POST parameters HttpRequest

Question

Hello.
I want to use HttpRequest to send a POST to a Servlet and print the response. I want to send a parameter called content.
When I set the location like this it works ok.
var mycontent = "hello";
location:"http://localhost:8080/sign?content={mycontent}";
But I want to set the location as:
location:"http://localhost:8080/sign";
and send the parameter in the onOutput function like this.
onOutput: function(os: java.io.OutputStream) {
                try {
                    os.write(contenido.getBytes());
                } finally {
                    os.close();
            }but I dont know how to specify the parameter "content".
This is my full code
def request: HttpRequest = HttpRequest {
            location: "http://localhost:8080/sign?content={mycontent}";
            method: HttpRequest.POST
            headers: [
                HttpHeader {
                    name: HttpHeader.CONTENT_TYPE;
                    value: "somecontent/type";
                HttpHeader {
                    name: HttpHeader.CONTENT_LENGTH;
                    value: "{testContentSize}";
            onOutput: function(os: java.io.OutputStream) {
                try {
                    println("----onOutput - about to write {testContentSize} bytes to output stream");
                    os.write(mycontent.getBytes());
                } finally {
                    println("----onOutput - about to close output stream.");
                    os.close();
            onInput: function(is: java.io.InputStream) {
                try {
                    println("Preparing to read....");
                    var br = new BufferedReader( new InputStreamReader(is) );
                    while (br.ready()) {
                        println( br.readLine() );
                } catch (IOException){
                    println("An error ocurred while reading from the server.");
                finally {
                    is.close();
            onException: function(ex: Exception) {
                println("exception");
            onDoneRead: function() {
            onDone: function() {
                println("################Done!!!!####################");
        request.start();Edited by: Virux on Sep 4, 2009 6:16 PM

Hello I have found the solution to this.
I deleted the contenttype header. And change the onOutput function
var mycontent = "content=hello";
def request: HttpRequest = HttpRequest {
            location: "http://localhost:8080/sign";
            method: HttpRequest.POST
            HttpHeader {
                    name: HttpHeader.CONTENT_LENGTH;
                    value: "{testContentSize}";
            onOutput: function(os: java.io.OutputStream) {
                try {
                    println("----onOutput - about to write {testContentSize} bytes to output stream");
                    os.write(mycontent.getBytes());
                } finally {
                    println("----onOutput - about to close output stream.");
                    os.close();
            onInput: function(is: java.io.InputStream) {
                try {
                    println("Preparing to read....");
                    var br = new BufferedReader( new InputStreamReader(is) );
                    while (br.ready()) {
                        println( br.readLine() );
                } catch (IOException){
                    println("An error ocurred while reading from the server.");
                finally {
                    is.close();
            onException: function(ex: Exception) {
                println("exception");
            onDoneRead: function() {
            onDone: function() {
                println("################Done!!!!####################");
        request.start();In this example Im not enconding the parameter and value. For this you should enconde mycontent var before sending it
