Running Java program

[Natalia]

I have a program which uses an external library, apfloat.jar.
It compiles and runs in eclipse IDE, but I need to be able to compile and run it from the terminal.

It actually compiles from the terminal when I use the following command:

javac Generator.java -classpath apfloat.jar

but then I have no idea how to run it, when I use this:

java Generator -classpath apfloat.jar

I'm getting the following exception:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apfloat/Apfloat
Caused by: java.lang.ClassNotFoundException: org.apfloat.Apfloat
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)

        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:248)

Could you maybe tell me how can I run this program?

Form the directory containing Generator.class and apfloat.jar try changing the order of the arguments:

java -classpath apfloat.jar Generator

I tried it, and now it doesn't find the class "Generator" (and clearly the class is there):

nataliazon$ ls
Generator.class Generator.java  apfloat.jar     lib             org
nataliazon$
nataliazon$ java -cp apfloat.jar Generator
Exception in thread "main" java.lang.NoClassDefFoundError: Generator
Caused by: java.lang.ClassNotFoundException: Generator

Sorry, I wasn't thinking (more coffee needed).

You also have to tell the java executable that the current directory is part of the classpath.

java -cp .:apfloat.jar Generator

"dash c p space dot colon etc"

It's working now! Big thanks!

You're welcome.
