need help !!

I really feel tired about this problem

I want to develop a web application using apache and tomcat in linux.
when my webapps start, a connection pool servlet will load on startup.

the other servlets in the webapps will use this statement to get a db connection.
"pool = (connectionPool)getServletContext().getAttribute("conpool");"

sometimes this statement will work very well but sometimes it will throws a exception (classCastException: connectionPool)....

help.... why the situation will different everytime?

what is the good way to implement the db connection pool?
is it startup servlet a good method?

thanks
