jIDEE :: Java IDE for Education
Requirements 
Operating System
jIDEE is curently supported on Windows 7 and Linux operating systems.1 A version for OS X will not be developed until a workable solution presents itself for Apple's deprecation of Java on that platform.
JDK
You must have both a recent Oracle Java SE Development Kit (JDK) installed as well as an Oracle Java SE Runtime Environment (JRE) to use jIDEE. Note that the JDK (Java Development Kit) and the JRE (Java Runtime Environment) are not the same thing. Typically, a JDK installation on Windows will also offer to install a JRE; so if you currently lack both, downloading the JDK package should suffice.
Installation 
Please carefully follow the instructions below for your operating system.
Windows 7
- If not already installed, download and install the Java SE Runtime Environment (JRE) and Java SE Development Kit (JDK).
- Install a supported text editor. Download and install either Programmer's Notepad or Notepad++. (Both are FOSS projects.) If one of these is already installed, you do not need to re-install it.
- Install jIDEE itself. Download the Windows installer and install.
Linux
- If not already installed, install the Java SE Runtime Environment (JRE) and Java SE Development Kit (JDK). Consult your distribution's documentation regarding whether these are available for your distribution. If not, you may have to perform a manual installation—in which case we feel very sorry for you.
- Install a supported text editor. Use your package manager to install any of the following (roughly in order of preference): geany, medit, gedit, kate, bluefish, or scite.
- Install jIDEE itself. Download the Linux binary bundle, unpack, and open the README for further instructions.2
Archives 
To download source code or older versions, visit the jIDEE releases repository. Rarely, you might find newer beta builds in the beta releases repository. Source code for the jIDEE project is held in Mercurial repositories.
Please let me know about any problems you might find so they can be addressed in upcoming releases.
1Limited testing indicates that jIDEE 2 works fine on Windows XP as well. However this OS is not officially supported. That means any support issues arising from Windows XP will not be addressed. If you are using Windows XP, you might consider using the most recent version that was written for that OS.
2If the Linux binary bundle doesn't work for you, please let me know. You may have to compile from source.
