I have also attached my plug-in.xml and Manifest.MF files.
<p><a href="http://n3.nabble.com/file/n112549/plug-in.xml" target="_top">plug-in.xml</a></p>
<p><a href="http://n3.nabble.com/file/n112549/Manifest.MF" target="_top">Manifest.MF</a></p>
I will keep trying to make this work but if anyone has any ideas or has any experience with developing this plug-in please let me know! Even a small hint at what this could be would be great :)
Thanks everyone!
