What is difference between WAR and JAR?

Should I use Tomcat for static content?
The most common reason why you would want this functionality is if you plan to use Apache to serve static content in front of Tomcat.

How do I configure Tomcat?

How do I change the default context settings for Tomcat?
Default context settings applied to all deployed contexts of your Tomcat installation can be adjusted in the context.xml file. The catalina.policy file, which replaces the java.policy file packaged with your chosen JDK, contains permissions settings for Tomcat’s elements.
Why can’t I reload Tomcat context without restarting it?
This is because it makes modifying the Context configuration more invasive since the main conf/server.xml file cannot be reloaded without restarting Tomcat. Default Context elements (see below) will also overwrite the configuration of any elements placed directly in server.xml.
