Subject RE: Cayenne Generated Classes in Web Service API
Date Thu, 07 Jun 2007 20:37:11 GMT
Hi Michael,

Last year we had a Google Summer of Code project that provided an ROP
implementation via WSDL.  I mentored the project, but still have not had
the time to integrate it into Cayenne proper.  If you're interested, we
can look at what's necessary to complete that work.
