WebGL won't be supported by MSIE this year, maybe in 2012 or 2013. Therefore, it is not the way to go now. Moreover, JavaScript is still noticeably slower. Therefore, HTML5 + JavaScript + WebGL is a good solution but it won't fit in any projects, JOGL is still the best option on my view especially with NEWT and an AWT-less plugin in Java 1.7 that starts in less than 1 second :) Java rocks.
