Searching a Subtree in the Directory
This example searches a subtree in the directory for objects by using a search filter. 

 
 try {
     SearchControls ctls = new SearchControls();
     ctls.setSearchScope(SearchControls.SUBTREE_SCOPE);
  
     // Specify the search filter to match
     // Ask for objects that have attribute "sn" ==
     // Geisel and the "mail" attribute
     String filter = "(&(sn=Geisel)(mail=*))";
     
     // Search for objects using filter
     NamingEnumeration enum = ctx.search("", filter,
       ctls);
     
     while (enum.hasMore()) {
         SearchResult entry = (SearchResult)enum.next();
         process(entry);
     }
 } catch (NamingException e) {
 }
