Forwarding from root context with embedded tomcat

I'm using CAS 5.2.5 with the embedded Tomcat app server, and I would like to have the root context redirect to /cas/. If I were using Tomcat separately, I would place this JSP file in $CATALINA_HOME/webapps/ROOT, but that solution doesn't seem to apply here. Is there some way to build or configure the WAR file to do this?

<html>
<head>
<title>Welcome to CAS</title>
</head>
<body>
    <p>Redirecting to SSO</p>
    <%
        response.setStatus(301);
        response.setHeader("Location", "/cas/login");
    %>
</body>
</html>

Since CAS is ultimately a Spring Boot application, you can probably setup additional dispatcher servlets to field requests targeting paths outside the default context path "/cas". But I don't think it's worth pursuing because of the amount of customization to the default war-overlay-template setup will make your CAS hard to maintain in the future. You are much better off not using the embedded Tomcat, but deploy CAS to Tomcat and continue using your jsp file solution. Alternatively have a fronting web server do the redirect for you.

You could override Boot’s `server.context-path` property like so:

java -jar /path/to/your/cas.war --server.context-path=/

Oh, I see.. you want the root context to do the redirect to /cas… Never mind then ;-)

But wouldn't that change all the CAS endpoints from /cas/xyz to /xyz?

Yep, it would. As I noted in my other email - never mind ;-)
