About load-on-startup tag in web.xml in tomcat

[ramakrishna]

Hi All,
I would like to start a servlet independent of first
request.That y iam using load-on-startup tag in web.xml i.e
<load-on-startup>0</load-on-startup>.

My Requirement is when ever tomcat server starts it should load
the all the servlets independent of the first request to that servlets.

Iam using tomcat 4.0. It is not loading servlets when server is
started.

i.e Is there any element in need to set in server.xml to load
the servlets when server is started.

Thanks In Advance.

AFAIK, the load-on-startup tag only specifies the relative order of startup
of the various servlets; they do not force the servlets to startup when the
container does.

There is a listener tag you can use -- this gets webapp startup and shutdown
events. This isn't a servlet, but is part of the servlet spec. The timing of
these events is, perhaps, not strictly specified: it is not "as soon as
Tomcat starts up" but "before any request is passed to the webapp."
Depending on your needs, this may be good enough.
