TCP lateral cache not working

Unable to do distributed JCS caching between two Websphere Application Servers. It does caching in one server while do not share the cache with other servers.

I am testing it like this:

http://localhost:9081/TestA/put
http://localhost:9080/TestB/get

I have two cache.ccf file for each get and put methods. They are in separate webProject.

jcs.auxiliary.LTCP=org.apache.commons.jcs.auxiliary.lateral.LateralCacheFactory
jcs.auxiliary.LTCP.attributes=org.apache.commons.jcs.auxiliary.lateral.LateralCacheAttributes
jcs.auxiliary.LTCP.attributes.TransmissionTypeName=TCP
jcs.auxiliary.LTCP.attributes.TcpServers=localhost:11101
jcs.auxiliary.LTCP.attributes.TcpListenerPort=11100
jcs.auxiliary.LTCP.attributes.AllowGet=false
jcs.auxiliary.LTCP.attributes.IssueRemoveOnPut=false
jcs.auxiliary.LTCP.attributes.Receive=true
jcs.auxiliary.LTCP.attributes.PutOnlyMode=false

the other cache.ccf is as follows: 

jcs.auxiliary.LTCP=org.apache.commons.jcs.auxiliary.lateral.LateralCacheFactory
jcs.auxiliary.LTCP.attributes=org.apache.commons.jcs.auxiliary.lateral.LateralCacheAttributes
jcs.auxiliary.LTCP.attributes.TransmissionTypeName=TCP
jcs.auxiliary.LTCP.attributes.TcpServers=localhost:11100
jcs.auxiliary.LTCP.attributes.TcpListenerPort=11101
jcs.auxiliary.LTCP.attributes.AllowGet=false
jcs.auxiliary.LTCP.attributes.IssueRemoveOnPut=false
jcs.auxiliary.LTCP.attributes.Receive=true
jcs.auxiliary.LTCP.attributes.PutOnlyMode=false

Is there any other configuration I need to make. How can I start my listener ports in another server. What  ports can I use? Any advice will be valuable.

Thanks.
