Using multiple .jar with javac

Question

pardon my terminology. I'm trying to use three jar files with a java program for my CS class. The first is funjava, a simplified java language, and the others are class definitions color and geometry. Here is my code and what happens when I try to run it. ``` import colors.*; class Canvas{ public static void main(String [] args){ System.out.println("test123"); Circle cr1 = new Circle( new Posn(1,2), 5, "blue"); Circle cr2 = new Circle( new Posn(5,4), 3, "red"); } } class Circle{ Posn center; int rad; String color; Circle(Posn p, int r, String c){ this.center = p; this.rad = r; this.color = c; } } class Posn{ int x; int y; Posn(int x, int y){ this.x = x; this.y = y; } } ``` The last argument of Circle should be a color from the colors.jar, not a string. ``` niko@niko-laptop:~/Classes/Fundies2$ javac -cp *.jar Canvas.java error: Class names, 'funjava.jar,geometry.jar', are only accepted if annotation processing is explicitly requested 1 error niko@niko-laptop:~/Classes/Fundies2$ ls 1-20…

Accepted Answer

In addition to Romain Muller's answer:

If you want to quickly use all of the *.jar files in the current directory, and you're using JDK 6 or later, you can use a single-asterisk. In a unix shell (like in Linux), you'll need to escape the asterisk:

```
javac -cp \* Canvas.java
```

This works when running the Java application as well:

```
java -cp .:\* Canvas
```

Note the `.:` to tell Java to look in the current directory as well as the *.jar files to find `Canvas.class`.

On Windows, use a semicolon (`;`) instead of a colon as a separator.
