This seems like a problem with your build classpath settings in eclipse.
Try to load OJB from CVS HEAD with eclipse. In CVS we have the eclipse .project and .claspath files that eclipse needs to build OJB.

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...
