setup httpclient proxy to access REST url on EC2

I have an EC2 imaging running and hosting a REST service accessible from Url. The following is what I did 1) ssh -i D port user@ec2-host 2) setup proxy in the firefox web browser and type in the url http://ec2-host:port/demo/workflow/lists/demo_workflow

It works fine.

Now I need to send the GET method using Java program, below is my code:

    HttpClient client = new HttpClient();
    HttpMethod method = new GetMethod("http://ec2-host:port/demo/workflow/lists/demo_workflow");
    HostConfiguration config = client.getHostConfiguration();
    config.setProxy(proxyHost, port);
    client.setHostConfiguration(config);

    try {
          client.executeMethod(method);
          if (method.getStatusCode() == HttpStatus.SC_OK) {
             String response = method.getResponseBodyAsString();
             System.out.println("Response = " + response);
          }
    } catch (IOException e) {
          e.printStackTrace();
    } finally {
          method.releaseConnection();
    }

But now I run into exceptions below. Any tips? Thanks a lot!
