load-on-startup doesn't work

[Aleksi Kallio]

I have a servlet that starts up my application when Orion (1.0.3 - yes, a very old 
one) is started. The problem is that nothing happens - init(ServletContext) doesn't 
get called. I have this in global-web-application.xml:

<servlet>
    <servlet-name>Software</servlet-name>
    <display-name>Software</display-name>
    <servlet-class>foo.bar.Software</servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
        <param-name>application-directory</param-name>
        <param-value>applications/software</param-value>
    </init-param>
</servlet>           

What could be the problem? Any suggestions how to debug this? I don't have any clues...
