[jboss-user] [EJB 3.0] - classcastexception on redeploy

[Bart1985]

Hello,

I am relatively new to EJB3.0 and I am currently developing session and entity beans for a new application.

I'm using Jboss-4.0.5 and when I deploy the first time and I use a standalone application to test my sessionbeans, everything works fine. But when I redeploy my .jar application and use that standalone application again to invoke a sessionbean that passes a remote interface of another sessionbean, I get a classcastexception on PortableRemoteObject.narrow in the standalone application!

This is the remote interface that I invoke to get another sessionbeans remote interface:

@Remote
public interface PermissionRemote

{
  public SchoolsRemote getSchoolsBean();//UserlogRemote ulr);
}

And then the interface that causes the classcastexception:

@Remote
public interface SchoolsRemote
{
  public boolean subscribeSchool(String adminFullName, 
                                 String adminUserName,
                                 String adminEmail,
                                 String adminPhoneNumber,
                                 String adminPassword,
                                 String schoolName);  
  //public School  findSchool(int pKey);
  public String  sayHi();
}

The JBoss error:
