Well -
The OJB jar is not in the web-app classpath.
I have the jar in the EJB classpath.
I have removed it and I get the desired effect...the app server can't
find the PersistenceBroker class.
When I use ANY version of > 1.0.1, I get this exception.

you mentioned that you use a remote session bean, so your client need
org.apache.ojb.broker.util.collections.RemovalAwareCollection
class in classpath too, because the serialized objects with 1:n
references use this class to store the referenced objects. How does your
webApp get access to this class? Maybe you put only this class object in
the classpath of your webApp.

strange, seems that you have two different versions of class
org.apache.ojb.broker.util.collections.RemovalAwareCollection
in your classpath (this is what the exception asserted).
Are you really sure that both OJB jars (web-app and appServer) are the
same? Could it be the case that the webApp or the appServer use some
kind of "jar-cache" that still use an outdated jar?

Armin

I have NOT changed my OJB.properties file, could this have

Without looking to deeply into the stacktrace you sent;
it is always recommended to upgrade OJB.properties and repository
between releases. Please diff your old property file against the
reference version from 1.0.3 and check if you need to adjust anything.
For 1.0.1 => 1.0.3 this is especially true if you are using the ODMG
API.
(Also not the required change of auto-* repository settings
for ODMG in v1.0.3 -- see repository.dtd for full details.)
