I use the HttpClient methods:

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.methods.GetMethod;

like so:

HttpClient client = new HttpClient();
HttpMethod method = new GetMethod("http://www.google.com");
int responseCode = client.executeMethod(method);
if (responseCode != 200) {
    throw new HttpException("HttpMethod Returned Status Code: " + responseCode + " when attempting: " + url);
}
String rtn = StringEscapeUtils.unescapeHtml(method.getResponseBodyAsString());

EDIT: Oops. StringEscapeUtils comes from commons-lang. http://commons.apache.org/lang/api/org/apache/commons/lang/StringEscapeUtils.html
