MIDP 3.0
             About more that an year ago, while reading the specs of MIDP 3.0 (JSR-271) a strong feeling came to my mind that it will of course be a promise to the mobile world to be in pace with utilizing of the power of the high end gadgets where it is implemented! Java Micro Edition is still growing and we could expect more in the upcoming days! For developers like me, it gave an impression that JME is in its limits, but have to realize that there is still a long way to go.
The key Features of MIDP 3.0 include
-> Enable and specify proper behavior for MIDlets on each of CLDC, CDC, and OSGi, for example:
   o Enable multiple concurrent MIDlets in one VM
   o Specify proper firewalling, runtime behaviors, and lifecycle management issues for MIDlets
   o Enable background MIDlets (e.g. UI-less)
   o Enable auto-launched MIDlets (e.g. started at platform boot time)
   o Enable inter-MIDlet communications
-> Enable shared libraries for MIDlets
-> Tighten spec in all areas to improve cross-device interoperability
-> Increase functionality in all areas. E.g.
   o Improve UI expressability and extensibility
   o Better support for devices with larger displays
   o Enable MIDlets to draw to secondary display(s)
   o Enable richer and higher performance games
   o Secure RMS stores
   o Removable/remote RMS stores
   o IPv6
   o Multiple network interfaces per device
-> Specify standard ways for doing MIDlet provisioning through other means (e.g. OMA (SyncML) DM/DS, Bluetooth, removable media, MMS, JSR-232, etc.)
-> Extensive device capabilities query
-> Localization & Internationalization (if appropriate, integrating/augmenting JSR-238 as needed)
A key design goal of MIDP 3.0 will be backward compatibility with MIDP 2 content.
I am looking forward for the announcement of first set of devices that do support JSR 271.
