    From the log, it can be seen that there is a NoClassDefFoundError which means that Java cannot find a class at runtime which was available during compile time.

    json-simple has been included at compile time but not at runtime. The org.json.simple project is packed inside the pre-compiled jar.

    So either configure Eclipse to build a runnable jar which should package the required libraries into the jar, or create a Manifest for the jar and add the dependency with the Class-Path header.

    It might also be useful to use a Java Decompiler to compare the downloaded binary with your compiled jar which should give a clear indication of the differences.
