Java EE (Java Enterprise Edition) General Discussion

I am using Apache Tomcat 4.1.31 and have JDK 1.4.

The default JSP and servlet examples that come with Tomcat are running,
but the problem is my own applications are not running. I have kept the application in the webapps directory but when I enter the URL for example for an application named 'myapp' saved in the webapps/myapp directory I get an error page displaying the following error message:

HTTP Status 404 - myapp/filename type Status report

message myapp/index.jsp
description The requested resource (myapp/filename) is not available.

Apache Tomcat/4.1.27

the examples folder and myapp folder is in the same directory..
/usr/local/tomcat/webapps/

please help me..thanks in advance for your help..
