Java 通过在AQjmsProducer.jdbcEnqueue抛出的JMS:NPE使用Oracle高级队列

我想通过JMS使用Oracle高级队列

我已经通过plsql创建了如下队列表和队列：

BEGIN
DBMS_AQADM.CREATE_QUEUE_TABLE(
queue_table            => 'QT3',
queue_payload_type     => 'RAW');
END;
/

BEGIN
DBMS_AQADM.CREATE_QUEUE( 
queue_name          => 'Q3', 
queue_table         => 'QT3'); 
END;
/

    System.setProperty("oracle.jms.traceLevel", "6");

    ConnectionFactory connectionFactory = AQjmsFactory.getConnectionFactory("x.x.x.x", "xxx", 1521, "thin");
    Connection connection = connectionFactory.createConnection("xxx", "xxx");
    connection.start();

    Session session = connection.createSession(true, 0);
    Queue queue = session.createQueue("Q3");
    MessageProducer producer = session.createProducer(queue);
    TextMessage message = session.createTextMessage("valami");
    message.setJMSType("text");
    producer.send(message);
    session.commit();

然后我尝试发送这样的消息：

BEGIN
DBMS_AQADM.CREATE_QUEUE_TABLE(
queue_table            => 'QT3',
queue_payload_type     => 'RAW');
END;
/

BEGIN
DBMS_AQADM.CREATE_QUEUE( 
queue_name          => 'Q3', 
queue_table         => 'QT3'); 
END;
/

    System.setProperty("oracle.jms.traceLevel", "6");

    ConnectionFactory connectionFactory = AQjmsFactory.getConnectionFactory("x.x.x.x", "xxx", 1521, "thin");
    Connection connection = connectionFactory.createConnection("xxx", "xxx");
    connection.start();

    Session session = connection.createSession(true, 0);
    Queue queue = session.createQueue("Q3");
    MessageProducer producer = session.createProducer(queue);
    TextMessage message = session.createTextMessage("valami");
    message.setJMSType("text");
    producer.send(message);
    session.commit();

上面的代码找到了队列（如果我将Q3替换为其他内容，那么它会显示queue not found，所以我想基本连接设置是可以的），但我在producer.send中遇到了NPE异常。我设置了aqapi跟踪，得到了以下输出：

main [Fri Jun 20 14:22:51 CEST 2014] AQjmsProducer.send-1:  entry
main [Fri Jun 20 14:22:51 CEST 2014] AQjmsProducer.send-main:  entry
main [Fri Jun 20 14:22:51 CEST 2014] AQjmsProducer.send:  queue: RISKOPALL.Q3
main [Fri Jun 20 14:22:51 CEST 2014] AQjmsProducer.send:  dest_queue: RISKOPALL.Q3
main [Fri Jun 20 14:22:51 CEST 2014] AQjmsProducer.jdbcEnqueue:  entry
main [Fri Jun 20 14:22:51 CEST 2014] AQjmsProducer.checkMessageType:  adt type: null
main [Fri Jun 20 14:22:51 CEST 2014] AQjmsProducer.checkMessageType:  message_class: oracle.jms.AQjmsTextMessage
main [Fri Jun 20 14:22:51 CEST 2014] AQjmsProducer.jdbcEnqueue:  exit
Exception in thread "main" java.lang.NullPointerException
    at oracle.jms.AQjmsProducer.checkMessageType(AQjmsProducer.java:2362)
    at oracle.jms.AQjmsProducer.jdbcEnqueue(AQjmsProducer.java:823)
    at oracle.jms.AQjmsProducer.send(AQjmsProducer.java:747)
    at oracle.jms.AQjmsProducer.send(AQjmsProducer.java:517)
    at aqjms.AqJmsTest.main(AqJmsTest.java:55)

我反编译了aqapi.jar，发现NPE被抛出，因为AQjmsProducer.checkMessageType的“adtType”参数为null

此ADT类型是什么？如何正确设置

多谢各位

设置队列的有效负载类型解决了问题：

BEGIN
DBMS_AQADM.CREATE_QUEUE_TABLE(
queue_table            => 'QT3',
queue_payload_type     => 'SYS.AQ$_JMS_TEXT_MESSAGE',
compatible => '8.1.0');
END;
