Example of passing parameter to an AdHocCommand

Version 1

    We're using the new AdHocCommands in Smack 3.1.1. I needed to pass a parameter to a RemoteCommand. From the spec (http://xmpp.org/extensions/xep-0050.html) I could see the XML that I needed, but it wasn't that obvious to me how to use the new Smack API to accomplish this. Here's psuedo-code for what I got to work.


    The basic idea is that the server creates a form with one field in it, and the client code makes two requests - one to get the form, and one to send the completed form.


    Here's the client code:


            XMPPConnection con = ...;
            AdHocCommandManager manager = AdHocCommandManager.getAddHocCommandsManager(con);
            RemoteCommand command = manager.getRemoteCommand("agent@" + con.getServiceName() + "/siddev", "gatherlogs");
            if ( command.getForm() == null) {
                throw new Exception("Didn't get form back!");
            System.out.println("First response from server: " + command.getRaw());
            Form secondForm = command.getForm().createAnswerForm();
            secondForm.setAnswer("myParam", "parameter I want to send");
            System.out.println("Sending form back to Server: " + secondForm.getDataFormToSend().toXML());
            System.out.println("Second response from server: " + command.getRaw());
            System.out.println("Results - [" + command.getNotes().get(0).getValue() + "]");


    Here's a rough idea of the server-side code -


    public class GatherLogsCommand extends LocalCommand {
       public void execute() throws XMPPException {
            Form result = new Form(Form.TYPE_FORM);
            FormField resultField = new FormField("myParam");
            resultField.setLabel("Parameter I need to run command");
         public void next(Form form) throws XMPPException {
            String myParam = form.getField("myParam").getValues().next();
            // do what you need to
            this.addNote(new AdHocCommandNote(AdHocCommandNote.Type.info, "SUCCESS"));
         public boolean isLastStage() {
            return getCurrentStage() == 1;
         // rest of methods are stubbed out
