The problem seems to be in the configuration of hibernate into spring : it works fine with | <property name="mappingResources"> | <list> | <value>Axxxx.hbm.xml</value> | <value>Bxxxxx.hbm.xml</value> | </list> | </property> | but not with | <property name="mappingDirectoryLocations"> | <list> | <value>classpath:</value> | </list> | </property> | And I have a lot of hbm.xml files...
