This JSR will build upon the success of MIDP2 by enhancing the Profile with the following additions/changes:
* 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 MIDP3 will be backward compatibility with MIDP2 content 。
