Cannot find WSDL2Java Class

[Jinghua Gu]

I can get http://localhost:8080/axis/services/MyService?wsdl WSDL from web browser

but the following command didn't work.

% java org.apache.axis.wsdl.WSDL2Java http://localhost:8080/axis/services/MyService?wsdl

Any idea on where to run this command? It always complains that
the java.lang.NoClassDefFoundError: org/apache/axis/wsdl/WSDL2Java.

It cannot find the class. I cannot neither.

Thanks,
Emily
