  A multi-platform validation and analysis framework for public Monte Carlo
simulation for high-energy particle collisions is discussed. The front-end of
this framework uses the Python programming language, while the back-end is
written in Java, which provides a multi-platform environment that can be run
from a web browser and can easily be deployed at the grid sites. The analysis
package includes all major software tools used in high-energy physics, such as
Lorentz vectors, jet algorithms, histogram packages, graphic canvases, and
tools for providing data access. This multi-platform software suite, designed
to minimize OS-specific maintenance and deployment time, is used for online
validation of Monte Carlo event samples through a web interface.
