How to import libraries?

Question

Hi,
I am attempting to use the Jakarta Commons HttpClient library in my program.
I have set the CLASSPATH variable in my System Variables "Temp" and "Tmp" to D:\Documents and Settings\nilesh.thakur\Desktop\JAVA\httpclient\httpcomponents-client-4.0.1\lib\httpclient.jar;D:\Documents and Settings\nilesh.thakur\Desktop\JAVA\httpclient\httpcomponents-client-4.0.1\lib\httpmime.jar;D:\product\10.1.3.1\OracleAS_1\MOBILE\Sdk\bin\OLITE40.JAR;D:\Documents and Settings\nilesh.thakur\Desktop\JAVA\Apache\junit-4.8.1.jar;D:\Documents and Settings\nilesh.thakur\Desktop\JAVA\Apache\Logining\commons-logging-1.1.1\commons-logging-1.1.1.jar;
But unfortunately when I compile the .java file I get the following errors :
HttpClientTutorial.java:1: package org.apache.commons.httpclient does not exist
import org.apache.commons.httpclient.*;
Is there a specific folder structure to place the files that I have to follow to get this thing working ?
Is there anything else that one need to do apart from Classpath Setup ?
Is this the right way to set the classpath?

import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
import org.apache.commons.httpclient.params.HttpMethodParams;
import java.io.*;
public class HttpClientTutorial {
  private static String url = "http://www.apache.org/";
  public static void main(String[] args) {
    // Create an instance of HttpClient.
    HttpClient client = new HttpClient();
    // Create a method instance.
    GetMethod method = new GetMethod(url);
    // Provide custom retry handler is necessary
    method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
              new DefaultHttpMethodRetryHandler(3, false));
    try {
      // Execute the method.
      int statusCode = client.executeMethod(method);
      if (statusCode != HttpStatus.SC_OK) {
        System.err.println("Method failed: " + method.getStatusLine());
      // Read the response body.
      byte[] responseBody = method.getResponseBody();
      // Deal with the response.
      // Use caution: ensure correct character encoding and is not binary data
      System.out.println(new String(responseBody));
    } catch (HttpException e) {
      System.err.println("Fatal protocol violation: " + e.getMessage());
      e.printStackTrace();
    } catch (IOException e) {
      System.err.println("Fatal transport error: " + e.getMessage());
      e.printStackTrace();
    } finally {
      // Release the connection.
      method.releaseConnection();
}
