Hi Vibhor, Try to save the WSDL to a file and then use WSDL2Java by passing the wsdl file as parameter.

Just an addition to this I have set the <parameter name="useOriginalwsdl">true</parameter in the service.xml file and I can see my own wsdl file but when I generate the code at the client site it throws the exception as described below. Now if I do not set this value I can generate the stubs and interestingly I see that in the automatically generated wsdl <xs:import namespace="http://common.ws.gryphonnetworks.com/xsd"; schemaLocation="*CertifyChannel?xsd=xsd0*" /> Is shown Whereas in the actual one it is <xs:import namespace="http://common.ws.gryphonnetworks.com/xsd"; schemaLocation="common.xsd" /> Why does the code generator changes this?

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'.
