Nilesh,
If u define variable as
<%
String scope="request";
%>
then it's scope is for request.
and if u define it as
<%!
String scope="Application";
%>
Then this variable is aval till jsp is in memory

Hi Nilesh,
You need to learn a bit.. Better say this way

  <%
    String variable="something";
  %>

The above variable behaves as a local variable, as it will be
available inside the [B]service()[b] method. You wont
be able to access this variable if you have declared a method
in JSP. where as...

  <%! 
   String variable="something";
  %>

In this case, the variable behaves as a member variable. It will be
available thruout the JSP, and even you can access this variable
in any of you method defined in JSP. It has scope in the JSP in
which it is declared as well as in in the static include files i.e.
include using

<@include > and <jsp:include> 

but not
available to dynamic include i.e.

<jsp:include>[code].
  A method in JSP can be defined defined using [CODE]<%!     %>

.

I hope this clears the doubt.

Welcome to the Ranch Java Brewer!
You'll find that there aren't many rules you'll have to worry about, but one is that proper names are required. And while yours passes the format check, it fails in the 'obviously fictitious' category. Please take a look at the JavaRanch Naming Policy and change your display name to match it.
Thanks!
