what does it do when
<load-on-startup>-1</load-on-startup> in the web.xml on a servlet
that is a negative 1
what happens when i have multiple
Servlet 1
<load-on-startup>-1</load-on-startup>
Servlet 2
<load-on-startup>-1</load-on-startup>
http://tomcat.apache.org/tomcat-4.0-doc/catalina/docs/api/org/apache/catalina/Wrapper.html
I think it's container-dependent, but for Tomcat:
getLoadOnStartup
public int getLoadOnStartup()
Return the load-on-startup order value (negative value means load on first call).
load-on-startup is supposed to be supplied with a single, positive number. I think it's ignored if the number is negative, but I'm guessing there. If you had 2 servlets with the same positive load-on-startup value, same 5, it would be up to the container -- the loading order between the two would be undetermined.

Are you asking whether Servlet 1 or Servlet 2 will get loaded?
In the case above, -1 indicates load at first call... so... I would say (like the first responder) whichever one gets called first.
I would assume you have no guarantees...but my experience is that first listed in web.xml gets loaded first. (so if you had two with a load-on-startup of 0 for example--I have usually seen the first in the web.xml start first)
According to OnJava, it's container specific, but I probably wouldn't use the negative value unless you know for certain it will be run only in containers whose behavior you are aware of:
http://www.onjava.com/pub/a/onjava/2001/04/19/tomcat.html?page=4
"The <load-on-startup> sub-element indicates the order in which each servlet should be loaded. Lower positive values are loaded first. If the value is negative or unspecified, then the container can load the servlet at anytime during startup."
thanks for the replies
I am running into a issue that is really weird
so i made the servlet to load with 0 and 1 and the servlets loads on start on my local machine, however when i tried on another server, it does not load any of the servlets....any idea as to why that happens?
both env are Websphere 5.1.1

Some sort of as of yet unidentified configuration and/or deployment problem.
