all,
I use Weblogic as my EJB server.The example statefulSession can work
well,but when I change Client.class to a applet,it can't work.
The following is error information:

The .html file source is :
<BODY>
<APPLET CODE="examples.ejb.basic.statefulSession.Client_A.class"
archive="/weblogic/classes/applets.jar,/weblogic/lib/weblogicaux.jar"
WIDTH=430 HEIGHT=270></APPLET>
</BODY>
How can I resolve the error?
Thanks in advance.
