flex - dpHibernate: serializerFactory not initialized by Spring -> NullPointerException on service access -

i trying dphibernate 2.0 rc6 running on apache tomcat 7.0.12 blazeds 4.0.0.14931, spring 3.0.5 , spring-blazeds-integration 1.5.0.m2

with following configuration server starts fine, want access service or rdsdispatchservlet via flashbuilder4 dcd getting nullpointerexception. seems serializerfactory not correctly injected dphibernate hibernateutil. did miss in configuration in remoting-config.xml?

org.dphibernate.utils.hibernateutil (snippet)

private static iserializerfactory serializerfactory; // should injected spring  public static sessionfactory getsessionfactory() throws hibernateexception {     return serializerfactory.getsessionfactory(); // null on call? } 

the remotingconfig.xml isn't needed, , appears what's causing problems.

typically, in spring configuration, hibernateutil class you've shown there isn't used (the springcontextserializerfactory returns sessionfactory ensure you're getting correct 1 spring session)

however, looks remotingconfig.xml file overwriting default settings, forcing use old hibernateutil approach, throwing npe.
