Eclipse IDE for J2EE 1.3 Development

Eclipse IDE for J2EE 1.3 Development
(Tomcat 4.x, JBoss 3.x, MySQL 3.x) by Hao Wu Last modified: 04/18/2002

Purpose
This article covers setting up the following Open Source tools for J2EE 1.3 development.

- Tomcat 4.x for Servlet 2.3 and JSP 1.2
- JBoss 3.x for EJB 2.0, JMS 1.1, JCA 1.0, and JAXP 1.1
- MySQL 3.x for RDBMS Persistence
- Eclipse for Java IDE

* These instructions assume Windows platform. Linux needs slightly different URLs & similar steps.
* Following the order herein is recommended.

Coming Soon...
This documentation will get diligent update, catching up with latest builds of the tools. So please come back for updates.

- ANT integration with Eclipse.
- Code examples.
- XDoclet integration into Eclipse for EJB development.

Installing JDK Version 1.4.0 Download

Get binary j2sdk-1_4_0-win.exe at http://java.sun.com/j2se/1.4/download.html
* Be sure to download the SDK, not just the JRE.

Documentation - Online - http://java.sun.com/j2se/1.4/docs/index.html
- Downloadable - http://java.sun.com/j2se/1.4/download.html Install

Run the executable which will install the following:

Java 2 SDK, SE v1.4.0 Java 2 Runtime Environment, SE v1.4.0 Java Plug-in 1.4.0 Java Web Start (1.0.1) Environment

Set variable JAVA_HOME to <install dir> (e.g. C:\jdk1.4).

Make sure <install dir>\bin is in your PATH (e.g. C:\jdk1.4\bin).

Test

Open a DOS windows, try java -version and you should get:

java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

Installing Tomcat Version 4.0.4 Beta 2 Download

Get zip binary at http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0.4-b2/bin/jakarta-tomcat-4.0.4-b2-01.zip
(General download at http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release .)
* Also available is an Install version, which can run as Windows service. Not recommeded for development.

Documentation - Online - http://jakarta.apache.org/tomcat/tomcat-4.0-doc/index.html
- Local - (after installation) at %TOMCAT_HOME%\webapps\tomcat-docs\index.html
(Also accessible at http://localhost:8080/tomcat-docs/index.html, if Tomcat is started on port 8080)   Upgrade from Previous Version

- Rename your previous installation (say C:\jakarta-tomcat-4.0.2 to C:\jakarta-tomcat-4.0.2_old). And remove it after you get the new version up for a while.
- After the installation, copy the old server.xml (or preferrably, just the context you added) to the new.
- After the installation, go over other Tomcat related sections and check for applicable changes.

Install

Unzip to destination (say C:\, which makes <install dir> to be C:\jakarta-tomcat-4.0.4-b2-01).

Environment

Set variable TOMCAT_HOME to <install dir> (e.g. C:\jakarta-tomcat-4.0.4-b2-01).

Test

"cd %TOMCAT_HOME%\bin" and "startup" (startup.bat), you should see ---

Starting service Tomcat-Standalone
Apache Tomcat/4.0.4-b2
Starting service Tomcat-Apache
Apache Tomcat/4.0.4-b2

Now that Tomcat is up, access http://localhost:8080 from your browser.

Other o Installing Sysdeo Eclipse Tomcat Launcher Plugin (refer to the later section)
o Integrating Tomcat with JBoss (refer to the later section)

Installing JBoss Version 3.0.0 Release Candidate 1 (soon will add a seperate section on building 3.1.0 Alpha by yourself) Download Get zip binary from SourceForge at http://prdownloads.sourceforge.net/jboss/jboss-3.0.0RC1.zip
(General download at http://sourceforge.net/project/showfiles.php?group_id=22866.)
* Also available is a Tomcat-integrated version at http://prdownloads.sourceforge.net/jboss/jboss-3.0.0RC1_tomcat-4.0.3.zip. We prefer having seperated Tomcat instead of the integrated version, especially for development, for the following reasons:
Debugging web application is harder - need to do build into .ear instead of using Tomcat server.xml to point to code. Encountered class loader problem from Tomcat to integrate with JBoss. Documentation - Free online manual (somewhat outdated): http://www.jboss.org/online-manual/HTML/index.html
- JBoss documentation site: http://www.jboss.org/doco.jsp. Upgrade from Previous Version

- Rename your previous installation (say C:\jboss-3.0.0beta2 to C:\jboss-3.0.0beta2_old). And remove it after you get the new version up for a while.
- After the installation, go over other JBoss related sections and check for applicable changes.

Install

Unzip to destination (say C:\, which makes <install dir> to be C:\jboss-3.0.0RC1).

Environment

Set variable JBOSS_DIST to <install dir> (e.g. C:\jboss-3.0.0RC1).

Test

Make sure you don't have TOMCAT running, as it would conflict with JBoss over port 8080. (Integration is covered in a later section.)

"cd %JBOSS_DIST%\bin" and "run" (run.bat), you should see console output and eventually ---

14:44:35,075 INFO [Server] JBoss (MX MicroKernel) [3.0.0RC1 Date:200204150356] Started in 0m:22s:383ms

Check console or logfile (%JBOSS_DIST%\server\default\log\server.log), you should only see "INFO", "WARN" or "DEBUG" outputs.
Try http://localhost:8080, you should see Tomcat document and example - this is served through the embedded Jetty JSP/Servlet container (not Tomcat).
Also, try http://localhost:8082, you should see the JMX management console.

Other o Disable clustering: If you might ever run JBoss on your machine without a network, you want to do this.
- Create a subfolder %JBOSS_DIST\server\default\deployBackup.
- Move file %JBOSS_DIST%\server\default\deploy\cluster-service.xml away into %JBOSS_DIST%\server\default\deployBackup.
