Please help, i am totally new to JBoss, thank you

I have installed the JBoss/Tomcat,
I make 'temp.war' dir under deploy and 'WEB-INT' dir under temp

it is totally ok if i put a html file in temp.war and
display it with http://localhost:8080/temp/file.html

but after i change the file.html to file.jsp,

the error message 'Apache Tomcat/4.0.3 - HTTP Status 500 - Internal Server Error' occur, why?
