Inject an EJB 3.0 into the init() Method of a Servlet

This tip shows you how to inject an EJB 3.0 into the init() method of a servlet.

//place all the required imports here
import package.to.EJB.interface.myInterface;

public class EJB30Servlet extends HttpServlet {

@EJB
myInterface myobj;

public void init(ServletConfig config) throws ServletException {
  super.init(config);
  try {
      //get the inital context
      Context ctx = new InitialContext();
            
      myobj=(myInterface) ctx.lookup(myInterface.class.getName());  
      } catch (Exception e) {  e.printStackTrace(); }      
    }
Now you can call the EJB methods through the myobj object!
