[jboss-user] [Messaging, JMS & JBossMQ] - IOException: Incorrect number of bytes read.

Using JBoss 4.0.5-GA with JDK 1.5.0_06 and getting this issue with JBossMQ when the MDB is trying to acquire our business data object from the body of an ObjectMessage | javax.jms.MessageFormatException: IOException: Incorrect number of bytes read. | at org.jboss.mq.SpyObjectMessage.getObject(SpyObjectMessage.java:158) | I did some groundwork looking for a solution and I can't seem to find any posting regarding this issue. I also included the method that i believe to be the culprit of this issue. On setObject(Serializable) the flush() method is not called prior to extracting byte array from ByteArrayOutputStream. So I would suspect that if the ObjectOutputStream did not by chance automatically flush to the memory stream it would make sense why some bytes appear to be lost. | public void setObject(Serializable object) throws JMSException | { | if (header.msgReadOnly) | { | throw new MessageNotWriteableException("setObject"); | } | if (object == null) | { | objectBytes = null; | return; | } | try | { | if (object instanceof byte[]) | { | //cheat for byte arrays | isByteArray = true; | objectBytes = new byte[((byte[]) object).length]; | System.arraycopy(object, 0, objectBytes, 0, objectBytes.length); | } | else | { | isByteArray = false; | ByteArrayOutputStream byteArray = new ByteArrayOutputStream(); | ObjectOutputStream objectOut = new ObjectOutputStream(byteArray); | objectOut.writeObject(object); | objectBytes = byteArray.toByteArray(); | objectOut.close(); | } | } | catch (IOException e) | { | throw new MessageFormatException("Object cannot be serialized"); | } | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4019958#...
