To use the HTTP connection handler, you must first configure one or more servlet extensions. Servlet extensions are responsible for obtaining Java servlets (using the Java Servlet 3.0 specification as described in JSR 315) and registering them to be invoked using one or more context paths. If you plan to deploy the SCIM extension, then you should follow the instructions in Chapter 24, "Managing the SCIM Servlet Extension." For custom servlet extensions created using the Server SDK, the process varies based on whether you are using a Java-based or Groovy-scripted extension.
