Thank you bfo81, that was indeed part of the problem. My apologies. Now this exception is gone but I am facing another error (javascript error): Error: Wp8Z.BRMU is not a function | Source File: http://127.0.0.1:8080/contacts/xmlhttp/icefaces-d2d.js | Line: 1 I think this one is related to Icefaces so I should post in their forum, but if anyone has already faced this problem and know how to solve it...
