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.
