    Default launching application with java command line

    Hi all,

    I have been stuck doing this for few hours, i appreciate if someone can help me out!

    I have two classes;

    Java Code:
        package test;  
        public class TestingClient {  
             * @param args 
            public static void main(String[] args) {  
                // TODO Auto-generated method stub  
                System.out.println(new Client().getCounter());  

    Java Code:
        package test;  
        class Client {  
            private int counter;  
                counter = 10;  
            public int getCounter() {  
                return counter;  
    I'm running ubuntu 11.10 and i have tested java and javac and they work.

    The following is my directory structure:
    Java Code:
    the current directory is src

    I used:

    Java Code:
    and it created the class file TestingClient.class inside src/test

    Java Code:
     javac -d ../classes
    and it created the class file Client.class inside Testing/classes

    now when i use:

    Java Code:
     java -cp ../classes test.TestingClient
    i get this error message:
    Error: Could not find or load main class test.TestingClient

    what i'm doing wrong?

    PS: later on, i put both classes inside the bin folder inside the project folder and java command line worked! could it be the -cp?

    Default Re: launching application with java command line

    The TestingClient class is in the test package. The java program will look in a test folder for the TestingClient.class file.
    You say that the TestingClient.class file is in the classes folder, not a test folder.

    The classpath for the java command should point to the folder containing the test folder. The test folder should contain the TestingClient.class file.
