How to run client for EJB3,

[Ram Venkat]

Hi ,

I am very new to EJB3, configure following environment.
JAVA_HOME=java 5.0
J2EE_HOME=j2ee 1.5
Application server = glassfish,
BOOK = EJB3 IN ACTION


i successfully deplyed ear file (contails Interface ,bean class),
i written simple client with main method. looks like following

@EJB
RemoteInt remote = null;
p s v m(){
remote.display();
}

i am getting NullPointerException,


What are the class/jar files in need to place in CLASSPATH


Thanks

NullPointer exceptions are insanely common, you might want to be a tad more specific. Also consult glassfish tutorials for getting started with glassfish.

[Bill Shirley]

particularly, give the exact copy/pasted code (or a snippet), and the exact output, and

use the CODE tags

Finally i found solution for this problem



@EJB
RemoteInt remote = null; It's creating problem because it's assigned to null;
p s v m(){
remote.display();
}

i changed to above code to
@EJB
[B]RemoteInt remote;

It's working now.

but can any one give explanation on this.
