How to connect with Java into Active Directory

I am using Weblogic, Ejb3.0. Java 1.6

I need to access Active Directory via Java code.
I read about several ways (Kerberos, LDAP)

Anyone could advice me on comfortable way of doing so? where could I have some full code examples,

Here is a simple code that authenticate and make an LDAP search usin JNDI on a W2K3 :

class TestAD
  static DirContext ldapContext;
  public static void main (String[] args) throws NamingException
      System.out.println("D├ębut du test Active Directory");

      Hashtable<String, String> ldapEnv = new Hashtable<String, String>(11);
      ldapEnv.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
      //ldapEnv.put(Context.PROVIDER_URL,  "ldap://societe.fr:389");
      ldapEnv.put(Context.PROVIDER_URL,  "ldap://dom.fr:389");
      ldapEnv.put(Context.SECURITY_AUTHENTICATION, "simple");
      //ldapEnv.put(Context.SECURITY_PRINCIPAL, "cn=administrateur,cn=users,dc=societe,dc=fr");
      ldapEnv.put(Context.SECURITY_PRINCIPAL, "cn=jean paul blanc,ou=MonOu,dc=dom,dc=fr");
      ldapEnv.put(Context.SECURITY_CREDENTIALS, "pwd");
      //ldapEnv.put(Context.SECURITY_PROTOCOL, "ssl");
      //ldapEnv.put(Context.SECURITY_PROTOCOL, "simple");
      ldapContext = new InitialDirContext(ldapEnv);

      // Create the search controls         
      SearchControls searchCtls = new SearchControls();

      //Specify the attributes to return
      String returnedAtts[]={"sn","givenName", "samAccountName"};

      //Specify the search scope

      //specify the LDAP search filter
      String searchFilter = "(&(objectClass=user))";

      //Specify the Base for the search
      String searchBase = "dc=dom,dc=fr";
      //initialize counter to total the results
      int totalResults = 0;

      // Search for objects using the filter
      NamingEnumeration<SearchResult> answer = ldapContext.search(searchBase, searchFilter, searchCtls);

      //Loop through the search results
      while (answer.hasMoreElements())
        SearchResult sr = (SearchResult)answer.next();


        System.out.println(">>>" + sr.getName());
        Attributes attrs = sr.getAttributes();
        System.out.println(">>>>>>" + attrs.get("samAccountName"));

      System.out.println("Total results: " + totalResults);
    catch (Exception e)
      System.out.println(" Search error: " + e);
