The error above is for using the 4.0.4RC1 installer directly.

This time I downloaded the JBoss 4.0.4RC1 zip file. Unzip the zip file.
Downloaded the EJB3.
Installed EJB3 into the JBoss according to the instruction.

I can start JBoss without any error.
But I got error when I deployed my web application.

ObjectName: jboss.j2ee:service=EJB3,ear=emp.ear,jar=emp.ejb3,name=EmployeeManagerBean
State: NOTYETINSTALLED
I Depend On:
persistence.units:unitName=emp

--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: persistence.units:unitName=emp
State: NOTYETINSTALLED

At runtime the session bean not found.

InitialContext ctx = new InitialContext();
ctx.lookup(EmployeeManager.getName());

will throw NameNotFoundException.


public class EmployeeManagerBean implements EmployeeManager {
@PersistenceContext (unitName="emp")
protected EntityManager em;
...

}

The web application runs well with JBoss 4.0.3SP1.

Did I miss anything?

Thanks for help.
