Re: Question about Tomcat context
First a few questions;
What does the app do
Do the deployed applications differ
What is the reason you want them separate
Do they share anything, reaml,db,files,....
Do you need to be able to update them easily (all in one go)
How do you intend to deploy them, war, copy, remote
Is it an option to upgrade to Tomcat 6.0
That said:
By simply copying the same files to different contexts you have the same
application available multiple times under different URLs.

Hi Jerome.
If you save everything that is specific to the context in that context, they
operate as separate.

Re: Question about Tomcat context

Hi, Thanks for quick answers
My app is a Cms
The sources, wars, deploy method is the same.
Only a "Environement String" (pointing to a specific config dir) is différent with Context.
I don't want to they share anything at all, because is not same customers for each context.
So for security reason, i don't want to share (even i loose memory and space).
My customers don't have access to tomcat at all (except the app off course).
I will deploy, upgrade, remove, etc.. so if easyer it's better, but i don't really care about that.
I have already separate context for previous version of my app.
But i'm (was) not sure for sharing "rules" of tomcat in Singleton or Hibernate case.
(Because the goal of a singleton by definition is to have unique instance)
I was affraid in test, who i have see my Log4J logs in wrong directory (maybe it's because is in "common/lib" dir)
So if i understand well, if the library(s) is not in "common/lib" but in "WEB-INF/lib" they don't share context ?
Thanks again for your time and answers..
