I need help with my Bugs.

Hello guys,
i've got a problem. I had worked on a plugin and when i was testing it, console said, that there is a bug.
Here it is:

Code:

2011-10-21 13:51:16 [SEVERE] Could not load 'plugins\UsefulStuff.jar' in folder 'plugins':

    ... 13 more

i checked TextLanguages so far, but i couldn't find the bug!

can someone help me, please?

That would be great!

PS:Sorry for my bad english, i'm german

 

I'm pretty sure this is because you didn't name your packages properly. You should post your plugin.yml file, aswell as show us the name of your package namespace, I am willing to bet the problem lies somewhere there (with how you've structured your plugin).

And without the source, don't expect too much help...

 

Code:

Caused by: java.lang.NullPointerException
    at me.cornyfisch.UsefulStuff.TextLanguages.setupDEPromts(TextLanguages.java:26)

Post line 26 of the class (and maybe a few more) or the code for the method setupDEPromts. That will help a lot.

 

I'm pretty sure you try to access something which returns null in TextLanguage.java on line 26. I'm not sure, but do you try to start a new thread on that line? If you really don't find the error, show us the full code of the TextLanguages.java file, please.

Ich bin mir ziemlich sicher du versuchst in TextLanguage.java bei Zeile 26 auf etwas zuzugreifen das null zurückliefert. Ich bin mir nicht sicher, aber kann es sein das du bei dieser Zeile einen neuen Thread starten willst? Wenn du den Fehler wirklich nicht findest, zeig uns bitte den gesammten Kot ( ) der TextLanguage.java Datei.

//EDIT: Wow, should stop to write so slowly...

 

OK, this my first thread, sorry.

here the plugin.yml

Code:

name: UsefulStuff
main: me.cornyfisch.UsefulStuff.UsefulStuff
version: 0.1
description: Adds some useful stuff to Bukkit.
author: Cornyfisch

commands:
    weather:
        description: Changes the weather.
        permission:
        usage:
            /<command> {rain|thunder|sun}

the TextLanguages class:

Code:

package me.cornyfisch.UsefulStuff;

import java.util.Map;


public class TextLanguages {

    private Map<enumPromt, String> dePromts;
    private Map<enumPromt, String> usPromts;
    private Map<enumPromt, String> frPromts;
    private Map<enumPromt, String> esPromts;
    private Map<enumPromt, String> itPromts;

    public void setupPromts() {

        setupDEPromts();
        setupUSPromts();
        setupFRPromts();
        setupESPromts();
        setupITPromts();

    }

    private void setupDEPromts () {

        dePromts.put(enumPromt.noPermissions, "Du hast nicht das Recht, diesen Befehl zu nutzen!");
        dePromts.put(enumPromt.errorTooMuchArgs, "Zu viele Parameter!");
        dePromts.put(enumPromt.errorNoArgs, "Du musst einen Parameter angeben!");
        dePromts.put(enumPromt.errorNotEnoughArgs, "Zu wenig Paramter!");
        dePromts.put(enumPromt.weatherNoSuchWeather, "Wetter nicht vorhanden. Es gibt: \"thunder\", \"rain\" und \"sun\"!");

    }

    private void setupUSPromts () {

        usPromts.put(enumPromt.noPermissions, "You don't have permission to use this command!");
        usPromts.put(enumPromt.errorTooMuchArgs, "Too many arguments!");
        usPromts.put(enumPromt.errorNoArgs, "You have to specify a argument!");
        usPromts.put(enumPromt.errorNotEnoughArgs, "Too little arguments!");
        usPromts.put(enumPromt.weatherNoSuchWeather, "Ther is no such weather. There are: \"thunder\", \"rain\" and \"sun\"!");

    }

    private void setupFRPromts () {
  
    }

    private void setupESPromts () {
  
    }

    private void setupITPromts () {
  
    }

    public String getPromt(enumLanguage language, enumPromt promt) {

        switch (language) {

            case de:

                return dePromts.get(promt);

            case us:

                return usPromts.get(promt);

            case fr:

                return frPromts.get(promt);

            case es:

                return esPromts.get(promt);

            case it:

                return itPromts.get(promt);

            default:

                return usPromts.get(promt);

        }

    }

}

and the onEnable method in the main class:

Code:

    public void onEnable() {

        log("[UsefulStuff] has been enabled!");
        setupPermissions();
        setupNodes();
        textLang.setupPromts();

    }

    private void setupNodes() {
        
        Nodes.put(enumNode.weather, "usefulstuff.weather");
        Nodes.put(enumNode.time, "usefulstuff.time");
        
    }

i hope i don't missed something

 

enumPromt, which is used on line 26 is never defined, so null...

 

oh, oh, oh, i'm a bit, ahm, STUPID!!!

the promts must be intalizie(or something like this^^) with = new HashMap<enumPromt, String>;

i noticed this when looked on my postings!

sorry for that, my mistake.
