Subject Re: Use Jakarta's ObjectRelationalBridge (OJB) for your Struts ap p'spersistence layer
Date Fri, 21 Jun 2002 11:32:29 GMT
There's another tool / persistence layer I've been playing with called 
DMLDataAccess.  It seems to be fashioned somewhat after NeXT/Apple's 
EOF.  There's a GUI modeler tool, as well.  I believe the download is 
compiled for J2SE 1.4, although I think versions to support older JDK's 
are available.
