Hi All,
I m very new to OpenEJB..wanted to run a EJB project in Tomcat..Using
Eclipse neon as IDE,Tomcat 6and JDK7.
I am successfully done with installation of openejb.war in tomcat/webApps
directory and have done automatic installation of listner class and
javaagent to tomcat.
I have created a Dynamic web project named TestEJB in eclipse having session
beans, calling it from servlet(TestServlet).using Hibernate as
JPAimplementation.
After adding a instance of tomcat server and started it.
Its started with..Error in console
*NO Listener found for openEJB.*
java.lang.NullPointerException

as
http://localhost:8080/TestEJB/TestServlet getting exception
Inside servlet i am injecting sessionbean as
@EJB
private UserService userService;
