DSpaceServlet
public class DSpaceServlet extends HttpServlet (Code)
Base class for DSpace servlets. This manages the initialisation of a context, if a context has not already been initialised by an authentication filter. It also grabs the original request URL for later use.
Unlike regular servlets, DSpace servlets should override the doDSGet and doDSPost methods, which provide a DSpace context to work with, and handle the common exceptions SQLException and AuthorizeException. doGet and doPost should be overridden only in special circumstances.
Note that if all goes well, the context object passed in to doDSGet and doDSPut must be completed after a JSP has been displayed, but before the method returns. If an error occurs (an exception is thrown, or the context is not completed) the context is aborted after doDSGet or doDSPut return.
