Spring Batch Admin Manager implementation is not updated since January 2015.
Is there something else that have to be used instead? Or should I still use Spring Batch Admin Manager to provide some generic UI for Spring Batch application?
Assuming you mean the Spring Batch Admin v1.3.1 release then:
Is there something else? Yes, if your spring batch application is a spring boot variant have a look at https://github.com/codecentric/spring-boot-admin and how to configure it checkout http://codecentric.github.io/spring-boot-admin/1.4.1/#getting-started and https://blog.codecentric.de/en/2014/09/spring-boot-admin-first-official-release/
