This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
our website is fameboxx.com. its up and a social networking site with a no.of modules(19 modules) having many tables(116 tables) and a single database.
the website gets down time to time at very short intervals. we want to get rid of this problem ASAP.
the server guys say, there is some problem in code.they are saying that mysql connections are not properly closed. while its not true. we have closed the connections on each pages and reopen when they need.
i m in great trouble , please help !
thanks in advance !!!
P.S. You should be user container-managed connection pooling. Manually managing the connectionz is almost always a recipe for disaster.

i can tell you tomorrow the correct version of the tomcat we are using,.
one thing more .. i m using a connection object on every page and closing the connection properly after page seizes to exist. for this i have made a simpe java program for connection and put its compiled(class file ) in classes directory of WEB-INF . i just create object of this class for establishing the connection. And while i know java does garbage collection for the objects used on a page when it gets unused further( when we switch from one page to another),,,, i have manually nullified each of the objects used on the page..
Thus i have done my best to overcome such saturation i m suffering with..
And most importantly as sever gets down and we make it restart by requesting from sever guys for it.. it gets well and behaves as it was never down. i mean , then it stats working very good.. but after some time .. it gets down again. thanks again of your responses .. please help me by your further suggestion .and as you said we should use the connection pooling . please guide about connection pooling in java n provide the code for the connection pooling in java .. i would be very graceful to you.
