The example application defines a custom plug-in that is initialised at
start-up and loads the database and stores it in the ServletContext
(application scope).
struts-config.xml:
<plug-in
className="org.apache.struts.webapp.example.memory.MemoryDatabasePlugIn">
<set-property property="pathname" value="/WEB-INF/database.xml"/>
</plug-in>
MemoryDatabasePlugIn.java
servlet.getServletContext().setAttribute(Constants.DATABASE_KEY,
database);
Constants.java
public static final String DATABASE_KEY = "database";
Plug-ins are a common way to initialise application resources. Another way,
that requires at least a Servlet 2.3 container would be to implement a
ServletContextListener.
