XBAYA - A Graphical Workflow Composer for Web Services is a graphical client program, developed as a Grid Web Services Project (xgws), at the Extreme! Labs of Indiana University. It does workflow composition, monitoring, and more, by providing a GUI to compose workflows from Web Services described in WSDL. The composed workflow can be exported to workflow languages, where BPEL and Jython Scripts are supported currently.
