You don't have to run jythonc or compile any Java code. That is the beauty of using Jython.
Instead, consider writing a .bat or .sh script (depending on your platform) that does something like this:
java -classpath jython.jar;other-jars-as-necessary org.python.util.jython myscript.py
Make sure you use the stand-alone jython.jar, it has everything you need including the standard Python library. Include other jars on the classpath if your Jython script uses other Java classes.
i should build a Platform Independent Apllication that uses two script python (serial communication). Suggested me write whole application in Jython and after compile in .class with jythonc OR write whole application in Java using PythonInterpreter ??
Is there some other way to use python script with JVM ????
