I have configured loadbalancer as belows and I the request are not redirecting to the correct servers. Please help me on this. 

We have 2 jboss machines running on 
	1) 10.239.20.193 Port 8080
	2) 10.239.96.181 Port 8080

We have installed Apache with mod_jk in another machine (10.239.19.149) 
and have done the following configurations: 

Configuration changes in JBoss Node 1 (10.239.20.193 Port 8080)
a) In server/all/deploy/jbossweb-tomcat55.sar/server.xml 
	we have modified the jvmRoute tag in <Engine tag to "node1"
	
	
b) Modified the useJK in the /server/all/deploy/jbossweb-tomcat55.sar/META-INF/jboss-service.xml to true 
	true

Configuration changes in JBoss Node 2 (10.239.96.181 Port 8080)
a) In server/all/deploy/jbossweb-tomcat55.sar/server.xml
	we have modified the jvmRoute tag in <Engine tag to "node2"
	

b) Modified the useJK in the /server/all/deploy/jbossweb-tomcat55.sar/META-INF/jboss-service.xml to true 
	true

Configuration changes in Load balancer machine: 
a) Modified httpd.conf
		Included the following block at the end: 
		
		# Include mod_jk's specific configuration file
	Include conf/mod-jk.conf

b) Create mod-jk.conf with the following contents: 
		# Load mod_jk module
		# Specify the filename of the mod_jk lib
		LoadModule jk_module modules/mod_jk.so
		
		# Where to find workers.properties
		JkWorkersFile conf/workers.properties
		
		# Where to put jk logs
		JkLogFile logs/mod_jk.log
		
		# Set the jk log level [debug/error/info]
		JkLogLevel info 
		
		# Select the log format
		JkLogStampFormat  "[%a %b %d %H:%M:%S %Y]"
		
		# JkOptions indicates to send SSK KEY SIZE
		JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
		
		# JkRequestLogFormat
		JkRequestLogFormat "%w %V %T"
		
		# Mount your applications
		JkMount /ppm/* loadbalancer
		
		# You can use external file for mount points.
		# It will be checked for updates each 60 seconds.
		# The format of the file is: /url=worker
		# /examples/*=loadbalancer
		JkMountFile conf/uriworkermap.properties               
		
		# Add shared memory.
		# This directive is present with 1.2.10 and
		# later versions of mod_jk, and is needed for
		# for load balancing to work properly
		JkShmFile logs/jk.shm 
		
		# Add jkstatus for managing runtime data
		<Location /jkstatus/>
		JkMount status
		Order deny,allow
		Deny from all
		Allow from 127.0.0.1
		
c) Created uriworker.properties with the following contents: 

		# Simple worker configuration file
		
		# Mount the Servlet context to the ajp13 worker
		/jmx-console=loadbalancer
		/jmx-console/*=loadbalancer
		/web-console=loadbalancer
		/web-console/*=loadbalancer

d) Created worker.properties with the following contents: 
		# Define list of workers that will be used
		# for mapping requests
		worker.list=loadbalancer,status
		
		# Define Node1
		# modify the host as your host IP or DNS name.
		worker.node1.port=8080
		worker.node1.host=10.239.20.193
		worker.node1.type=ajp13
		worker.node1.lbfactor=1
		worker.node1.cachesize=10
		
		# Define Node2
		# modify the host as your host IP or DNS name.
		worker.node2.port=8080
		worker.node2.host=10.239.96.181
		worker.node2.type=ajp13
		worker.node2.lbfactor=1
		worker.node2.cachesize=10
		
		# Load-balancing behaviour
		worker.loadbalancer.type=lb
		worker.loadbalancer.balance_workers=node1,node2
		worker.loadbalancer.sticky_session=1
		#worker.list=loadbalancer
		
		# Status worker for managing load balancer
		worker.status.type=status
		
When we try to hit the apache mod-jd with the following url we get the output in the log file as
