Interface EJBLocalObject

Contents

  • public interface EJBLocalObject
    The EJBLocalObject interface must be extended by all enterprise beans' local interfaces. An enterprise bean's local interface provides the local client view of an EJB object. An enterprise bean's local interface defines the business methods callable by local clients.

    The enterprise bean's local interface is defined by the enterprise bean provider and implemented by the enterprise bean container.

    Enterprise beans written to the EJB 3.0 and later APIs do not require a local interface that extends the EJBLocalObject interface. A local business interface can be used instead.

    Since:
    EJB 2.0

        EJBLocalHome getEJBLocalHome()
                      throws EJBException
        Obtain the enterprise bean's local home interface. The local home interface defines the enterprise bean's create, finder, remove, and home business methods that are available to local clients.
        Returns:
        A reference to the enterprise bean's local home interface.
        Throws:

      • getPrimaryKey

        Object getPrimaryKey()
              throws EJBException
        Obtain the primary key of the EJB local object.

        This method can be called on an entity bean. An attempt to invoke this method on a session bean will result in an EJBException.

        Note: Support for entity beans is optional as of EJB 3.2.

        Returns:
        The EJB local object's primary key.
        Throws:
        EJBException - Thrown when the method failed due to a system-level failure or when invoked on a session bean.

        boolean isIdentical(EJBLocalObject obj)
             throws EJBException
