Yes, thing about servlet technology is that if you take your time to
understand it, its very powerful on its own... but having said that, there
is one thing you should read up on, that is the whole idea of MVC model with
servlet technology.
There is a guy called marty hall that wrote some More-Servlets-and-JSP
articles... that is the best thing I ever read... just google.
One of the mistakes I made and I think most people coming from ASP will do
it, is try make the whole server in a JSP page.... if you do that you going
to think its a crap technology, but as soon as you learn to use servlets and
jsp together.... its a million times more powerful than ASP. Idea is simply
that you put your logic in the servlet and use the JSP "just" to display
info.
The academics waffle on about seperation of client view and model, but at
its core, thats all it is, and the pivotal tomcat function is something
called getRequestDispatcher.... learn to use it.
After that most of the frameworks just seem to hang bells and whistles on
that idea, like persistance and dbPools which tomcat has anyway.
Then what you will find is that, you can just extract a good idea from any
framework... ok... steal them blind.... ha ha ;)
And this is what I wanted to tell you.... its orgasmic stuff, and the reason
I just luv tomcat... you will start using tomcat for EVERYTHING.
For instance I wanted to write a database replication system, and I started
looking at swing and then thought.... no I'll use tomcat... it runs any
code, and I got a user interface in any browser... so I just use a little
JSP to make the admin functions for the replicator... never going to be a
web app as such....
See wot happens when you get into the MVC thing... magic.
I now run all my apps in Tomcat..... even the Swing apps.... it seems a long
way from the web, until you see someone click on a web page, and a swing app
starts that wasnt even on the machine.... its sitting in Tomcat in another
office.... ha ha.... extreme MVC at work.
In the end you wont even see Tomcat as a servlet web technology... its
becomes the ONLY place to do JAVA.... its dead easy to deploy on, and it
becomes your JAVA OS on any platform.... thats why you'll meet tomcat fans
like me. Any job starts with .... yes... Tomcat.... ha ha

I guess I'm glad I don't use any of that stuff, then ;-D I only have two
different styles in my app: data-entry pages and report pages, so simple
css will probably do just fine.
Thanks!

Yes.... David.... Tomcat is one fancy machine and it also supports tag
libs.
These things are like html tags... just well formed xml.
Struts, Spring and Sun (tomcat frameworks) all have tag libs for just
about everything...
So for example... one can (simplified) type
<html:form blah blah>
and tomcat will stick all the HTML that you would have to write for a
form into your page for you..
and thats wot martin is showing you.... that you can also associate
styles with these fancy things... and if there are errors you can even
associate styles with that.
BUT without the frameworks tomcat is very much plain old HTML...
so you can use it either way....
In the new netbeans you can see where the whole tag thing is going.... in
there you will find a "visual web" designer.... it feels like you using
swing... just drag and drop, set properties, write a little event
code.... etc
If you look at the HTML (JSP) page it makes... its one complex
combination of tag libs, script, CSS and everything else you can think
of.
Thing that is really important to understand is that all these frameworks
are in competition with each other....
Struts competes with Spring who competes with Jboss who competes with
Suns EJB servers.... its chaos.
Now Java Server Faces is suns latest an greatest and you'll see its used
in the Visual designer... and if I'm correct they seem to have left out
struts... now I wonder why ;)
EJB3 some say has stolen good ideas from Spring.... Resin have taken
tomcat and reinvented protocols to make EJB better...
It gives me a huge head-ache!...
So... dont use any framework blindly.... I always try and imagine who is
going to win, and its not always who is the best technology right now.
One thing is for sure.... Basic Tomcat is a winner..... after that, your
guess is as good as mine.
I still like doing it the hard way... HTML, CSS, and a little JSP... now
and then a little XML....
and I steal like crazy from the frameworks.... ha ha.
.... u c.... Tomcat is very very good ;)

David--
I would suggest incorporating style and or styleClass and errorStyle and
or errorStyleClass attributes which derive from supplied CSS
If your thinking MVC (and Struts specifically) I would look at the Tag
documentation available at
http://struts.apache.org/1.x/struts-taglib/tlddoc/html/file.html

Subject: Cascading style sheets and tomcat
Can I use .css files with .jsp's, particularly when they are being
served up by Tomcat 5.5? Or do they only work with static html files?
TIA!
Dave
