JavaTM Platform, Micro Edition
Connected Device Configuration
Consumer and embedded device platforms
< The Connected Device Configuration (CDC) technology, defined through the JavaTM
Specification Request (JSR) 36 and JSR 218 specifications, is a standards-based framework
for building and deploying applications that can be shared across a range of network-
connected consumer and embedded devices. Users benefit from the compatibility and security of
Java technology. Developers benefit from the safety and productivity of the Java programming
language and the rich APIs in the Java platform. And enterprises benefit from using network-based
applications that extend the reach of business logic to mobile customers, partners and workers.
Goals of CDC Elements of the Java Platform, Micro
CDC has two principal goals: Edition (Java ME, formerly J2METM)
