title: How do I dynamically update the reference data in J2EE application
body: <p>My application is hosted on weblogic 10.3. We are using Jee 6. 
  In our application we have lot of reference data which needs to be updated once in a while without restarting the server. This reference data is used in other part of the application as drop down option and those dropdown option should show the latest update. Most of the reference data table structure is very similar.
  I would like to know what is the best way to achive the requirements with least amount of code. 
  If Jee has any built in feature for this kind requirements(I belive this is std requirement in most of the web applications)</p>
