Is it possible to load a servlet on the standalone server startup?

[brownie]

I need to write JUnit tests for an existing project. There are some servlets that should be loaded to initialize some stuff.
Is it possible to load a servlet on the standalone server startup, e.g. using Jetty?

Thanks in advance.

I'm not sure about the servlet, but if you're using OpenEJB 3.1.2 you
can use the @Startup annotation on a Singleton EJB to do the
initialization. You can also make such a bean only available in your
tests, so initialization for tests happen through this and in
production through the servlet. Delegating this to a dedicated
Initialize class/object would centralize the code.

Hi,

not sure it's the better mailing list t talk about Servlet.
Never mind, to specify a load order, you can try something like
    <servlet>
    <servlet-name>Servlet name</servlet-name>
    <display-name>Display name</display-name>
    <servlet-class>XXXServlet</servlet-class>
    <load-on-startup>0</load-on-startup>
    </servlet>

<load-on-startup>0</load-on-startup> indicates that the servlet won't be started until a request tries to access it.

If load-on-startup is greater than zero then when the container starts it will start that servlet in ascending order of the load on startup value you put there (ie 1 then 2 then 5 then 10 and so on).

IMO, it would be better to use a servlet listener and implement the contextInitialized method.

Hope it helps.
