well other way is use the request scope, you can call the value as the request.variablename = thevalue you wanna call>
request scope is avaliable to whole application and it can be used where u neeed it, it will get changed once u overwrite the other value in the same request.variablename
it does persist the value like appplication!
for me u can use request scope,
other options are already provided to u by other experts!
