new OJB user: newOQLQuery() no such method error

[Robert Smol <ro...@dhl.com>]

Hello,
I am trying to setup OJB for my little project. I started with small
class performing update and select from db. Update is working, select is
giving me error:

Exception in thread "main" java.lang.NoSuchMethodError:
org.odmg.Implementation.newOQLQuery
()Lorg/apache/ojb/odmg/oql/EnhancedOQLQuery;
        at gts.ODMGTest.loadData(ODMGTest.java:56)
        at gts.ODMGTest.main(ODMGTest.java:94)

I tried to read through Javadoc and I can see that this should be
implemented by class implementing Implementation interface. I do not
know how the OJB.getInstance(); code works. Do I need to have some
special implementation class to make it works? Am I missing something
obvious? I am just a mediocre Java coder interested in this tech. I am
quite desperate.

Here is source code of my test.
