This is TOMCAT page, click on the left of the status required to enter a user name and password, I want to use Java code to automatically fill in the user name and password. I do not know how to do this , with a httpClient, seemingly not, what other http tool can achieve this function?
------ Solution ---------------------------------------- ----
ajax. . . . . .
------ Solution ---------------------------------------- ----
configuration file needs to be configured . tomcat-users.xml

  import java.io.IOException;
  
  import org.apache.commons.httpclient.DefaultHttpMethodRetryHandler;
  import org.apache.commons.httpclient.HttpClient;
  import org.apache.commons.httpclient.HttpException;
  import org.apache.commons.httpclient.HttpStatus;
  import org.apache.commons.httpclient.UsernamePasswordCredentials;
  import org.apache.commons.httpclient.auth.AuthScope;
  import org.apache.commons.httpclient.methods.GetMethod;
  import org.apache.commons.httpclient.params.HttpMethodParams;
  
  public class AutoLoginTomcat {
  
  	/**
  	 * @param args
  	 */
  	public static void main(String[] args) {
  		HttpClient httpClient = new HttpClient();
  
  		httpClient.getState().setCredentials(
  				new AuthScope("127.0.0.1", 8080, null),
  				new UsernamePasswordCredentials("admin", "admin"));
  		httpClient.getParams().setAuthenticationPreemptive(true);
  
  		GetMethod getMethod = new GetMethod(
  				"http://127.0.0.1:8080/manager/status?XML=true");
  		getMethod.setDoAuthentication(true);
  		getMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
  				new DefaultHttpMethodRetryHandler());
  		try {
  			int statusCode = httpClient.executeMethod(getMethod);
  			if (statusCode != HttpStatus.SC_OK) {
  				System.err.println("Method failed: "
  						+ getMethod.getStatusLine());
  			}
  			byte[] responseBody = getMethod.getResponseBody();
  			System.out.println(new String(responseBody));
  		} catch (HttpException e) {
  			System.out.println("Please check your provided http address!");
  			e.printStackTrace();
  		} catch (IOException e) {
  			e.printStackTrace();
  		} finally {
  			getMethod.releaseConnection();
  		}
  	}
  
  }

thanks ! jar package found , and now has an independent httpclient out.

In this page , http://hc.apache.org/downloads.cgi

found
Older releases
Old releases are available from the archives.

is to find the old version

then commons-httpclient /

then http://archive.apache.org/dist/httpcomponents/commons-httpclient/binary/

download jar package, this also depends on the other two httpclient jar it.
This should be very good looking.
