I am trying to use the JDBC Cache Loader to persist TreeCache to DB, Here is how i do it.... public void configureCache(){ try { System.out.println("Inside configureCache"); Properties properties = new Properties(); try { properties.load(new FileInputStream("jdbc-cache.properties")); } catch (IOException e) { e.printStackTrace(); } PropertyConfigurator config = new PropertyConfigurator(); config.configure(cache,getConfigFile()); JDBCCacheLoader jdbcCacheLoader=new JDBCCacheLoader(); jdbcCacheLoader.setConfig(properties); jdbcCacheLoader.setCache(cache); jdbcCacheLoader.create(); jdbcCacheLoader.start(); Fqn fqn=new Fqn("PaymentCache"); System.out.println(cache.get(fqn));//I get NULL HERE } catch(Exception e) { e.printStackTrace(); } I am following the life cycle of Loader as described in API fo CacheLoader interface. But i do a get on TreeCache cache i get a null pointer, looks like the cache is not getting any thing from loader the data is avaliable on the DB i can directly do a get on jdbccacheloader and get the info. Where am i going wrong is this the right way to attach a loader to TreeCache.... Thanks in advance View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959717#...
