I have installed j2sdk1.4.2_10 and tomcat5.0.28 version.
and set classpath and path variable from the envirmental variable in my computer.
then I deployed the war file of ch02 with tomcat manager, as given in the book of jsp(begging jsp pages).
then I typed in the browser's add bar http://localhost:8080/ch02/example1/index.jsp.
but the it says "The requested resource (/ch02/example1/index.jsp.) is not available."
or the server faced some internal error.

please help me in this problem.

Try with this :

http://localhost:8080/ch02/index.jsp

First:make sure Tomcat has been started up
Second:try the Url="http://localhost:8080/ch02" ,if there are still some
       mistakes,shutdown the Tomcat and startup again.

Like my brother ,I have maken the same wrong.However,I'm not so lucky.
When I used the method suggusted aboved,still I can't solve the question.Is there another method to do it?
