[json-lib-user] StringMetaClass Problem

[Andrew S. <str...@gm...>]

Hello,

I'm having a problem using the JsonGroovyBuilder.  I'm using Json-lib
2.2and Groovy
1.5.1, they are declared in my POM like so:

<dependency>
         <groupId>net.sf.json-lib</groupId>
         <artifactId>json-lib</artifactId>
         <version>2.2</version>
         <classifier>jdk15</classifier>
</dependency>

<dependency>
         <groupId>org.codehaus.groovy</groupId>
         <artifactId>groovy-all</artifactId>
         <version>1.5.1</version>
</dependency>

Here's the snippet from my groovy script where I try to do the json
creation:

def builder = new JsonGroovyBuilder();

    if (searchResponse != null) {
        def orders = builder.orders{
            for(ord in ords){
                order{
                    tsrNumber = ord.getTsrNumber()
                    tsoNumber = ord.getTsrNumber()
                    ccsd = ord.getCcsdNumber()
                    status = ord.getStatus()
                }
            }
        }
    }

I get the following exception:

I checked the json-lib source browser for StringMetaClass and noticed a
difference between revision 1.1 and 1.2, you can see it here:
http://json-lib.cvs.sourceforge.net/json-lib/json-lib/src/main/groovy/groovy/runtime/metaclass/java/lang/StringMetaClass.groovy?r1=1.1&r2=1.2.

Notice that the constructor that took a MetaClassRegistry and Class is now
gone...and that appears to be the constructor that Groovy is trying to
instantiate.  Anyone have any idea why this is happening, if there is a fix
for it, or how I can get around it?
