Generate Service Control for WSDL: NullPointerException

Question

Steps to demonstrate the problem: in Platform Workshop (8.1.4) in Integration mode, create a Tutorial Process Application, then for RequestQuote.jpd, Generate WSDL file, then for that WSDL, Generate Service Control.
<pre>ERROR: requestquote/RequestQuoteContract.wsdl Line 0, Col 0: java.lang.NullPointerException
</pre>
The WSDL is valid (Axis WSDL2Java and Eclipse-Webtools are both okay with it, assuming I delete some cw and http namespaces they don't understand).
The problem is when the XSD is too deeply nested giving XML like /one/two/three, whereas /one/two is okay for WLI. This is valid XSD, but apparently too deep for WLI to understand.
Any help debugging this more or working around it would be appreciated. Is there a way to run this process from the command line, so I might debug this more on my own? I'd like to give the stackTrace for the NPE, but WLI Workshop doesn't show that.
Thanks,
Mike

Hi guys,
I had the same problem and what I had to do was import the Schema project that holds all schemas included in the WSDL that I was trying to generate a control from. In my case I had the Schema project because I was the one that developed the WebService too, in your case it's possible that you have to create an Schema project and somehow extract the schemas from de WSDL and create .xsd files to put in the project.
After doing this you will see the popup window (when you try to generate a service control from the WSDL file) asking if you want to use the XMLBeans generated from the xsd files in your Schema project otherwise it will generate inner classes based in the WSDL's schemas, you must choose YES (use the existing XMLBeans) and that should be it for creating a Service Control based on a WSDL file.
Hope this helps in most cases.
