Tomcat 7 Beschränkt (ContainerServlet) Fehler

Habe ich fest auf dieser einen für eine Weile. Ich bin versuchen, auf den ContainerServlet ich umgesetzt mit HttpClient mit Tomcat 7. Ich erhalte die Fehlermeldung "Eingeschränkte(ContainerServlet)". Ich habe die Standardauthentifizierung und versuchte, um es einzurichten, ebenso wie die eingebaute Host-Manager-Anwendung mit kein Glück.

Meine HostManagerServlet beginnt mit:

public class HostManagerServlet
extends HttpServlet implements ContainerServlet {...

Meine web.xml enthält:

<servlet>
            <servlet-name>virtualHostCreator</servlet-name>
            <servlet-class>com.eatmyfish.servlets.HostManagerServlet</servlet-class>
          </servlet>
          <servlet-mapping>
            <servlet-name>virtualHostCreator</servlet-name>

Meine tomcat-users.xml enthält:

.
.
.
<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"/>
.
.
.

Den code, der macht die HttpClient-call (ich habe versucht ein paar verschiedene Ansätze):

Ansatz Ein -

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);

Ansatz Der Zwei -

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);

Den Fehler den stacktrace:

Irgendwelche Ideen was ich falsch mache? Ich Schaffe es nicht, Vergangenheit, die Eingeschränkte(ContainerServlet) Fehler.
