== 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. Oracle-XE is limited to 4GB of space and 1GB of memory.

Question: Is there a limitation on the number of users?

My best guess at the moment is that we will not exceed 500GB of database space within the first year. We should have enough latitude to investigate whether !MySql or Postgres might be used before we run out of steam with Oracle-XE.
