Hi guys!
On the page 26 the MIDP spec states:

How a MIDlet is bound to a specific domain?
Thanks for any reply!

Hello,
As far as my understanding of this subject goes, MIDlet suites complying with MIDP 1.0 run in MIDP 2.0 compliant devices in the 'Untrusted Domain',
which is a 'Sandbox' environment that restricts access to protected resources, APIs,...
MIDP 2.0 signed MIDlets, get assigned to some 'Protection Domain' on a MIDP 2.0 compliant device, in a device specific manner.. So as far as i know, a number of 'Trusted' domains could be defined for different MIDlet suites requesting different APIs, using the 'MIDlet-Permissions' entry in the JAD or in the manifest of the JARed App.
If anyone has a better understanding of 'Protection Domains' please explain.
Hope that helps!
