Netbeans 6.0 Preview can't find WsClientUpToDate (either can I)

I'm using NetBeans IDE 6.0 Preview (M9, build 070502) on XP

I'm building the StockClient from 4401_webservicessecurity

This is the error I receive:

wscompile-init:

C:\Sun\AppServer\samples\4401_webservicessecurity\webservicessecurity\samples\StockClient\nbproject\build-impl.xml:296: taskdefclass org.netbeans.modules.websvc.core.ant.WsClientUpToDate cannot be found

BUILD FAILED (total time: 0 seconds)

Here is the code the error is referring to:

<target name="wscompile-init" depends="init">

<taskdef name="wscompile" classname="com.sun.xml.rpc.tools.ant.Wscompile" classpath="${wscompile.classpath}"/>

<taskdef name="wsclientuptodate" classname="org.netbeans.modules.websvc.core.ant.WsClientUpToDate" classpath="${wsclientuptodate.classpath}"/>

Where can I find org.netbeans.modules.websvc.core.ant.WsClientUpToDate?
