listener load order

[Virtual Light <vi...@hotmail.com>]

I have a listener that I have added to my web.xml file that needs to load before my webservice servlet is loaded.  My understanding was that web.xml is processed in the order in which the entries are made.  The listener is the first thing in this file yet it appears to be being processed after the servlet which I have added a load on startup param of 2 to see if this would make a difference.  Is there some trick that I have missed here?  An entry in the geronimo web.xml file?  Some other way to force the listener to load first?

Regards,
Bill

David thanks for the the reply. I am using geronimo 2.0 with Tomcat 6 all of which are part of Websphere Community edition.  The web service servlet is being loaded first as the init method is being called and the configurations parameters that would be there if the listener had loaded first are null.  I verified this by removing the listener from my web.xml file and calling the initialize method of this software from within the init method of my webservice which produced the expected results.  Calling the initialize method directly is not the preffered way to start this software up but it does provide me a temporary work around.

Bill

I don't think you can ever rely on that behavior.  For instance the load-on-startup for servlets definitely can contradict the order.

In our jetty implementation we have code that should be loading all the listeners before any servlets or filters.  I would expect tomcat would load all the listeners before anything else, and AFAIK spring apps depend on this behavior.  Knowing which geronimo version and which web container you are using might help to track down the problem.
How do you determine that the listener is created after the servlet?
