Hi, if you get the solution, could you please share.
Thanks

My Question is "Whether there is any performance issue" ?
Bear Bibeault wrote:There are a number of errors with this code:
Firstly, using scriptlets in a JSP is a poor practice that should have been eradicated years ago. Bad idea.
Secondly, the code assues that the variable exception is not null. This is an invalid assumption. Hence, when it is null, a null pointer exception is raised.

Rajeev roushan sharma wrote:Hey Edward, No need to use session and all in your scenario. If you are using the RequestDispather to forward to your JSP then you will get the same request in your JSP too. so you can simply write request.getParameter("param1") and your are done!
That will not work in his scenario as the data needs to be available across multiple JSPs as per his original post.
You can use the same request querystring with your link..
Edward Manalansan wrote:Here is the sequence..
1. Query string is http....\servlet1?param1=test
2. In servlet1, I store param1 using httpsession, then displays param1 in jsp1(no issues) using Requestdispatcher.
3. Jsp1 uses form action = servlet2, in servlet2 when I issue..
GISAddress gisaddress = (GISAddress) request.getAttribute("gisaddress");
gisaddress.getParam1();
it is null.
I used the same GISAddress in jsp1 and it is working, somehow GISAddress is gettting destroyed prior or when servlet2 is fired.
Thank you.
