    Problem with distributed cluster cache

    spring hibernate Newbie

      I have written a sample code for distributed clustered caching.please let me know this is correct and how to test this program without any server.

       

      I have created a simpleCacheExample class and created instance for EmbeddedCacheManger.From there Iam getting cache.

       

      public class SimpleCacheExample {

       

          public static void main(String[] args) {

            

              EmbeddedCacheManager ecm=createCacheManagerProgramatically();

              Cache cache=ecm.getCache();

            

            

            

                  if(!cache.isEmpty()){

                      System.out.println("cache hit");

                  System.out.println(cache.get(1));

                  }

                  else

                  {

                      System.out.println("cache miss putting element in cache");

                      cache.put(1, "testing");

                    

                  }

                

            

                

            

                

       

          }

          private static EmbeddedCacheManager createCacheManagerProgramatically() {

                return new DefaultCacheManager(

                      GlobalConfigurationBuilder.defaultClusteredBuilder()

                            .transport().addProperty("configurationFile", "jgroups.xml")

                            .build(),

                      new ConfigurationBuilder()

                            .clustering().cacheMode(CacheMode.REPL_SYNC)

                            .build()

                );

             }

       

       

      }

      Do i need to do any extra configuration apart from this for above example
