Viewform

To recreate create a new eclipse view (plugin) as described here:

http://www.eclipse.org/articles/viewArticle/ViewArticle2.html

and put the attachment in the source. 

Make sure you state the view in plugin.xml:

      <view
            name="Newt View"
            icon="icons/sample.gif"
            category="TestPlugin"
            class="testplugin.views.JOGLTestNewt"
            id="testplugin.views.JOGLTestNewt">
      </view>

to see the view, you need to go to Window -> Show View -> Other... -> [category as described in plugin.xml] -> [view as described in plugin.xml]

In general the problem is another iteration of Bug 672 (https://jogamp.org/bugzilla/show_bug.cgi?id=672)
