Using filter

I want to use a servlet for application start up say,StartupListener which extends HttpServlet to initialise the session factory and an ActionFilter to get the session from thread local and pass it to the action class. I specify the following in my web.xml file. I find that if I specify the action filter in web.xml as shown the init method in StartuoListener is not read. Is this the way to configure web.xml when both filter and servlet is used.
<filter>
<filter-name>actionFilter</filter-name>
<filter-class>com.softex.eg.web.filter.ActionFilter</filter-class>
</filter>


<servlet>
<servlet-name>StartupListener</servlet-name>
<servlet-class>com.softex.eg.web.listener.StartupListener</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

Your configuration is OK. What exactly is your problem?

You need to specify the filter mapping like the following:

Code:

   <filter>
      <filter-name>PersistenceFilter</filter-name>
      <filter-class>com.jadecove.util.Persistence</filter-class>
   </filter>
   
   <filter-mapping>
      <filter-name>PersistenceFilter</filter-name>
      <url-pattern>*.do</url-pattern>
   </filter-mapping>
  
   <filter-mapping>
      <filter-name>PersistenceFilter</filter-name>
      <url-pattern>*.jsp</url-pattern>
   </filter-mapping>
