Infinispan cache.put does not work - infinispan

Question

I have created a two node cluster running Infinispan cache in replication mode. I see the cache comes up fine. and both the nodes connect to each other. I am here using TreeCache Api to convert the Map based structure to tree based as below:
private static Cache<Object, Object> Cache1;
private static TreeCache<Object, Object> Cache;
Cache1 = new DefaultCacheManager("infinispan.xml").getCache();
Cache = new TreeCacheFactory().createTreeCache(Cache1);
If i call Cache.put , I dont get any error but the entry does not get saved to the cache. I confirmed it by getting the data again which returns NULL.
Cache.put(fqn,key, value);
if(Cache.get(fqn, key) == null)
{
System.out.println("Entry is not saved");
}
Below is the config file,
<?xml version="1.0" encoding="UTF-8"?>
<infinispan xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="urn:infinispan:config:5.3 http://www.infinispan.org/schemas/infinispan-config-5.3.xsd"
xmlns="urn:infinispan:config:5.3">

<globalJmxStatistics enabled = "true" allowDuplicateDomains = "true"/>
<transport clusterName = "test_cluster">
<properties>
<property name="configurationFile" value="tcp.xml" />
</properties>
</transport>
</global>
<default>
<clustering mode="replication">
<async asyncMarshalling="true" useReplQueue="true" replQueueInterval="10" replQueueMaxElements="100" />
<stateTransfer timeout="2000000"/>
</clustering>
<invocationBatching enabled = "true"/>
<locking isolationLevel = "REPEATABLE_READ"
writeSkewCheck = "false"
concurrencyLevel = "1000"/>
<jmxStatistics enabled="true"/>
</default>
</infinispan>
Is it that I am missing to initialize any thing?
