Enqueuing XMLType

Question

I am trying to enqueue an XMLType value and have some questions.
I tried to use a JMS ObjectMessage. But when I tried to setObject with the XMLType value, I get the following error:
oracle.jms.AQjmsException: JMS-157: IO Exception
Caused by: java.io.NotSerializableException: oracle.jdbc.driver.T4CConnection
I looked at the demos that came with the Oracle installation and found one which uses the AdtMessage with XMLType values. However, when I looked at the Javadoc for the classes related to the AdtMessage type, there were notes indicating that the methods would be deprecated sometime in the future.
So, my questions are:
1. Is using any of the JMS Message types out of the question for XMLType? If not, which Message type should I use? And what payload type should I use for the queue table? I know that I can convert the value to a byte array, but I was hoping to still persist the value as an XMLType. Is that possible? I've been trying to locate the Javadoc for the oracle.AQ packages, but have been unable to.
2. If I do need to use the AdtMessage type, should I be concerned about the deprecation warnings? Is it the case that these methods will merely be replaced by others? Or that support for this functionality will be going away?
Thanks so much for your help.

Code i used to complete the jms option with xml
dbms_aqadm.create_queue_table(
queue_table => 'change_q_tab',
multiple_consumers => FALSE,
storage_clause => 'TABLESPACE &x_tablespace',
sort_list => 'PRIORITY,ENQ_TIME',
message_grouping => DBMS_AQADM.NONE,
queue_payload_type =>'sys.aq$_jms_text_message',
comment => 'Creating queue table');
dbms_aqadm.create_queue(
queue_name => 'COST_CHANGE_Q',
queue_table => 'change_q_tab',
max_retries => 2,
comment => 'cost change queue');
PROCEDURE enqCostChange(
p_cost_change IN VARCHAR2
,p_priority IN NUMBER          default LOW_PRIORITY
IS
PROC_NM constant VARCHAR2(30) := 'enqCostChange';
v_enqueue_opt DBMS_AQ.enqueue_options_t;
v_message_props DBMS_AQ.message_properties_t;
v_message_handle RAW(16);
-- for JMS
v_cost_change sys.aq$_jms_text_message;
v_agent     sys.aq$_agent := sys.aq$_agent(' ', null, 0);
BEGIN
-- Construct the message for ENQ operation.
--JMS Construction
v_cost_change := sys.aq$_jms_text_message.construct;
v_cost_change.set_replyto(v_agent);
v_cost_change.set_type('mcd://xmlns');
v_cost_change.set_text(p_cost_change);
-- Set proper options and properties
v_enqueue_opt.visibility := DBMS_AQ.ON_COMMIT;
v_message_props.PRIORITY := p_priority ;
DBMS_AQ.enqueue (

END enqCostChange;
