Maximo 5, Maximo 6 or Maximo 7 has to be installed on the user's machine. Java 1.5 or higher and Eclipse 3.3 or higher are also required. If you have already set default java home on your machine (typically this is java used for running your application server), you can edit eclipse.ini file, and set the virtual machine used for running Eclipse in this file, like on the picture below. Another option is to create shortcut (for Windows system) and define this option in the target fields.
