Now I seem to have a problem retrieving the data. It saves but now it won't retrieve.
It is kind of like in retrieving, it is going the other way, and since the parent
doesn't have info about the child in a reference descriptor tag, it is giving me an
error. Actually I am making an assumption here, which is also funny since the child
table is called Assumption.
Here is what I have. I have a Tour table, an Assumptions table, and a TourDates table.
A Tour one field, Band name. The assumptions table hold values for MPH, MPG, and cost
per gallon. TourDates stores 0 to many tour dates for the tour. So TourDates is also a
child table to The tour table, in a 0:many relationship. So some tours might not have
any dates yet associated with the tour.
Here is the exception stacktrace that JBoss shows
javax.servlet.ServletException: Servlet execution threw an exception at
