Scarbo Modeler 1.1 has been released with major usability improvements! Its codename is "The Critical Coypu".
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.
