Example 1 with SlingServletConfig

use of org.apache.sling.servlets.resolver.internal.helper.SlingServletConfig in project sling by apache.

the class SlingServletResolver method getDefaultServlet.

     * Returns the internal default servlet which is called in case no other
     * servlet applies for handling a request. This servlet should really only
     * be used if the default servlets have not been registered (yet).

Example 2 with SlingServletConfig

use of org.apache.sling.servlets.resolver.internal.helper.SlingServletConfig in project sling by apache.

the class SlingServletResolver method getDefaultErrorServlet.

     * exception.

     * "sling/servlet/errorhandler" and method "default". This may be
     * overwritten by applications globally or according to the resource type
     * hierarchy of the resource.
     * <p>
     * If no default error handler servlet can be found an adhoc error handler
     * is used as a final fallback.
