web application initialization
Hi,
I would like to know if it is possible to have some code called at the web application initialization (something like the init() method of the first servlet called by the web app - which here is ActionServlet).
Should I just extend ActionServlet?
regards,
Fabien

Another thing you can do is use the ServiceManager extension that's
under the contrib
directory in CVS. I've just started to look at it myself. Its seems to
be a fairly
new contributions, so documentation is pretty scarse.

Thank you for the tip, this is definitely working and is not too ugly.
However I still find a little bit stupid we have to create a new Servlet just to use its init method. Or maybe not if your Log4j servlet allows you to modify the logging / the log4j properties remotely (but that is another project, and it is bad not to use struts for that).
I tried just to extend the ActionServlet and rewrite the init method (adding lines to it). After modifying the web.xml, it still did not work. Has anyone a clue why? Did anybody try to extend ActionServlet?

Hi Fabien,
I typically do this in a StartupServlet in my web.xml.
Here is an example of how I initialize Log4j:
<web-app>
<context-param>
<param-name>weblogic.jsp.keepgenerated</param-name>
<param-value>true</param-value>
</context-param>
<servlet>
<servlet-name>log4j</servlet-name>
<servlet-class>com.infogain.DOG.logging.servlet.Log4jServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>2</param-value>
</init-param>
<init-param>
<param-name>wlpi_log4j_conf</param-name>
<param-value>/WEB-INF/wlpi_log4j_conf.properties</param-value>
</init-param>
<init-param>
<param-name>base_category</param-name>
<param-value>com.infogain.DOG</param-value>
</init-param>
<init-param>
<param-name>base_priority</param-name>
<param-value>info</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
...
The init() method of Log4jServlet handles stuff that needs to run before
Struts (struts's <load-on-startup> is 2).
