Я пытаюсь запустить следующую программу:
package jndi;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.naming.directory.Attributes;
import javax.naming.directory.DirContext;
public class LDAPRead {
public static void main(String[] args) {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://localhost:389/o=jaydeetechnology");
try{
System.out.println("creating initial directory context");
DirContext ctx = (DirContext) new InitialContext(env);
System.out.println("search for john hunt");
Attributes attrs = ctx.getAttributes("cn=John Hunt , ou=JayDeeTechnology");
System.out.println("find the surname and print it");
System.out.println("sn: "+attrs.get("sn").get());
ctx.close();
}catch(NamingException e){
e.printStackTrace();
}
}
}
но я получаю сообщение об ошибке "Отказано в соединении". Может ли кто-нибудь помочь мне, если я что-то упустил?
