The exception is not related to glassfish only, we also deployed on weblogic server and the icefaces inputfile failed in same way. Do you have any pointers or ideas what to change in icefaces upload servlet to make is use seam contexts and things correctly ? I'm willing to be the testsubject to recompile icefaces and test different approaches. Currently icefaces file upload works only if backing bean is session scoped and while doing upload, and no seam injection/bijection gets done etc. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4119991#...
