Hi,
I'm running Artemis 1.3.0 embedded inside a spring app running in Tomcat.
I have a remote message producer (NumberGuessMain.java) that uses the Apache
Qpid Proton library to push messages onto an Artemis queue with the URL:
amqp://localhost:5672/native-2-java
The messages created by the producer are JSON strings.
I have a single threaded, singleton consumer that uses the native Artemis API
(NativeProcessMsgReader.java) running inside the same web app as Artemis,
reading from the queue:
native-2-java
While there are no messages to read, the consumer happily loops through the
while loop in the "run" method.
As soon as the consumer tries to read the body of the first message, it hangs
on the line:
String receivedMsg = msgReceived.getBodyBuffer().readString();
The last lines in the log file are:
2016-09-01T22:27:26,270 15137 [Thread-6] DEBUG
c.a.t.r.p.d.a.c.NativeProcessMsgReader - run - no message during last read
period
2016-09-01T22:27:26,270 15137 [Thread-6] DEBUG

2016-09-01T22:27:26,772 15639 [Thread-6] DEBUG

2016-09-01T22:27:26,912 15779 [Thread-6] DEBUG

2016-09-01T22:27:26,912 15779 [Thread-6] DEBUG
c.a.t.r.p.d.a.c.NativeProcessMsgReader - run - non-null message, body length:
307
To me this looks like the message has reached Artemis and is made available to
the consumer but something goes wrong when the consumer tries to access the
body of the message.
I'm new to Artemis and AMQP so it's quite possible I'm doing something stupid...
Is the basic assumption that it's ok to send a message using AMQP and receive
it using Artemis core API valid?
Is there something obvious in the code that is causing this problem?
Any pointers gratefully received.
Cheers, Andy
