JAIDA is intended for use in simple standalone Java applications. It provides the full AIDA functionality for Java, but only limited "GUI" functionality. JAS3 builds on the functionality of JAIDA and adds many GUI based interactive analysis tools. JAS3 is available from http://jas.freehep.org/jas3 .

In JAS3 it is possible to execute any AIDA program written in either Java, Jython or Pnuts.
