Hi All,

I keep getting this error after deploying JSP application to Apache server. The Apache server is running Sun 5.1 and im developing using MAC + Eclipse

I'm doing an export for the project after I'm done developing to ".war" file and place that file in the Tomcat 6.0 "webapp" folder

When i try to access it from the browser i get this HTTP Error:
HTTP Status 503 - This application is not currently available

So i tried deploying the examples that comes with the Tomcat, and that worked fine in the server and I can access it fine. However when I create a project and export it, same error happens.

The file structure of the provided example is different than what is produced by eclipse.

Your help please, what am I doing wrong? Sad

The log shows this error:
