Any Java platform of JDK 1.4 5 or later.
We regularly test ServiceMix on Windows, OS X, Solaris and Linux. I'm sure we could certify ServiceMix works on other platforms if required. If you have a platform that is not listed and would like us to certify it then contact our support teamServiceMix is regularly built and tested on Linux, Windows, Mac OSX, Solaris, and HP-UX. The core ServiceMix code will build and test on AIX and IBM i (aka i5/OS, OS/400) but certain components have problems due to the IBM JDK implementation.
