Hi

using apache HttpClinet i have to connect to two different URLs based on conditions.

we have given two urls URL1 and URl2.

initially i have to connect to URL1 .if it fails due to communication errors retry for 3 times,then also it failed Now connect to URL2 and repeat the same process.finally if URL2 also fails.read from database.

here is my code.

how can i achieve it.please help me.

package one; import org.apache.commons.httpclient.; import org.apache.commons.httpclient.HttpStatus; import org.apache.commons.httpclient.methods.; import org.apache.commons.httpclient.params.HttpMethodParams;

import java.io.*;

public class MyHttpClient {

private static String url = "https://URL1"; private static String url2 = "https://URL2";

public static void main(String[] args) {

// Create an instance of HttpClient.
HttpClient client = new HttpClient();
 HttpClient client2= new HttpClient();

// Create a method instance.
PostMethod method = new PostMethod(url);

// Provide custom retry handler is necessary
method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, 
        new DefaultHttpMethodRetryHandler(3, false));


 PostMethod method2 = new PostMethod(url2);


// Provide custom retry handler is necessary
method2.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());
  }
 if (statusCode == HttpStatus.SC_OK) {
    switch (statusCode) {
        case 200: // HTTP_OK
                  {
                        // 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));
                  }
        case 504: //HTTP_GATEWAY_TIMEOUT
                  {
                   //connection = _sendPending();
                  break;
                  }
        default: //OTHER HTTP_SERVER ERRORS
                  {
                    System.out.println ("Invalid code:"+statusCode);
                    break;

                  }
           }//switch
         }

          int statusCode2 = client2.executeMethod(method2);

  if (statusCode2 != HttpStatus.SC_OK) {
    System.err.println("Method failed: " + method2.getStatusLine());
  }

    switch (statusCode2) {
        case 200: // HTTP_OK
                  {
                        // Read the response body.
                        byte[] responseBody2 = method2.getResponseBody();

                           // Deal with the response.
                           // Use caution: ensure correct character encoding and is not binary data
                            System.out.println(new String(responseBody2));
                  }
        case 504: //HTTP_GATEWAY_TIMEOUT
                  {
                   //connection = _sendPending();
                  break;
                  }
        default: //OTHER HTTP_SERVER ERRORS
                  {
                    System.out.println ("Invalid code2:"+statusCode2);
                    break;

                  }
           }

           System.out.println(".........");



} 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();
}  

} }
