I have a simple EJB-application. I have deployed the EJB component successfully using J2EE RI. It seems that the lookup of the Home Object is successful. However, when I created a EJB-Object from the Home-object, it generates an exception.
Part of the client code:
try {
System.out.println("1");
Context ic = new InitialContext();
System.out.println("2");
Object o = ic.lookup("Advisor");
System.out.println("3");
AdviceHome home = (AdviceHome) PortableRemoteObject.narrow(o, AdviceHome.class);
System.out.println("4");
if(home==null)
System.out.println("Home is null");
else {
System.out.println("Home is not null");
Advice advisor = home.create();
System.out.println("5");
System.out.println(advisor.getAdvice());
System.out.println("6");
}
} catch(Exception e) {
e.printStackTrace();
}
The result:
1
2
3
4
Home is not null

Do anyone know what problem with my code. I follow the instruction in the book.

I solved the problem finally. Thanks to the author Kathy of "Head First EJB".
For someone having the same problem, try this out:
When you deploy using J2EE RI Deploytool, you need to change the setting first.
Go to the Security Tab under your Bean application.
Then click on the button "Deployment Settings"
Then click the radio button "Support Client Choice".
Then deploy it again.
It works.
