[jboss-user] [JBossCache] - Re: Cache not accessible from different methods ?

[manik.surtani@jboss.com]

The reason is that in both methods (populateCache and displayCacheContents) you're creating a new cache instance.  And if these instances are not configured to be clustered, they won't see state in each other.

Bruce's case probably worked since when you retrieve the cache from an MBean server rather than create a new one each tme, both cases use the same cache.

So what you want is probably something like this:


  | 
  | private PojoCache pojoCache;
  | 
  | private void createCache() {
  |    pojoCache = PojoCacheFactory.createCache("META-INF/service.xml", true);
  | }
  | 
  | 
  | private void populateCache() {
  |   Person person = new Person("Chris","Harris",32);
  |   pojoCache.attach("/cachedobjects/person", person);
  |   Person dummyPerson = (Person)pojoCache.find("/cachedobjects/person");
  | 		log.info("Name = " + dummyPerson.getName());
  | }
  | 
  | private void displayCacheContents() {
  |   Person person = (Person)pojoCache.find("/cachedobjects/person");
  | 		log.info("Name = " + person.getName());
  | }
  | 
  | public static void main(String args[]) {
  |   MyApp app = new MyApp();
  |   myApp.createCache();
  |   myApp.populateCache();
  |   myApp.displayCacheContents();
  | }
  |
