Project Summary
COPPER (COmmon Persistable Process Excecution Runtime) is a high performance workflow engine, that persists the workflow instances (process) state into a database. So there is no limit to the runtime of a process. It can run for weeks, month or years. In addition, this strategy leads to crash safety.
The power of COPPER is a) that it uses Java as a description language for workflows, not some weird XML language, and b) that whenever a workflow is persisted into database the full stack frame with the state of all local variables and member fields gets persisted, too, so when the workflow resumes later on it can continue where it was paused (ie. it's a full continuation server).
In a Nutshell, COPPER Java workflow engine...
