# Java Archive ## Identification Java SE is the general desktop/server platform; Java ME targets constrained/mobile/embedded devices. MIDP is the mobile profile; LCDUI is its display toolkit; a MIDlet is its application unit; JAR contains code/resources and JAD describes deployment metadata. PIM APIs, IrDA, SD cards, Bluetooth, BlackBerry, Palm, and Windows CE are the surrounding pre-smartphone device ecosystem. `JAI` most likely means Java Advanced Imaging but the checkbox context is uncertain. ## Notebook evidence - [[Scanned_20260730-1659#PDF page 49 — Java ME mobile-platform lineage and deployment files|PDF page 49: Java ME mobile-platform lineage and deployment files]] — This page extends the lineage from Java SE RMI to constrained mobile stacks. Oracle documentation defines Java ME as configurations plus profiles, MIDP as the mobile profile, LCDUI as its display toolkit, MIDlets as applications, and JAD/JAR as descriptor/archive deployment files. The references to PIM, IrDA, SD cards, Bluetooth, BlackBerry, Palm, and Windows CE reconstruct the pre-smartphone interoperability layer from which later app ecosystems emerged. ## Relationships and overlays The source places this record in an evidence cluster with [[Infrared Data Association|Infrared Data Association]] · [[Java Application Descriptor|Java Application Descriptor]] · [[Java Platform Micro Edition|Java Platform Micro Edition]] · [[Java Platform Standard Edition|Java Platform Standard Edition]] · [[Liquid Crystal Display User Interface|Liquid Crystal Display User Interface]] · [[MIDlet|MIDlet]] · [[Mobile Information Device Profile|Mobile Information Device Profile]] · [[Personal Information Management|Personal Information Management]] · [[Windows CE|Windows CE]].
