Java2WSDL error

[Xinjun Chen <xj...@gmail.com>]

I am using Java2WSDL to generate a WSDL from an existing Java file.
My java file is the implementation class of a web service, the code snippet
is as follows:

public class PrimitiveComponent {

public EndpointReferenceType createResource() throws RemoteException {...}
public void initComponentInstance(ComponentInstance instance) throws
RemoteException {...}
public void setRoutingRules(HashMap routingRules) throws RemoteException
{...}
public void setLinkedComponents(LinkedComponents info) throws
RemoteException {...}
public String getStatus() throws RemoteException {...}

}

ComponentInstance is from another jar file, LinkedComponents is a class
containing HashMap and Lists.

When I use the following command to generate WSDL, i get
NullPointerException without any other clue.

*K:\soardsgrid\component\build\classes>java org.apache.axis.wsdl.Java2WSDL-o PC.

Could you expert give me a clue what I should do to successfully generate
the corresponding WSDL file?

Is it necessary that I change all the void input parameter
type and void return type to OperationName and OperationNameResponse complex
type? How can i get more detailed error message?

By the way, I am using Axis 1.2RC2 (distributed with Globus Toolkit Version
4.0.1).
