I'm having trouble obtaining a reference to an EJB entity bean in a portlet.
The entity bean has successfully deployed and I've confirmed the JNDI name in
the jmx-console (PersonBean).
I had first tried to obtain the reference through the EJB annotation, injecting
it into the portlet as such:
| public class ModifyPerson extends GenericPortlet {
| @EJB(name="PersonBean")
| private PersonLocal bean;
| .
| .
| .
| }
|
(PersonLocal is the local interface)
However, this did not appear to work as I got a NullPointerException when I
tried to call any of its methods.
When that faied, I tried to do a JNDI lookup in the init() method:
| public void inti() throws PortletException{
| try{
| InitialContext ctx = new InitialContext();
| bean = (PersonLocal) ctx.lookup("java:/env/comp/PersonBean");
| }catch(NamingException ex){
| throw new PortletException(ex.getMessage());
| }
| }
|
The portlet instance did not appear to have thrown any exceptions when
initializing, which I had thought was promising, but when I try to call any of
the bean's methods, I still get the NullPointerException.
I am assuming this NullPointerException is the result of bean remaining as a
null value as an actual reference to the bean is not obtained.
Any help in this matter will be greatly appreciated.
