Newbie: standalone java AQ client

Question

Hello.
I need to write content from the java program to the Oracle 10g queue.
I can get acquire the datasource in multiple ways (via DriverManager, Spring's dataSource support classes or from running local OCJ4 via jndi) and than do the following :
QueueConnectionFactory qc_fact = AQjmsFactory.getQueueConnectionFactory(dataSource);
QueueConnection qc_conn = qc_fact.createQueueConnection(USER, PASS);
QueueSession q_session = qc_conn.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
AQjmsSession jms_sess = AQjmsSession.class.cast(q_session);
Queue queue = jms_sess.getQueue(Q_USER, Q_NAME);
AQjmsProducer q_sender = (AQjmsProducer) jms_sess.createProducer(queue);
TextMessage msg = jms_sess.createTextMessage("Hello queue!");
q_sender.send(msg, DeliveryMode.PERSISTENT, 1, 600000);Also i''ve enable tracing with AQjmsOracleDebug class.
The output is always the same (this was when using oci4j jndi datatsource lookup):

Is there any way to enqueue a message from the simple standlone java app?

Sample Code
Sample Code Output
Applies to:
Oracle Server - Enterprise Edition - Version: 9.2.0.4.0
Information in this document applies to any platform.
DATABASE 9.2.0.7
JDEVELOPER 10.1.2.1
Purpose
The sample code will enqueue and dequeue a message.
Software Requirements/Prerequisites
SQLPLUS that comes with Oracle Database 9.2.0.7
JDeveloper 10.1.2.1
JDBC Driver that comes with Oracle 10.1.2.1 (10.1.0.4.2)
JDK 1.4.2.06
AQ Api that comes with JDeveloper 10.1.2.1 (jta.jar , aqapi13.jar , jms.jar)
Configuring the Sample Code
You need to use Sqlplus to create the queue table, queue and start the queue.
You need Jdeveloper to create the JMS client that will enqueue and dequeue the message.
Steps will follow
Running the Sample Code
I- In sqlplus:
1. Run the following to grant privileges to user:
connect sys/welcome@orcl92 as sysdba
grant aq_administrator_role to scott;
grant execute on dbms_aqadm to scott;
grant execute on dbms_aq to scott;
grant execute on dbms_aqin to scott;
grant execute on dbms_aqjms to scott;
connect scott/tiger
2. Create the Queue Table and the Queue:
BEGIN
sys.dbms_aqadm.create_queue_table (
queue_table => 'POA_QUEUE_TABLE'
, queue_payload_type => 'SYS.AQ$_JMS_TEXT_MESSAGE'
, sort_list => 'ENQ_TIME'
, comment => ''
, multiple_consumers => TRUE
, message_grouping => DBMS_AQADM.NONE
, compatible => '8.1'
, primary_instance => '0'
, secondary_instance => '0');
COMMIT;
END;
BEGIN
sys.dbms_aqadm.create_queue(
queue_name => 'POA_QUEUE'
, queue_table => 'POA_QUEUE_TABLE'
, queue_type => sys.dbms_aqadm.NORMAL_QUEUE
, max_retries => '5'
, retry_delay => '0'
, retention_time => '0'
, comment => '');
END;
BEGIN
sys.dbms_aqadm.start_queue(
queue_name => 'POA_QUEUE'
, enqueue => TRUE
, dequeue => TRUE);
END;
begin DBMS_AQADM.ADD_SUBSCRIBER
('POA_QUEUE'
, SYS.AQ$_AGENT('POA_SUBSCRIPTION'
, NULL
, NULL));
end;

This script is provided for educational purposes only and not supported by Oracle Support Services. It has been tested internally, however, and works as documented. We do not guarantee that it will work for you, so be sure to test it in your environment before relying on it.
Proofread this sample code before using it! Due to the differences in the way text editors, e-mail packages and operating systems handle text formatting (spaces, tabs and carriage returns), this sample code may not be in an executable state when you first receive it. Check over the sample code to ensure that errors of this type are corrected.
Sample Code
II- In JDeveloper 10.1.2.1
1. Create a workspace with a project.
2. Create DBSession.java which will have the following code:
package mypackage1;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import javax.jms.JMSException;
import javax.jms.TextMessage;
import javax.jms.Topic;
import javax.jms.TopicConnection;
import javax.jms.TopicPublisher;
import javax.jms.TopicSession;
import javax.jms.TopicSubscriber;
import oracle.AQ.AQDequeueOption;
import oracle.AQ.AQDriverManager;
import oracle.AQ.AQEnqueueOption;
import oracle.AQ.AQException;
import oracle.AQ.AQMessage;
import oracle.AQ.AQObjectPayload;
import oracle.AQ.AQOracleQueue;
import oracle.AQ.AQOracleSession;
import oracle.AQ.AQQueue;
import oracle.AQ.AQRawPayload;
import oracle.AQ.AQSession;
import oracle.jms.AQjmsSession;
import oracle.jms.AQjmsTopicConnectionFactory;
public class DBSession {
public static Connection db_conn;
public static AQSession createSession(String args[]) {
AQSession aq_sess = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
// replace with specific host:port:databasename
db_conn = DriverManager.getConnection("jdbc:oracle:thin:@dbhost:1521:orcl92","scott","tiger");
System.out.println("JDBC Connection opened ");
db_conn.setAutoCommit(false);
Class.forName("oracle.AQ.AQOracleDriver");
// Create AQ Session.
aq_sess = AQDriverManager.createAQSession(db_conn);
System.out.println("Successfully created AQSession ");
} catch (Exception ex) {
System.out.println("Exception: " + ex);
ex.printStackTrace();
return aq_sess;
public static void AQObjectPayloadTest(AQSession aq_sess)
throws AQException, SQLException, ClassNotFoundException, JMSException
//Used for standard AQ
AQQueue queue = null;
AQMessage message = null;
AQRawPayload payload = null;
AQEnqueueOption eq_option = null;
AQDequeueOption dq_option = null;
//Used for subscription and topic based queues.
Topic inqueueTopic, outqueueTopic;
TopicConnection topicConnection;
TopicSession session;
TextMessage out = null;
TopicSubscriber subscriber;
TextMessage textMessage;
TopicPublisher publisher;
// Configure for specific host, Database, port, etc..
String hostname = "DBhostname";
String database = "orcl92";
String user = "scott";
String password = "tiger";
String schema = "scott";
String inqueue = "POA_QUEUE";
String outqueue = "POA_QUEUE";
String subscription = "POA_SUBSCRIPTION";
String port = "1521";
// JMS Dequeue implementation.
// Create a topic session and connection..
topicConnection = AQjmsTopicConnectionFactory.createTopicConnection(db_conn);
session = topicConnection.createTopicSession(true, 0);
topicConnection.start();
inqueueTopic = ((AQjmsSession)session).getTopic(schema, inqueue);
outqueueTopic = ((AQjmsSession)session).getTopic(schema, outqueue);
// Enqueue a test message
textMessage = session.createTextMessage();
textMessage.setJMSCorrelationID("POA_QUEUE");
textMessage.setText("Test Message!!!");
publisher = session.createPublisher(outqueueTopic);
publisher.publish(textMessage);
publisher.close();
session.commit();
// Dequeue the same message
inqueueTopic = ((AQjmsSession)session).getTopic(schema, inqueue);
outqueueTopic = ((AQjmsSession)session).getTopic(schema, outqueue);
subscriber = session.createDurableSubscriber(inqueueTopic,subscription);
out = (TextMessage)subscriber.receive(0);
System.out.println("Message retrieved: " + out.getText());
db_conn.commit();
You need to modify the hostname, port, sid according to your environment.
3. Create AQTest.java:
package mypackage1;
import java.sql.SQLException;
import javax.jms.JMSException;
import oracle.AQ.AQException;
import oracle.AQ.AQSession;
public class AQTest {
public static void main(String[] args)
AQTest test = new AQTest();
test.start();
private void start() {
//create session
AQSession session = DBSession.createSession(null);
//create queue
try {
DBSession.AQObjectPayloadTest(session);
} catch (AQException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
catch (JMSException jmse) {
jmse.printStackTrace(); }
4. Compile and run AQTest.java. You will get the following output:
Sample Code Output
JDBC Connection opened
Successfully created AQSession
Message retrieved: Test Message!!!
Process exited with exit code 0.
