PUT method does not provide form parameters

To reproduce this situation I just created a eclipse maven project with empty pom.xml and added: pom.xml <dependencies> <dependency> <groupId> io.undertow </groupId> <artifactId> undertow-core </artifactId> <version> 1.4.6.Final </version> </dependency> <dependency> <groupId> io.undertow </groupId> <artifactId> undertow-servlet </artifactId> <version> 1.4.6.Final </version> </dependency> <dependency> <groupId> io.undertow </groupId> <artifactId> undertow-websockets-jsr </artifactId> <version> 1.4.6.Final </version> </dependency> </dependencies> Then created a basic servlet : package undertow.test; import java.io.IOException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; @SuppressWarnings( "serial" ) public class PutTest extends HttpServlet { @Override public void doPut(HttpServletRequest request, HttpServletResponse response) throws IOException { System .out.println( "Put parmameter: " +request.getParameter( "test" )); } } And deployed that code using this simple hello class: package undertow.test; import javax.servlet.ServletException; import io.undertow.Handlers; import io.undertow.Undertow; import io.undertow.server.HttpHandler; import io.undertow.server.handlers.PathHandler; import io.undertow.servlet.Servlets; import io.undertow.servlet.api.DeploymentInfo; import io.undertow.servlet.api.DeploymentManager; public class Deploy { public static final String MYAPP = "/" ; public static void main( final String [] args) { try { DeploymentInfo servletBuilder = Servlets.deployment().setClassLoader(Deploy. class. getClassLoader()) .setContextPath(MYAPP).setDeploymentName( "test.war" ) .addServlets(Servlets.servlet( "PutTest" , PutTest.class).addMapping( "/test" )); DeploymentManager manager = Servlets.defaultContainer().addDeployment(servletBuilder); manager.deploy(); HttpHandler servletHandler = manager.start(); PathHandler path = Handlers.path(Handlers.redirect(MYAPP)).addPrefixPath(MYAPP, servletHandler); Undertow server = Undertow.builder().addHttpListener(8080, "localhost" ).setHandler(path).build(); server.start(); } catch (ServletException e) { e.printStackTrace(); } } } After and executing a simple call using curl like this: curl "http://localhost:8080/test" -X "PUT" -d "test=Putting some value" Or with content-type header: curl "http://localhost:8080/test" -H "Content-Type: application/x-www-form-urlencoded" -X "PUT" -d "test=Putting some value" The out put is the same, no parameter founded: Put parmameter: null
