I given the below configuration in the cache server side....

     <cache-mapping>
<cache-name>NearCache</cache-name>
<scheme-name>example-near</scheme-name>
</cache-mapping>
</caching-scheme-mapping>

<near-scheme>
     <scheme-name>example-near</scheme-name>
     <front-scheme>
     <local-scheme>
     <scheme-ref>example-local</scheme-ref>
     </local-scheme>
     </front-scheme>

     <remote-cache-scheme>
     <scheme-ref>example-remote</scheme-ref>
     </remote-cache-scheme>
</back-scheme>
</near-scheme>

PLease provide the configurastion for the nearcache topology....
Thank you.

You are missing the example-local
<local-scheme>
<scheme-ref>example-local</scheme-ref>
</local-scheme>
for example,
<local-scheme>
      <scheme-name>example-local</scheme-name>
      <eviction-policy>HYBRID</eviction-policy>
      <high-units>{back-size-limit 0}</high-units>
      <unit-calculator>BINARY</unit-calculator>
      <expiry-delay>{back-expiry 1h}</expiry-delay>
</local-scheme>Examples can be found in the coherence.jar that contains coherence-cache-config.xml
