Hi
I get a Null pointer exception when I try to generate code using
wsdl2java for stubs.
I have a WSDL file which I refactored and moved common used data types
to a common schema (common.xsd) which I import in the main WSDL file.
I'm able to generate the server side code and deploy the service
successfully. I could see this through the axis admin console.
I have packaged the required common schema with the WSD file itself in
the aar file. After deploying the service I can see my WSDL file also
http://localhost:8080/axis2/services/CertifyChannel?wsdl.
Now when I try to generate the code I get the following error. Is there
any specific place I have to place the common.xsd that I have generated?
[java] Retrieving schema at 'common.xsd', relative to
'http://localhost:8080/axis2/services/Cer
tifyChannel?wsdl'.
