Java HttpClient to connect to RAM server

Hi,
I'm looking for a simple Java http client to be able to connect to a RAM server in order to read asset via REST API (OSLC). Does anyone has a code snippet to share to connect to a RAM server using the class org.apache.commons.httpclient.HttpClient?
I'm trying to define a login method in a subclass of HttpClient such as

GetMethod get = new GetMethod("http://localhost:13080/ram/secure/loginProxy.faces");



int responseCode = executeMethod(get);



PostMethod post = new PostMethod("http://localhost:13080/ram");

		

NameValuePair[] nvps = new NameValuePair[2];

nvps[0] = new NameValuePair("j_username", user);

nvps[1] = new NameValuePair("j_password", password);

post.addParameters(nvps);

responseCode = executeMethod(post);

That would be greatly appreciated...
Thanks in advance for sharing.

HttpClient httpClient = new HttpClient();

//Set the userid and password

Credentials credentials = new UsernamePasswordCredentials(USER, PASSWORD);

httpClient.getState().setCredentials(AuthScope.ANY, credentials);



//Perform the HTTP call

GetMethod getAssetDetailsMethod = new GetMethod("http://localhost:13080/ram.ws/oslc/assets/GUID/version");

int responseCode = executeMethod(getAssetDetailsMethod);
