I found how to change ports.<br />
In web.properties.<br />
but unfortunately after some modifications(8000 -&gt; 80)<br />
the browser complains.<br />
The message is as follows.<br />
<br />
=====================<br />
J2EE SDK/1.3.1 - HTTP Status 500 - No Context configured to process this request<br />

I downloaded J2SDK1.4 and J2EE sdk 1.3.1 and installed them.<br />
Lucky enough, I was able to run and see the default web page named index.html and get the congrats message.<br />

What next?<br />
<br />
I have to run servlets and jsp files. <br />
<br />
I'm not quite sure how to configure environments.<br />

1. How can I conigure environments, mapping virtual folders to actual folders, changing port numbers?<br />

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
