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.
The default SearchControls specifies that the search is to be performed in the named context ( SearchControls.ONELEVEL_SCOPE). This default is used in the examples in the Search Filters section.
In addition to this default, you can specify that the search be performed in the entire subtree or only in the named object.
A search of the entire subtree searches the named object and all of its descendants. To make the search behave in this way, pass SearchControls.SUBTREE_SCOPE to SearchControls.setSearchScope() as follows.
// Specify the ids of the attributes to return
String[] attrIDs = {"sn", "telephonenumber", "golfhandicap", "mail"};
SearchControls ctls = new SearchControls();
ctls.setReturningAttributes(attrIDs);
ctls.setSearchScope(SearchControls.SUBTREE_SCOPE);
// Specify the search filter to match
// Ask for objects that have the attribute "sn" == "Geisel"
// and the "mail" attribute
String filter = "(&(sn=Geisel)(mail=*))";
// Search the subtree for objects by using the filter
NamingEnumeration answer = ctx.search("", filter, ctls);
This example
searches the context ctx's subtree for entries that satisfy the specified filter. It finds the entry "cn= Ted Geisel, ou=People" in this subtree that satisfies the filter.
# java SearchSubtree >>>cn=Ted Geisel, ou=People attribute: sn value: Geisel attribute: mail value: Ted.Geisel@JNDITutorial.example.com attribute: telephonenumber value: +1 408 555 5252
You can also search the named object. This is useful, for example, to test whether the named object satisfies a search filter. To search the named object, pass SearchControls.OBJECT_SCOPE to setSearchScope().
// Specify the ids of the attributes to return
String[] attrIDs = {"sn", "telephonenumber", "golfhandicap", "mail"};
SearchControls ctls = new SearchControls();
ctls.setReturningAttributes(attrIDs);
ctls.setSearchScope(SearchControls.OBJECT_SCOPE);
// Specify the search filter to match
// Ask for objects that have the attribute "sn" == "Geisel"
// and the "mail" attribute
String filter = "(&(sn=Geisel)(mail=*))";
// Search the subtree for objects by using the filter
NamingEnumeration answer =
ctx.search("cn=Ted Geisel, ou=People", filter, ctls);
This example tests whether the object "cn=Ted Geisel, ou=People" satisfies the given filter.
# java SearchObject >>> attribute: sn value: Geisel attribute: mail value: Ted.Geisel@JNDITutorial.example.com attribute: telephonenumber value: +1 408 555 5252
The example found one answer and printed it. Notice that the name of the result is the empty string. This is because the name of the object is always named relative to the context of the search (in this case, "cn=Ted Geisel, ou=People").
