How to debug openfire with eclipse

Openfire is a well-known open-source Jabber server developed by Java. It was previously called Wildfire and was later changed to openfire. I previously looked at how it was debugged online.ArticleThis article is based on openfire.Community(Http://www.igniterealtime.org/forum/index.jspa? Categoryid = 1. there is a lot of content on it.

Openfire SVN + eclipse 3.3 + subversive Installation Guide
Posted: Jul 5, 2007 pm
If you're looking for an SVN (subversion) source of openfire + eclipse 3.3 Installation Guide, you're looking at the correct place. Otherwise, please see http://wiki.igniterealtime.org/display/WILDFIRE/Build+Openfire+with+Eclipse

This Guide assumes that you are installing everything from scratch. if you 've done some parts of them, this Guide may be still be useful, but your mileage may vary. I compile this guide to the best of my knowledge. I apologize if it doesn' t work for you.

Note: This Guide may also work with other jive's opensource projects like spark, etc. All you have to do is to change the svn checkout point to the desired project.

Openfire SVN + eclipse 3.3 + subversive Installation Guide

Install JDK
-Download JDK and install them. The least version shocould be 1.5. I use 1.6. Sorry, no instruction for this.

Install eclipse 3.3

-Extract the donwloaded ZIP file into "C:/program files/Eclipse"
-Open "C:/program files/Eclipse" folder
-Rightclick & drag eclipse.exe on to your desktop (or Windows taskbar) to create a shortcut cut icon
-Right-click the shortcut cut icon and choose "properties". The "Eclipse properties" window will show.
-The "target" textbox shocould read something like this "C: \ Program Files \ eclipse \ eclipse.exe"-VM "C: \ Program Files \ Java \ jdk1.6.0 \ bin \ javaw "depending on the JDK that you use.
