Can't create engine: a new feature with Java Plug-in 1.6.0-beta2 ?

Question

Hi
We use Java.Help embedded in an applet to check small pieces of text. The whole things works without problems until recently: the full text search does not work anymore when the applet is called with http, it does work when it is called as File in the browser. I suspect the automatic upgrade of JRE 1.6.0-beta2 is related to this.
I have tried to put
grant codeBase "http://www.unifr.ch/dokpe/procedures/procall.jar" {
permission java.security.AllPermission;
}in my security file but it does not change the problem.
The url is http://www.unifr.ch/dokpe/procedures/index.htm
Thanks for any help

I have found a thread in another forum with the same problem, I think: http://forum.java.sun.com/thread.jspa?forumID=42&threadID=616794
One more point: I have remove the Plug-in 1.6.0-beta2 and use now the 1.5.0_06 version: I can use the full text search without problem !
any idea someone ?
