Re: [jetty-users] Single page application routing 
If somebody going to google for the same issue, this is how i solved mine.

ErrorHandler.java
-------------------------------------------------------------------

package com.myproject;

import com.myproject.logger.LoggerFactory;
import org.apache.log4j.Logger;
import org.eclipse.jetty.server.Request;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.Writer;

public class ErrorHandler extends org.eclipse.jetty.server.handler.ErrorHandler
{

	private static Logger logger = LoggerFactory.getLogger();
	private boolean _fistRequest = true;

	@Override
	public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response) throws IOException
	{
		// On 404 page we need to show index.html and let JS router do the work, otherwise show error page
		String redirectRoute = "/index.html";
		if ((response.getStatus() == HttpServletResponse.SC_NOT_FOUND) && _fistRequest) {
			RequestDispatcher dispatcher = request.getRequestDispatcher(redirectRoute);
			if (dispatcher != null) {
				try {
					// reset response
					response.reset();
					// On second 404 request we need to show original 404 page, otherwise will be redirect loop
					_fistRequest = false;
					dispatcher.forward(request, response);
				} catch (ServletException e) {
					super.handle(target, baseRequest, request, response);
				}
			}
		} else if ((response.getStatus() == HttpServletResponse.SC_NOT_FOUND) && ! _fistRequest) {
			logger.error("Can not find internal redirect route " + redirectRoute + " on 404 error. Will show system 404 page");
		} else {
			super.handle(target, baseRequest, request, response);
		}
	}

	@Override
	protected void writeErrorPageBody(HttpServletRequest request, Writer writer, int code, String message, boolean showStacks) throws IOException
	{
		writeErrorPageMessage(request, writer, code, message, request.getRequestURI());
	}

	@Override
	protected void writeErrorPageMessage(HttpServletRequest request, Writer writer, int code, String message, String uri)
		throws IOException
	{
		String statusMessage = Integer.toString(code) + " " + message;
		logger.error("Problem accessing " + uri + ". " + statusMessage);
		writer.write(statusMessage);
	}
}
------------------------------------------------------------------------------------------

Add error handler in Launcher.java
------------------------------------------------------------------------------------------
WebAppContext context = new WebAppContext("webapp", "/");
context.addServlet(new ServletHolder(new DefaultServlet()), "/*");

// Setting custom error handler. Which also acts as URL rewriter in some way.
// On 404 page we need to show index.html and let JS router do the work
context.setErrorHandler(new ErrorHandler());
