reload collections that initialized on startup?

[Dave Bosky]

I have a servlet that loads several collections that are using to populate dropdown listbox. Snippet below.

  
public void init() throws ServletException  {
 Collection projectLevelList = bus.getProjectLevelList();
 getServletContext().setAttribute ("cbProjectLevelList", projectLevelList);
}

This servlet is configured to load on startup in my web.xml file.
How can I reload this list after I add new values to the list?

Is there a better way to accomplish caching of collections used to populate common listboxes?

Thanks....
Dave

Yes.
Use a context listener to load the values into either a singlton object or a context scoped bean. Then, have your servlet read from that object at run time.
