I found the solution. it works for me, if you have better way, feel free to share ....
private String proxy(String url) throws IOException { CredentialsProvider provider = new BasicCredentialsProvider(); UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("USERNAME", "PASSWORD"); provider.setCredentials(AuthScope.ANY, credentials); try (CloseableHttpClient httpClient = HttpClientBuilder.create().setDefaultCredentialsProvider(provider) .build();) { HttpGet request = new HttpGet(url); HttpResponse response = httpClient.execute(request); BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); StringBuffer body = new StringBuffer(); String line = ""; while ((line = rd.readLine()) != null) { body.append(line + System.lineSeparator()); } return body.toString(); } } @Override public void configure() throws Exception { from("jetty:http://0.0.0.0:8080/myapp?matchOnUriPrefix=true ").routeId("webserviceproxyroute") .process(exchange -> { exchange.getOut() .setBody(proxy("http://remotehost/webservice?wsdl")); }).log(LoggingLevel.INFO, "Response \n ${body}"); } I used below code as proxy to download wsdl file from remote webservice, but it does not work. only get html back instead of wsdl file <route> <from uri="servlet:myapp?matchOnUriPrefix=true"/> <to uri="http://realserverhostname:8090/webservice?wsdl&bridgeEndpoint=true&throwExceptionOnFailure=false"/> </route> Ps: Of couse using browser I am able to open http://realserverhostname:8090/webservice?wsdl as wsdl file via camel route It only got something like below <html><body><p>Mocked Interfaces in project </p><ul><li><a href="/xxx?WSDL&interface=xxx">xxx</a></li><li><a href="/xxx?WSDL&interfacexxx">xxx</a></li></ul></p></body></html> Any hints or ideas?
