Geoserver, Groovy and REST advice

Rate this Message:
Hi,
I've made a few posts along these lines recently and now I've come to a new problem. I'm trying to create a REST client for configuring GeoServer using Groovy. Unfortunately I'm quite new to Groovy so that might be why I'm having trouble. I've got a createWorkspace method as follows:
def createWorkspace(def wsName, def geoserverUrl, def user, def pass){ // setup the restclient def rest = new RESTClient(geoserverUrl)
// do the authing rest.auth.basic user, pass // post it
def res = rest.post( path: "geoserver/rest/workspaces", requestContentType: XML,
body: "<workspace><name>${wsName}</name></workspace>" )
} This actually works in that it creates a workspace in geoserver, but it also throws up a number of exceptions because it fails to parse the result (shown below). I'm not wondering - is this GeoServers fault or is it a problem with my code? Has anybody had any experience with this?

Perhaps the REST API could accommodate clients like this one by adding some dummy content-type (text/plain?) to empty responses.

Hi,
Just thought you might be interested in what's been going on with the Groovy people on this issue. It seems to me that this is all GeoServers fault for not returning a content-type header. There seem to be some debate on whether this is required by the REST spec?
