Shalin Shekhar Mangar commented on SOLR-256:
--------------------------------------------
Hoss, thanks for the comments.
* Specifying port=0 to ServiceUrl does not work, it blindly tries to connect to
localhost on port 0 and fails with a java.rmi.ConnectException. We can try to
do something like this:
{code}
ServerSocket server = new ServerSocket(0);
int port = server.getLocalPort();
server.close();
// Use the port
{code}
However it will not be reliable on every environment. I can put this into a
loop and retry a fixed number of times before failing. That should be good
enough.
* Agreed
* Copy/paste error :)
* That's a very good idea.
* Not sure if it really matters but that's very easy to do.
I shall give a patch shortly.

> This patch adds JMX capability to get statistics from all the SolrInfoMBean.
> The implementation is done such a way to minimize code changes.
> In SolrInfoRegistry, I have overloaded Map's put and remove methods to
> register and unregister SolrInfoMBean in MBeanServer.
> Later on, I am planning to use register and unregister methods in
> SolrInfoRegistry and removing getRegistry() method (Hiding the map instance
> to other classes)
