Class HTMLHostManagerServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.apache.catalina.manager.host.HostManagerServlet
              org.apache.catalina.manager.host.HTMLHostManagerServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig, ContainerServlet

public final class HTMLHostManagerServlet
extends HostManagerServlet

Servlet that enables remote management of the virtual hosts deployed on the server. Normally, this functionality will be protected by a security constraint in the web application deployment descriptor. However, this requirement can be relaxed during testing.

The difference between the HostManagerServlet and this Servlet is that this Servlet prints out a HTML interface which makes it easier to administrate.

However if you use a software that parses the output of HostManagerServlet you won't be able to upgrade to this Servlet since the output are not in the same format as from HostManagerServlet
