Transforming the e-Concordiensis

Motivation
There is little dispute that one of the primary goals of the press is to convey information. Traditionally,
this was done by printing it in the form of newspapers and magazines. Yet over time, technology, such
as the internet, has made it easier and quicker for people to get printed information from their favorite
sources. Today, most publications offer an electronic edition, but not all of these e-editions are created
equally. Some are rather complicated for their staff to create while others are painful to read. My senior
capstone design project addresses both of these potential problems through the creation of a custom
package designed for school newspapers, specifically the Union College Concordiensis.

Requests are made to the application by people surfing the site. These requests are passed
directly to the model portion of struts. The model then contacts the controller to decide the
appropriate action to take with the given request. For example, if the user is filling out a form
and misses a required field, the controller will redirect the user back to the page he or she has just
worked on to correct the mistake. At step 3, the controller may contact the database via a layer
of persistent objects as part of the package Hibernate. In doing this, the user does not need to
execute SQL commands, but rather can execute queries via a Hibernate Query Language. Rather
than returning fields, Hibernate returns lists of “value objects”. Finally, at step 4, the controller
passes data to the view which is then reassembled in step 5 using additional presentation layer
techniques, like merging additional jsp files for header and footer.
