Jersey Client + set proxy

Question

Hi I've a jersey client which i use to upload a file. I tried using it locally and everything works fine. But in production environment i've to set proxy. I browsed thru few pages but could not get exact solution. Can someone pls help me with this?

here is my client code:

File file = new File("e:\\test.zip");
FormDataMultiPart part = new FormDataMultiPart();

    part.bodyPart(new FileDataBodyPart("file", file, MediaType.APPLICATION_OCTET_STREAM_TYPE));

    WebResource resource = null;

    if(proxy.equals("yes")){
    //How do i configure client in this case?

    }else{
            //this uses system proxy i guess
        resource = Client.create().resource(url);   
    }

    String response = (String)resource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(String.class, part);

    System.out.println(response);

There is an easier approach, if you want to avoid more libraries in legacy projects and there is no need for Proxy Authentication:

First you need a class which implements HttpURLConnectionFactory:

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.net.URL;

import com.sun.jersey.client.urlconnection.HttpURLConnectionFactory;


public class ConnectionFactory implements HttpURLConnectionFactory {

    Proxy proxy;

    private void initializeProxy() {
        proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("myproxy.com", 3128));
    }

    public HttpURLConnection getHttpURLConnection(URL url) throws IOException {
        initializeProxy();
        return (HttpURLConnection) url.openConnection(proxy);
    }
}

Second is to instantiate an com.sun.jersey.client.urlconnection.URLConnectionHandler

URLConnectionClientHandler ch  = new URLConnectionClientHandler(new ConnectionFactory());

and third is to use the Client Constructor instead of Client.create:

Client client = new Client(ch);

Of course you can customize the initializing of the Proxy in the ConnectionFactory.
