searching program in LDAP

[Babu Singh]

i am making a program with LDAP to search the name.

  
import java.io.*;
import java.util.Hashtable;
import javax.naming.*;
import javax.naming.directory.*;
import javax.naming.ldap.*;

public class fullname1 {

public static void main(String[] args) {

try {
Hashtable env = new Hashtable();
/*
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.STATE_FACTORIES, "PersonStateFactory");
env.put(Context.OBJECT_FACTORIES, "PersonObjectFactory");
env.put(Context.PROVIDER_URL, "ldap://127.0.0.1:389/"); // SET YOUR SERVER AND STARTING CONTEXT HERE
env.put(Context.SECURITY_PRINCIPAL, "cn=admin, o=myorg"); // SET USER THAT CAN SEARCH AND MODIFY FULL NAME HERE
env.put(Context.SECURITY_CREDENTIALS, "password"); // SET PASSWORD HERE
*/
try
{
env.put(Context.PROVIDER_URL, "ldap://174.129.214.187:389/");    // SET YOUR SERVER AND STARTING CONTEXT HERE
env.put(Context.SECURITY_PRINCIPAL, "ocsr2\\administrator");  // SET USER THAT CAN SEARCH AND MODIFY FULL NAME HERE
env.put(Context.SECURITY_CREDENTIALS, "instant2009");
System.out.println("going from Context");
}
catch(Exception e){System.out.println("URL Exception is---- "+e);}
System.out.println("now going to DirContext");
env.put(LdapContext.CONTROL_FACTORIES, "com.sun.jndi.ldap.ControlFactory");
DirContext ctx = new InitialDirContext(env);


// Specify the search filter to match all users with no full name
String filter = "(&(objectClass=Person) (!(fullName=*)))";
// limit returned attributes to those we care about
String[] attrIDs = {"sn", "givenName", "fullName"};
SearchControls ctls = new SearchControls();
ctls.setReturningAttributes(attrIDs);
// comment out next line to limit to one container otherwise it'll walk down the tree
ctls.setSearchScope(ctls.SUBTREE_SCOPE);

// Search for objects using filter and controls
NamingEnumeration answer = ctx.search("", filter, ctls);

// cycle through result set
while (answer.hasMore()) {
SearchResult sr = (SearchResult)answer.next();
System.out.println(">>>" + sr.getName());
String dn = sr.getName();
Attributes attrs = sr.getAttributes();
String givenName = " ";
String surName = " ";
try {
givenName = attrs.get("givenName").toString();
} catch (Exception err) {
givenName = " ";
}
try {
surName = attrs.get("sn").toString();
} catch (Exception e2) {
surName = " ";
}
// eDir returns "attribute name : attribute value on get method so strip off up to ": "
attrs.put("fullName", givenName.substring(givenName.indexOf(':')+2) + ' ' + surName.substring(surName.indexOf(':')+2));
//attrs.put("fullName", givenName.substring(givenName.indexOf(':… + ' ' + surName.substring(surName.indexOf(':')+2…
ctx.modifyAttributes(sr.getName(), DirContext.REPLACE_ATTRIBUTE, attrs);
}

// Close the context when we're done
ctx.close();
}
catch(NamingException ne) {
System.err.println(ne);
ne.printStackTrace();
}
}
}
  

but i am facing exception.
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file Here:

  NamingEnumeration answer = ctx.search("", filter, ctls);  

please suggest how i resolve this issue. or any other searching program in LDAP

I'm not an expert, but I think that you should provide an URL as first parameter for the search() method (or use an InitialContextFactoryBuilder).
