DoJa

DoJa profile is a Java application environment specification for DoCoMo's i-mode mobile phone.

DoJa is based on the Java ME CLDC API that is defined in the Java Community Process (JCP). DoJa is a profile defined by NTT DoCoMo to provide communications and other input-output processing, user interface (GUI) and other application features/functions unique to i-mode, and extension libraries defined by individual phone terminal makers to add original functions. However, in contrast with other Java ME profiles like Mobile Information Device Profile (MIDP) or Information Module Profile (IMP), DoJa is not defined as a Java Specification Request (JSR), hence it is often called a "proprietary" Java ME profile.
