Clean-room implementation of the Java Virtual Machine that has been specifically designed to run on devices with a small amount of system memory (from as low as 48KB). [Commercial]
A Java platform optimized for measurement, control and automation applications. The JControl Virtual Machine's design is as lean as it runs even on 8-bit microprocessors and hence it can compete with common 8-bit-systems.
Article covering the differences between ordinary Java development and EPOC Java development, such as designing for a smaller screen, lower resources and special deployment.
