Re: [Java] Common init params in app web.xml

i don't have much experience with tomcat, but from what i can gather:
1. init params shud be servlet specific!! and this is true for most other
servlet engines too!!
2. but why do u really need to change the web.xml file so often??? and
anyway it does not take long to restart tomcat!!
3.i havent tried enhydra's servlet engine, but i have use Unify e-wave
ServletExec, and i found that it is much more usable than tomcat. though
this particullar servlet engine is not freeware or open source.

now i have some questions too (for tomcat!):
1.how can i make servlets read an external file (i need to access files for
things like templates, etc)
2.how can i enable session management for my servlets using url rewriting??
and change the name of the session variable!

> 1. Is it possible in some way to have common init-params in the web.xml
file in a particular web-app. I am speaking in the  context of Tomcat. From
what I read in the DTD, there is no common Init-params, only servlet

on changing.I know, one should plan in advance, but sometimes you can't help
it. In such case is it possible for getting Tomcat to reread the web-app
without being restarted?

vis-a-vis Tomcat?
