Rest Template

[nagarjun.kovi@gmail.com]

Here in this code i need to make a post rest call to the tomcat server . I need to send username and password along with the post call.

exception i am getting is:

2012-06-05 21:15:34,338 DEBUG [org.springframework.web.client.RestTemplate] - <Created POST request for "http://localhost:8080/cube/rest/saiku/session">

I have tried with different httpmessage converters.

jdk 1.7
tomcat 7.0.23
versions

<spring.version>3.0.4.RELEASE</spring.version>
<springsecurity.version>3.0.3.RELEASE</springsecurity.version>
<resteasy.version>2.0.1.GA</resteasy.version>

this is the java code.
@Component( "articleClient" )
public class ArticleClient
{
protected RestTemplate restTemplate;
@SuppressWarnings("unchecked")
public ResponseEntity<String> getArticle() throws UnsupportedEncodingException {
RestTemplate restTemplate = new RestTemplate();

List<HttpMessageConverter<?>> messageConverters = new ArrayList<HttpMessageConverter<?>>();
messageConverters.add(new FormHttpMessageConverter());
HttpMessageConverter formHttpMessageConverter = new FormHttpMessageConverter();
MappingJacksonHttpMessageConverter jsonConverter = new MappingJacksonHttpMessageConverter();
messageConverters.add(formHttpMessageConverter);
messageConverters.add(jsonConverter);
restTemplate.setMessageConverters(messageConverter s);


String url = "http://localhost:8080/cube/rest/saiku/session";

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_ URLENCODED);

ArrayList<BasicNameValuePair> params= new ArrayList<BasicNameValuePair>();
params.add(new BasicNameValuePair("username", "admin"));
params.add(new BasicNameValuePair("password", "admin"));

HttpEntity req = new HttpEntity(new UrlEncodedFormEntity(params),headers);
ResponseEntity str= restTemplate.postForEntity(url,req, String.class);
//System.out.println(event);
System.out.println( str.getBody() );
return str;
}
}
