Automatically instantiate Servlet
Hi, usually Tomcat Servlets are instanciated after a webapplication is accessing its url first time. Is there a method of automatically do this? Can I tell Tomcat to instanciate a servlet directly after startup using a config file (web.xml, server.xml)? If the answer is yes, can anybody provide an example?

RE: Automatically instantiate Servlet
Ralf, web.xml is the right place. You just have to put another entry in your desired servlet.../servlet section: servlet [...] load-on-startup1/load-on-startup /servlet The number specified determines the order the servlets are instantiated at startup (if you instantiante more than one).

Re: Automatically instantiate Servlet
Check out the load-on-startup tag in we.xml. The documentation can explain it much better than I. servlet servlet-namemyServ/servlet-name servlet-classcom.myaddress.myapp.HelloServlet/servlet-class load-on-startup1/load-on-startup /servlet Andoni. - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, November 18, 2003 3:59 PM Subject: Automatically instantiate Servlet Hi, usually Tomcat Servlets are instanciated after a webapplication is accessing its url first time.

Re: Automatically instantiate Servlet
Hi, thank you very much. It works. What do the 1 mean? Is it just a binary value 0 = off 1 = on ??

Re: Automatically instantiate Servlet
The one is the order in which you want numbered servlets to start up. Non-numbered servlets don't start until called.

RE: Automatically instantiate Servlet
No, it's a numeric value giving the start priority to define the order if you have more than one servlet to start. (The servlets are started in ascending order of this value) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 18, 2003 5:23 PM To: Tomcat Users List Subject: Re: Automatically instantiate Servlet What do the 1 mean?

RE: Automatically instantiate Servlet
Howdy, Although be careful of depending on the order. It's undefined if there are multiple servlets with the same load-on-startup number, and negative values are permissible as well.

RE: Automatically instantiate Servlet
Just one addition from the spec (2.4 pfd3): 'If the value is a negative integer, or the element is not present, the container is free to load the servlet whenever it chooses.' So what I said (wrote) is just true from zero on. -Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 18, 2003 5:40 PM To: Tomcat Users List Subject: RE: Automatically instantiate Servlet Although be careful of depending on the order.
