ConverterUtils.jsonToMap() not able to handle 'simple' JSON Object

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Send 'simple', one-dimensional JSON object via RestBuilder class (taken from 
Grails REST Client Builder Plugin 
[http://grails.org/plugin/rest-client-builder]). For example:

<code>
// create JSONObject
def jObj = new JSONObject()
jObj.put('id', 'theId')
jObj.put('name', 'yourNameHere')

// try to send it as parameter
</code>

2. Retrieve the following ERROR message:

3.

What is the expected output?
----------------------------
I expect the method to take the parameter(s) and process them correctly, as it 
will send a JSON Response and - sarcastically - the response IS a 
one-dimensional Array...

What do you see instead?
------------------------
ERROR container.ContainerResponse  - The RuntimeException could not be mapped 
to a response, re-throwing to the HTTP container
Message: Cannot cast object 'jsonRequestId' with class 'java.lang.String' to 
class 'java.util.Map'

... which leads to ConverterUtils.jsonToMap()

What version of the product are you using? 
------------------------------------------
Plugin Version:    0.6
Grails Version:    2.2.0

On what operating system?
-------------------------
Windows 7 64bit

Please provide any additional information below.
------------------------------------------------
It seems that it happens within the ConverterUtils.jsonToMap() function, 
precisely at line 100:
<code>
params.iterator().next().value
</code>

'params' is a valid GrailsParameterMap object which contains my two values 'id' 
and 'name' - as I've seen through debugging ...

----
However, it DOES WORK if I provide an at least two-dimensional structure. For 
example:

<code>
// create JSONObject
def jObj = new JSONObject()
jObj.put('id', 'theId')
jObj.put('name', 'yourNameHere')

// create a container JSONObject
def jContainer = new JSONObject()
jContainer.put('param', jObj)

//try to send it as parameter
</code>

this will result in a proper processing and I will retrieve the expected 
response message from the server ;)

I've committed a fix at rev. cb818df843893bc6fd0ebbd9000ae120164902a9.
Care to try it out?

thanks a lot - I'll definitely try it out! sadly, I can do this tomorrow at the 
earliest - but I'll try it out and return with my experiences as soon as 
possible! promised :)

hey,
I tried it out but I ran into several errors on startup. so, just to clarify my 
situation I will write down the steps I've tried so far:

1st approach:
-------------
# clone git repository
# open source with Intellij and create a valid Intellij project
# clean and compile the plugin ('grails clean' followed by 'grails compile')
# package the plugin ('grails package-plugin'), creates a grails-jaxrs-0.7.zip 
file
# create a new Intellij Grails project (with latest Grails version: 2.2.0)
# install plugin from file via ('grails install-plugin c:\path\to\file.zip')
# create a new resource ('grails create-resource my.package.MyResource')
# try to compile the new project with 'grails compile'

2nd approach: 
-------------
# create a new Intellij Grails project (with latest Grails version: 2.2.0)
# declare plugin in 'BuildConfig.groovy' file 
<code>
grails.project.dependency.resolution = {
  plugins {
    compile ':jaxrs:0.7'
  }
}
</code>
# clean the project with 'grails clean'
# compile the project with 'grails compile'

with both approaches I ran into an compilation error (more precisely 93 
errors). I attached the console output as a file below...

Have you tried running the 'refresh-dependencies' goal?

Original comment by n...@10ne.org on 19 Feb 2013 at 12:31

[GoogleCodeExporter]

yes, I did. forgot to mention it earlier but it gives me the same errors as in 
the log I attached to the previous message. tried it again just this very 
moment and it's the same result.

Curious, I can't reproduce it; I'll have to give it another go a little later

Really strange... hmmm... here's my BuildConfig.groovy file if it's any help 
for you...

Does it make any difference if you install the plugin via code?
That is, instead of re-packing and installing, add the reference of the 
checkout directory to the build config file :

grails.plugin.location.'jaxrs' = '../grails-jaxrs'

sorry for not responding for a while, but I was very busy doing other work here 
at office as well. I tried it as you suggested and added a reference to my 
BuildConfig.groovy file for the jaxrs plugin but it didn't make any difference 
(I tried this on a clean project).

so, I moved on and just wrapped all my JSON objects I send to the RESTful Web 
API within a JSON container object. this runs fine if I run the app via 'grails 
run-app'. however, if I run the app via 'grails run-war', or if I deploy the 
generated WAR I see the a lot of errors, resulting in these lines as last 
listed cause:
<code>
Caused by: java.lang.NoClassDefFoundError: 
org/grails/jaxrs/support/RequestStreamAdapter
    at org.grails.jaxrs.support.ConverterUtils.jsonToMap(ConverterUtils.groovy:94) ~[ConverterUtils.class:na]
</code>

am I missing something? I guess it's not a matter of missing libraries as it is 
running like a charm when started via 'grails run-app' ...

I'll try to reproduce it again, but it seems fine.
Perhaps someone else can chime in and try it out.

Hi,

I am also facing this problem. I've passed all the steps described above, and 
the only compilation error that I'm getting is:

jaxrs-0.7\src\groovy\org\grails\jaxrs\itest\IntegrationTestSpec.groovy: 5: 
unable to resolve class spock.lang.Shared
 @ line 5, column 1.
   import spock.lang.Shared
   ^

jaxrs-0.7\src\groovy\org\grails\jaxrs\itest\IntegrationTestSpec.groovy: 3: 
unable to resolve class grails.plugin.spock.IntegrationSpec
 @ line 3, column 1.
   import grails.plugin.spock.IntegrationSpec
   ^

jaxrs-0.7\src\groovy\org\grails\jaxrs\itest\IntegrationTestSpec.groovy: 12: 
unable to resolve class grails.plugin.spock.IntegrationSpec 
 @ line 12, column 1.
   abstract class IntegrationTestSpec extends IntegrationSpec implements JaxRsIntegrationTest {
   ^

jaxrs-0.7\src\groovy\org\grails\jaxrs\itest\IntegrationTestSpec.groovy: 16: 
unable to resolve class spock.lang.Shared ,  unable to find class for annotation
 @ line 16, column 5.
       @Shared
       ^

jaxrs-0.7\src\groovy\org\grails\jaxrs\itest\IntegrationTestSpec.groovy: 19: 
unable to resolve class spock.lang.Shared ,  unable to find class for annotation
 @ line 19, column 5.
       @Shared
       ^

In spock-0.7 grails plugin page it is said, that if using Grails 2.2, then the 
following lines should be added:

grails.project.dependency.resolution = {
  repositories {
    grailsCentral()
    mavenCentral()
  }
  dependencies {
    test "org.spockframework:spock-grails-support:0.7-groovy-2.0" //<-- this one
  }
  plugins {
    test(":spock:0.7") {
      exclude "spock-grails-support"  // <---- this one
    }
  }
}

I've added these lines to my application's BuildConfig.groovy and after 
packaging the new version of plugin and adding it to app, app is deployed 
properly, as well as the one dimensional Array JSON is recognized and processed 
properly.

Hope my feedback will help.

Regards,
Anna.

OK, I've been able to reproduce h.romirer's error with a fresh 2.2.0 project, 
and it looks as though it doesn't occur with 2.1.x.

@Anna - Thanks for the feedback; are you experiencing these errors using a self 
compiled version, or the 0.7 version that's distributed through the plugin 
portal?
