setting application variables
Hi, I'm very new to Tomcat and JSP. Can anybody tell me how I can initialize some application variables from a file so that they are available to all of the asp pages in my application as soon as it starts? Thanks!
RE: setting application variables
You could have a ContextListener for your web application. You could then read the properties from your property file and put them in the application context so that all your JSP pages have access to them. In order to implement a ContextListener you need to write a class that implements the ServletContextListener interface. You will have to make an entry in your web.xml about the same. Hope this helps, Mufaddal. -Original Message- From: Josh Howe [mailto:[EMAIL PROTECTED] Sent: Friday, July 29, 2005 1:14 PM To: tomcat-user@jakarta.apache.org Subject: setting application variables Hi, I'm very new to Tomcat and JSP.

Re: setting application variables
I can even save you some time: http://javawebparts.sourceforge.net There you will find an AppConfigListener that I think will do the trick nicely for you.

Re: setting application variables
Look up context init-params and servlet init-params. I have some demo apps that demonstrate the use of these: http://simple.souther.us On Fri, 2005-07-29 at 16:14, Josh Howe wrote: Hi, I'm very new to Tomcat and JSP.
