Open Source Workflow Engines in Java

TobFlow (Total Object Base and Flow or the Object Flow) is an internet application platform to manage forms and workflows. It is made of an engine which manages the user interface (forms) and the scheduling of tasks (workflows) based on object model descriptions. The rationale of TobFlow is to propose a true document workflow tool, which, right from the design phase, combines the document approach (forms to fill in) and the process approach (sequence of tasks to fulfill a business objective). The solution is based on the notion of objects (i.e. information sets) that are defined both by the way they are presented to users (forms and views) and by their life sequence (workflow process).
