RE: Java under Fedora

[Patrick Kobly]

FWIW, If you're looking to do anything moderately serious, you're going to want to
use Maven to manage your build and dependencies...

$ mvn archetype:generate -DgroupId=com.foo.app -DartifactId=helloworld
-DarchetypeArtifactId=maven-archetype-webapp
$ cd helloworld

add 
<dependency>
  <groupId>org.apache.tomcat</groupId>
  <artifactId>tomcat-servlet-api</artifactId>
  <version>7.0.12</version>
</dependency>

to the <dependencies> element

$ mkdir src/main/java

Add source files into src/main/java, jsp's / static resources into src/main/webapp,
Your web.xml is in src/main/webapp/WEB-INF

To build a .war file:
$ mvn package

The war file will be sitting in target/helloworld.war
