I am looking for creating a websocket client for using rabbit mq stomp over websocker using java.
I using jetty client and i am getting org.eclipse.jetty.websocket.api.UpgradeException: Didn't switch protocols
Looks like the issue is with the Rabbit MQ version. After I've upgraded from Ubuntu default one to the newest Rabbit MQ version from https://www.rabbitmq.com/install-debian.html it worked for me.
Look at this example: stomp-websockets-java-client
Please read first:
http://jmesnil.net/stomp-websocket/doc/
http://www.rabbitmq.com/blog/2012/05/14/introducing-rabbitmq-web-stomp/
not perfect, it's far from the worst way do messaging in the browser: exposing STOMP through Websockets.

I am trying to find a workable recipe to connect to ActiveMQ Artemis from Java 1.6.
Any ideas? Any way to leverage another client and protocol to connect to Artemis?
You could possibly use a legacy HornetQ client that supported JDK 1.6. Artemis has worked to maintain backwards compatibility with HornetQ so it should work OK.
Also, you could use a STOMP client that supports JDK 1.6. STOMP is a very simple protocol so even if you couldn't find one with JDK 1.6 support you could write your own if necessary.
Has anyone succeeded in creating a bridge between IBM MQSeries (MQS) and ActiveMQ Artemis 7.x (AMQ 7) so that the later can send messages to and receive from the first? Currently I have no problem bridging between MQS 7.5 and AMQ 6.3 by deploying a camel route and MQS libraries on the broker itself. However, the same way doesn't work anymore as each route deployment requires a broker reconfiguration and restart.
Thanks in advance for any feedback.
A few examples ship with ActiveMQ Artemis which might be helpful:
The "inter-broker-bridge" example in the examples/features/sub-modules/ directory. This example demonstrates how to deploy an instance of org.apache.activemq.artemis.jms.bridge.impl.JMSBridgeImpl to the broker using Spring in a web application.
The "camel" example in the examples/features/standard/ directory. This example demonstrates how to deploy a Camel route to the broker using Spring in a web application.
I can't speak to whether or not either of these can be updated at runtime as I've not actually attempted that. Both of these options should be able to move messages in either direction (i.e. from Artemis to MQS or from MQS to Artemis).
Another option would simply be to run Camel standalone and deploy your routes there. This would give you more flexibility as it would allow you to specifically choose the hardware where the routes run as well as how many resources the Camel JVM consumes. Running Camel routes directly on the broker, while convenient, isn't a great fit because the broker is a broker and not an application server.
To be clear, ActiveMQ Artemis and IBM MQSeries are not directly compatible with each other and are not expected to be. This true for most (if not all) JMS broker implementations. The role of components like the ActiveMQ Artemis JMS bridge and integration platforms like Camel are to solve the compatibility problem by using a common API to speak to both brokers - JMS in this case. Any broker which implements JMS can be integrated using these methods.
Does Apache Active MQ provide Server-To-Server-Connection as IBM Websphere MQ does?
Background:
We currently have Websphere MQ 7.0.1 (CUST) installed to communicate with another remote Websphere MQ Server (GOV), which is not under our control.
The MQs hold a Server-To-Server-Connection via VPN-tunnel. We would like to replace our Websphere MQ with Apache ActiveMQ.
We have one QM-Manager with 4 queues and 3 channels.
Queues:
OUT (type remote): for sending messages to GOV
QOUT (local type transmission) that is used for OUT
IMP (local): used for receiving from GOV
DLQ: (local): dead letter queue
Channels:
conch: server connection
CUST_GOV: sender
GOV_CUST: receiver
I read a lot about bridging ActiveMQ to Websphere MQ (Client API, Resource Adapter, OSGi) with Camel.
Looks pretty easy with a Camel route, but this is at least a Client-Server setup.
E. G. https://www.shaishavparekh.com/2016/01/wmq-to-amq-bridge/
I need something that hides away the IBM proprietary channel stuff.
Now I found this entry: https://serverfault.com/questions/366743/apache-activemq-server-to-server-connection
As this is from 2012 I would like to ask, if anyone successful switched from Websphere MQ to ActiveMQ resp. is it still true that I can only use Client-Server?
ActiveMQ does not support a server-to-server connection to WebsphereMQ. As you mentioned, Camel would probably be the simplest way to get a connection between the two brokers.
To be clear, even if ActiveMQ did implement a bridge with WebsphereMQ it would almost certainly use the WebsphereMQ client so would fundamentally still be a client-server implementation. It's not really clear from your question why you want to avoid this.
Looking java code to connect with ArtemisActiveMQ. Earlier using HornetQ for messaging but now need to migrate on ArtemisActiveMQ.
Apache ActiveMQ Artemis ships with numerous examples. Take a look at super-simple "queue" example for a demonstration of how to use the JMS API to connect.
I have a jms server running on weblogic and I need another application running on another server (weblogic as well) to listen to JMS topics sent by the JMS server mentioned before. The fact is that I don't know how to do that. I mean, what do I need on the consumer application side? Thansk in advance.
I know it´s a little old, but could help other people trying to achieve the same.
First you need to enable Cross-Domain Security on both domains envolved on your JMS communication. Please see specific documentation here: https://docs.oracle.com/middleware/1221/wls/SECMG/domain.htm#SECMG402
For reading a message from a JMS resource, there are a ton of examples you can search online, but basically you should rely on Weblogic´s t3 protocol. Here is a relativelly recent example using Spring Boot: Connect to remote jms queue with Spring Boot
