IBM Websphere Everyplace Custom Environment is a complete production-level runtime environment for the deployment of embedded applications in closed systems where J2ME compliance is not required.

The environment provides engineering control for the deployment of embedded Java applications by delivering a compact, reliable, and high performance tailored platform built on the IBM J9™ virtual machine for a specific application. It allows the device stack to be optimized for system constraints and application service demands, and supports deep embedded techniques to reduce memory footprint.

IBM J9™ virtual machine has been optimized for a range of standard reference platforms – critical when every byte of memory is tracked and the need for application performance is paramount. IBM Websphere Everyplace Custom Environment offers developers maximum flexibility and ultimate control over system resources.
