Trouble compiling jndi examples in Java Studio

Question

I am having difficulty compiling the jndi example below.
I included the errors below the code.
Any ideas?
import javax.naming.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.naming.directory.*;
import java.util.Hashtable;
public class lookup {
/** Creates a new instance of lookup */
public lookup() {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.RefFSContextFactory");
Context ctx = new InitialContext(env);
methodist/pacs/ldap/lookup.java [26:1] <identifier> expected
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.RefFSContextFactory");
^
methodist/pacs/ldap/lookup.java [26:1] package env does not exist
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.RefFSContextFactory");
^
2 errors
Errors compiling lookup.

I learn a lesson about not expecting samples file to
be fully functional.That's true.
