Is there a way to hide the JBossWeb or Tomcat version in an error page?

Issue

• The default Tomcat error handler displays the version details of the application server. Is there a way to hide this information from end users. It is possible that a remote attacker could use this information to mount further attacks.
• I need to remove the jbossweb version from default error page message. Is there an option to change the version string ?
• We have receive HTTP 401 response. How can we customise this error response? E.g. the response should not contain the jboss version.

• Can you globally in JBoss EAP 6 configure custom error pages for 404, etc? I know that you can do that per application in web.xml,but this means that each application has to have custom valve. This is not satisfaction.

  <error-page>
  <error-code>400</error-code>
  <location>/WEB-INF/errorpage/400.jsp</location>
  </error-page>
