Question

I’m on ubuntu 10.04

when I try to execute a java program in a directory I get a ClassNotFoundException.

I run the program with this command:

 java -cp . Cli

This should run right? I am in the same directory as the Cli.java file, as you can see from the ls command. I have tried setting the CLASSPATH variable, I believe things broke after this. I did delete the CLASSPATH export from my .bashrc

What can I try?

root@ubuntu:/usr/local/jahmm-0.6.1/src/be/ac/ulg/montefiore/run/jahmm/apps/cli# ls

Answer 1

You’re in the same directory as the Cli.java file, but you’re trying to run it, not compile it… you need to compile it first:

javac Cli.java
java -cp . Cli
