How to use ProxyServlet

[Martin M]

After many attempts at making dropwizard proxy all i get is status code 502 Bad Gateway:

I have and old jetty project on http://test:80/

and a new dropwizard project on http://dropwizard:8085/

I want the old project to be proxied on  http://dropwizard:8085/old/

I have tried:

        ProxyClassic proxyClassic = new ProxyClassic("http://test:80/", "/old");

        environment.servlets().addServlet("ProxyClassic", proxyClassic).addMapping("/old/*");

public class ProxyClassic extends ProxyServlet {

    public ProxyClassic(String proxyTo, String proxyPrefix) {

        delegate._proxyTo = proxyTo;

        delegate._prefix = proxyPrefix;

    }

    

    private final TransparentDelegate delegate = new TransparentDelegate(this);

    @Override

    public void init(ServletConfig config) throws ServletException {

        super.init(config);

        delegate.init(config);

    }

    protected static class TransparentDelegate

    {

        private final ProxyServlet proxyServlet;

        private String _proxyTo;

        private String _prefix;

        protected TransparentDelegate(ProxyServlet proxyServlet)

        {

            this.proxyServlet = proxyServlet;

        }

        protected void init(ServletConfig config) throws ServletException

        {

            // Adjust prefix value to account for context path

            String contextPath = config.getServletContext().getContextPath();

            _prefix = _prefix == null ? contextPath : (contextPath + _prefix);

        }

    }

        <dependency>

            <groupId>org.eclipse.jetty</groupId>

            <artifactId>jetty-proxy</artifactId>

            <version>9.3.9.v20160517</version>

            <scope>compile</scope>

        </dependency>

I am using dropwizard 1.0.0

Any suggestions how i can do this?

You can use jetty Transparent servlet (the same as your ProxyClassic):

final ServletRegistration.Dynamic proxy = environment.servlets().addServlet("proxy", ProxyServlet.Transparent.class);
proxy.setInitParameter("proxyTo", "http://test:80/");
proxy.setInitParameter("prefix", "/old");
proxy.addMapping("/old/*");
