Sharing servletcontext with an object

Question

Hi
If I create an object through a servlet or JSP, an object that is not a servlet itself, how can I get a copy of the ServletContext to that object (so it can use other objects in the ServletContext) other than passing in the ServletContext in a constructor or method or something?
Thanks,
Dan

If you're asking whether there is a method to call from the object that will return a reference to the ServletContext, then there isn't one.
If the object contains business logic, then it should be independent of how the request came in. i.e. business objects should not be aware that they are running as part of a JSP/Servlet app. If other object references are needed, they should all be passed as arguments to the constructor or method. You could also create a "global" object that includes references to several other objects and pass the global object ref via an argument.
If your object is a JSP or servlet helper object that is designed to be aware of the environment, then it's ok to pass the ServletContext reference to a constructor or method.
