Currently all the config files are obtained from the classloader via getResources with a
harcoded filename. By default we have as a minimum jbm-configuration.xml, jbm-security.xml
and jbm-jms.xml altho an optional jbm-queues.xml canbe used.
When we run from within a distro, i.e. './run.sh', all these config files are
conatined in the config dir which is added to the classpath by the run.sh script.
We need to be able to specify different config files on starting the server, this is for
running clustered and running examples withdifferent configurations.
There are a few ways of doing this.
1. simply specify a different config directory on startup, the script will change the
classpath and the config files will be loaded from a different directory using the same
filenames. i.e.
./run.sh -cjbm-config,dir=../examples/common/config
2. Specify a different filename for each file. This way in the code we use the default
filenames or use the system property if set. i.e.
./run.sh -Djbm.conf=foo -Djbm.jms.conf=bar -Djbm.security.conf=foobar
We just have to make sure that the location of the alternative config files is in the
classpath or the user specifies a full path.
3. Inject the config filenames into the deployers via thebean descriptor. so the default
beans file would contain something like:
| <bean name="Configuration"
class="org.jboss.messaging.core.config.impl.FileConfiguration">
| <property
name="config">${JBM_HOME}/config/jbm-configuration.xml</property>
| </bean>
|
the to run an example we run
./run.sh ../examples/common/config/jbm-example-beans.xml
and we change the configuration in that to
| <bean name="Configuration"
class="org.jboss.messaging.core.config.impl.FileConfiguration">
| <property
name="config">${JBM_HOME}../examples/common/config/example-configuration.xml</property>
|
| </bean>
Or whatever the user wants. This is also easier when deploying multiple instances within
the AS., with 1 and 2 you couldn't do this
My option is for the latter
