About java.lang.InstantiationException.

[Bi...@idx.com]

Hi,

I created a Java interface and several Java classes which implement the 
interface. I used Java2WSDL to generate the WSDL from the interface. Then 
I used WSDL2Java to generate the stub classes.

When I used the stub classes, I got the following error:

AxisFault
 faultCode: 
{http://schemas.xmlsoap.org/soap/envelope/}Server.userException
 faultSubcode: 
 faultString: java.lang.InstantiationException: 
com.idx.lw.webservices.inbox.InboxRetrievalService
 faultActor: null
 faultNode: null
 faultDetail: 
        stackTrace: java.lang.InstantiationException: 
com.idx.lw.webservices.inbox.InboxRetrievalService

This seems to me that the Axis tried to create an object based on the 
interface, not based on one of my implementation classes.

I am wondering what I am doing wrong and how to fix it here? Or we just 
can't use an interface for the web service directly, i.e., dynamic 
invocation not supported.

Thanks!

Bing

Hi Bing!

Could you be a little more specific? What were the names of your interface
and your implementation classes? What options did you use when running
java2wsdl and wsdl2java? How did you "use" the stub classes?
