While not an answer to your question, Aptana supports jQuery and I actually like Aptana better than JSEclipse. I used JSEclipse for a long time before switching to Aptana. http://www.aptana.com/products/ The "Community Edition" is free and offers all the basic functionality you could want. -Dan PS - I'm in no way affiliated with Aptana, just a user of their product.
