Re: exceptions: JESS,Protege,Applet : Help me please

Hello
I apologize, maybe I was not precise enough in my first message: the version of protege that I use is protege3.1.1 the JessTab12 and Jess70p2.
when I run my applet in HTML,the applet is loaded but with an empty combobox and I get the following exceptions
