String tto=request.getParameter("to");
String ttitle=request.getParameter("title");
String tcontent=request.getParameter("content");



Properties props=new Properties();//Properties props = System.getProperties();
props.put("mail.smtp.auth","false");
Session s=Session.getInstance(props);//create a new email dialogo according to property

transport.connect("mailhost.shef.ac.uk","","");//log in the email box
transport.sendMessage(message,message.getAllRecipients());//sending email
transport.close();
%>
<div align="center">

<a href="mail.jsp">send another</a> </p>
</div>
<%
}
catch(MessagingException e){
out.println(e.toString());
}
%>

</body>
</html>

This is an example of just one of the pitfalls of putting processing in a JSP instead of a servlet where it belongs. The variable session is used by JSP as a builtin.

Your first step should be to change the processing ste from a JSP to servlet as best practices dictates.
