Process Filter error

In trying to use the ProcessFilter I came across an error

java.lang.NoClassDefFoundError: w3c/jigsaw/resources/OutgoingElement
        at w3c.jigsaw.resources.FilteredResource.applyIngoing(FilteredResource.java:179)
        at w3c.jigsaw.resources.FilteredResource.perform(FilteredResource.java:253)
        at w3c.jigsaw.http.Client.processRequest(Client.java:290)
        at w3c.jigsaw.http.Client.loop(Client.java:500)
        at w3c.jigsaw.http.Client.runConnection(Client.java:572)
        at w3c.jigsaw.http.Client.run(Client.java:555)
        at java.lang.Thread.run(Thread.java)

I can't find an 'OutgoingElement' in the JDK or Jigsaw API.  Is there
a piece missing from the code I downloaded, or can I find this class
somewhere else, or, can I change this to something else that will 
work.
