I've done it exactly the same way you described and I still have the same
problem....

the idea is to have one <jsp/html> introductory display file for your webappthe
introductory display file is configured via welcome-file directive so edit the
web.xml from your webapp install folder
assuming the name of your webapp is 'practica3'
$CATALINA_HOME/webapps/practica3/WEB-INF/practica3/web.xml immediately after
<webapp>
<welcome-file-list> <welcome-file> login.html
</welcome-file> </welcome-file-list>
alsoplace the login.html in the webapp folder you should have
copy login.html $CATALINA_HOME/webapps/practica3/login.htmlonce the browser
client files are in place we can start to concentrate on the taglibs (jstl or
struts) and then the controller code..Martin--

In that case you're dealing with a flawed architecture as you have no input
mechamismyour web.xml should contain at least 1 welcome display file such as
this input declaration in web.xml
<welcome-file-list> <welcome-file> Login.html
</welcome-file> </welcome-file-list>Good LuckM--

I don't use jsp. I use html pages for static content and .view pages for
dynamic content.If you want to see the aplication you have to deploy a .war
archive in tomcatThe .view pages get data from a servletrequest (through the
framework, wich I don't have access to it), present static content and send
requests to the controller (detailed in the controller.xml) wich interactuates
with the model (MailMessageSession.java and all the DAO's classes and JDBC)

Hi again, by a problem with hotmail I have only been sending messages with one
person. I'll put it all again with a rar that is all my project. Hi!I'm
studying at the university an assignature based on web applications
developement using java servlets, tomcat, Model-view-controller, and a
framework done by my teacher that is a simplification of struts (we use his
.jar to implement all te classes of his framework and he has told us that
everything is correct and that we cannot modify his classes). He has invented a
language called VIEW.The dynamic pages terminate with the sufix .view What I'm
doing is a web application that has some users(with passwords) in a postgresql
database (here everything correct) and that they login and send/receive
messages to/from the rest of the users.I'm also using eclipse, so everything is
well compilatedWhen a user logins, tomcat sends me an exception and doesn't
shows the main dynamic page where the logged user views recieved messages and
can send messages to other users.I give you the code of the mail.view page:

the problem is at:<b:set var='srv'
value='${request.session.getAttribute('message_srv')}'/> can somebody help me??
Oh! and the tomcat exception:Estado HTTP 500 -
