Subj : Security Problem To : netscape.public.mozilla.jseng From : Keno Albrecht Date : Wed Jul 07 2004 11:24 am Hello, I'm writing a Mozilla Extension using LiveConnect to access my own classes. Since I didn't find out where to put my classes (except the jre/classes directory which is not useful since I want them somewhere in the Mozilla directory to install them with xpi later), I use a URLClassLoader to access/load them. Now, the problem is that there seems to be a rather restrictive SecurityManager - I cannot read/write local files, open connections etc. Also, Frames are marked with an "Applet-Flag". Well, I do not wrote an Applet, this is an Extension directly linked into XUL/.js Code, so can I avoid these security restrictions somehow? Thanks, Keno .
