Re: Re: Re: ConnectionPooling
Thanks Doug,Harry and rest of my friends, After going thru the links ,I was able to make it work.Before I end this thread I just want to clarify some doubts.I am querying a database ,but I have some delay getting back the results.Now I want to check if the query is causing the delay or am I going wrong with allocating connections.So,I want to log all my program steps in a log file,can u just tell me what code I have to add and where?? Would this code help me?? Logger className=org.apache.catalina.logger.FileLogger prefix=localhost_DBTest_log. suffix=.txt timestamp=true/ Looking for these answers and thanks for your generous help. cheers.

Re: Re: Re: ConnectionPooling
http://logging.apache.org/log4j/docs/manual.html You really need to read something like this. Logging is an important step into building an app, so you have to sacrifice now some time for learning how to do it.
