• to talk to hibernate using the following configuration file:

  <?xml version="1.0" encoding="UTF-8"?>

• Well, connecting to the db with jdbc instead of running through Hibernate got things up to speed quite quickly. I am running arbitrary queries against the databases (including information_schema, which Hibernate chokes on). The results are wrapped in objects that rules can be run against.
•  Handle what happens when a null is returned by WrappedMap.getObjectByName().
• Determine primitive type and handle accordingly
• Looks like my ability to charge the CSIP contract ran out on the 9th. Need to figure out what to do with the 12 hours I charged since then. Jim is working on it. Ok. Charge half of today and all of yesterday and stop.

12:30 – 4:30 FP

• Worked on paper, then lost the ability to scroll past page one. Going to try this at home…

7:00 – 9:30 FP

• Finished incorporating paper changes and sent back to Dr. Kuber.
