Oracle Streams and JMS: A dead combination?
Oracle Streams is supposedly a JMS implementation. After a month of waiting on Oracle support as to why some of the basic examples did not work I got: Note:154777.1 Subject: Unable to Create Receiver on a Raw Queue Type: PROBLEM Status: PUBLISHED Content Type: TEXT/X-HTML Creation Date: 20-JUL-2001 Last Revision Date: 13-AUG-2001 * fact: Oracle Server - Enterprise Edition 8.1.7 * fact: Advanced Queuing (QUEUE) * symptom: Runtime error using the Java Messaging Service (JMS) * symptom: java.lang.NullPointerException * symptom: oracle.jms.AQjmsSession.createReceiver(javax.jms.Queue) * cause: Access to queues with a RAW payload via the JMS API is not supported. fix: 1. Use the native Java API - oracle.AQ.* to access the RAW queue. 2. Use one of the predefined payload types for JMS. In this case SYS.AQ$ _JMS_TEXT_MESSAGE was used. For more information on JMS and the Java AQ API, refer to : Oracle8i Application Developer's Guide - Advanced Queuing. The native API is not deprecated. So all of this adds up to Oracle Streams and JMS being a dead combination on Oracle.Posted by gluck at May 20, 2005 07:07 AM
