Cache.put with Timespan doesnt evicy teh cache entry.

[sudheerk84]

I  and testing teh cache fucntionalities of which i am trying to add an entry which shoudl be cleared up after teh given time span. This doesnt seem to work. Have i misunderstood teh API ?

The code lools as follows which i am calling in a loop

        Cache cache = manager.getCache("orderCache");

        cache.put(key, value, 3L, TimeUnit.MILLISECONDS);

        System.out.println("size" + cache.size());

The  size of  cache is same as loop interation . Shouldnt the entry be cleared ?

My cache configuration is as follows

       <namedCache name="orderCache">

              <clustering mode="distribution">

                  <sync/>

                  <hash

                     numOwners="2"

                     rehashWait="120000"

                     rehashRpcTimeout="600000"

                  />

               </clustering>

         </namedCache>

Looks liek teh issue coudl be with the size() method i use.

Reading this - http://community.jboss.org/wiki/UsingtheCacheAPI#The_Cache_interface i found that the size may not give teh accurate size even though my cache is a local instance.

yep. Reading the actual value after expiration time(in your case 3millis) should return null.

Yes Markus . I did try that it works fine. Thank you.

I was writing a wrapper to the exact cache implementation and have decided not to give methods like size(), getKeys() etc which may  not work in a distributed env,

Indeed, these methods are there rather for debugging purposes.
