How to forward all kind of request from ROOT to other web app context with Tomcat

I need to forward all kind of request from the ROOT, i.e http://localhost:8080/ to http://localhost:8080/myRoot

Is it possible, do I need to create a redirect servlet? However, I think tomcat can be configured to behave that way?

What I did is to use UrlRewriteFilter

Deployed the filter into the ROOT and modified the urlrewrite.xml like this:

<rule>
    <from>^/$</from>
    <to type="redirect">%{context-path}/myRoot</to>
</rule>

And now it works.

An easy way would be to create a filter something like this

@WebFilter("/*")
public class RedirectFilter implements Filter {

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) req;
        HttpServletResponse response = (HttpServletResponse) res;

        String uri = request.getRequestURI();
        String query = request.getQueryString();

        if (query != null) {
            uri = uri + "?" + query;
        }

        response.setStatus(301);
        response.setHeader("Location", "/myRoot" + uri);
        // Can also use response.sendRedirect(), but this does 302 by default.
    }

    // ...
}

and put it in Tomcat/webapps/ROOT/WEB-INF/classes/com/example/RedirectFilter.class.

If you're still using Tomcat 6.0 or older, then remove @WebFilter annotation and create the web.xml accordingly.
