Searching the Directory By Using a Search Filter
This example searches the directory for objects by using a search filter. 

 
 try {
     // Specify the ids of the attributes to return
     String[] attrIDs = {"sn", "telephonenumber",
       "golfhandicap", "mail"};
     
     SearchControls ctls = new SearchControls();
     ctls.setReturningAttributes(attrIDs);
     
     // 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("ou=People",
       filter, ctls);
  
     while (enum.hasMore()) {
         SearchResult entry = (SearchResult)enum.next();
         process(entry);
     }
 } catch (NamingException e) {
 }
