# Java Platform Micro Edition ## Identification Java Platform Micro Edition is a family of Java configurations and profiles for constrained and embedded devices. The notebook connects CDC/PBP/Xlets and Blu-ray Disc Java with MIDP/LCDUI/MIDlets and JAD/JAR deployment on historical mobile systems. ## Notebook evidence - [[Scanned_20260730-1659#PDF page 48 — Blu-ray Disc Java, CDC, Xlets, GEM, and RMI|PDF page 48: Blu-ray Disc Java, CDC, Xlets, GEM, and RMI]] — The page accurately traces BD-J into the Java ME/CDC ecosystem. Blu-ray’s ROM2 format adopted BD-J and UDF 2.5, while Oracle’s CDC documentation describes Xlets as managed applications suited to embedded devices such as set-top boxes and PDAs. GEM generalized MHP-style interactive television APIs across receiver platforms. The page was uncovering a neglected continuity: **optical-disc menus were networked embedded applications**, not merely video navigation. - [[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 [[Blu-ray Disc Java|Blu-ray Disc Java]] · [[Connected Device Configuration|Connected Device Configuration]] · [[Globally Executable MHP|Globally Executable MHP]] · [[Infrared Data Association|Infrared Data Association]] · [[Java Application Descriptor|Java Application Descriptor]] · [[Java Archive|Java Archive]] · [[Java Platform Standard Edition|Java Platform Standard Edition]] · [[Java Remote Method Invocation|Java Remote Method Invocation]] · [[Liquid Crystal Display User Interface|Liquid Crystal Display User Interface]] · [[MIDlet|MIDlet]] · [[Mobile Information Device Profile|Mobile Information Device Profile]] · [[Multimedia Home Platform|Multimedia Home Platform]] · [[Personal Basis Profile|Personal Basis Profile]] · [[Personal Information Management|Personal Information Management]] · [[Windows CE|Windows CE]] · [[Xlet|Xlet]].
