should have a targetNamespace that matches your BPEL file's:

<definitions targetNamespace="urn:samples:listadmin">
 <import .../>
 <service name="ListAdminService">
 <port name="GreeterPort" ...>
 <soap:address .../>
 </port>
 </service>
</definitions>

Therefore the wsdl-port in your webservices.xml should be something like:

<wsdl-port xmlns:portNS="urn:samples:listadmin">
 portNS:GreeterPort
</wsdl-port>

I am guessing it looks like this instead:

<wsdl-port xmlns:portNS="http://jbpm.org/examples/listadmin">
 portNS:GreeterPort
</wsdl-port>

Remember that the deployment model for BPEL processes is essentially equal to normal web services. When you are unsure about a setting, refer to Web Services for J2EE documentation or this forum for help. Literal text replacements might not always be enough.
