Subject: [Discuss] how to obtain privileges for calling JAR function?
Message-ID: <49230DB1.6050000@gmail.com>

hi all

i already tried at dev-extensions mailing list, which until now didnt 
solve my problem

i wanna create a firefox 3.* extension which currently is structured 
like this
chrome
|---content
       |----- firepastry.xul
       |----- scripts
                   |-------- overlay.js
chrome.manifest
components
|----------Pastry.js
install.rdf
lib
|-------FreePastry-2.0_04.jar


within components/Pastry.js i try to build this 
(http://freepastry.org/FreePastry/tutorial/src/lesson1/DistTutorial.java) 
example but just with javascript
creating the needed classes and invoking library functions seem to work, 
but if i try to

PastryNodeFactory factory = new SocketPastryNodeFactory(nidFactory, 
bindport, env);  /// the JS code would be a bit longer, so i post only 
the java example equivalent

i get an exception
java.security.AccessController.doPrivileged(Native Method)
sun.plugin.liveconnect.SecureInvocation$2.run(SecureInvocation.java:140)
java.security.AccessController.doPrivileged(Native Method)
sun.plugin.liveconnect.SecureInvocation.CallMethod(SecureInvocation.java:121)
sun.plugin.navig.motif.AThread.handleRequest(Native Method)
sun.plugin.navig.motif.AThread.JNIHandleLoop(AThread.java:40)
sun.plugin.navig.motif.AThread.run(AThread.java:32)

i think its because it of maybe creating a serversocket and thus 
throwing a securityexception

now my question is: how can i obtain the needed privileges to use the 
library correctly? what are the possibilities? signing the JAR didnt help
and: is my interpretation of the exception/failure condition correct or 
is the problem a completely different one, as far as you can see?


thx all
