Here's an easy way to deal with this situation, without even needing to have your
JSP pages extend a servlet:
* Create a servlet whose init() method creates the connection pool
in the usual way.
* Once the pool is created, store it as an servlet context attribute (which
is the same as an application scope bean in JSP pages):
com.mycompany.mypackage.ConnectionPool myPool =
new ConnectionPool(...);
getServletContext().setAttribute("pool", myPool);
* In the web.xml file, configure this servlet to be loaded at startup time,
so that the connection pool will be established immediately (rather than
on the first request).
* In a JSP page that needs access to the pool, use a <jsp:useBean>
tag like this:
<jsp:useBean id="pool" class="com.mycompany.mypackage.ConnectionPool"
scope="application"/>
