This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I wish to send control from my Servlet to Jsp.. with some parameters.. however I've tried using sessions but due to perfomace issue I've changed it to POST.... which results in Slow loading of JSP page...
Could you suggest me any other method, in which that can be done.. NOT A FORM POST or setting the variables in session..
Well, during the testing phase.. the process reached.. 60% and after reducing some uncessary parameters...from session to Post... the process reached to 50%... there was 10% difference in the Process fulxtuation.. NOTE: Above was the load testing done for 30 concurrent users on P4 machine with 1GB Ram..
However I've also have to keep in mind that the USER Processing is fast enough.... while using POST action in a servlet...the USER access tends to become bit slow.... and I guess we all know the reasoning for that..
"Yound Devil", My request that you change your display name to adhere to JavaRanch standards was not a suggestion. Valid display names are mandatory for participation on the Ranch. Please change your display name as instructed prior to your next post.
Be aware that accounts with invalid display names are removed.

Jilesh Lakhani I'm a little confused when you talk about Post. When it comes to JSP and Servlets, there are two common things that I can think of that is frequently used. Those are session and request. There are other things like application but I don't bother myself with those since my brain is too small learn all those things. To get back to your problem, have you heard of Expression Language(EL)? Request/session scoped variables can be accessed through them like this:
I'm not too sure what the performance gains are though. Also, to get the attribute in JSP, it's not response.getAttribute(), it's request.setAttribute. Yes, you will need to cast it down to your desired object if you use scriptlets:
Gosh... I'm also getting anxious about how my app would perform once publish on the web... Geeez...
