Get Projectivity Binaries
From Projectivity Sourceforge Project download area you can download the Projectivity binaries.
This is an archive that bundles Projectivity and JBoss Application Server 4.2.3GA
This is the preferred way to run Projectivity since not only it was compiled and tested by our team of experts but also it comes with the Application Server (ie the system that runs Projectivity) fully configured and certified.
You need to build from the sources only if you plan to customize Projectivity.
