LIBlets Shareable components that one or many midlets can use Expose a set of API’s and resources that a MIDlet can use Inert code and resource fragments that only execute within a MIDlet context. Save static footprint size by preventing LIBlet code packaged in each MIDlet. Potentially reduce download times for applications
