java: apache HttpClient > how to disable retry

Question

I\'m using Apache Httpclient for Ajax-calls on a website. In some cases requests to external webservice fail, often with:

I/O exception (java.net.ConnectException) caug

OK. There is issue in the Documentation. Also there has been change in API and methods. So if you want to use DefaultHttpRequestRetryHandler , here are the ways to do that,

DefaultHttpClient httpClient = new DefaultHttpClient();
DefaultHttpRequestRetryHandler retryHandler = new DefaultHttpRequestRetryHandler(0, false);
httpClient.setHttpRequestRetryHandler(retryHandler);

or

HttpClient httpClient = new DefaultHttpClient();
DefaultHttpRequestRetryHandler retryHandler = new DefaultHttpRequestRetryHandler(0, false);
((AbstractHttpClient)httpClient).setHttpRequestRetryHandler(retryHandler);

In first one, we use concrete DefaultHttpClient (which is a subclass of AbstractHttpClient and so has the setHttpRequestRetryHandler() method.)

In second one, we are programming to the HttpClient interface (which sadly doesn't expose that method, and this is weird !! ehh), so we have to do that nasty cast.
