There are a number of projects underway to create tools that allow developers to visually assemble Web services into collaborative and transactional business flows using the BPEL4WS standard.
These tools vary in the level of visual abstraction used to generate and edit BPEL code and in the development environment in which they are hosted (e.g. standalone versus eclipse plug-in, etc). Some of the notable BPEL editors are:
 IBM's BPWS4J Editor
 Collaxa's BPEL Wizard
 Iopsis's iNsight
