Question

GroovyWS is a framework which is internally using CXF. I want to make a request as follows:

<param2 xsi:type="ns2:Map">
    <item xsi:type="ns2:Map">
        <key xsi:type="xsd:string">param1</key>
        <value xsi:type="xsd:string">param2</value>
    </item>
</param2>

Currently I am trying to do this from a grails service as following:

def proxy = new WSClient("http://xyz", this.class.classLoader)
proxy.initialize()

proxy.client.invoke("call", new HashMap<String, String>())

Which gives

javax.xml.bind.JAXBException
class java.util.HashMap nor any of its super class is known to this context.

I even tried [:] and stuff but do not get it working.

Answer 1

Well, it’s been a while since I did something like this, but I seem to remember that CXF-generated clients had a method called “create”, similar to:

def mapObject = proxy.create( "ns2.Map" );

Give that a try and see if the mapObject has the methods or members you’re expecting.
