Hello,
Why this Java code rise a Exception in thread "main"
java.lang.NoClassDefFoundError ?
Thanks,

As was already pointed out by others on this thread, Commons
Configuration requires some other Commons libraries. Detailed
information about which libraries you need at runtime under which
conditions can be found on the "Runtime dependencies" page [1].

package com.test.configuration;
import org.apache.commons.configuration.BaseConfiguration;
public class testCommonsConfig001 {
public static void main(String[] args) {
BaseConfiguration config = new BaseConfiguration();
config.addProperty("intProperty", 22);
System.out.println(config.getInt("intProperty"));
}
}
The output console :
