Greetings-
You need to set the classpath variable in the Environment Variables section. %JAVA_HOME%\jdk1.6.0_xx\bin. JAVA_HOME is where you have installed the jdk.
I ran java with the Eclipse IDE. Two good resources: The Eclipse Foundation web site and the Microsoft (MSN) system (how to) pages. Also check the java.sun.com site. But that can be daunting. I'll try to log on tomorrow. But try the 2 sites.
You don't actually need Tomcat. YOu can set up an Apache-PHP-Java stack, but you'll have to use Eclipse v.3.2 with the jdk 1.5.x
A bit tricky, but if you can get an installer script _ look at the Eclipse web site - for an installer ( .msi file), it will be easier.
Regards
