Sorry, I have to clarify my last post.
I would recommend to use the two level cache with the distributed cache 
as second level cache.
If you use OJB 1.0.5rc1:

<object-cache class="twoLevel">
     <!-- ObjectCacheTwoLevelImpl attributes -->
     <attribute attribute-name="applicationCache" attribute-value="jcs"/>
     <attribute attribute-name="copyStrategy" attribute-value="default"/>
     <attribute attribute-name="forceProxies" attribute-value="false"/>
</object-cache>

OJB 1.0.4:

<object-cache class="org.apache.ojb.broker.cache.ObjectCacheTwoLevelImpl">
     <!-- ObjectCacheTwoLevelImpl attributes -->
     <attribute attribute-name="applicationCache" 
attribute-value="org.apache.ojb.broker.cache.ObjectCacheJCSImpl"/>
     <attribute attribute-name="copyStrategy" 
attribute-value="org.apache.ojb.broker.cache.ObjectCacheTwoLevelImpl$CopyStrategyImpl"/>
     <attribute attribute-name="forceProxies" attribute-value="false"/>
</object-cache>
