== i2b2 Software Prerequisites ==

=== JDK ===
The recommended version is 6.0 or higher. A JDK is required as the deploy procedures involve compilation.

=== JBoss ===
The recommended version is 4.2.2GA. I've gone with this so far, but would like to experiment with a later version.

=== Apache Ant ===
The recommended version is 1.6.5 but I've used 1.7.1 and I suspect any at 1.6.5 or above would be suitable.
Ant is required for deployment.

=== Apache Axis2 ===
The required version is 1.1

=== Oracle ===
The recommended DB flavours are Oracle and SqlServer.
The install goes with the free Oracle-XE 10.2.0.1, which is 32bit on the Linux environment.

My best guess at the moment is that we will not exceed 500GB of database space within the first year.
Oracle-XE is limited to 4GB of space and 1GB of memory.
Question: Is there a limitation on the number of users?

We should have enough latitude to investigate whether MySql or Postgres might be used before we run out of steam with Oracle-XE
