This is the XML Schema for the JDO configuration file. The root configuration element for JDO. Standard JDO PersistenceManagerFactory configuration properties. Vendor-specific properties are set using additional vendor-specific attributes and/or property elements. Vendor-specific properties. javax.jdo.listener.InstanceLifecycleListener instance configuration. There is one instance-lifecycle-listener element per listener instance. Only one instance of the listener class is supported in this configuration file. If multiple instances of the same listener class is required, then the API PersistenceManagerFactory.addInstanceLifecycleListener(...) must be used. If attribute "classes" is missing, all persistence-capable instances are observed; otherwise it is a comma- or whitespace-delimited list of persistence-capable classes whose instances will be observed. These are attributes corresponding to the standard properties defined in JDO. Any other attributes present, if unrecognized by a JDO implementation, may be silently ignored.
