If that's the case, how is Spring getting initialized? Usually you would
configure one of Spring's context listeners, which will take care of
loading the Spring context on startup and destroying it when the
application is shut down / undeployed.
As Ian indicated, you'll need *some* sort of context listener to close
the Spring context (i.e. reverse whatever Spring setup logic you have),
whether it be one of the ones supplied by Spring or your own.

I want to release a database connection while reloading the context (using
Tomcat Manager web app) of a Struts2 Web Application. I am also using Spring

As I am using HSql 'standalone' database, even if the web application
context gets reloaded, the database connection is not released while
destroying the context. So I get 'Database is already in use by other
process' error. I want to know whether there is any way to implement
something like "destroy() method of servlet" in a Struts2 application.
I am not sure whether I can do it with spring configuration. Any idea? If
there are many ways of doing it, kindly also tell which way is the best for
me.
(1) struts.properties:
struts.objectFactory = org.apache.struts2.spring.StrutsSpringObjectFactory
(2) applicationContext.xml (my spring configuration file)
