Exception while creating a jar file for session bean

[Rishi Upadhyay]

Hi,
I am getting the following exception when I try to create a jar file for a session bean.I have created around 10 entity bean jar files using ejbdeployer tool and everything worked fine.They were also deployed without any error.Now suddenly when I try to do the same thing for session bean it throws me this exception.I am confused!!
The 3 classes(remote+bean+home) for the session bean are located in package structure like com.sam.session.I use a helper class which is in com.sam.helper.
I am using weblogic 5.1(evaluation copy) and structurebuilder to develop the beans(both entity and session).
I would appreciate any help from this forum.I know somebody else has also posted similar question but there is no reply in it.

Look at the definition of your home and bean interfaces (or post them here) - I've seen this happen when the definitions of the two do not match.

I could create a jar file and deploy my session bean using Structure Builder and Deployment Builder.So I am fine for the time being,but I would still like to know what is wrong with ejbdeployer or my deployment,whichever is the case.I am posting the method signatures of remote,home and bean:
UserAdminSession:

public interface UserAdminSession extends EJBObject
{
public boolean createRoles(RolesInfo rolesInfo) throws RemoteException;
public RolesInfo readRoles(long ro_roleid) throws RemoteException;
public boolean updateRoles(RolesInfo rolesInfo) throws RemoteException;
}

UserAdminSessionHome:

package com.sam.session;
import javax.ejb.EJBHome;

Hi,
you have the sam question as Ho An, I reply his question with code, pls refer to it. I suggest that you write a cmd file if you use winNT. In this cmd file, set path, compile bean/home/interface/helperclass, zip java class into one jar file,deploy them, run client. I found it very convinient, works for any kind of beans( of couse you need do some modification for each bean).
Good luck.
