BC4J & Servlets (To DEV TEAM)

Question

Hi all,
I am having problems with using BC4J Application Module with in the servlet. It is working for one concurrent request only. When I try to run for multiple requests (concurrency 5), it was fails to check back the application Modules to pool, once checked out for each request. This is very urgent to us to move this servlet to the production.
1) Suggest us to proper way of using the Application Module in the servlet to handle the multiple requests.
2) Could you suggest any architecture to work Apache Jserv, Servlets, JSP's in a normal Deployment mode.
Please see the Errors Wile doing the load test:
[30/03/2001 17:01:13:114 EST] Servlet: JBO-30004: An application module that was not checked out was checked into the pool, GlobeInvestor_com_globe_invester_stock_InvesterStockAppModule
[30/03/2001 17:01:13:114 EST] : JBO-30004: An application module that was not checked out was checked into the pool, GlobeInvestor_com_globe_invester_stock_InvesterStockAppModule
Thanks,
Suri

Suri,
It's hard to tell what's going on, but the error you're seeing occurs when you try to check an application module back into the wrong pool.
About your concurrency issues: you could be reinstantiating a pool on every request. Make sure you're only using createPool() once - you can use isPoolCreated() to check whether a pool already exists.
