Permission denied error in app engine code

I am getting the below error in the line 5 while executing the app engine code in localhost and in cloud.

1   HttpClient client = new HttpClient();
2       GetMethod getMethod =new GetMethod(url);
3       client.getHttpConnectionManager().getParams()
4       .setConnectionTimeout(1000);
5       int response = client.executeMethod(getMethod);

I am seeing this error while running the job in localhost and in app engine.

Please find the error logs below:
