How to build an ObjectName pattern to list all objs of type=ServerConnector

Question

Hi,
I would like to list all the MX objects of type=ServerConnector. How to build the pattern?
The example below doesn't work (with pattern: resin:type=ServerConnector").
It works when I want to list all objects and use pattern ("resin:*") or when I choose a specific ("resin:type=ServerConnector,name=b");
Thanks for any advice,
Ala
{code}
Object Name pattern = new ObjectName("resin:type=ServerConnector");
MBeanServer mBeanServer = Jmx.getGlobalMBeanServer();
Set poolNames = mBeanServer.queryNames(pattern, null);
{code}
And here all listed MX objects:
resin:type=SessionManager,Host=default,WebApp=/
resin:type=ServerConnector,name=i
resin:type=ServerConnector,name=h
resin:type=ServerConnector,name=b
resin:type=Resin
resin:type=ServerConnector,name=j
resin:type=ProxyCache
resin:type=Host,name=default
resin:type=ServerConnector,name=c
resin:type=ServerConnector,name=e
resin:type=Port,name=192.68.1.50-6802
resin:type=ServerConnector,name=g
resin:type=ServerConnector,name=a
resin:type=ThreadPool
resin:type=WebApp,Host=default,name=/
resin:type=WebApp,Host=default,name=/mya
resin:type=ConnectionPool,Host=default,WebApp=/mya,name=jdbc/mya
resin:type=ServerConnector,name=f
resin:type=Cluster,name=cluster1
resin:type=ServerConnector,name=d
resin:type=SessionManager,Host=default,WebApp=/mya
resin:type=Server

You need to add a comma and asterisk to your pattern:
Object Name pattern = new ObjectName("resin:type=ServerConnector,*");The pattern you are using will only match a single MBean with that exact name. There has to be an asterisk in the string in order for it to match like-named MBeans which have key/value pairs other than those in the string.
For more on this, search in this javadoc for the string "property pattern":
