Encountered java.lang.reflect.InvocationTargetException

[weng daiyue <da...@hotmail.com>]

Hi, I am using tomcat to deploy a business registry service, and I use APIs 
provided by uddi4j to interact with UDDI, and I encounter the following 
problem: 

AxisFault 
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException 
faultSubcode: 
faultString: java.lang.reflect.InvocationTargetException 
faultActor: 
faultNode: 
faultDetail:

                return returnedBusinessEntity.getBusinessKey(); 
       } 
} 


I think the problem probably exists in proxy.save_business() method, and I 
don't know how to solve it, so does anyone know how to resolve my problem? 
This exception has annoyed me for days, thanks advance.
