dataDirectory attrib isn't respected?
my startup xbeans file has an attribute for
dataDirectory on the broker line, but when i start up
activemq it not only makes me the directory i ask for,
but it also makes a "activemq-data" directory where
ever i started up activemq. this doesn't seem right,
so i attached a debugger to the code src, and it seems
like it's starting two brokers within one vm. the one
that i asked it for and an additional one.
my startup script is quite simple, it's actually
identical to the "multicast-broker1.xml" demo except i
add dataDirectory attribs.
how do i get it to respect my dataDirectory, and
additionally, how do i prevent the startup of this
additional vm://null broker?
thanks
here's my startup script:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:amq="http://activemq.org/config/1.0">
<amq:broker brokerName="a03"
dataDirectory="/tmp/mbus/03/A/journal"
persistent="false" useShutdownHook="false"
useJmx="false">
<amq:transportConnectors>
<amq:transportConnector
uri="tcp://localhost:0"
discoveryUri="multicast://default"/>
</amq:transportConnectors>
<amq:networkConnectors>
<amq:networkConnector
uri="multicast://default"/>
</amq:networkConnectors>
<amq:persistenceAdapter>
<amq:memoryPersistenceAdapter/>
</amq:persistenceAdapter>
</amq:broker>
</beans>

Well, another problem I'm having from a loooong time without solutions.
I've exactly the same problem and let me add to you message that it
happens even if you start embeded brokers.
I´m starting my brokers from a JBoss mbean service using a xbean file
config where I point my data directory to an outside JBoss directory.
Nevertheless, I discovered that, after start JBoss I've a new
activemq-data directory inside jboss/bin directory.
Please, let me know if you found a solution.

Ah right! :)
Yeah - we should add some validation to the code to check for bad URI
syntaxes and update the docs

Great; yeah its a limitation of the URI class we use for URI coding etc
Will add more stuff to the wiki to catch this...

actually, no. i was using 01_A, 02_A, etc.
this doesn't work.
i've changed them to a1, a2, a3 and it works.
i didn't notice anywhere in the docs where you cannot
have a broker named starting w/ a number and/or
containing an underscore.
not sure which was the troublesome spot, but amending
both seems to have rectified the problem.

Are those the exact broker names right?

I don't follow how a vm:// broker can be being started if you don't
mention it in the activemq.xml and there's no other Java code in the
broker being run.
Which platform/JVM etc? Any other hints how to reproduce?

Yes, i'm running the cmd-script w/ just those xml
config files that i sent, and nothing else.
i was using RC2, then i started using snapshot from
incubator-activemq-4.0-SNAPSHOT (dated may 8th)
i've got three copies of what i posted, [1,2,3].xml
inside each one, i've changed the dataDirectory attrib
to the respective number
(/opt/mbus/01, /opt/mbus/02, ...)
and changed the name of the broker (a1,a2,a3)
what you're talking about, though (the early boot)
seems to be occurring, b/c it's (a) not respecting the
dataDirectory attrib, and (b) it seems to be starting
a vm:// broker as well as the tcp one.
thoughts?

You are getting this error when running the activemq command script -
with just those XML configuration files you sent and nothing else?
BTW you are using a recent version right (4.0 or 4.0-RC3)? There was a
bug months ago with the configuration of the transport XML causing an
early boot up of the persistence layer before the persistence layer
was properly configured.

Re: dataDirectory attrib isn't respected?

i have a different config/startup file for each
broker, though.
in my posted startup/config file, i don't explicitly
use a "vm://" URI, though.
i'm also just starting them from cmd-line (the brokers
that is)
is there some implicit starting of a broker using
vm://
??

This sounds like this problem....

i.e. that you are using the vm:// URI to connect to a broker before
you have configured your
