This warning is coming as you might be using Jdk 1.4 version.When executing the JSP for the first time, the engine will first convert the JSP into source code for a servlet and then, (if the engine is written for JDK 1.3), will use sun.tools.javac.Main in order to compile the generated servlet,but code.sun.tools.javac.Main has been deprecated in jdk1.4 so you will have to use appropriate servlet engine (for jdk1.4) or bring back the jdk1.3 version. The error, again, seems to be due to some version mis-match as logic seems to be perfect.Try to checkout the javax.servlet.http.HttpSession.class from ur jar, though that is bit tedious, to see if it contains the method set/getAttribute. -Varun [ January 08, 2003: Message edited by: varun Khanna ]
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
