Field Genetics is the company that distributes Cervus, the
popular Windows program for error-tolerant likelihood based
parentage analysis. In 2006 they approached Conissaunce and
asked us to help them produce a new web site as part of a major
update to the Cervus product (version 3.0).
The Field Genetics project presented some quite unusual challenges.
The primary audience are academics, so the site needed to
avoid being too flashy or commercial looking, but at the same
time the company was looking to expand its audience into the
commercial sector so we needed to make sure the site looked
sufficiently professional for that audience. Maintenance of
the site is done by Field Genetics themselves so we needed
to ensure that the design of the site made this straightforward.
Design and Technology
The site uses the standard JEE web technology stack (JSP,
Servlets, JSTL, JDBC) and makes use of the Apache Commons
Collection. Rendered pages are XHTML compliant. The solution
is deployed to a Linux server with Apache and Tomcat providing
the web server and MySQL the database.
Each page is built off 3 .jsp fragments - a unique controller
page with a common header and footer. A template is provided
to allow new pages to be created and added to the site.
For the login and customer registration portions of the site a
variation on the conventional MVC pattern was implemented.
The JSP page acts as both view and controller, calling a servlet
to populate/update the model. Helper methods are then exposed
to the page via tags to allow population of dynamic elements.
The servlet uses a connection broker to manage database connections,
and interacts with a pair of Data Access Objects that use
JDBC to read and write to the database.
The site design, templates, servlets and documentation were
done in 5 days and handed over to Field Genetics to add their
the web site
