java.lang.NullPointerException

[Pawan K Modi, modificado hace 16 años.]

Hello,

I made my portlet to retrieve permissions associated with a defined roleId.
I am calling getPermissions(long) function of class RolePersistenceImpl;

Portlet was available successfully in defined category.

But as soon as i add this portlet i get following error.

Can any one tell me why i am getting this error?
