I'm having trouble getting TomEE to forward my request to a different webapp from the same ear file.
I updated the context.xml enabled crossContext:
<Context antiResourceLocking="false" privileged="true" crossContext="true">
<!--
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="172.17.0.1" />
-->
<Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>
The webapp that I'm forwarding from is a simple Servlet:
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
try {
RequestDispatcher dispatcher;
dispatcher = getServletContext().getContext("/web2").getRequestDispatcher("/webapp2/hello");
dispatcher.forward(req, resp);
} catch (Exception e) {
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw, true);
e.printStackTrace(pw);
resp.sendError(HttpServletResponse.SC_BAD_REQUEST, sw.toString());
}
}
The webapp that it should be forwarded to is a Rest Resource that looks like this:
package local.gerb;
import javax.ws.rs.*;
@Path("webapp2")
public class HelloResource {
@GET
@Path("hello")
@Produces("text/plain")
public String getMessage() {
return "Rest Never Sleeps";
}
}
I did verify that webapps2 is working by curling the particular endpoint.
However, when I curl the webapp1 which should forward to webapp2 I get a 404. What is strange, is if I convert the Rest Resource to a plain servlet the forwarding works fine.
If you want to see the code I have it pushed to github: https://github.com/jstralko/tomee-fwd
I have a ReadMe explaining how to build and run this application. It runs in a docker container so everything is self-contained and super easy to build and run.

I decided to debug the TomEE and found this code that was causing issues in CXFJAXRSFilter.java:
@Override
public void doFilter(final ServletRequest request, final ServletResponse response, final FilterChain chain) throws IOException, ServletException {
if (!HttpServletRequest.class.isInstance(request)) {
chain.doFilter(request, response);
return;
}
final HttpServletRequest httpServletRequest = HttpServletRequest.class.cast(request);
final HttpServletResponse httpServletResponse = HttpServletResponse.class.cast(response);
if (CxfRsHttpListener.TRY_STATIC_RESOURCES) { // else 100% JAXRS
if (servletMappingIsUnderRestPath(httpServletRequest)) {
chain.doFilter(request, response);
return;
}
final InputStream staticContent = delegate.findStaticContent(httpServletRequest, welcomeFiles);
if (staticContent != null) {
chain.doFilter(request, response);
return;
}
}
try {
delegate.doInvoke(
new ServletRequestAdapter(httpServletRequest, httpServletResponse, request.getServletContext()),
new ServletResponseAdapter(httpServletResponse));
} catch (final Exception e) {
throw new ServletException("Error processing webservice request", e);
}
}
The line that was causing issues:
if (CxfRsHttpListener.TRY_STATIC_RESOURCES) { // else 100% JAXRS
So I found the definition of TRY_STATIC_RESOURCES
public static final boolean TRY_STATIC_RESOURCES = "true".equalsIgnoreCase(SystemInstance.get().getProperty("openejb.jaxrs.static-first", "true"));
So I updated the system.property of openejb.jaxrs.static-first to false and it worked.
$> curl 'http://localhost:8080/web1/webapp1?op=foo'
Hello From Webapp2 Rest Resource%
I pushed up my changes to my github repo for those of us that are playing along.
