Normally, you would put such conditional activation code in a ServletContextListener, and have it throw an exception if things are not to your liking. Doing so would prevent any further use of the webapp. If you must do this on a servlet by servlet basis, then any servlet detecting a problem could set a flag in the ServletContext, which could be checked by a filter to see whether or not to allow requests through. > the ServletContext is in web app scope but it *is* > not a webapp (or is it?). There is a one-to-one correspondence between a ServletContext and a webapp; see SRV9.2: "The servlet container must enforce a one to one correspondence between a Web application and a ServletContext. A ServletContext object provides a servlet with its view of the application." - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
