PingJndi

public PingJndi()
Method Detail

getLookupNames

public java.lang.String[] getLookupNames()
Get the names of JNDI bindings that should be queried on each host

Specified by:
getLookupNames in interface PingJndiMBean (src)
Returns:
the array of target names to test

setLookupNames

public void setLookupNames(java.lang.String[] names)
Set the names of JNDI bindings that should be queried on each host

Specified by:
setLookupNames in interface PingJndiMBean (src)
Parameters:
names -

getProviderURLPattern

public java.lang.String getProviderURLPattern()
Get the Context.PROVIDER_URL regular expression.

Specified by:
getProviderURLPattern in interface PingJndiMBean (src)
Returns:
the regular expression containing the host, for example 'jnp://(host):1099/'

setProviderURLPattern

public void setProviderURLPattern(java.lang.String regex)
Set the regular expression containing the hostname/IP address of the JNDI provider. This expression is used to build the JNDI Context.PROVIDER_URL for each node in the cluster. The expression should contain a "(host)" component that will be replaced with the cluster node hostname.

Specified by:
setProviderURLPattern in interface PingJndiMBean (src)
Parameters:
regex - the regular expression containing the host, for example 'jnp://(host):1099/'

membershipChanged

public void membershipChanged(java.util.ArrayList removed,
                              java.util.ArrayList added,
                              java.util.ArrayList members,
                              java.lang.String logCategoryName)
The TopologyMonitorService trigger callback operation.

Specified by:
membershipChanged in interface PingJndiMBean (src)
Parameters:
removed - ArrayList of nodes that were removed
added - ArrayList of nodes that were added
members - ArrayList of nodes currently in the cluster
logCategoryName - the log4j category name used by the TopologyMonitorService. This is used for logging to integrate with the TopologyMonitorService output.
