Hi I'm a little new to netbeans in terms of using it for web based operations so I was following a tutorial on web services and I'm having trouble deploying a web service on GlassFish Server 4.0

My error in build-impl.xml file is

<target if="netbeans.home" name="-run-deploy-nb">
<nbdeploy clientUrlPart="${client.urlPart}" debugmode="false" forceRedeploy="${forceRedeploy}"/>
</target>

The error states:

In-place deployment at C:\...(path to file)......\build\web
Initializing...
deploy?DEFAULT=C:\...(path to file)......\build\web&name=AffableBean&contextroot=/AffableBean&force=true failed on GlassFish Server 4.0
