Solution

  • There are 2 problems here.

    1. Incorrect directory location for compiling packed classes.
    2. classpath no set correctly.

    Consider you have, source_dir = D:\~\~\src, jar_location = D:\~\~\lib and package is com.example then your steps to compile are:

    • cd to $source_dir
    • $source_dir> set classpath=.;jar_location
    • $source_dir> javac com\example\Examples1.java or $source_dir> javac com\example\*.java

    As per path shared, command to compile should be :

    cd C:\ListenerZipfile\src
javac -cp .;C:\ListenerZipfile\lib\*.jar com\sigma\main\ListenerZipFile.java

    Command to run java program with above path:

    java -cp .;C:\ListenerZipfile\lib\*.jar com.sigma.main.ListenerZipFile
