Can we write and read the message using RFHUTILC into ActiveMQ?
I know RFHUTILC is used for writing and reading messages into IBM MQ but my requirement is to pull/Read a message from Apache ActiveMQ.
RFHUTILC won't work, as it only talks IBM MQ's protocol, which is non-standard and specific to IBM MQ. ActiveMQ supports a number of standard and open source protocols, as #Justin Bertram mentioned.
RFHUTIL is IBM MQ only. I made a smilar tool called A that has been around sometime for ActiveMQ (generic JMS with OpenWire/ActiveMQ, HornetQ and AMQP protocols bundled) that you can use instead. It's command line though, no GUI. Free/open source.

There are of course other similar utilities with GUI, such as Hawt.IO among others. Some are a bit outdated though (Hermes JMS).

I am getting my data through ActiveMQ which I want to process in real time with Apache Flink DataStreams. There is support for many messaging services like RabbitMQ and Kafka but I can't see any support for ActiveMQ. How can I use it?
Since there is not support for ActiveMQ, I would recommend implement a custom source.
You basically have to implement the SourceFunction interface.
If you want to have exactly-once semantics, you can base your implementation on the MultipleIdsMessageAcknowledgingSourceBase class.
I would recommend you to start with implementing a SourceFunction
Found a JMS connector for Flink:

The only answer that I can find seems to say that the datapower appliance only support Websphere MQ, and it doesn't understand ActiveMQ brokers.
And, the documentation for Front Side Handler mentioned Queue managers, which ActiveMQ does not have.
Is there another way in datapower to fetch/poll messages from an activeMQ?
WDP does not support all possible brokers but just a few of them (Tibco, IBM etc). If you configure AMQ to provide a REST interface you can consume messages from it using plain HTTP instead of messaging.
REST/HTTP access to ActiveMQ won't be nearly as good as traditional OpenWire/AMQP connections. It will lack support for transactions and other things, but you can at least read messages.
I do not suggest using an ActiveMQ as messaging backbone for DataPower - go for IBM WebSphere MQ instead as they are nicely integrated. If you need to occasionally pull a message or two from an ActiveMQ broker - go for the above setup.
RabbitMQ supports multiple protocols, AMQP, MQTT, STOMP, ....
When using PHP for example, it's easier to publish using the STOMP library since the PHP AMQP libraries requires compiled C code and is somewhat of a mission to setup if you don't have to.
On the JAVA side, apache camel with AMQP on spring is pretty straight forward.
Is it possible to setup a queue, publish to it via STOMP and then consume via AMQP and then again publish via AMQP and consume via STOMP if the message broker is RabbitMQ?
Yes, this should work, given that you have installed RabbitMQ's STOMP plugin on your RabbitMQ node(s).
The protocol only defines the communication between client and server and has no impact on a message itself.
You should note that using protocols other than AMQP will most likely come along with limitations and/or worse performance.
There also exist native PHP libraries for RabbitMQ that don't require compiling C code. Unfortunately, I cannot tell you which one is the best, because I am a Java guy ;-).
I have worked on IBM MQ and this is the first project where I am to work on ActiveMQ. After reading basic tutorial I found that both are similar. So I started creating small applications to listen to some queues.
Working with IBM MQ, I used to use RFHUtil tool to browse/send messages to queue which provided features to set message headers as well.
In activeMQ I am sending messages from localhost admin console. I do not find options to set message header from here. For example if I want to set source system in the message header. Is there any way/tool to get this feature on activeMQ?
I like hermes jms
Be sure to pick the Head version if you want support for headers. Its pretty similar to RFHUtil but allows "all" JMS providers.

I also made a command line tool for the same task which is handy, called A.
Currently I am researching open source message broker technology that can provide support for ebXML I would like to use Apache ActiveMQ.
I will be looking at supporting Oasis ebXML AS4 specification.
My question is, does Apache ActiveMQ as a JMS broker offer adequate support for ebXML, in particular ebXML 3 AS4?
Are there any alternative open source message broker technology more suited to ebXML?
Lastly is there a .NET interface library to support ebXML support via ActiveMQ?
Thanks in advance,
Marcus
What do you mean by "support"?
Apache ActiveMQ is a messaging component. It does not really care about the content in the messages, but should merly be seen as a transport channel.
Apache Camel comes bundle with ActiveMQ do support XML (parsing, transforming), but not ebXML explicitly.
Typically, explicit support for these industry standard EDI formats are rarely implemented in open source middleware. There might be some old java library open source out there ( ebXml OpenSource java implementation ), but nothing very active, unfortunately.
