Wildfly URI encoding (again..) ------------------------------ Key: WFLY-3467 URL: https://issues.jboss.org/browse/WFLY-3467 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 8.1.0.Final Environment: Linux CentOS Reporter: Bob Slydell Assignee: Stuart Douglas I have a very simple Servlet @WebServlet("/HelloServlet") public class HelloServlet extends HttpServlet with a doGet method that prints and returns the "foo" parameter: protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html;charset=UTF-8"); PrintWriter out = response.getWriter(); String foo = request.getParameter("foo"); out.println("Hello " + foo); System.out.println("Hello " + foo); out.close(); } When running jboss 7.1.1.Final this works fine. I can test with a simple curl script: curl http://127.0.0.1:8080/hello-1/HelloServlet?foo=b$'\xc3\xa5'r where $'\xc3\xa5' is "aring" or "a with a ring", (å). I know the console can handle this, because echo $'\xc3\xa5' gives: [slydell@localhost hello]$ echo $'\xc3\xa5' å [slydell@localhost hello]$ If I run the curl script on jboss 7.1.1.Final I get: [slydell@localhost hello]$ curl http://127.0.0.1:8080/hello-1/HelloServlet?foo=b$'\xc3\xa5'r Hello bÃ¥r [slydell@localhost hello]$ and the jboss console output says: 09:18:19,483 INFO [stdout] (http--127.0.0.1-8080-1) Hello bÃ¥r I can change this output by adding JAVA_OPTS="$JAVA_OPTS -Dorg.apache.catalina.connector.URI_ENCODING=UTF-8" to the standalone.conf. With that flag I get: 09:20:57,780 INFO [stdout] (http--127.0.0.1-8080-1) Hello bår But when I run the curl script on wildfly 8.1.0.Final I get different results. I know that the catalina flag has no effect on undertow, and I have also tried all the workarounds I've seen, e.g. * implement a CharacterEncoding filter * set encoding in jboss-web.xml * set default-encoding in servlet-containter in the standalone.xml * set encoding in the http-listener in the standalone.xml None of these workarounds have any effect. I always get the same result: 09:22:42,330 INFO [stdout] (default task-1) Hello bￃﾥr which does not look like anything I've seen in UTF-8 or ISO-8859-1. If I could get the same output as I do in the jboss 7.1.1.Final (without the catalina flag) I would be very happy. The standard non-modified jboss 7.1.1 gave me this output: 09:31:11,723 INFO [stdout] (http--127.0.0.1-8080-1) Hello bÃ¥r So my question is, how do I modify/configure wildfly so that I get the same output as I do in the standard jboss 7.1.1.Final? I have tried the known workarounds, and they did not change any output.
