The class edu.harvard.i2b2.crc.util.QueryProcessorUtil has a static block which which logs an error if it is unable to find the class oracle.jdbc.OracleDriver.

I believe this is confusing for non-Oracle database users who may be using the JBoss logs to work through installing i2b2. While it may be difficult to statically code for the variety of databases i2b2 patrons may use, the installer may think it much more likely he or she has an error in a configuration file rather than the server having a hard-coded Oracle dependency.
