How to change default user and password for Tomcat?

Question

In my code below, I have created two sounds, sound1 and sound2. Each sound contains a number of samples that allow the same sound to be played simultaneously. The problem is that if I create seemingly more than 6 to 8 AVAudioPlayerNodes with a AVAudioUnitTimePitch for each, the audio gets completely messed up. I can't even play a single sound when I increase the number of samples too high. I'm not sure if my code is wrong, or what the node limit of AVAudioEngine is.

class AudioManager{
    var audioEngine:AVAudioEngine!;
    var mixer:AVAudioMixerNode!;
    var sound1:Sound!;
    var sound2:Sound!;
    init(){
        audioEngine = AVAudioEngine();
        mixer = audioEngine.mainMixerNode; //automatically creates instance of mixer node, output node, and connects

        do{
            try audioEngine.start();
        }catch let e as NSError{
            print("Error Starting AudioEngine \(e)");
        }

        sound1 = Sound(aManager: self, path: "assets/sounds/waterRefill", ofType: "mp3", numOfSamples: 7);
        sound2 = Sound(aManager: self, path: "assets/sounds/balloonCreate", ofType: "mp3", numOfSamples: 2);


    }

    func playSound(){
        sound1.play(1.0, pitch: 1.0);
    }

    func playSound2(){
        sound2.play(1.0, pitch: 1.0);
    }

    class Sound {
        var audioManager:AudioManager!;
        var audioFileBuffer:AVAudioPCMBuffer!;
        var numSamples:Int = 1;
        var audioIndex:Int = 0;
        var sampleList:[Sample] = [Sample]();

        init(aManager:AudioManager, path:String, ofType:String, numOfSamples:Int){
            audioManager = aManager;
            if(numOfSamples < 1){
                numSamples = 1;
            }else{
                numSamples = numOfSamples;
            }
            audioFileBuffer = createAudioBuffer(path, ofType: ofType);
            for (var i = 0; i < numSamples; i++){
                sampleList.append(Sample(sound: self));
            }
        }

        func createAudioBuffer(path:String, ofType:String)-> AVAudioPCMBuffer?{
            let filePath: String = NSBundle.mainBundle().pathForResource(path, ofType: ofType)!
            let fileURL: NSURL = NSURL(fileURLWithPath: filePath)
            do{
                let audioFile = try AVAudioFile(forReading: fileURL)
                let audioFormat = audioFile.processingFormat
                let audioFrameCount = UInt32(audioFile.length)
                let audioFileBuffer = AVAudioPCMBuffer(PCMFormat: audioFormat, frameCapacity: audioFrameCount)
                do{
                    try audioFile.readIntoBuffer(audioFileBuffer)
                    return audioFileBuffer;
                }catch let e as NSError{
                    print("Error loading Audio Into Buffer: \(e)");
                }
            }catch let e as NSError{
                print("Error loading Audio File: \(e)");
            }
            return nil;
        }

        private func runIndex(){
            if(audioIndex < (numSamples-1)){
                audioIndex++;
            }else{
                audioIndex = 0;
            }
        }

        func play(volume:Float, pitch:Float){

            var count:Int = 0;
            while(count < numSamples){
                if(numSamples > 1){
                    runIndex();
                }
                if (!sampleList[audioIndex].pitchPlayer.playing) {
                    sampleList[audioIndex].volume = volume;
                    sampleList[audioIndex].pitch = pitch;
                    sampleList[audioIndex].playSample();
                    break;
                }
                count++;
            }

        }

        class Sample{
            var parentSound:Sound!
            var pitchPlayer:AVAudioPlayerNode!;
            var timePitch:AVAudioUnitTimePitch!;
            var volume:Float = 1.0
            var pitch:Float = 1.0

            init(sound:Sound){
                parentSound = sound;
                pitchPlayer = AVAudioPlayerNode();
                timePitch = AVAudioUnitTimePitch();

                parentSound.audioManager.audioEngine.attachNode(pitchPlayer);
                parentSound.audioManager.audioEngine.attachNode(timePitch);

                parentSound.audioManager.audioEngine.connect(pitchPlayer, to: timePitch, format: parentSound.audioFileBuffer.format);
                parentSound.audioManager.audioEngine.connect(timePitch, to: parentSound.audioManager.mixer, format: parentSound.audioFileBuffer.format);


            }

            func playSample(){
                pitchPlayer.volume = volume;
                timePitch.pitch = pitch;
                print("Sample Play");

                pitchPlayer.play();
                pitchPlayer.scheduleBuffer(parentSound.audioFileBuffer, atTime: nil, options:.Interrupts, completionHandler: {[unowned self]() in

Solution 1

Look at conf/tomcat_users.xml.

Uncomment the roles and users block. Define a role named admin (if tomcat6) or manager-gui (tomcat7). Then, define a user named as you want with the password you like AND the role admin or manager-gui assigned to it.

Restart your tomcat. Test.

Solution 2

Just look for C:\xampp\tomcat\conf\tomcat_users.xml then put your user account within <tomcat-users> tag. For example:

<tomcat-users>
  <role rolename="admin"/>
  <role rolename="manager"/>
  <user username="admin" password="letmein" roles="admin,manager"/>
</tomcat-users>

Also, don't forget to restart your Tomcat server!

Solution 3

This worked for me. Use the admin-gui and admin-script roles as well

<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="admin"/>
<role rolename="manager"/>
<user username="nick" password="1" roles="admin,manager,admin-gui,admin-script"/>

Solution 4

Look at conf/tomcat_users.xml.

My app that plays files using AVAAudioEngine and AVAudioPlayerNodes was not playing sounds on certain devices (worked fine on newer devices like iPhone 6s Plus though). When I reduced the number of nodes on the engine, it worked on the older devices. I am looking into how I can adjust my code to allow it to work on these older devices because node count seems to be the issue.

Thank you for the help, I've edited the file with Notepad ++ and decomented the roles and have tried the role1,tomcat,both and manager ones. But now while I can enter a password I get : HTTP Status 403 - Access to the requested resource has been denied .

What tocmat version are we talking about? 5.5 should have the UserDataBase activated by default in conf/server.xml and conf/Catalina/localhost/manager.xml.
