            Thanks for your support. But its not working

             

            My tomcat-users.xml file

             

             

            <tomcat-users>
        <role rolename="manager"/>
        <user username="tomcat" password="s3cret" roles="manager" />
</tomcat-users>

             

            My code is :

             

            import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
import org.apache.commons.httpclient.params.HttpMethodParams;

import java.io.*;

public class HttpClientTutorial
{

    private static String url = "http://localhost:8080/manager/html/stop?path=/jsfproject";

    public static void main(String[] args)
    {
        // Create an instance of HttpClient.
        HttpClient client = new HttpClient();

        // Create a method instance.
        GetMethod method = new GetMethod(url);

        // Provide custom retry handler is necessary
        method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
                new DefaultHttpMethodRetryHandler(3, false));

        try
        {
            // Execute the method.
            int statusCode = client.executeMethod(method);

            if (statusCode != HttpStatus.SC_OK)
            {
                System.err.println("Method failed: " + method.getStatusLine());
            }

            // Read the response body.
            byte[] responseBody = method.getResponseBody();

            // Deal with the response.
            // Use caution: ensure correct character encoding and is not binary data
            System.out.println(new String(responseBody));
        }
        catch (HttpException e)
        {
            System.err.println("Fatal protocol violation: " + e.getMessage());
            e.printStackTrace();
        }
        catch (IOException e)
        {
            System.err.println("Fatal transport error: " + e.getMessage());
            e.printStackTrace();
        }
        finally
        {
            // Release the connection.
            method.releaseConnection();
        }
    }
}

             

            But not stopped application. I got the follwing message in my console

              it seems that tomcat container itself doesn't allow external application to perform stop/undeploy operations.
