Tomcat has different WAR deployment ways. Some work, some don't. Please try the following deployment methods :

• Manager Application: Locate the WAR file

This means something is wrong with your application configuration or startup.

There is always information about that in the logs - check logs/catalina.out and figure out what is wrong.
