how to open jad or jar files

1. Write a simple Hello application. 2. Compile it. 3. Run it 4. Dump it in PDA. 5. See the output. one way to do this - I am guessing in J2ME environment public void makeCall() { ....... if (phone_number.length() == 0) return ; try { if (midlet.platformRequest ("tel:" + phone_number) == true) { // MIDlet must Exit before the call will be made ! } } catch (ConnectionNotFoundException e) { // Device don't support OutCalling ! Util.debug ("Error Making Outcall"); } }

You need a unzip program like winzip, I suggest you scan jar and jad files for viruses before you open them as they are 80% of the time infected.
