analytics/wlp/clients/jython

The script in this directory provides a utility for establishing a Liberty
JMX MBean server connection. This has been tested for Jython 2.5.3.

1) Environment set up

a. Set the classpath to include the restConnector.jar
e.g) WINDOWS
set CLASSPATH=${wlp.install.dir}\clients\restConnector.jar
e.g) LINUX / UNIX
export CLASSPATH=${wlp.install.dir}/clients/restConnector.jar

b. Set the jython path to include the restConnector.py
e.g) WINDOWS
set JYTHONPATH=${wlp.install.dir}\clients\jython\restConnector.py
e.g) LINUX / UNIX
export JYTHONPATH=${wlp.install.dir}/clients/jython/restConnector.py


2) Examples

The following two examples show how to get a Liberty JMX MBean server
connection using the utility:

Example 1 - Simple connection using connector.connect(host,port,user,password)

from restConnector import JMXRESTConnector
JMXRESTConnector.trustStore = "c:/key.jks"
JMXRESTConnector.trustStorePassword = "Liberty"

connector = JMXRESTConnector()
connector.connect("foo.bar.com",9443,"theUser","thePassword")
mconnection = connector.getMBeanServerConnection()
# mconnection.invoke(...)
connector.disconnect()

Example 2 - Advanced connection using connector.connect(host,port,map) with
user provided properties

import java
import javax
import jarray
import com.ibm.websphere.jmx.connector.rest
import com.ibm.ws.jmx.connector.client.rest

map=java.util.HashMap()
map.put("jmx.remote.provider.pkgs","com.ibm.ws.jmx.connector.client")
map.put(javax.management.remote.JMXConnector.CREDENTIALS,jarray.array(["theUser","thePassword"],java.lang.String))
map.put(com.ibm.websphere.jmx.connector.rest.ConnectorSettings.READ_TIMEOUT,2*60*1000)
map.put(com.ibm.websphere.jmx.connector.rest.ConnectorSettings.DISABLE_HOSTNAME_VERIFICATION, True)

connector = JMXRESTConnector()
connector.connect("foo.bar.com",9443,map)
mconnection = connector.getMBeanServerConnection()
# mconnection.invoke(...)
connector.disconnect()

The following example shows how to register a notification listener:

Example 3 - Notification listener

import java
import javax

from restConnector import JMXRESTConnector
from restConnector import BaseNotificationListener

class SampleNotificationListener(BaseNotificationListener):
def __init__(self):
pass

def handleNotification(self,notification,handback):
print "Notification received:"
print " Source: " + notification.getSource().toString()
print " Type: " + notification.getType()
print " Message: " + notification.getMessage()

# main starts here

JMXRESTConnector.trustStore = "c:/key.jks"
JMXRESTConnector.trustStorePassword = "Liberty"

connector = JMXRESTConnector()
connector.connect("foo.bar.com",9443,"theUser","thePassword")
mconnection = connector.getMBeanServerConnection()

listener=SampleNotificationListener()
handback=java.lang.Object()

notifier1=javax.management.ObjectName("web:name=Notifier1")
mconnection.addNotificationListener(notifier1,listener,None,handback)

3) API

* JMXRESTConnector.trustStore - Set the path to the SSL key store file
* JMXRESTConnector.trustStorePassword - Set the password for the key
* JMXRESTConnector.connect(host,port,user,password) - Create a connector to the server
* JMXRESTConnector.connect(host,port,map) - Create a connector with user properties
* JMXRESTConnector.getMBeanServerConnection - Get a connection to the MBean server
* JMXRESTConnector.disconnect() - Close the connection
