Grails - No class def found error when calling web service

问题

Updated to reflect new error message after changes

Howdy, I am trying to call a web service from Grails, but keep running in to errors.

Here's what my class looks like:

import groovyx.net.ws.WSClient

...

    def serviceUrl = "http://www.w3schools.com/webservices/tempconvert.asmx?WSDL"
    def proxy = new WSClient(serviceUrl.toString(), this.class.classLoader)
    serviceResult = proxy.FahrenheitToCelsius("80")
    println serviceResult

...

I am encountering a grails runtime exception:

Error 500: Executing action [index] of controller [myPackage.myController] caused exception: java.lang.NoClassDefFoundError: org/apache/cxf/endpoint/Client

Have been trying to troubleshoot, but have been unable to find any helpful resources. Any help or suggestions on how to remedy would be much appreciated.

Thanks.

You missed the new operator it looks like:

def proxy = new WSClient(serviceUrl.toString(), this.class.classLoader)
