A Java mobile widget is a small chunk of Java ME code installed and operated by the Java On Device Portal (Java ODP) technology.
While other Java ODP solutions force developers to write mobile widgets using a proprietary scripting language, the Java ODP platform leverages Java ME technology. You can write widgets in pure Java and take advantage of Java's full capabilities, such as packages for Personal Information Management (PIM), location-based services (LBS), multimedia, and more.
