I have been stuck on this one for a while. I am trying to access the ContainerServlet I implemented using HttpClient with Tomcat 7. I keep getting the error message "Restricted(ContainerServlet)". I have added Basic Authentication and tried to set it up just like the built in Host-Manager application with no luck.
My HostManagerServlet starts with:
public class HostManagerServlet
extends HttpServlet implements ContainerServlet {...
My web.xml contains:
<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>
</web-resource-collection>
<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>
</login-config>
<security-role>
<description>

</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>
My tomcat-users.xml contains:
.
.
.
<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"/>
.
.
.
The code that makes the HttpClient call (I've tried a few different approaches):
Approach One -
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);
Approach Two -
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);
The error's stacktrace:

Any ideas what I am doing wrong? I cannot get past the Restricted(ContainerServlet) error.
I had a similar problem in Tomcat 7 and was able to work around it by editing the top-level element in ./conf/context.xml
to look like
<Context privileged="true">
What I can't figure out is how Tomcat's own manager servlets are able to load without this configuration. Anybody have any clues?
I found the answer. I needed to set privileged=true in the context of the host inside server.xml
