Outdated: Upgrade JDK 1.3 to JDK 1.4 on Tomcat 4.1

This section provides a tutorial example on how to upgrade JDK 1.3.1 to JDK 1.4.1 for Tomcat 4.1.18 server on Windows systems.

Someone reported a JSP compilation issue while following my tutorials with Tomcat 4.1.29 and JDK 1.4.x. In order to understand the issue better, I upgraded my Tomcat 4.1.18 installation from JDK 1.3.1 to JDK 1.4.1 with these steps:

1. Checked my JDK 1.4.1 installation. The following command shows that I have JDK 1.4.1_01 working correctly:

>\local\j2sdk1.4.1\bin\java -version
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

2. Changed the "JAVA_HOME" environment variable and started Tomcat server with JDK 1.4.1 without any problem:

cd \local\jakarta-tomcat-4.1.18\bin
set JAVA_HOME=\local\j2sdk1.4.1

3. Created the following JSP page, hello.jsp, and copied to \local\jakarta-tomcat-4.1.18\webapps\ROOT:

<% out.println("Hello world!"); %>

4. Ran Internet Explorer (IE) with url: http://localhost:8080/hello.jsp. You should see "Hello world!" in the IE window.

I am pretty sure now my Tomcat server is running ok with JDK 1.4.1. See the next section for the Tomcat error with JDK 1.4 on a JSP page using my FirstBean.java.
