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:
