Metacat

Create database and shared directories for database management code and shared code respectively.

Replacing MetaCatUtil.debugMessage or MetaCatUtil.logMetacat call with logMetacat (private Logger object) call

Added the EventLog functionality to the servlet as action=getlog. Valid parameters are ipAddress, principal, docid, event, start, end. All parameters can be repeated except start and end.

Partial implementation of a query facility for the access log. Need to fix problems with the date filtering, and tie this into the servlet action when completed and tested.

Interim checkin of EventLog reporting structure. Still basically incomplete but compiles.

Patched to make the date-time value insertion work under oracle. Now it
tests fine under both oracle and postgres. Still need to write an
access/query function.

Modified EventLog to eliminate the separate revision column and instead fold
that into the docid string. Log now includes read events, but need to update
the data sent there.

Modified SQL scripts to add the new access_log table. I've partially tested this under postgres but have not yet tested under oracle.

Added classes for basic event logging support. These classes write log entries to the database connection. Still to do: query the event log, write oracle sql code (postgres is done), possibly allow the log to be archived to a text file, and possibly do the dtabase writes asynchronously via a caching mechanism.
