I'm currently working on a project involve Java and Python. Long story short, I followed some post on ways to access Python file from Java by packaging the file into a jython jar and import into the Java project.

Instead of using "java -jar jython.jar run.py" to call the run.py, anybody know if there is way to call the file from Eclipse (assuming I already add the jython.jar into to my build path?

Thank you so much!

  • Hello Malik, thank you for the screenshot and explanation. Now, the test.py file is in the source folder NOT in the jar that I important. What if I packaged it in the jython.jar? Can you still call it? Commented Jan 26, 2015 at 21:58
  • Why would you do this, if possible? Right click your project in Eclipse and export. You can then export to a runnable JAR that can contain your entire project including both of those files. Commented Jan 26, 2015 at 22:06

How is this William? I've tried you walk you through completely.
Hello Malik, really appreciate you spend time on explaining this. I know how to add jar to build path and use jython jar. My real question is, I have package a python file in the jar, say print hello world, it's not part of the jython.jar. Through command line I can do this "java -jar jython.jar print.py" and it will call the python. Now I want to know how to do this in Eclipse...Thanks for your effort.
I believe so but why would you package script.py in jython.jar? You can export your whole Eclipse project to a jar as is.
Yes, but in your case, if you export your project to a jar, you won't be able to call test.py anymore because test.py will be in a zip file, your src/test.py won't work.
I think it will work src/test.py will just be contained within the JAR.
