    JDBC Cache loader error - Unable to build interceptor chain

    sridhar reddy Newbie

      Hi,

      I am trying to configure cache with JDBC Cacheloader programatically.

      Populated the configuration Object with each element that i specified in xml configuration. When I run program its giving an error "Exception in thread "main" org.jboss.cache.config.ConfigurationException: Unable to build interceptor chain"
      But the same is running fine when run with xml configuration.

      Can any body please help me in solving this problem.

      JBoss Cache version : 3.02

      code : CacheLoaderUtil
