The test case is simple and is shown below using a java test class

package com.ibm.tivoli.maximo.script;

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.InputStreamReader;

import javax.script.*;

import org.python.util.PythonInterpreter;

import java.io.*;

public class TestJythonDateModule {

	/**
	 * @param args
	 */
	public static void main(String[] args) throws Exception
	{
		if(args.length>=1 && args[0].equals("usejsr"))
		{
			ScriptEngineManager factory = new ScriptEngineManager();
			ScriptEngine engine = factory.getEngineByName("jython");
			BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream("c:\\harrier75\\datetimetest.py")));
			//engine.eval(reader);;
			CompiledScript cs = ((Compilable)engine).compile(reader);
			cs.eval();
		}
		else
		{
			 PythonInterpreter jython = new PythonInterpreter();
			 InputStream scriptStream = new FileInputStream("c:\\harrier75\\datetimetest.py");
	
			 try {
				 jython.execfile(scriptStream);
			 }
			 catch (Exception e) {
				 e.printStackTrace();
			 }
		}

	}

}

The datetimetest.py script is as below


import datetime

today = datetime.date.today()
print today
print 'ctime:', today.ctime()
print 'tuple:', today.timetuple()
print 'ordinal:', today.toordinal()
print 'Year:', today.year
print 'Mon :', today.month
print 'Day :', today.day

When we run the above test java class using the usejsr option - it gives an error as below. the non jsr 223 approach works perfect. This implies the jsr223 approach is broken and does not work for datetime module.

usejsr option

The same thing if I run without the usejsr option I get this output
