我已经坚持了一段时间了。我正在尝试访问我使用 HttpClient 和 Tomcat 7 实现的 ContainerServlet。我不断收到错误消息“Restricted(ContainerServlet)”。我添加了基本身份验证并尝试像内置的主机管理器应用程序一样设置它，但没有运气。
我的 HostManagerServlet 以：
public class HostManagerServlet
extends HttpServlet implements ContainerServlet {...
我的 web.xml 包含：
<servlet>
<servlet-name>virtualHostCreator</servlet-name>
<servlet-class>com.eatmyfish.servlets.HostManagerServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>virtualHostCreator</servlet-name>
<url-pattern>/virtualhostcreator/*</url-pattern>
</servlet-mapping>
<security-constraint>
<web-resource-collection>
<web-resource-name>HostManager commands</web-resource-name>
<url-pattern>/virtualhostcreator/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<!-- NOTE: This role is not present in the default users file -->
<role-name>admin-script</role-name>
</auth-constraint>
</security-constraint>
<security-constraint>
<web-resource-collection>
<web-resource-name>HTMLHostManager commands</web-resource-name>
<url-pattern>/virtualhostcreator/*</url-pattern>

<auth-constraint>
<!-- NOTE: This role is not present in the default users file -->
<role-name>admin-gui</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>

<security-role>

</security-role>
<security-role>
<description>
The role that is required to log in to the Host Manager Application text
interface
</description>
<role-name>admin-script</role-name>
</security-role>
我的 tomcat-users.xml 包含：
.
.
.
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="manager-gui"/>
<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat,admin-gui,admin-script,manager-gui"/>

进行 HttpClient 调用的代码（我尝试了几种不同的方法）：
方法一 -
String url = environment.getProperty("baseurl");
url += "virtualhostcreator/createVirualHost?name="+group.getGroupName();
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(url);
httpget.addHeader(BasicScheme.authenticate(
new UsernamePasswordCredentials("tomcat", "tomcat"),
"UTF-8", false));
HttpResponse response = httpclient.execute(httpget);
方法二 -
String url = environment.getProperty("baseurl");
url += "virtualhostcreator/createVirualHost?name="+group.getGroupName();
DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.getCredentialsProvider().setCredentials(
new AuthScope("localhost", 8080),
new UsernamePasswordCredentials("tomcat", "tomcat"));
// Create AuthCache instance
AuthCache authCache = new BasicAuthCache();
// Generate BASIC scheme object and add it to the local
// auth cache
HttpHost targetHost = new HttpHost("localhost", 8080, "http");
BasicScheme basicAuth = new BasicScheme();
authCache.put(targetHost, basicAuth);
// Add AuthCache to the execution context
BasicHttpContext localcontext = new BasicHttpContext();
localcontext.setAttribute("http.auth.auth-cache", authCache);
HttpGet httpget = new HttpGet(url);
HttpResponse response = httpclient.execute(targetHost, httpget,localcontext);
错误的堆栈跟踪：

任何想法我做错了什么？我无法通过 Restricted(ContainerServlet) 错误。
