security problem?

hi all,

i'm trying to create jabber chat client, and i've already posted some of my questions there ( http://forum.java.sun.com/thread.jspa?threadID=5176137 ), but this is totally new problem.

this is what i've done so far:

1) i've created normal .awt GUI for my chat, one button and 2 text fields

2) i've imported smack.jar files, which is acctually chat classes

3) i've created jar file out of my project

4) i've signed it, it worked

now - before my applet runs - it askes me "should you trust this publisher...", and i say yes, and that's all fine, but then, when my applet tries to connect to server, i get this error message in my applet:

"access denied (java.util.PropertyPermission java.home read)"

what does it mean?

i've tried to mess around the "java.policy" file, but with no success.

even worse, i don't want this to work "for my computer only", this is chat client, it should run on all computers which visits my site.

where am i making the mistake?

any info is most welcome,

thanks,

dootzky
