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 compilated When 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: <?xml version="1.0" encoding="ISO-8859-1"?> <v:view xmlns:v="http://soft0.upc.es:8080/web/NS/webfw/view"; xmlns:b="/base.vlib" component-element-prefixes="b"><HTML><HEAD> <TITLE>Disseny d'aplicacions WEB: P3</TITLE> <LINk rel="stylesheet" href="styles.css" type="text/css"/></HEAD><BODY><center><table width="700" border="0" cellspacing="0" cellpadding="0"><tr><td><br/> <b:set var="srv" value="${request.session.getAttribute('message_srv')}"/> <b:if test="${not srv}"> <h1>ERROR</h1> <p><span style="color: #FF0000;">Session Error</span></p> <hr color="#1E90FF"/> <a HREF="index.html">Volver</a></b:if> <b:if test="${srv}"> <H1>${srv.userName}</H1> <hr color="#1E90FF"/> <b:set var="recmess" value="${srv.receivedMessages()}"/><b:if test="${not recmess}"> <H2>No hay mensajes recibidos</H2></b:if> <b:if test="${recmess}"> <H2>Mensajes recibidos:</H2> <FORM METHOD="POST" ACTION="delete.do"> <!-- Lista de mensajes --> <table border="2" style="border-color: #1E90FF" cellspacing="1" align="center"> <tr> <td><font>remitente</font></td> <td><font>mensaje</font></td> <td><font>fecha</font></td> <td><font>eliminar</font></td> </tr> <b:for-each var="message" items="${srv.receivedMessages()}"><tr><td>${message.from}</td><td><pre>${mes sage.text}</pre></td><td><pre>${message.date}</pre></td><td><input type="checkbox" name="message_id" value="${message.id}"/></td></tr></b:for-each> </table> <p><INPUT TYPE="submit" NAME="delete" VALUE="Eliminar"/></p> </FORM></b:if> <hr color="#1E90FF"/> <FORM METHOD="POST" ACTION="send.do"><font>Destinatario/s:</font><br/><select name="receiver" multiple="multiple"> <b:for-each var="user" items="${srv.userListToSend()}"> <option value="${user.name}">${user.name}</option>"</b:for-each> </select><br/><font>Mensaje:</font> <p><TEXTAREA NAME="message" ROWS="10" COLS="100"></TEXTAREA></p> <p><INPUT TYPE="submit" NAME="send" VALUE="Enviar"/></p> </FORM> <hr color="#1E90FF"/> <FORM METHOD="POST" ACTION="logout.do"> <p><INPUT TYPE="submit" VALUE="Logout"/></p> </FORM></b:if> </td></tr></table></center></BODY></HTML></v:view> I think that the problem is at: <b:set var="srv" value="${request.session.getAttribute('message_srv')}"/> can somebody help me??
