Hi, I tend to go for option 2 or to use JNDI, which may help when using a Servlet container. Unless your ServerResources are extremely generic, it's quite likely that they're going to have to know what to expect to load from the context (or JNDI). One way to make sure changing the attribute names is consistent would be to use constant names (and also prefix them with your domain name, to avoid clashes, like Java package names).
In addition, if you really want to pass information from the Component Context to the Application Context, you could set the Component Context to be a class that extends the default Context and overrides createChildContext() to let some attributes through. Option 4 (getters and setters) in Application can work well too, since you can get the Application from the ServerResource. You'd have to do a type check/cast. Best wishes, Bruno.
