If it s a Maven project then Netbeans is running your application using the exec-maven-plugin so you ll need to append your options onto the existing exec args property found in the Run Maven dialog  This dialog can be accessed from the the Output window by pressing the yellow double arrow icon

Create the Java code that can receive an argument as a command line argument   class TestCode      public static void main String args             System out println  first argument is    args 0             Run the program without arguments  press F6   In the Output window  at the bottom  click the double yellow arrow  or the yellow button  to open a Run dialog   If the argument you need to pass is testArgument  then here in this window pass the argument as application args testArgument    This will give the output as follows in the same Output window   first argument is  testArgument   For Maven  the instructions are similar  but change the exec args property instead   exec args -classpath  classpath package ClassName PARAM1 PARAM2 PARAM3   Note  Use single quotes for string parameters that contain spaces

I am guessing that you are running the file using Run   Run File  or shift-F6  rather than Run   Run Main Project   The NetBeans 7 1 help file  F1 is your friend   states for the Arguments parameter      Add arguments to pass to the main class during application execution    Note that arguments cannot be passed to individual files    I verified this with a little snippet of code   public class Junk       public static void main String   args                for  String s   args              System out println  arg - gt      s             I set Run -  Arguments to x y z   When I ran the file by itself I got no output   When I ran the project the output was   arg - gt  x arg - gt  y arg - gt  z
