JMS/AQ inside Oracle 9i is slow?

Question

Hi.
I have a trigger inside the Oracle 9i DB that calls a java stored procedure. The procedure sets up a JMS connection and publishes a message to all the subscribers but this takes 1-3 seconds. I need a close to real-time solution. Is there any way of speeding this up? Here is my code:
Topic topic;
TopicSession tsess = null;
TopicConnectionFactory tcfact =null;
TopicConnection tconn =null;
TopicPublisher publisher = null;
TextMessage txtmsg, dtxtmsg;
try
OracleDriver ora = new OracleDriver();
tconn = AQjmsTopicConnectionFactory.createTopicConnection(ora.defaultConnection());
/* Create a Topic Session */
tsess = tconn.createTopicSession(true, Session.AUTO_ACKNOWLEDGE);
tconn.start() ;
topic = ((AQjmsSession)tsess).getTopic("ts","tstopic") ;
publisher = tsess.createPublisher(topic);
txtmsg = tsess.createTextMessage() ;
txtmsg.setText("New alarm") ;
txtmsg.setStringProperty("alarmID", "id") ;
txtmsg.setStringProperty("Date", "None") ;
publisher.publish(topic, txtmsg) ;
tsess.commit() ;
return "success";
} catch (Exception e) {
System.out.println("Error in performJmsOperations: " + e) ;
return e.getMessage();
finally
try
tconn.close();
catch(Exception e)
e.printStackTrace();
}
