jython

问题 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! 回答1: Drag this image in the entry bar in your browser. The

问题 In reference to hooking into PIP from Jython, It looks like, possibly, PIP is included with Jython: How can I install various Python libraries in Jython? Jython easy_install error How can I use jython setup.py install? How, specifically, from Jython itself, is PIP invoked? Both to install a package and, more importantly, to import that package for reference? I've seen no specific code examples written in Jython. 回答1: Once Jython 2.7 is installed to ~/ then: thufir@doge:~$ thufir@doge:~$

问题 In Python one is used to doing def runTaskInNonEDT(): pass tRunTask = threading.Thread( target = runTaskInNonEDT ) tRunTask.start() In Jython, I find that if I want to submit a method to the EDT I have to go def makeRunnableClass(): class RunnableClass( Runnable ): def run( rSelf ): pass return RunnableClass SwingUtilities.invokeAndWait( makeRunnableClass()() ) obviously you then have all the attendant questions about passing parameters, etc. I was just wondering if there might be a snappier,

问题 I'm wondering if it is possible to call ImageJ from a standalone Python IDE. I want to begin image processing in ImageJ without opening the ImageJ Jython interpreter. I'm not clear if this is possible given the differences between Python & Jython. 回答1: If your goal is to develop Jython code in a Python IDE, then see chapter 11 of the Jython book: Using Jython in an IDE. If your goal is to somehow integrate native Python with ImageJ (i.e., not using Jython): it is not a solved problem yet. But
