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 class.

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(); }
 }
