jython

问题 I am pretty sure that python scripts will work in all three, but I want to make sure. I have read here and there about editors that can write CPython, Jython, IronPython and I am hoping that I am looking to much into the distinction. My situation is I have 3 different api's that I want to test. Each api performs the same functionality code wise, but they are different in implementation. I am writing wrappers around each language's apis. Each wrapper should expose the exact same functionality

问题 I am having a tough time getting jython to work properly when run from an Eclipse plugin. I have a simple object factory that loads a python module conforming to a Java Interface. All of this works fine in standalone mode. However, when I package this as an eclipse plugin, I get a different error based on a few variables: Given that my java package is com.foo. 1) If I run without modifying any paths, I get: "No module named foo" 2) If I then add my java jars to the sys.path using:

问题 I'm using Jython from within Java; so I have a Java setup similar to below: String scriptname="com/blah/myscript.py" PythonInterpreter interpreter = new PythonInterpreter(null, new PySystemState()); InputStream is = this.getClass().getClassLoader().getResourceAsStream(scriptname); interpreter.execfile(is); And this will (for instance) run the script below: # myscript.py: import sys if __name__=="__main__": print "hello" print sys.argv How I pass in 'commandline' arguments using this method ?

问题 I'm building Java to Jython bridge class. The task I'm trying to solve is to make Jython to look for python modules in my application working directory (also known as program execution directory). I'm doing so by appending System.getProperty("user.dir") value to the sys.path: pySysState = new PySystemState(); //add working directory into sys.path pySysState.path.append(new PyString(System.getProperty("user.dir"))); log_.info("Jython sys state initialized. sys.path: " + this.pySysState.path);

问题 When reading and using this article it assumes that we have a full object definition with class and mapping (proxy) objects from python to java. Is it possible to only import a method (not defined inside a class, but using internal python class) from a piece of code in python without wrapping it in a class definition (without using the factory paradigm described above). I would have like to do some kind of from myPyFile import myMethod from java, and then use myMethod, directly from java

问题 I just installed Jython 2.5.1. I want to convert my Python file into Java class file and it is instructed on the website to use the jythonc command-line tool but I can't find it. Does anyone know where I could find it? Basically what i was trying to accomplish is to get my Python code running client-side in a browser and the best way seemed to be by creating an applet using Jython. I don't want to create a desktop application and using Silverlight/IronPython is out of the question. Any other

问题 I have a Maven module, that depends on various other Maven dependencies by which I am accessing through my jython code. I am now done, and I would like to compile the project as a .jar, or even just run it without compiling, but I have no clue where to start. Does anyone have any idea how I can run some .py files that accesses some Java libraries in other packages? Also, how can I compile it as a .jar file when all is done and good? Thanks! 回答1: Compiling and integrating python Use the jython

问题 I have an array with Field Names and jdbc Type codes. (Those int codes that you can find in http://download.oracle.com/javase/1.4.2/docs/api/constant-values.html#java.sql.Types.BIT I use a level 4 Driver. I can't figure out how to ask the driver for the corresponding SQL (DDL) Type names. It would be useful in jdbc and in native dialects. I have (CustomerId, 1) (CustomerName, -8) and I want (customerId, INT) (customerId, VARCHAR(200)) Where can I find functions that help me with that? I am

问题 I'd like to use the Jython interpreter with IPython, so that I could use things like tab completion and perhaps the IPython notebook. The IPython FAQ site steps around whether this is possible. I have two questions: Say Jython could work with IPython: how do I actually go about tying them together? When I execute $ ipython , I'm running a Python interpreter. How do I set up IPython so that I run a Jython interpreter? Even if I knew how to do #1, I've searched around and it seems like the

问题 I am getting a syntax error in my code with Jython. Can anyone say what's wrong in the syntax? I am new to this language, don't have much of an idea.
