You are supposed to download the jar files that contain these libraries  Libraries may be used by adding them to the classpath    For Commons Net you need to download the binary files from Commons Net download page  Then you have to extract the file and add the commons-net-2-2 jar file to some location where you can access it from your application e g  to  lib    If you re running your application from the command-line you ll have to define the classpath in the java command  java -cp   lib commons-net-2-2 jar myapp  More info about how to set the classpath can be found from Oracle documentation  You must specify all directories and jar files you ll need in the classpath excluding those implicitely provided by the Java runtime  Notice that there is     in the classpath  it is used to include the current directory in case your compiled class is located in the current directory    For more advanced reading  you might want to read about how to define the classpath for your own jar files  or the directory structure of a war file when you re creating a web application    If you are using an IDE  such as Eclipse  you have to remember to add the library to your build path before the IDE will recognize it and allow you to use the library
