Hi, > I will now look into the Eclipse model classes > for BPEL files to see whether I can use those to write out BPEL. You can also try use a BPEL object model representation used by one of the open source engines... We also wrote a BPEL Object Model for our undergrad final year project, but it is not 100% complete (lacks support for "pick") and it is not open source at the moment.
One another option would be to take the BPEL schema provided with the BPEL spec and code generate java classes for that using a data binding mechanism like XMLSchema or ADB.. thanks, Thilina >The > Eclipse BPEL Designer that Thilina spoke of also uses them, so it's > only a question of the quality of integration achievable with them. > > So instead of trying out all available libraries myself, I'd thought > maybe someone on this list could share some experiences.
