One advantage of sending the URL via a blob message instead of just custom encoding it into a text message is that you don't have to write the custom encoding and decoding code.
Java also has an ActiveMQBlobMessage class ( http://activemq.apache.org/maven/5.13.3/apidocs/org/apache/activemq/command/ActiveMQBlobMessage.html), so you would be able to send one in Java and receive it in C++ or vice versa. But if you used features in one language that were not implemented in the other, then obviously you may not get full compatibility.

If so that ,why I use blobmessage in C++ ,I can use textmessage instead of blobmessage,send and receive URL through by textmessae? my c++ code as follow: commands::ActiveMQBlobMessage* message = new commands::ActiveMQBlobMessage(); message->setStringProperty( "FILE.NAME", "www.jpg" ); message->setRemoteBlobUrl("c:\\www.jpg") producer->send( message ); but my java code can not receive the blobmessage StringProperty "FILE.NAME". public void onMessage(Message message) { if (message instanceof BlobMessage) { BlobMessage blobMessage = (BlobMessage) message; String fileName = blobMessage.getStringProperty("FILE.NAME");} If it is textmessage,my java code can read the StringProperty "FILE.NAME". Does c++ send blobmessage which can only receive by C++ and can not receive by java? -- View this message in context: http://activemq.2283324.n4. nabble.com/BlobMessage-in-ActiveMQ-CPP-by-now-2017-tp4726457p4726533.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
