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:
