Hi There,
We are building a light j2ee framework for our company. We are using
log4j for logging. One important objetive of our framework is to make
applications manageable, and for that purpose we use JMX.
We have planned to use log4j own jmx implementation. Yes, I know its
already beta, but it has the basic functionallity right now.
I've been reading the code and I have found an issue that could be
an error. I´m not sure so I need your help.
HierarchyDynamicMBean builds other MBeans depending on log4j
configuration. Those "child" MBeans are created using a domain called
"log4j".
This is a problem for us. In our application server we have an
instance of log4j for each application installed. We plan to use Websphere's
own MBeanServer, otherwise admins will have to use different ports to see
all the MBeans that the server is running.
If log4j jmx uses a hardcoded "log4j" string as a domain name we are
going to have some problems. First: two different log4j instances wont be
able to register their MBeans as the second log4j instance will recibe an
exception for trying to register an MBean twice. The other issue is that
even it it was possible to register them twice, it wont be possible to
recognize with one corresponds with an application, as all them look the
same.
The fastest solution for me is using only one log4j instance for the
whole server. But this solution introduces some dependendes between
applications that we´d like to avoid.
Any opinion?
cheers.
