JDBC Cache loader error - Unable to build interceptor chain
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.
