    • resolveServiceEntry

      public String resolveServiceEntry(String serviceType, String domain)
      Deprecated.
      Description copied from interface: DnsResolver

      Resolves the host name for the specified service in the specified domain

      For example, if you need the host name for an LDAP server running in the domain springsource.com, you would call resolveServiceEntry("ldap", "springsource.com").

      The DNS server needs to provide the service records for this, in the example above, it would look like this: 

       _ldap._tcp.springsource.com IN SRV 10 0 88 ldap.springsource.com.
      The method will return the record with highest priority (which means the lowest number in the DNS record) and if there are more than one records with the same priority, it will return the one with the highest weight. You will find more informatione about DNS service records at Wikipedia.
