Hi all

I have been trying to get GroovyWS to work within grails but I cant seem to
resolve an issue. using GroovyWS 0.2, Java 1.5.1. The code below runs fine
in GroovyConsole, but once its intergrated into our main project within a
controller it fails to work. I have taken a look at both the WSClient source
and also CXF source but cannot figure out the null pointer exception!

class GroovyController {
def view = {
def proxy = new
WSClient("http://www.webservicex.net/stockquote.asmx?WSDL",
this.class.classLoader)
def quote = proxy.GetQuote('GOOG')
render ("proxy:- " + proxy + " quote:- " + quote)
}
}

returns "proxy:- groovyx.net.ws.WSClient@f6e45d quote:- null"

Log error is

It seems to create the stubs correctly, we can see them in the temp dir, but
the classes files are empty. It then falls over, with a not very helpful
error message.

Is this a CXF problem, is it a GroovyWS problem, is it a File Permissions
problem (full write permissions on the tempdir - so doubtful), is it a
classpath issue?

Any help gladly appreciated!!
Alex
