qpid-send and --properties possible bug/compatibility problem?
Hi,
property passed with message like that:
qpid-send -b ${BROKER} -a exchange/cal --durable yes --content-string "content" --property MyProp=MyValue
will throw MessageFormatException in getStringProperty() in Java JMS client. The class of value is array of bytes instead of String.
javax.jms.MessageFormatException: getString("WoodFileName") failed as value of type class [B is an array.
at org.apache.qpid.client.message.AMQMessageDelegate_0_10.getStringProperty(AMQMessageDelegate_0_10.java:753)
at org.apache.qpid.client.message.AbstractJMSMessage.getStringProperty(AbstractJMSMessage.java:225)
at com.wood.engine.messages.InboundMessageEngine$MtiMessageListener.onMessage(InboundMessageEngine.java:900)
at com.wood.util.jms.MessageListenerBatchAck.runImpl(MessageListenerBatchAck.java:112)
at com.wood.util.jms.MessageListenerBatchAck.run(MessageListenerBatchAck.java:85)
at java.lang.Thread.run(Thread.java:745)
qpid-send as of QPID 0.18, C++ broker 0.18, Java JMS client 0.18. It seems the problem is in qpid-send because message properties passed from .NET are read as Strings in Java.
Kind regards, Jan

I think the JMS client is behaving reasonably, in that a value
explicitly identified as 'binary' is best represented in java as a byte[].

Do you think this might be handled better in the JMS client too. I don't
think that JMS specifies what to do in this case so just coercing the
byte array to a string might also make sense?

Thank you Gordon, I explicitly set the encoding on property variant in qpid-send.cpp and it worked for me too.

That's an issue with qpid-send, which doesn't set the string properties
to be utf8 encoded, meaning they get transferred as binary which is then
converted to a byte[] in Java.
I'll check in a fix for that shortly
(https://issues.apache.org/jira/browse/QPID-5814).
Note you can avoid the issue by explicitly setting the encoding of the
property sent in c++ to "utf8" in the application. (See for example the
fix to drain that was committed already:
http://svn.apache.org/viewvc/qpid/trunk/qpid/cpp/examples/messaging/spout.cpp?r1=1513536&r2=1516917&pathrev=1601779)
