It means that an external package that OJB depends on (Jakarta Commons
Pool in this case) is not present in your classpath.

Hi,
In version 0.9.5 it was possible to use wildcards in where-criteria.
Example :
criteria.addEqualTo(productGroup.groupName,pro*gro?p 1);
This seems not to work anymore in 1.0rc4 ?
Is it a bug ?
Thanks,

Hello,
All the JAR I need are in the classpath.
When I run OJB from a servlet it works well but when I run it from a main() method
this error occurs.
There is no differences between them.
That's a bit strange!

Hi,
it must be some classpath problem...
note that all jars deployed in WEB-INF/lib are automagically added to
the classpath by the web server, however if you use OJB in a standalone
application, you have to add each jar file to the CLASSPATH and not only
the directory where they are located.
Hi,
I try to map two classes Address and PersonAddress (a subclass of Address)
using the joined table per sublcass strategy. This is my mapping:

Hello Peter,
I've worked with inheritance and all works well (with some help of the mailing
list). You shoud look at my past post or you should post your complete java code.

Just one question: is OJB 0.9.5 OK with JDK 1.4 (because I have just changed it)??

Have you tried criteria.addLike()?

I do not think so.

Hi Peter,
You might want to try declaring PersonAddress as an extend in the
class-descriptor for Address (see the Advanced OR Mapping Tutorial on
the website). I haven't tried this myself, but I was reading that
section of the tutorial last night and I think an extent might solve
your problem.

Well Peter,
You've exhausted my knowledge. I would guess it is a bug /
incompatibility with using the extent class along with the super

Any ideas / comments from the contributors?
