I have a lot of data that needs to be available to all users, at any time (for example, the contents of drop-down menus, which I loaded from an XML file). From all the posts I've seen here, the recommended place to store global data seems to be the servletContext. Most people are setting up a ServletContextListener, and loading this data in the contextInitialized method.
But according to the servlet spec (http://jcp.org/aboutJava/communityprocess/final/jsr154/index.html), page 32:
"Context attributes are local to the JVM in which they were created. This prevents ServletContext attributes from being a shared memory store in a distributed container. When information needs to be shared between servlets running in a distributed environment, the information should be placed into a session (See ChapterSRV.7, „Sessions¾), stored in a database, or set in an Enterprise JavaBeans TM component."
I'm going to be running in a cluster...does this mean that I can't use the servletContext? If that's the case, I have two other questions: - When do I first put the data into the session? I don't think I have access to it in the ServletContextListener. - How do I prevent it from being replicated for all users?
Another question: I may have 50 or so pieces of data. When I store them (in either the session or the servlet context), would you recommend putting them all in as separate attributes, or wrapping them all into one bean and just storing that one bean as an attribute? Or does it not matter?
