How to retrieve a Connection Pool name form a DataSource

Question

I couldn't find a way of retrieving JDBC Connection Pool name (or JDBCConnectionPoolRuntimeMBean
object) from a DataSource object.
I use the standard approach to get a Datasource:
Context ctx = null;
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL, sJndiUrl);
ctx = new InitialContext(ht);
dataSource = (javax.sql.DataSource) ctx.lookup (s);
It works fine !
I know that each datasource is mapped to a connection pool & need to retrieve
either connection pool's name or JDBCConnectionPoolRuntimeMBean object from the
datasource, but didn't find any function that would allow me to do that.

I've just found a solution for that, but didn't like it too much because it uses
undocumented class & function. Probably BEA should include the documentation for
weblogic.jdbc.common.internal.RmiDataSource or provide an alternative way of getting
JDBCConnectionPoolRuntimeMBean object from a datasource. The solution is below:
RmiDataSource dataSource = (RmiDataSource) ctx.lookup (s);
Properties propDs = dataSource.getDriverProperties();
String sPoolName = propDs.getProperty("connectionPoolID");
MBeanHome mbeanAdmin = (MBeanHome)ctx.lookup(MBeanHome.LOCAL_JNDI_NAME);
JDBCConnectionPoolRuntimeMBean jdbcPool = (JDBCConnectionPoolRuntimeMBean)
mbeanAdmin.getRuntimeMBean(sPool,"JDBCConnectionPoolRuntime");
Now I have JDBCConnectionPoolRuntimeMBean object that I can use to access different
kind of pool's counts, e.g. number of current connections, number of leaked connections,
etc. I need this information to monitor pool programmatically & send alerts to
a suport team if e.g. number of active connections reaches a certain threshold.
If there is a better way of doing this please let me know.
Please also notice that I don't want an application to know anything about the
Connection Pool being used, an application should know only about a datasource.
Thanks.
