Also thanks Julain/Bertand. I now have about the simplest hello world
program working. I suspect as I get further into the project, I will need to
look at the authentication system a lot more thoroughly, but for now I am
happy with just being able to POST and GET data!

public class PopulateRepository {
public static void main(String[] args) throws Exception {
String nodeName = "newNodea";
String userName = "admin";
String password = "admin";

DefaultHttpClient client = new DefaultHttpClient();
client.addRequestInterceptor(new PreemptiveAuthInterceptor(), 0);
client.getCredentialsProvider().setCredentials(new AuthScope("localhost",
8080), new UsernamePasswordCredentials(userName, password));
UrlEncodedFormEntity entity = new
UrlEncodedFormEntity(Arrays.<NameValuePair> asList(new
BasicNameValuePair("param1", "value11"), new BasicNameValuePair("param2",
"valueq")), "UTF-8");
HttpPost action = new HttpPost("http://localhost:8080/" + nodeName);
action.setEntity(entity);
HttpResponse response = client.execute(action);

System.out.println("Status: " + response.getStatusLine().getStatusCode());
}

private static class PreemptiveAuthInterceptor implements
HttpRequestInterceptor {

@Override
public void process(HttpRequest request, HttpContext context) throws
HttpException, IOException {

AuthState authState = (AuthState)
context.getAttribute(ClientContext.TARGET_AUTH_STATE);
CredentialsProvider credsProvider = (CredentialsProvider)
context.getAttribute(ClientContext.CREDS_PROVIDER);
HttpHost targetHost = (HttpHost)
context.getAttribute(ExecutionContext.HTTP_TARGET_HOST);

// If not auth scheme has been initialized yet
if (authState.getAuthScheme() == null) {
AuthScope authScope = new AuthScope(targetHost.getHostName(),
targetHost.getPort());

// Obtain credentials matching the target host
Credentials creds = credsProvider.getCredentials(authScope);

// If found, generate BasicScheme preemptively
if (creds != null) {
authState.setAuthScheme(new BasicScheme());
authState.setCredentials(creds);
}
}
}
}
}
