RecordTimeServlet.java

The RecordTimeServlet uses the RecordTimeWorkflow to retrieve and update time-cards If no entry or new charge code is specified, the RecordTimeServlet retrieves the current timecard and builds an entry form If an entry is submitted, the RecordTime-Servlet first updates the timecard through the RecordTimeWorkflow and then builds

an entry form If a new charge code is specified, then the RecordTimeServlet creates new zero hour entries for the charge code, updates the timecard, and then builds an entry form.
