Is the Blob successfuly uploaded? Can you see it in the jetty file system?
No, the blob isn't uploaded at all. Moreover, I added the code listed below:
===============================================================================
private BlobTransferPolicy getTransferPolicy() {
BlobTransferPolicy policy = new BlobTransferPolicy();
policy.setUploadStrategy(new DefaultBlobUploadStrategy(policy) {
@Override
public void deleteFile(ActiveMQBlobMessage message)
throws IOException, JMSException {
System.err.println("Removing file");
super.deleteFile(message);
}
@Override
public URL uploadFile(ActiveMQBlobMessage message, File file)
throws JMSException, IOException {
System.err.println("Uploading file");
return super.uploadFile(message, file);
}
@Override
public URL uploadStream(ActiveMQBlobMessage arg0, InputStream arg1)
throws JMSException, IOException {
System.err.println("Uploading stream");
return super.uploadStream(arg0, arg1);
}
});
return policy;
}
....
public void run() {
final ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory(
"tcp://localhost:1235");
final BlobTransferPolicy policy = getTransferPolicy();
factory.setBlobTransferPolicy(policy);
try {
final ActiveMQConnection connection = (ActiveMQConnection) factory
.createConnection();
System.out.println("Using upload url = "
+ policy.getDefaultUploadUrl());
connection.setBlobTransferPolicy(policy);
connection.start();
final ActiveMQSession session = (ActiveMQSession) connection
.createSession(false, Session.CLIENT_ACKNOWLEDGE);
session.setBlobTransferPolicy(policy);
final Destination destination = session
.createQueue(ImageProcessorInterface.srcImgQueueName);
final Destination tempDestination = session.createTemporaryQueue();
final MessageProducer producer = session
.createProducer(destination);
final MessageConsumer responseConsumer = session
.createConsumer(tempDestination);
responseConsumer.setMessageListener(new MessageListener() {
producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
for (int i = 0; i < MESSAGES_NUMBER; i++) {
InputStream data = ImageProducer.class
.getResourceAsStream("/sample_image.jpg");
System.out.println("Data stream is " + data);
final BlobMessage message = session.createBlobMessage(data);
message.setJMSReplyTo(tempDestination);
message.setJMSCorrelationID(generateMsgId());
producer.send(message);
Thread.sleep(SLEEP_TIME);
}
} catch (final Exception e) {
throw new RuntimeException(e);
}
System.out.println("Done");
}
===============================================================================
to inject a custom BlobTransferPolicy into ActiveMQConnectionFactory,
ActiveMQConnection and ActiveMQSession instances - but as far as I can see,
there's noting about an attempt to upload the file in logs. At this point I'm
stuck :)
Hello,
First try this. Set CopyMessageOnSend to false on your connection. See
http://www.nabble.com/A-problem-with-blobmessage-on-activemq-5.0-td15523989.html#a17364301
If this is true (default) the Upload does not work.
If that will not help please provied the whole code including the broker
an jetty start. I think you will start the broker and jetty programmaticaly.
regards
Marco
