Time sheet data pull not updating when refreshed.

I have a Plain Java API web based application that displays time sheet information from RTC to the user for the work items they have open or that have closed within the last 7 days.  When the application first comes up, the timesheet information is pulled from the RTC Repository just fine with the code below.  If the user then goes into RTC and updates one of the timesheet elements (lets say to add some hours, and yes they save the hours), and then refreshes the web application, the new hours added do not show up on the display.

In testing, I have gone so far as to close the browser and come back in, and refreshed in every way I can think of, but the data still shows the original pull.  If I stop and restart the web server, then the data is refreshed.  Does anyone know how I can direct the data to refresh?  I have traced the code, and every time the getReferences() method is called, it returns only the first timesheet entry, not the newly added one.

Thanks,

Bill
