Apparently "mappingDirectoryLocations" does not work when the configuration
files are packages in a jar of a bundle separately.
Nevertheless, mappingLocations works like this :
<property name="mappingLocations">
<list>
<value>classpath*:META-INF/org/apache/camel/example/reportincident/model/*.hbm.xml</value>
</list>
</property>
Unfortunalely, I have the following error now :
Is it a bug in javassist (3.9.0.GA) who cannot load the
org.hibernate.proxy.HibernateProxy class or a issue with felix classloading
?
remark : org.apache.proxy package is well defined in my MANIFEST file (and
of course expeorted by Hibernate 3.3.1.GA bundle)
