Strange -Dactivemq.base behavior
Hi,
I'm trying to change the location of -Dactivemq.base. In the activemq
script, you can do this by setting the environment variable ACTIVEMQ_BASE to
something besides the default, which is $ACTIVEMQ_HOME.
I set ACTIVEMQ_BASE=/tmp, and ran activemq with a simplified version of the
conf/activemq.xml file. I verified (by looking at "ps") that
-Dactivemq.base=/tmp when activemq executes. I set it to /tmp so the files
for /tmp/data will go there. (Just for this test).
When I do this, it appears that not only does it not put data into /tmp as
requested, but it creates an actual directory called "${activemq.base}" in
the current working directory. It puts the "data" directory below that,
along with all the usual subdirectories below "data".
Any ideas what I'm doing wrong, or is this a bug? Here is the simple.xml
file I'm using:
<beans

Hi,
you need to define PropertyPlaceholderConfigurer in your xml file, in order
to use system properties. Something like
<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"/>
will do the trick.
Cheers
