Gets the value of the JMX name base that will be used as part of the name assigned to JMX enabled pools created with this configuration instance.

Usage

From source file:JDBCPool.dbcp.demo.sourcecode.BaseGenericObjectPool.java

/**
 * Registers the pool with the platform MBean server.
 * The registered name will be/*w w  w  .ja v a 2s .  c om*/
 * <code>jmxNameBase + jmxNamePrefix + i</code> where i is the least
 * integer greater than or equal to 1 such that the name is not already
 * registered. Swallows MBeanRegistrationException, NotCompliantMBeanException
 * returning null.
