public java.lang.Object getObjectInstance(java.lang.Object obj,
                                          javax.naming.Name name,

Creates a destination. The destination is created using destination attributes obtained using name and nameCtx and table attributes obtained using environment.

Specified by:

getObjectInstance in interface javax.naming.spi.ObjectFactory

Parameters:

obj - a javax.naming.Reference indicating the destination class

name - the location containing the destination attributes

nameCtx - a javax.naming.directory.DirContext containing the following destination attributes at the above location:

• AQjmsConstants.LDAP_OWN_ATTR
• AQjmsConstants.LDAP_NAM_ATTR
• AQjmsConstants.LDAP_PTR_ATTR
• AQjmsConstants.LDAP_GEN_ATTR:
  • "queuetype" (AQQueueProperty.NORMAL_QUEUE or AQQueueProperty.EXCEPTION_QUEUE)
  • "maxretries"
  • "retryinterval"
  • "rentention" (retention time)

environment - used to create an InitialDirContext containing the following table attributes at the location indicated by the above AQjmsConstants.LDAP_PTR_ATTR attribute:

• AQjmsConstants.LDAP_NAM_ATTR
• AQjmsConstants.LDAP_GEN_ATTR:
  • "payloadtype"
  • "multiconsumers" (true for a topic, false for a queue)

Returns:

a new destination object, or null if:

• obj is invalid,
• looking up the provided name in the provided nameCtx fails,
• looking up the table attributes with the context created using environment fails, or
• any of the LDAP_*_ATTR attributes are not found

Throws:

JMSException - if a destination is not created for any reason other than those listed above (which result in a null return value).
