Very helpful info.

Nice to see you got it working with SSL.
Btw, I just blogged about accessing SSL configured resources using RestTemplate here.

You may want to look at the MappingJacksonHttpMessageConverter which supports “application/json”.

Once more question: I format the return from Rest Servie as a json. In spring 3M4, there is no coverter for Json, I saw you using the FormHttpMessageConverter. How would you handle when stuff return are in JSON format

again greatly appreciated

No problem.

You may want to look at the Jersey client sample used to access a secured resource. This would give you an idea on how to setup TrustManager and KeyManager on the client.

I did receive your email. I did not had a chance to respond to your email yet.

You may want to look at the SSL Guide for Commons HTTP Client. You need to configure the HttpClient from RestTemplate with an SSLSocketFactory.

If you got any ideas, please help.

Yes, you would require commons-httpclient-3.1.jar for creating HTTP requests with basic auth.

The following code would set the credentials for your requests (refer to the TwitterClient constructor) :
CommonsClientHttpRequestFactory factory = (CommonsClientHttpRequestFactory) restTemplate.getRequestFactory();
HttpClient client = factory.getHttpClient();
client.getState().setCredentials(AuthScope.ANY, credentials);

You need to inject a ‘httpClientFactory’ to the RestTemplate, in this case the client factory is backed by Commons HTTP Client.

Let me know if this helps.

1. Do I need to have the commons-httpclient.jar from org.apache.commons.httpclient in order to pass in the user/password?

snippet from my applicationcontext.xml

class=”…RestTemplate”>

In my service
public class MyService implements MyServiceI {
private RestTemplate restTemplate;

public String getData(String url,String id) {

return getRestTemplate.getForObject(url,String.class,id);
—-> so what do I do here in order to pass in the authentication info.
}

getter/setter for RESTtemplate
}

Very much thank you.

The ClientHttpRequestFactory allows users to plugin either standard J2SE based facility for creating HTTP requests or using CommonsClient APIs. The SimpleClientHttpRequestFactory is very primitive when compared to the comprehensive CommonsClient backed CommonsClientHttpRequestFactory. If you need to perform authentication with your Restful resources, then you may want to use RestTemplate backed by CommonsClient.

Please refer to the Spring configuration in the blog entry which does the magic of wiring HttpClient with RestTemplate using the ClientHttpRequestFactory. The credentials are configured as a bean in Spring config.

Let me know if you have any specific questions.
