I think this is maybe a problem with the version of hibernate you are using. As part of this simplified configuration feature, the assembler is going into the metadata for hibernate and it seems like the protection-level on that method has changed or is different in the version you are using than the one we compiled against. We are using 3.2.5 I believe.
You should not need to change any configuration as it is compatible with the old format. You can remove the metadata section entirely and it will generate the id properties and lazy=true associations for each hibernate association. You can then add assoc tags as needed to change the defaults. Any associated destinations which are not defined are not directly accessible via clients though they are created so you don't have to declare all destinations in your model - just the ones you use fill or getItem calls on. Back to the original error, I guess the other spring configuration you were using was generating some proxy class which did not extend HibernateAssembler? What version of spring are you using?

My assember is then a bean in the Spring container. Obviously something is wrong with this bean because if I force CGLib proxies in my container (to avoid the proxy cast error; even though my derived assembler implements an interface) I get the following error: 17:45:18,606 ERROR [STDERR] **** MessageBrokerServlet failed to initialize due to runtime exception: Error: java.lang.IllegalAccessError: tried to access method org.hibernate.persister.entity.AbstractEntityPersister.getEntityMetamodel()Lorg/hibernate/tuple/entity/EntityMetamodel; from class flex.data.assemblers.HibernateType at flex.data.assemblers.HibernateType.start(HibernateType.java:247) at flex.data.assemblers.HibernateAssembler.start(HibernateAssembler.java:216) Would I need to update my data-management-config.xml file for 2.6? I am under the impression that it can be greatly simplified (from 2.5.1 config) by removing the hibernate object mappings; but it doesn't need to for backward compatibility. I am using hibernate config files, not annotations, and an example destination I have (one with no relationships) is: <destination id="testycle.hibernate"> <adapter ref="java-dao" /> <properties> <factory>spring</factory> <source>TestCycleBean</source> <use-transactions>true</use-transactions> <scope>application</scope> <metadata> <identity property="id"/> </metadata> <network> <session-timeout>0</session-timeout> <paging enabled="false" pageSize="10"/> <throttle-inbound policy="ERROR" max-frequency="500"/> <throttle-outbound policy="REPLACE" max-frequency="500"/> </network> <server> <hibernate-entity>com.xxx.ics.dto.TestCycle</hibernate-entity> <update-conflict-mode>PROPERTY</update-conflict-mode> <delete-conflict-mode>OBJECT</delete-conflict-mode> <fill-method> <name>fill</name> <params>java.util.List</params> </fill-method> <fill-configuration> <use-query-cache>false</use-query-cache> <allow-hql-queries>true</allow-hql-queries> </fill-configuration> </server> </properties> <channels> <channel ref="my-rtmp"/> </channels> </destination> and the simple bean definition is: <bean id="TestCycleBean" class="com.xxx.ics.assembler.MyHibernateAssembler"/> I commented everything else out in my data-management-config.xml. --- In flexcoders@yahoogroups.com<mailto:flexcoders%40yahoogroups.com>, Jeff Vroom <jvr...@...> wrote: > > I am thinking your spring configuration must be wrapping the > HibernateAssembler in a proxy.
