The Java Tutorials have been written for JDK 8. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available.
See Java Language Changes for a summary of updated language features in Java SE 9 and subsequent releases.
See JDK Release Notes for information about new features, enhancements, and removed or deprecated options for all JDK releases.
In the JDK releases prior to 5.0, there is no direct way of obtaining the Distinguished Name (DN) from the search results. The SearchResults.getName() method always returns the name that is relative to the context on which the search is performed. In order to get the absolute, or full name of the search entry some amount of book-keeping is required to track the ancestor contexts. Two new APIs below are added in JDK 5.0 to retrieve the absolute name from the NameClassPair, whenever a search, list, or listBindings operation is performed on a context:
Here is an example that retrieves DNs from an LDAP search:
public static void printSearchEnumeration(NamingEnumeration retEnum) { try { while (retEnum.hasMore()) { SearchResult sr = (SearchResult) retEnum.next(); System.out.println(">>" + sr.getNameInNamespace()); } } catch (NamingException e) { e.printStackTrace(); } }
