Dear Sir,
In the UserAuthenticationServlet.java file i am setting the
cmpValue 0.
But when i am trying to get the value in jsp why the cmpvalue display
the null instead of 0 value.
cmpValue = (String)session.getAttribute("cmpValue");
out.println("cmpValue"+cmpValue); //null instead of 0 value.

Could please rectify my code so that i will getting the 0 value.

UserAuthenticationServlet.java
int myInt=0;
session.setAttribute("cmpValue", new Integer(myInt));

x.jsp
cmpValue = (String)session.getAttribute("cmpValue");
out.println("cmpValue"+cmpValue);

Thanks and Regards

How you get that session object in servlet , I'm interested to How you create the session object in Servlet .

It may be the case that , the session you are accessing on JSP page is different from one that you created on Servlet ..
