restInitApplication("full absolute path",..) w/in Application.cfc's pseudo-constructor throws null pointer

Repro:

C:\inetpub\wwwroot\Application.cfc
----------------------------------
component {
  THIS.name = "TestRest";
  THIS.restSettings.skipCFCWithError = true;
  restInitApplication("C:\inetpub\wwwroot", "RestTest");
  //function onRequestStart() {restInitApplication("C:\inetpub\wwwroot", "RestTest"); return true;}
}

1) Create C:\inetpub\wwwroot\Application.cfc as per above
2) Browse to http://localhost and see exception (attached) and REST app is not registered in CF Admin
3) Comment out this line: restInitApplication("C:\inetpub\wwwroot", "RestTest");
4) Uncomment this line: function onRequestStart() {restInitApplication("C:\inetpub\wwwroot", "RestTest"); return true;}}
5) Browse to http://localhost and then see REST app is registered in CF Admin

RestInitApplication("full absolute path",..) should also work in the pseudo-constructor, or a better exception should be thrown. (ex: "RestInitApplication() is not allowed within Application.cfc's initialization code."). I only found this issue b/c I was testing REST. Most users will not run RestInitApplication() in Application.cfc's pseudo-constructor. Thus, I am fine w/ the current behavior - but the exception message should be helpful (not null pointer).

Comments:

It's _annoying_ that when the bugbase session times out, it discards any pending notes we've typed. I'll try to remember what I wrote.. On second thought, I'd keep current behavior but change the error message. Reason: b/c even RestInitApplication("/mymapping") (where "/mymapping" is defined in CF Admin AND in Application.cfc's pseudo-constructor) would cause confusion when ran within Application.cfc's pseudo-constructor if "/mymapping" was pre-defined to a different path via CF Admin. B/c within Application.cfc's pseudo-constructor, RestInitApplication("/mymapping") would still be using the path defined in CF Admin. So, yeah, just change the error message to be more helpful please. Ex: "RestInitApplication() is not allowed within Application.cfc's initialization code." The current Null Pointer message isn't helpful at all. Thanks!, -Aaron

Hmm, using restInitApplication() w/in onRequestStart() is problematic as well (code is above, in description). Even if no CFCs have been modified (including Application.cfc), calls to REST-enabled CFCs throw this exception: "Error","ajp-bio-8012-exec-3","10/15/12","02:04:49","TestRest","object is not an instance of declaring class The specific sequence of files included or processed is: C:\inetpub\wwwroot\Restservice.cfc'' " java.lang.IllegalArgumentException: object is not an instance of declaring class See? "TestRest" is the application's name (THIS.name="TestRest"). Thus, that exception is regarding Application.cfc itself. Shouldn't RestInitApplication() ignore Application.cfc files?

And, btw, the error that's logged to coldfusion-error.log is: SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container java.lang.IllegalArgumentException: object is not an instance of declaring class The error message in my previous post was from exception.log. Basically, user does not see a CF exception. User sees a web server exception. So these REST exceptions should probably be handled better.

I have checked this scenerio in CF10 update 11 and it seems to work fine: Following first 2 steps: No exception is thrown and the REST app is registered in CF Admin Can you please confirm (Comment added from ex-user id:nawani)

Hi Anuj, Splendor Public Beta still throws Null Pointer exception. Steps to Reproduce: 1) Create C:\inetpub\wwwroot\Application.cfc having this: component { THIS.name = "TestRest"; THIS.restSettings.skipCFCWithError = true; restInitApplication("C:\inetpub\wwwroot", "RestTest"); } 2) Browse to: http://localhost 3) See Null Pointer exception is thrown and REST app is not registered in CF Admin Thanks!, -Aaron

Hi Anuj, This issue still exists in CF 11 Update 3 (11,0,03,292245(PreRelease)) on x64 Windows 8.1 Pro, using the repro code in my last comment (on 10:23:50 PM GMT+00:00 Feb 27, 2014). Using restInitApplication(expandPath("./"), "foo") in Application.cfc's pseudo constructor throws java.lang.NullPointerException. Thanks!, -Aaron

If the Application.cfc conatins RESTInitApplication of the same appilcation in its pseudo constructor, the initialization was going to infinite loop causing the Application not fully initialized. So it is throwing NullPointerException on registration. Fixed the issue such that, if the same application is tried to initialize again, we are throwing exception.

Hi Adobe, I've verified this is fixed in CF2016 Update 1 (build 2016.0.01.298513), as restInitApplication(expandPath("./"), "RestTest") in the Application.cfc pseudo constructor throws: "In Application.cfc pseudo constructor, the same Application cannot be registered as REST service." I just now realized Application.cfc -itself- can be used as a REST-enabled CFC. Interesting. Now I understand what you were saying Paul :) Thanks!, -Aaron
