Dear users,
I have an ActiveMQ broker that contains a topic in it. I have pre-configured
the topic as a start up destination. I have written a producer and a
consumer. The following is what I do:
(1) Start ActiveMQ broker
(2) Start my producer. As soon as I do this, my producer starts publishing
Hallo ActiveMQ Users,

Thanks for the reply. I can see from the ActiveMQ documentation that there
are many possible ways to do Authentication and Authorization. For example.,
to Authenticate, I can use SSL, JAAS Certificate Authentication, JAAS LDAP
Authentication, JAAS Username, Password Authentication.

Guys,
I"m looking for suggestions if I should consider using LDAP for
authorization? Does the authorization happen only once when my clients set
up their connection? or does it happen for every messages published or
consumed by the clients?

Ok. I got past that error of the login.config file not being found.
Another issue that popped out is as below:

I found the following information from Fuse source documentation.

get the Subject DN. I copy this Subject DN and use it in my users.propertie
When I still need the key store and trust store, why will I use this JAAS
plug in for authentication? I can very well use SSL Authentication in the
form of certificates stored in the trust store of the broker and my client.
I understand that I can plug in authorization rules, but for that I could
Ok. I got this working. I had to create a new trust store for the broker,
import my client certificate in it and copy the created broker trust store
to ACTIVEMQ_HOME/conf directory. I had to modify my SSL context in the
activemq.xml to specify my trust store and the trust store password.

Guys,
I'm trying to get my ActiveMQ server run using a SSL connection. I have done

I had a look at the ActiveMQ in Action examples and that uses the
activemq-security.xml to start the ActiveMQ. But I guess that should not
matter.
I will check for those braces and see if that works!

I would try increasing the maxReconnectAttempts to a bigger value. Is there a
rule of thumb as to how big this should be? Is there an indefinite try? what
happens if I specify -1? Will it try indefinitely until it gets a
connection? I would love to have that!

It's not with two hosts, but with two hosts and a shared database, I lock the
second to a waiting state. I got the point. So my earlier understanding was
correct that with a Master / Slave and a shared database lock, the slave
will not start it's transport connectors and will wait for the lock.

When I configure the networkConnector in the activemq.xml file, I'm doing a
network of brokers. Did I get it correctly?
When my clients use a failover protocol, it is a failover scenario. Is this
correct as well?
In my case, I have both. Something similar to this.

I'm happy to see some help at last.
Here is how the fail-over url looks like from my clients (both producer and
consumer)

But isn't configuring the networkConnectors with a static discovery in the
activemq.xml configuration file is a network of brokers?

I"m trying to understand the concept behind the network of brokers in
ActiveMQ. What I understand from the documentation is that by having a
network or broker we can get load balancing. I would assume that load
balancing would mean that the messages are sent to either one of the brokers

What is more troubling me is that the messages sent by the Producer to a
Topic is lost when the Master goes down. When I restart my consumer, all
those messages that the Producer had sent to the Topic was lost. How do I
handle this? Where is the high availability in picture in this AMQ
Clustering?
Can you show me some pointers on how to use a durable consumer?

That seems like a restricted solution that the Consumer should be a servlet.
May I know why?
What I have is a standalone Consumer (for testing purposes). Not sure how
the Production systems are, but the standalone Consumer dies as soon as the

Did you find a solution to this? I have more or less the same issue. My
