Where to put initialization code
I want to know where I can do some initialization for the web-application.
Before I used Tapestry I used the following code to do some initialization
(like starting the connection broker and loggers). This initialization code
cannot be put in the Visit Object.
Is there another way of doing the initialization or do I have to use the
same code in Tapestry?
<code>
web.xml:
<listener>
<listener-class>semantica.docsdb.dat.Dat</listener-class>
</listener>
*****************************************************************
public final class Dat implements ServletContextListener {
public void contextInitialized(ServletContextEvent event) {
/* Initialization code here */
}
}
</code>

I think the right way is the Global object constructor

You could create your own subclass of the Application Servlet
(org.apache.tapestry.ApplicationServlet) and override the init method.
In your web.xml you would have to change the servlet mapping for
tapestry to something like this:
<servlet>
<servlet-name>Servlet name</servlet-name>
<servlet-class>org.mypackage.MyApplicationServlet</servlet-class>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Servlet name</servlet-name>
<url-pattern>/app</url-pattern>
</servlet-mapping>
