Thanks for the link to the Gilead forum. As per your discussion there, I removed this line from my gwt.xml file just to see what it would do:
<inherits name='net.sf.gilead.emul.java5.ejb3.Ejb3'/> To my surprise my hosted mode with the -noserver option started working. So, I'm a bit confused now. Do I need to keep this line in my configuration or not? What exactly does it do? I was under the impression that it was there to make GWT behave when it encounters EJB3 annotations (as per the instructions in the Stateless Mode doco) but clearly that's not the case. Does this make sense to you? Regards, Grigori PS: Thanks for the good work you've done/doing on Gilead. It is a great tool and is much appreciated.
