Groovy

    http.get( path : '/ControllerName/Action', contentType : ContentType.TEXT) { resp, reader ->

            println "response status: ${resp.statusLine}"
            resp.headers.each { h ->
                println " ${h.name} : ${h.value}"
            }

        }
} catch (groovyx.net.http.HttpResponseException ex) {
    ex.printStackTrace()
    println ex.toString()

} catch (java.net.ConnectException ex) {
    ex.printStackTrace()
    println ex.toString()       
}       

Exception thrown

I finally found the problem: I changed The URI format. I added at the end of the URI a / , and I removed the / at the beginning of the path .

try {

        def http = new HTTPBuilder('http://localhost:8080/MyApplication2/')

        http.get( path : 'ControllerName/Action', contentType : ContentType.TEXT) { resp, reader ->

        println "response status: ${resp.statusLine}"
        resp.headers.each { h ->
            println " ${h.name} : ${h.value}"
        }

    }
} catch (groovyx.net.http.HttpResponseException ex) {
    ex.printStackTrace()
    println ex.toString()

} catch (java.net.ConnectException ex) {
    ex.printStackTrace()
    println ex.toString()       
}
