The Multicast DNS (mDNS) [RFC 6762] & DNS-Based Service Discovery (DNS-SD) [RFC 6763] in Java (mdnsjava) project is an extension of dnsjava (dnsjava.org) that implements Multicast DNS (mDNS) [RFC 6762] and DNS-Based Service Discovery (DNS-SD) [RFC 6763] in Java (aka. Bonjour in Java)
Unlike other mDNS/DNS-SD implementations mdnsjava does not artificially bind the mDNS and DNS-SD functionality into a single API, instead treating each as a separate feature that is independent from, but related to, the other. This allows clients to use Multicast DNS (mDNS) RFC 6762 for name resolution without having to worry about service discovery and simplifies the use of DNS-Base Service Discovery using plain old Unicast DNS (mDNS can be used as a substitiute for DNS for name resolution and DNS can be used as a substitute for mDNS for service discovery).
