Hello,
I'm trying to learn OJB but am struggling getting a simple project to
run in Eclipse 2.1.3. I found what appears to be a good tutorial
entitled...
"Object-Relational Mapping with Apache Jakarta OJB" by Charles Chan
(http://www.onjava.com/lpt/a/2946) dated: 01/08/2003
I've built the clases and the project compiles. The error I cannot get
past is...
Property for key 'PersistenceBrokerFactoryClass' can not be found in
properties file.
As an FYI, I've successfully built the OJB rc6 from source. I can also
run the tuturial shell scripts in bin.
Here's how my Eclipse project is layed out...
