Hi All:

I am just trying out examples of entity beans. I am using JBOSS 4.0.0, EJB 2.0, MyEclipse 8.6. Reason for using JBOSS 4.0.0 and EJB 2.0 is just for learning sake. I am reading head first book. In the process help me if I made any mistakes. I wrote a build file using ant to deploy this in deploy directory of JBOSS. I also have login-config.xml, standardjaws.xml and jbosscmp-jdbc.xml file in my Meta-Inf directory. I am getting this error:

java.lang.NullPointerException
at org.jboss.ejb.plugins.local.LocalHomeProxy.invoke(LocalHomeProxy.java:118)
at $Proxy0.findByPrimaryKey(Unknown Source)
at AccesesPackage.DirectorMovie.go(DirectorMovie.java:24)
at AccesesPackage.DirectorMovie.main(DirectorMovie.java:13)

My ejb.jar file:


My Jboss.xml is:



In my director package I have these files:

director home:


director component interface:



director bean:



My movie package has following files:

movie home:



movie component interface:



movie bean:


Finally I have a client class like this:



Any help is greatly appreciated. I get some confidence going by solving this example.

Thank you in advance.
