How to start this damn servlet on the damn Tomcat!

How-to: Eclipse and Tomcat
In this tutorial you will learn how to setup a Sun JSF RI 1.2 (Mojarra) playground with Eclipse 3.3 (Europa/Ganymede) and Apache Tomcat 6.0 (Catalina). A JSF 1.2 environment requires at least the Java 5.0, JSP 2.1 and Servlet 2.5 API’s. We’ll download and install Java SE 6 SDK, Eclipse 3.3 IDE (with WTP for Java EE development) and Tomcat 6.0 Application server (which supports JSP 2.1 and Servlet 2.5 API’s). Additionally we’ll also download and install JSTL 1.2 which can be used in combination with JSF, thanks to unified EL.
