WLST Script To create a JMS server
In this blog post, we are going to write a WLST script to create a JMS server. We are going to create a JMS server using WLST after reading the information from the properties file. The following code can be downloaded from the following link:
1. The first step is to create a properties file and name it as domain.properties
#***************************************************** # Security Info #***************************************************** ADMIN_USERNAME=weblogic ADMIN_PASSWORD=weblogic01 ADMIN_URL=t3://192.168.1.9:8001 DOMAIN_NAME=togodomain #***************************************************** # Server Info #***************************************************** SERVER_NAME=AdminServer #***************************************************** # JMS Info #***************************************************** JMS_SERVER_NAME=jmserver1
2. In the next step we are going to write a utility to read the properties file in a given format
#! /usr/bin/python
#****************************************************************************
# File: utils.py
#****************************************************************************
from java.lang import System
#****************************************************************************
# def notNullOrEmpty()
#****************************************************************************
def notNullOrEmpty(val):
return val != None and len(val) != 0
#****************************************************************************
# def substitute()
#****************************************************************************
def substitute(orig, subs):
startIndex = orig.find(‘${‘)
#print ‘startIndex =’, startIndex
if startIndex == -1:
return orig
endIndex = orig.find(‘}’, startIndex)
#print ‘endIndex =’, endIndex
if endIndex == -1:
return orig
substitutionKey = orig[startIndex + 2:endIndex]
value = System.getProperty(substitutionKey)
if subs.has_key(substitutionKey):
value = subs[substitutionKey]
if value != None:
return orig[0:startIndex] + value + substitute(orig[endIndex + 1:], subs)
if len(orig) == endIndex + 1:
print ‘WARNING: No substitution found for key:’, orig
return orig
else:
return orig[0:endIndex + 1] + substitute(orig[endIndex + 1], subs)
#****************************************************************************
# def loadOrderedProps
#****************************************************************************
def loadOrderedProps(filename):
def split(line):
index = line.find(‘=’)
if index == -1:
return None
else:
return (line[:index], line[index + 1:])
propLines = open(filename, ‘r’).readlines()
propLines = [line.strip() for line in propLines]
propLines = [line for line in propLines if len(line) > 0 and not line.startswith('#')]
propLines = [split(line) for line in propLines]
propLines = [line for line in propLines if line]
return propLines
#****************************************************************************
# def loadProperties()
#****************************************************************************
def loadProperties(propFile):
props = {}
originalProps = loadOrderedProps(propFile)
for key, value in originalProps:
#print ‘ KEY: [' + key + ']‘
value = substitute(value, props)
#print ‘ VALUE: [' + value + ']‘
props[key] = value
return props
#****************************************************************************
# def getValue
#****************************************************************************
def getValue(propKey, defaultKey, properties):
if properties.get(propKey) != None:
val = properties[propKey]
else:
if properties.get(defaultKey) != None:
val = properties[defaultKey]
else:
val = ”
return val
#****************************************************************************
# def getKeyValue
#****************************************************************************
def getKeyValue(propkey, properties):
if properties.get(propkey) != None:
val = properties[propkey]
else:
val = ”
return val
3. This is the step where we are going to write the WLST online script to create the JMS server.

We also have a tutorial on how to create a jms server using JMX.
