how to make a servlet to run at startup of the application

[Mohamed Alatroush]

add this to the servlet definition at web.xml

<load-on-startup>1</load-on-startup>


for eg

<servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>servlet.MyServlet</servlet-class>

<load-on-startup>1</load-on-startup>
</servlet>

true, but take care of the "load-on-startup" parameter.
it can depend the kind of server you are deploying on.

sun servers and websphere CAN use different numbers.
i remember at the time that on the sun server it had to be "-1" or it didn't work.
Don't know about tomcat itself. also 1 i supose.

Why do you need to do this? If you are using a servlet to try and perform initialization for the web app, that's the wrong approach.

Rather, a context listener should be used.

What do you mean by saying "make a servlet to run"?
Does it mean the one of the Servlet's HTTP methods (POST, GET) get called?
