WSDL2Java in Axis2 is not working?

[Bruno Negrao]

Hi Guys,

I'm a newbie and I'm trying to generate java code for the example wsdl
attached to this email. I'm using the wsdl2java from the
axis2-std-SNAPSHOT-bin.zip package.
After execution I receive the following errors:

Exception in thread "main"

Is this a bug in wsdl2java

Thank you,
