[jboss-dev-forums] [JBoss Cache Development] - cache NULL each time I hit a button

barbara b [http://community.jboss.org/people/barbaraboie] created the discussion "cache NULL each time I hit a button" To view the discussion, visit: http://community.jboss.org/message/579794#579794 -------------------------------------------------------------- Hello Before, I used a previous version of JBoss Cache where I simply could use in every bean CacheProvider: @In(create=true) CacheProvider cacheProvider  public void method(){           ...           List) cacheProvider.get("tree-"+id);       if (rubriek == null){                     cacheProvider.put("tree-"+id,getTree());        }           ... }  and the caching worked just fine through the whole site. Now I'm trying to work with JBoss Cache 3.2.5.GA and it's not working. Every time I click on a button, the cache is empty. I started changing the code in each bean into CacheFactory factory = new DefaultCacheFactory(); Cache cache = factory.createCache("cache-configuration.xml"); public void method(){           ...           Fqn fqn = Fqn.fromString("/id"+id)       List) cache.get(fqn,"tree");             if (rubriek == null){                     cache.put(fqn,"tree",getTree());           }           ... }   When I tried this code, I saw that the cache was emptied each time I hit a button. I thought the problem was that I start in each bean a new Cache by using factory.createCache("cache-configuration.xml") So I made a new class that can be used in every bean, so that the cache is only started once: public class CacheHelper{           public static CacheFactory  factory = new DefaultCacheFactory();            public static Cache cache = factory.createCache("cache-configuration.xml"); }   and in each bean public void method(){           ...            List) CacheHelper.cache.get(fqn,"tree");             if (rubriek == null){                      CacheHelper.cache.put(fqn,"tree",getTree());           }           ... } But the cache is still empty each time I click on a button. Is there anyone who can tell me what I'm doing wrong? Thanks a lot in advance! Barbara O, this is my cache-configuration.xml -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/579794#579794] Start a new discussion in JBoss Cache Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
