Error when using java -classpath command

I have a class, test, as follows

import java.io.File;
import java.io.IOException;

import org.ini4j.InvalidFileFormatException;
import org.ini4j.Wini;

public class test {

    public static void main(String[] args) throws InvalidFileFormatException, IOException{
        File f = new File("ini.ini");
        Wini ini = new Wini(f);
        int a = ini.get("test", "a", int.class);
        int b = ini.get("test", "b", int.class);
        int c = ini.get("test", "c", int.class);

        System.out.print(a);
        System.out.print(b);
        System.out.print(c);
    }
}

To compile I run the command

javac -classpath ini4j-0.5.4.jar test.java

which compiles without issue, but when I try to run it with the command

java -classpath ini4j-0.5.4.jar test

I get the error Error: Could not find or load main class test.

If I exclude the -classpath ini4j-0.5.4.jar from the java .. test command I get an error Exception in thread "main" java.lang.NoClassDefFoundError: org/ini4j/InvalidFileFormatException ...

The class runs fine in eclipse.

You need to add the directory your compiled class file ends up into your classpath in your java invocation.

In your case

java -cp "ini4j-0.5.4.jar:." test

would be what you want, since everything is in the current working directory.

Edit: Updated for completeness ^^. The class path uses a system specific path separator. So for the unfortunate souls using windows it would be:

java -cp "ini4j-0.5.4.jar;." test
