CORBA and File access in an applet

[Lin Shen]

Hi, I want to integrate CORBA in an applet. I got this exception when running appletviewer. Sandbox constraint. :-(

Exception in thread "Thread-2" java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThread)

Also, I want to use JFileChooser on the client side to allow users to submit files to the server. But surely this is not allowed in a normal applet with sandbox again.

I read a tutorial about Signed Applets at
http://java.sun.com/developer/onlineTraining/Programming/JDCBook/signed.html

But I am still not sure what should I do with CORBA.

Could anybody tell me how I can use JFilechooser and CORBA in an applet. Please give a step by step guide if you can.

Thanks very much.
