Scarbo Modeler allows you to easily defines processes that can consume webservices, execute Groovy scripts, send mails… and the export them as executable XPDL-based processes on Scarbo runtime (Bonita 4 + extensions).

Last improvements were focused on usability, so that once Scarbo downloaded, you need less than 5 minutes to design and execute a workflow that calls webservices. You don't have any reason for not trying it now. Then get it from http://scarbo.ow2.org and give some feedback on Scarbo forum!

Thanks for reading, the Scarbo Team.
