Hello, I am new to activemq and activemq-cpp. My goal is to setup queues for communication between a web browser (over websocket/STOMP) and a C++ program. Since there is some additional business logic, I've setup a springboot application with embedded ActiveMQ server and configured the Websocker STOMP support to relay/listen to the embedded server. The relevant spring configuration code on the java side looks like (1) and (2) below.
On the C++ side I cloned the repo https://gitbox.apache.org/repos/asf/activemq-cpp.git and compiled it on macOS. Then I modified the example code in src/examples/Main.cpp to connect the HelloWorldConsumer and HelloWorldProducer to two different queues.The relevant places in the main() function look like (3) below, the modifications in the classes are not shown, but are simply a new member in each and adapted session->createQueue() calls in run(). The queue to listen on is /myQueue/ below and the queue to put messages in is /yourQueue/ below. And there is some Test code in Java that creates a websocket client, connects it to the springboot websocket port, registers a listener to the "/queue/browser" and sends a message to "/queue/plugin". This is shown in (4) below. Now here is the problem: The reception of messages from the C++ side to the "browser" (my websocket listener) works fine, the textmessage is transmitted and can correctly be parsed and displayed. The message from the "browser" to the C++ side is transmitted and arrives there, BUT is corrupted (i.e. it is NULL). Here is the output that I get from the example: /Message #1 Received/ is the one from the "browser" (my test code), and the "NOT A TEXTMESSAGE" string is displayed because it is NULL (a NULL check in the HelloWorldConsumer::onMessage() method). The text message is apparently not correctly parsed on the C++ side. Is there something missing some further configuration to be done in my code? Or is it a bug/missing feature? Can I do something to make it work anyway ? Thanks in advance (1) Jms configuration (2) Websocket configuration (3) Relevant places in edited src/examples/Main.cpp of the activemq-cpp code (4) Java Test code to put a message in the "plugin" queue that should be consumed on the C++ side. -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
