Pre-loading the Cache from Database during application start-up

Question

We are using Spring, Hibernate, Oracle Coherence 3.5.2 Weblogic Webservices
Our requirement is to pre-load the cache during the application start-up most probably during Authentication/Authorization Service is invoked.
We plan to load the data for other services from database into Coherence cache so that whenever user access that particular service he ends up hitting the Cache instead of database.
We would greatly appreciate sample code snippets on how to write CacheInitializerBean with marker to demonstrate the state of cache.

Answer 1

Hi Rob,
Thanks for pointing to the article: Pre-Loading the Cache
In fact i already looked at that article before posting. It just mentions how to load the data from database into Cache.
What i am looking for is how to make this happen during application start-up. This is my first hurdle.
The second one is as mentioned in the article http://coherence.oracle.com/display/COH35UG/Pre-Loading+the+Cache
i wrote following code which never gets populated into cache. Not sure whats going wrong even though i see Hibernate loadAll() method loading all the objects in the console
public   void populateCache() throws SQLException
    Map<Long, Object>  buffer = new HashMap<Long, Object>();
    int count = 0;
     List<Contract> contractList = this.getHibernateTemplate().loadAll(Contract.class);
     log.debug("contractList size="+contractList.size());
     for(Contract contract : contractList)
         Long key   = new Long(contract.getId());
         Object  value = contract;
         buffer.put(key, value);
         // this loads 1000 items at a time into the cache
         if ((count++ % 1000) == 0)
              contractCache.putAll(buffer);
             buffer.clear();
     if (!buffer.isEmpty())
          contractCache.putAll(buffer);
    }We would greatly appreciate your time in helping us resolving two hurdle blocks.
