Hi,

I would like to know what packages are out there that can be used to create installers to distribute applications.

The target application is written in Java. The installer must be able to:

• be compiled via an ant script
• be compiled Linux (and Windows)
• run on Windows and Linux
• detect / handle previously installed versions of the application

We currently use IzPack, because it does all of the above, except the latter: It cannot easily detect previously installed version of the software.

Are there any other packages out there which fit the bill?

Thank you!
