Today I was trying to deploy a web application to Tomcat server. Publishing went smoothly with no errors. So I thought everything will work fine. But when I tried to access the application, page was not coming. On further study of the log files I could see a warning message in Tomcat console. The error message was

WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:AppName' did not find a matching property.

The solution to this problem is very simple. Double click on your tomcat server. It will open the server configuration. Under server options check ‘Publish module contents to separate XML files’ checkbox. Restart your server. This time your page will come without any issues.
