Question

I am currently getting to grips with new HttpClient libraries to come up with a basic class to return the html/css/etc. of requested URL. Using the example taken from here

You can see the example below:

package test;

import org.apache.http.client.ResponseHandler;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicResponseHandler;
import org.apache.http.impl.client.DefaultHttpClient;

public class Test {

    public final static void main(String[] args) throws Exception {

        HttpClient httpclient = new DefaultHttpClient();
        try {
            HttpGet httpget = new HttpGet("http://www.cwjobs.co.uk/");
            System.out.println("executing request " + httpget.getURI());

            // Create a response handler
            ResponseHandler<String> responseHandler = new BasicResponseHandler();
            String responseBody = httpclient.execute(httpget, responseHandler);

            System.out.println(responseBody);
        } finally {
            httpclient.getConnectionManager().shutdown();
        }
    }
}

The issue I am having is that if I was to set the URL I want to request to something like http://www.google.com then it prints out the response I need. However, when I use a URL such as http://www.cwjobs.co.uk (used merely as an example) it freezes on the execute method.

I am fairly new to Java and I understand the basics of HTTP so I would love to know if:
– Although I have used a basic example I have done it wrong by either missing something that needs to be added to access that specific URL
– It is not possible to get the response I want from that specific URL due to environment setup on the Server side.
– Any extra literature or links you can recommend for me to look over outside of the Apache.org site

Thanks,
Mark

You have to set the timeout in DefaultHttpClient for the connection. See: http://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/params/CoreConnectionPNames.html?is-external=true#SO_TIMEOUT
