Does REST work?

[Adam Cameron]

G'day:

I'm troubleshooting some code for someone on Twitter (https://twitter.com/cyndi104/status/600783012775747584).

Running the code on ColdFusion, I get the issue as per what Cyndi was seeing.

I wanted to see how Lucee handled the same (in an attempt to plug Lucee to her), but I can't seem to get REST to work on Lucee (4.5 or 5).

Here's what I did:

* The three files in her gist are in this dir: D:\Websites\www.scribble.local\shared\junk\cyndi

* In Lucee server admin, I set up a REST mapping - /cyndi - pointing to that dir. I opt for it to NOT be the default app

* I also check the option to list REST services if I browse to /rest

* I have modified her code so that the URLs are http://#CGI.http_host#/rest/cyndi/, not http://www.yoursite.com/

These are the steps I took on CF, and they work.

On Lucee, when I browse to /rest, I get this:

Available sevice mappings are:

• /rest/cyndi

So far, so good. If I browse to /rest/cyndi, I get:

no rest service for [/cyndi] found

Perhaps fair enough, as the end points have specific names in that code, and I'm not actually browsing to them

However if I browse to one of the defined endpoints, eg: /rest/cyndi/MyHandler1/MyTest/true, then I get this:

Lucee 4.5.0.042 Error (missinginclude)
Message	Page ../../../../../../null [C:\null] not found
Java Stacktrace	Page ../../../../../../null [C:\null] not found    at lucee.runtime.PageSourceImpl.loadPage(Unknown Source):-1    at lucee.runtime.component.ComponentLoader.loadComponent(Unknown Source):-1    at lucee.runtime.component.ComponentLoader.loadComponent(Unknown Source):-1    at lucee.runtime.rest.Mapping._init(Unknown Source):-1

etc.

Same on Lucee 5.

It looks very much to me like a bug in Lucee, but given what a drama ColdFusion has managed to maker out of /rest services, it would not surprise me if Lucee had non-obvious "idiosyncrasies" too.

Is there something else I need to do?

Cheers.

does this one work?

     /rest/cyndi/MyHandler1/MyTest/true

try putting / before restpath

looks like it is the data type on the arguments

data on the URL (and POST) scope are stings

try this

component rest="true" name="myHandler2" restPath="MyHandler2" output="false" {

remote any function GetHandler(required string booleanVal restargsource="path") 

restpath="MyTest/{booleanVal}"  

httpmethod="GET" produces="application/json" {

return arguments.booleanVal;  //booleanVal will be no because yes was passed in not true

}

}

It's not even finding the file mate; it doesn't matter what's in it!

Hmmm... some more information here. For the sake of completeness I decided to demonstrate AJ's suggestion isn't relevant, but am at home now so needed to set the code / mapping up again on my home machine (I was @ work y/day). And on this machine it works fine on Lucee 5. 

On Lucee 4.5 I get this:

So that's interesting.

On Railo 4.2.2.004 final it works fine too.

I have another machine here... I'll try on that too and report back.

Is there any sensible troubleshooting steps I can take with this on the machine that's erroring, or more info that's worth providing?

Can someone else try running that code on their rig and see what they get?

Cheers.

Same result on the other machine: Lucee 5 A-OK; Lucee 4.5: StringIndexoutOfBoundsException

One thing that occurs to me about my work machine... I might have done the mapping wrong. My Lucee installs are on my C: drive, and the websites are on the D: drive. I've a symlink in my Lucee  webroot pointing /shared to D:\websites\shared (so C:\apps\lucee\5\express\webapps\ROOT\shared is actually a resource on D: drive). Now I think I perhaps added the REST mapping via the D: drive directory, not the C: drive one. That might explain why Lucee is getting confused. Can't check this now, but will check on Mon.

AND... whilst my home machines are all C:-based, I still symlink in the shared dir into the Lucee webroot from another location. And indeed I was giving it the "wrong" path in the REST mapping: I was using the "real" path to the directory, not the linked one. Once I used the linked one on Lucee 4.5, it worked fine.

Odd how Railo 4.2 and Lucee 5 still manages to work it all out just fine. But not an issue, just "interesting".

So... nothing to see here... move along...

The same problem, why did it not resolved so far?

Also frequently down, and less trust in the lucce.

I will came back to railo.

Where your chances of having issues resolved right now are "../../../../../../null [C:\null] not found".

[김태식]

I installed to my windows server. (tomcat 8 and lucee war)

Then I will setup the rest mapping in lucee web admin, And the other is not a problem.

But rest, nothing happened. Tomcat does not recognize and display the 404 error.

Check your web.xml  in the expanded war. The rest servlet might be commented out.

It was a waste of time in three days., It's too tired.

Railo also problem in tomcat 8 (8.0.24 version).

. whole configuration file no problem in conf/web.xml, WEB-INF/web.xml (both same)

(Issues)

- rest : not working 

- flex2gateway :not working.

  (error message :  MessageBrokerServlet failed to initialize due to runtime exception: Exception: flex.messaging.config.ConfigurationException: Please specify a valid 'services.configuration.file' in web.xml ...)

. URL : rest.juloomob.net

  - rest.juloomob.net/rest/

  - rest.juloomob.net/flex2gateway

This files are web.xml file (web-inf/web.xml, conf/web.xml)

I removed lucee.war and installed railo.war to ROOT.from tomcat 8.0.24

but happened the same results.

Thanks.

I founded the reason, rest directory created in webapps directory, so mapping is missing.

Maybe, I followed the documentation in other website, they will guide to wrong.

Be collapsed. 

So, finally rest supported, flex2gateway problem.

Thanks.
