Answer 1

Try to implement a javax.servlet.ServletContextListener and inside implementation of      
public void contextInitialized(ServletContextEvent sce) method write your Code to Pull up master data from respective Datasource bind it to a Java Object Something like a JavaBean or some random Collection class would be appropriate & finally save it under the scope of ServletContext or use a Static type to cache the Master data Object in the memory.
Adn configure the Listner in your web.xml accordingly.
Or
Write your code inside init(ServletConfig config) method of a servlet and make sure you configure the servlet in such a way that it executes init(ServletConfig config) method at the time of intialization (in web.xml under servlet configuration you use <load-on-startup/>)
and the rest if same as that of what i mentioned for ServletContext listener.
Hope that might answer your question.
