Tomcat works but my webapps not reachable!

[josepco]

Hi,
I installed jakarta.Tomcat/5.0.28. It works well. The examples work also.
I put my wep application in /usr/local/tomcat/webapps/myApp,
and when I try

http://localhost:8080/myApp/index.htm

I have this message:

HTTP Status 404 - /myApp
type Status report
message /myApp
description The requested resource (/myApp) is not available.

So I can't understand why I can access to the tomcat's examples but not my web application.

Any idea?
Thanks for helping.
