NPE exception using wsgen ant task with xmlbeans binding

Created: 05/Apr/06 04:53 PM   Updated: 05/Apr/06 06:29 PM
Component/s: XMLBeans, Generator
Affects Version/s: 1.0
Fix Version/s: 1.0

Time Tracking:
Not Specified

File Attachments: 1. XML File assessmet.wsdl (94 kb)
2. XML File build.xml (0.5 kb)


 Description  « Hide
Here is the website that I get the wsdl file: http://209.242.136.9/assessment/assessmet.asmx?WSDL.

I use WsGenTask to generate soap client codes with xmlbeans binding. I am using xfire1.0 release.

When I run the generate-ws-client target, I got java.lang.NullPointerException. How would I print out the stacktrace to find out where the NPE comes from? I have attached the wsdl and build.xml file. I think the wsdl file is generated automatically by .net application.

Thanks.

I use ant -verbose to print out the stacktrace about where the NPE occured:

Ahha, I got it. Thanks. The document needs to be updated. It is not obvious to have to generate xmlbean classes separately before running wsgen task.
