Hi,
I am new to Jena and am trying to use tdb to create a database. When I call
TDBFactory.createModel, I get the exception shown below. I have tried using
ModelFactory.createDefaultModel() and that works fine. I thought there might
be a versioning problem with external jars, but I believe I am using the jar
files that came with tdb in my build.
I would appreciate any suggestions!
Barbara
