The IllegalAccess error suggests that you're running in an environment with a SecurityManager enabled that prevents your code from accessing private fields, eg. an application server. You can either grant your application that right (see the security manager documentation). Or you can direct OJB to make the field accessible first before using it by changing the used PersistentField implementation in OJB.properties to PersistentFieldPrivilegedImpl. Or - if the field in question has accessors - use bean access instead by changing it to PersistentFieldIntrospectorImpl or to PersistentFieldAutoProxyImpl (which uses bean access or direct (privileged) access depending on what's available).
