My configuration is: @Bean public InfinispanRemoteConfigurer infinispanRemoteConfigurer() { return () -> new ConfigurationBuilder() .addServer() .host(host) .port(Integer.parseInt(port)) .statistics() .enable() .jmxEnable() .build(); } And I have also tried with this one: @Bean public SpringRemoteCacheManager cacheManager() { return new SpringRemoteCacheManager(infinispanCacheManager()); } @Bean public RemoteCacheManager infinispanCacheManager() { ConfigurationBuilder builder = new ConfigurationBuilder(); builder.addServer() .host(host) .port(Integer.parseInt(port)) .statistics() .enable() .jmxEnable(); return new RemoteCacheManager(builder.build()); } But both return me the same error.
