Must install separately:
- Java: version 1.5 or later
- Jython: version 2.2a1x is included with the SPARK release, which is a patched version of the 2.2a1 release of Jython -- this is not an official build of Jython and cannot be downloaded from the Jython Web site. If you are developing out of the SPARK CVS repository, you can install this version by unzipping spark/lib/jython22a1x.zip.
NOTE: it is possible to run SPARK in a pure Python mode, though some of the builtin functionality, such as the OAA integration, will not work. For details on this, please contact spark-support.
