    - #### getObjectInstance

          public Object getObjectInstance(Object object,
                                          Name name,
                                          Context nameCtx,

                                   throws Exception

      This will be called by a JNDIprovider when a Reference is retrieved from a JNDI store - and generates the original instance
      Specified by:
        `getObjectInstance` in interface `ObjectFactory`
      Parameters:
        `object` - the Reference object
        `name` - the JNDI name
        `nameCtx` - the context
        `environment` - the environment settings used by JNDI
      Returns:
        the instance built from the Reference object
      Throws:
        `Exception` - if building the instance from Reference fails (usually class not found)

    - #### createReference

          public static Reference createReference(String instanceClassName,
                                                  JNDIStorable po)
                                           throws NamingException

      Create a Reference instance from a JNDIStorable object
      Parameters:
        `instanceClassName` - The name of the class that is being created.
        `po` - The properties object to use when configuring the new instance.
      Returns:
        Reference
      Throws:
        `NamingException` - if an error occurs while creating the new instance.

    - #### loadClass

          public static Class<?> loadClass(Object thisObj,

                                    throws ClassNotFoundException

      Retrieve the class loader for a named class
      Parameters:
        `thisObj` - Local object to use when doing the lookup.
        `className` - The name of the class being loaded.
      Returns:
