Unresolved import org.python / working with jython and java?

问题

I'm using Eclipse and I"m trying to create a java program that can run my python code. I'm following the guidelines on this page: http://jythonpodcast.hostjava.net/jythonbook/en/1.0/JythonAndJavaIntegration.html#using-jython-within-java-applications

But when I include these statements at the top:

package org.jython.book.util;

import org.python.core.PyObject;
import org.python.core.PyString;
import org.python.util.PythonInterpreter;

I receive a message saying "The import org.python cannot be resolved." Any suggestions on how to fix this?

Thank you so much!!

1. In the Package Explorer (on the left), right click on your Java project and select Properties.
2. In the treeview on the left, select Java Build Path.
3. Select the Libraries tab.
4. Select Add External JARs...
5. Browse to your Jython installation (C:\jython2.5.2 for me), and select jython.jar. Click OK.
6. Click OK.
