Error generating client stubs using eclipse

[Asha Pathik]

Hi,

I'm trying to create clients using eclipse from a wsdl file and it is giving me following error:

Exception occurred during code generation for WSDL  : org.apache.axis2.AxisFault: Duplicate operation with name=GetPVDataYearList, found in portType '{http://www.clean-power.com/estimator}EstimatorWebServiceSoap'.

When I checked the wsdl it does have some duplicate names but then it is working fine in current application setup. Any pointers to generate stubs without errors would be really helpful.

Thanks,
Asha

Use SoapUI, create a client using the WSDL. See if you get the same error. If not, use SoapUI for your testing.

Hi Asha,

If WSDL contains duplicate operation names, it wouldn't work. First, check for well-formedness and validation of WSDL, then generate client stubs.
