    Default .propertie files...

    I created 2 methods 1 for loading string from .propertie file and 1 for savng string to propertie file:

    	public void SavePropertie(String file, String key, String value){
    		Properties properties = new Properties();
    		File xfile = new File("plugins/UnixRPG/" + file + ".properties"); 
    		if (xfile.exists()){
    			//Copying the old part.
    			try {		
    				FileInputStream in = new FileInputStream("plugins/UnixRPG/" + file + ".properties");
    				properties.load(in);
    				in.close();
    			} catch (IOException e) {}
    			@SuppressWarnings("rawtypes")
    			Enumeration em = properties.keys();
    			while(em.hasMoreElements()){
    				String str = (String) em.nextElement();
    				if (str != key){
    					properties.setProperty(str, LoadPropertie(file, str));
    				}
    			}
    		}
    		//Adding new properties line.
    		properties.setProperty(key, value);
    			try {
    				FileOutputStream out = new FileOutputStream("plugins/UnixRPG/" + file + ".properties");
    				properties.store(out, key + ": " + value);
    				out.close();
    				out.flush();
    		} catch (IOException e) {}
    		properties.clear();
    	}
     
    	public String LoadPropertie(String file, String key){
    		Properties properties = new Properties();
    		String value = null;
    		FileInputStream in = null;
    		try {
    			properties.load(in = new FileInputStream("plugins/UnixRPG/" + file + ".properties"));
    			value = properties.getProperty(key);
    			in.close();
    		} catch (IOException e) {}
    		properties.clear();
    		return value;
    	}

    When i load/save Strings from my .propertie file it seems it dose not close the file properly. When my program tryes to delete the .propertie file it fails every time.

    This is the part of the code where i need to delete the file:

    	public boolean onRemove(Player player, Location location){
    		World world = location.getWorld();
    		int x = (int) location.getX();
    		int y = (int) location.getY();
    		int z = (int) location.getZ();			
    		File file = new File("plugins/UnixRPG/signs/toggleblocks/" + world.getName() + "," + Integer.toString(x) + "," + Integer.toString(y) + "," + Integer.toString(z) + ".propertie");
    		boolean sucsess = file.delete();
    		if (sucsess == true){
    			Material1.remove(location);
    			Material2.remove(location);
    			FirstBlockLocation.remove(location);
    			LastBlockLocation.remove(location);
    			return true;
    		}
    		else {
    			player.sendRawMessage(ChatColor.RED + "ERROR: Failled deleting the toggleblocks file.");
    			return false;
    		}
    	}

    It says "ERROR: Failled deleting the toggleblocks file." every time.

    A comment on your programming:
    catch (IOException e) {}

    You should always call printStackTrace() in the catch blocks to show any errors. Your code ignores any errors.

    Ok i added it in SavePropertie method only becose i whant the LoadPropertie to return null if file has not be found or propertie line has not been found. That dose not solve the problem.

    Might be the one of possibility that your resources are not getting free. Means, you are not closing your file and try to delete it while it is in use. Well, paste the error/exception messages here in order you have. Else look at your file writing code.

    The program shows no errors. It just dose not delete the file, puts in sucsess variable false, and as you see in my code prints to player "ERROR: Failled deleting the toggleblocks file.".

    And if i want to add printStackTrace() in LoadPropertie i need to test the reason for calling catch. If the file dose not exsist or if the propertie line dose not exist i need to return null. Not to print the error. If thats not the case i need to call printStackTrace().

    You can tell me how to test that if you know.

    File file = new File("plugins/UnixRPG/signs/toggleblocks/" + world.getName() + "," + Integer.toString(x) + "," + Integer.toString(y) + "," + Integer.toString(z) + ".propertie");
    properties or propertie????
    Also, are you sure it's successfully making new file.

    Ok as others said about your exception handling..
    Always Catch Exceptions

    Also, the reason it wouldn't show any errors/exceptions is because you don't seem to ever use printStackTrace, which is how you find and diagnose your errors.
