Re: How can i call a servlet method from another servlet

[Mahendra Yadav (CTS)]

Ernie,
I did
the same thing as described here but the CallableServlet should be invoked at
least once so that its init() may be called. The Class.forName() doesn't help
here, as loading doesn't lead to the call of init() without a client request
associated with the loading(my understanding).
    When I send a request for the
CallableServlet first and then try getting the reference of it in other servlet
tru the path described here, the things works perfectly.
 
Can't
I do without calling the CallableServlet first.
 
Regards
 
Mahendra

from another servlet, you need to get a reference to the servlet that you want
to call by using the ServletContext. The servlet that you want to call from
other servlets must put a reference to itself in the servlet context. Use
getAttribute() and getAttribute() methods to accomplish this.
This is usually done in the init() method of the callable servlet:
 public void init(ServletConfig cfg) throws ServletException
 {   super.init(cfg);   // Add
this servlet to the context  
getServletContext().setAttribute("callableServlet", this);
 }
Then put this in the calling servlet:
CallableServlet cs =    
(CallableServlet)getServletContext().getAttribute("callableServlet");
Now you can use the reference "cs" to invoke methods in the callable
servlet.
