Data in our j2ee project has not populated in several days

I can pay $2 for connecting to the code base and $2 extra for the resolution of this issue. The only caveat is that this issue gets resolved before moving on. At this point, I can also pay $1 for each additional resolution of any more issues that you find as long as you write down the expected resolutions for them prior to fixing them, either in a chat message or in our spreadsheet. I will almost always say yes immediately and let you tackle them.

Our page at https://staging.profitsharingprojects.com/carlist is no longer populating with new data and I need assistance in determining where the issue is so that I can hopefully take steps to resolve it with the help of someone far more experienced with Java than myself. This screencast provides a visual overview of the current status https://www.screencast.com/t/PvOllPC9w

Important pages:
src/main/webapp/public/carlist.jsp - This is the most important page on the site and the page most people are directed to
src/main/webapp/uc.jsp - The landing page
src/main/webapp/menu.jsp - The menu page.

CSS structure:
The older style sheet at src/main/webapp/res/moshcssjs/style.css will need to be eliminated over time and absorbed into the src/main/webapp/res/css/style.css as well as much of the in-line css so that src/main/webapp/res/css/style.css becomes the default location for most css. The pricing table is defined at src/main/webapp/res/css/pricing.css.
