Constructor Detail

JMXRMIAdaptor

public JMXRMIAdaptor(java.lang.String serverName)
              throws JBossNotAvailable

Parameters:

serverName - The name of the server machine.

Throws:

JBossNotAvailable - when there is a naming exception, usually indicating that the JBoss instance is not running.
