I am trying to develop and deploy a simple web app tutorial given in Head First servlets and jsp book, but after I wrote all the necessary files, when i try to run , it gives me the erro 500 : saying unable to compile jsp file.
I have just 1 servlet(controller), 1 plain java code(model) and 1 jsp file (view). Is there something wrong . I have given all the three files below.

I am using tomcat 5.0

Error is

JSP file


java file (model)

html file (form.html)

please help me..

should i include any jsp jar file from tomcat into classpath variable. i am stuck here..

How are you attempting to run it? How are you compiling it?

i am running it from browser


This form will have a button, which will call the servlet to do some computation and that servlet will call a jsp to give the page to the user....

the servlet class compiled without errors, should i include any classpath for the jsp compilation
