Java Developer's Library

Welcome to the Java™ Developer's Library (JDL). The library supports devices up to Java Runtime 2.0.0 for Series 40 and Java Runtime 2.3 for Symbian.

Java Platform, Micro Edition (Java ME) is the mobile-optimized version of the Java platform and the most widely available runtime on mobile devices. It offers an excellent opportunity to take application ideas to the mass market.

To enable application development, Nokia provides software development kits (SDKs) for the Series 40 and Symbian platforms that integrate with the most popular Java IDEs. Whether you want to take advantage of Nokia's advanced Java APIs or build applications for the widest range of mobile Java devices, Nokia's support for Java technology is ready to work for you.
