Installing the Java Software Development Kit
Tomcat 5 is a pure Java web server with support for the Servlet 2.4 and JSP 2.0 specifications. In order to use it, you must first install a Java runtime environment. If you don’t already have one, you can download a Java runtime for Windows, Linux, and Solaris at http://java.sun.com/j2se/.
I recommend that you download and install the Java 2 SDK (a.k.a. JDK), as opposed to the slimmed-down Runtime Environment (JRE) distribution. The reason is that JSP requires a Java compiler, included in the SDK but not in the JRE.
Another alternative is to use the JRE plus the Jikes compiler from IBM (http://www10.software.ibm.com/developerworks/opensource/jikes/). Tomcat can be configured to use Jikes instead of the javac compiler available in the Java 2 SDK from Sun; read the Tomcat documentation if you would like to try this. To make things simple, though, I suggest installing the Java 2 SDK from Sun. The examples were developed and tested with Java 2 SDK, Standard Edition, v1.4.2. I suggest that you use the latest version of the SDK available for your platform.
If you need an SDK for a platform other than Windows, Linux, or Solaris, there’s a partial list of ports made by other companies at: http://java.sun.com/cgi-bin/java-ports.cgi.
Also check your operating-system vendor’s web site. Most operating-system vendors have their own SDK implementation available for free.
Installation of the SDK varies per platform but is typically easy to do. Just follow ...
