COPPER 2.1.1

High-performance, Java-based workflow engine
COPPER (COmmon Persistable Process Excecution Runtime) is a free and open-source workflow engine, which persists the workflow instances (process) state into a database.

With COPPER, there is no limit to the runtime of a process. It can run for weeks, month or years. Also, this strategy leads to crash safety.

Some advantage of the COPPER utility are:
· any Java developer is able to design workflows
· many Java libs can be integrated within COPPER
· many Java tools, like IDEs, can be used
· with COPPER your productivity will be increased when using a workflow engine
· using Java solutions will protect your investment

COPPER is a cross-platform utility capable of running on any operating system that comes with Java support (e.g. Mac OS X, Windows, Linux).

Main features:

  • High Performance Workflow Engine for Java
  • Open Source
  • Describe Workflows in Java
  • Running in any container, e.g. Spring
  • Run multiple engines within one java process if needed
  • Dependency Injection for Workflow instances
  • Change Workflows dynamically at runtime
  • Transient or Persistent Workflows supported
  • Support for long running persistent Workflows, runnning for days, months, years
  • Support for multiple RDBMS
  • NoQueue overflows (as lang as the data fits into the underlying database)
  • Distributed Execution on multiple coupled engines enables
  • Load Balancing
  • Redundancy
  • High Availability (requires a high available DBMS, e.g. Oracle RAC)
  • Fast and generic Audit Trail
  • Support for short running transient Workflows
  • Minimal processing overhead enables real time processing
  • Enables asynchronous waits for one or more responses from partner system calls
  • Supports early responses (response arrives before wait is called)
  • Supports any (unique) correlation id
  • Asynchronous processing enables processing of many thousand workflow instances in parallel without facing thread count limitations
  • Management & Monitoring via JMX
  • Configurable amount of processor pools with a dynamic count of worker threads
  • Logging in COPPER uses slf4j, which enables seamless logging integration into your container/environment
  • Tested with java version 6 and version 7
  • javadoc documentation for the engine API available
  • Enables debugging of Workflows with any Java Debugger
