Searching through LDAP

Friends, here is an example Java Code for searching through LDAP directory. Seems to be useful, if you are going to search in our Lotus Domino directory....

import java.util.Hashtable;

import javax.naming.Context;
import javax.naming.NamingEnumeration;
import javax.naming.directory.Attribute;
import javax.naming.directory.Attributes;
import javax.naming.directory.DirContext;
import javax.naming.directory.InitialDirContext;
import javax.naming.directory.SearchControls;
import javax.naming.directory.SearchResult;

public class LdapSearch {
  public static void main(String[] args) throws Exception {
    Hashtable env = new Hashtable();

    String sp = "com.sun.jndi.ldap.LdapCtxFactory";
    env.put(Context.INITIAL_CONTEXT_FACTORY, sp);

    String ldapUrl = "ldap://localhost:389/dc=yourName, dc=com";
    env.put(Context.PROVIDER_URL, ldapUrl);

    DirContext dctx = new InitialDirContext(env);

    String base = "ou=People";

    SearchControls sc = new SearchControls();
    String[] attributeFilter = { "cn", "mail" };
    sc.setReturningAttributes(attributeFilter);
    sc.setSearchScope(SearchControls.SUBTREE_SCOPE);

    String filter = "(&(sn=W*)(l=Criteria*))";

    NamingEnumeration results = dctx.search(base, filter, sc);
    while (results.hasMore()) {
      SearchResult sr = (SearchResult) results.next();
      Attributes attrs = sr.getAttributes();

      Attribute attr = attrs.get("cn");
      System.out.print(attr.get() + ": ");
      attr = attrs.get("mail");
      System.out.println(attr.get());
    }
    dctx.close();
  }
}
