Getting the attributes of an object by using a URL

Question

Hi,
Here is my problem. I want to access to the attributes of an object stored in an LDAP. I know this object when I receive this kind of url:
ldap://163.187.83.145:389/ou=People,dc=slb,dc=com,uid=TOTO;
How can I get the attributes of the uid without changing the code below. If I set the context_provider with this url, I am pointing on the right object but my problem is to get its attributes.
Does anyone know how to do?
Here is an example of my code:
String ldap_URL = ldap://163.187.83.145:389/ou=People,dc=slb,dc=com,uid=TOTO;
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, ldap_URL);

Hello !!
You can very well carry on with your code , to get the attributes you can have a look at this code snippet :
import java.io.*;
import java.util.Hashtable;
import javax.naming.*;
import javax.naming.directory.*;
class GetAttr {
     public static void main(String args[]) {
          Hashtable env = new Hashtable();
          String attname=null;
String ldap_URL="ldap://163.187.83.145:389/ou=People,dc=slb,dc=com,uid=TOTO";
          env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
          env.put(Context.PROVIDER_URL, ldap_url);
          try {
               DirContext ctx = new InitialDirContext(env);
               String[] strAttrID={"objectClass","cn","userPassword"};
               Attributes attrs = ctx.getAttributes("",strAttrID);
               for (
                    NamingEnumeration ae = attrs.getAll();
               ae.hasMore();
               Attribute attr = (Attribute)ae.next();
               System.out.println("\n" + attr.getID());
               for (
                         NamingEnumeration e = attr.getAll();
                         e.hasMore();
                         System.out.print(" : " + e.next() +"\t")
          catch (NamingException ne) {
               ne.printStackTrace();
1.See this line ctx.getAttributes("",strAttrID)....this means that in the URL itself you have given JNDI the complete reference or key to locate the object. For eg: if uid=TOTO was not present in your URL , you could have done ctx.getAttributes("uid=TOTO",strAttrID).
2.This will print only the 3 attributes I have specified(objectclass,cn,password).You can add your own according to the attributes u have in your LDAP directory (see in LDIF.txt or <some-name>.ldif)
Hope this helps
