Field Detail

INIT_PARAM_OVERRIDES

public static final String INIT_PARAM_OVERRIDES

The name of the ServletContext attribute under which we store any overrides for the init parameters of the ServletContext. Note that it is NOT possible to actual modify the init parameters specified in the web.xml file. Therefore, we attach the overrides as an attribute and then consult them from within contextInitialized(javax.servlet.ServletContextEvent) .
