close

protected void close()

isEnabled

public boolean isEnabled()

返回：

true if an entityManagerFactory has started

newEntityManager

                                                java.lang.String configName)

Looks up all JPAConfigurationExtension implementations and applies them to the JPA configuration.

参数：

cfg - the Ejb3Configuration for this JPAConfig

configName - the name of the db configuration
