[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - Are RMI Stubs in JNDI Thread-safe?

[micho]

I have a servlet talking to a Sessionbean.

Is it allowed -regarding threadsafeness - to obtain the manager in the servlets init() method and store it in an instance-membervariable of the servlet.

public class LzServlet extends HttpServlet {
  | 
  |   MandantenManager mm =null;
  |   
  |   public void init(ServletConfig config)
  |   { 
  |     try
  |     { InitialContext ctx = new InitialContext();
  |       mm = (MandantenManager) ctx.lookup("BBCS/MandantenManagerBean/remote");
  |     }
  |     catch (Exception e)
  |     { e.printStackTrace(); }
  |   }	
  | 

If it is not allowed, is there a performant way to solve the problem, without creating an initialContext in every call of the servelet.

Is getting the initialcontext and the lookup an "expensive" operation?
