Subject Re: Tomcat 4.0
Date Wed, 31 Jul 2002 16:04:55 GMT
There are not very involved since they should use another servlet container, even an
application server. 
We have many of our customers using Tomcat 3.2.4 but some use Websphere, other WebLogic ...
Our product work on tomcat we have our own Servlets and taglib delivered in WEB-INF/lib/ of
our demos applications, we have configuration files in a subdirectory  of the conf directory.
There are some properties file for jndi access. Our product can be customized. This customization
is on the properties file but also on jsps and servlets we deliver.
For example we can have the customer can change an init-param for a servlet and he could also
want to modify a Jsp page by adding custom tags.
This customization the customer can do it anytime. But if he wants to port his customized
application to another server we don't want him to use some jsp 1.2 specific features like
using JSTL in our jsp since most of products are not jsp 1.2 compatible.
The fact is that i want to migrate my taglib to jsp 1.2 compatible and i don't want to write
(and support) it for both jsp 1.1 and jsp 1.2 server. We want a smooth migration ..
