jython

问题 I'm trying to write an object inspector for Java objects in Jython, and I want to determine how many arguments a given Java method expects. Is there any way to do that in python, or do I have to use Java reflection for that. To explain, I'd like to call all "get..." methods of a Java object that don't take any arguments: from java.util import Date, ArrayList def numberOfArguments(fct): # Some magic happens here return 0 def check(o): print("") print(type(o).name) for fctName in dir(o): if not

问题 Jython doesn't have the -m option, and it raises an error with from .utils import * . The solution is not to use relative path sys.path.insert(0, os.path.dirname(__file__)) from utils import * As I need to use the code both Jython and CPython, I came up with this command: try: from .utils import * except Exception: # Jython or Python with python context/context.py invocation sys.path.insert(0, os.path.dirname(__file__)) from utils import * However, Jython doesn't seem to catch the exception,

问题 I am trying to write a simple Liferay portlet in Python.

问题 I'm having problem with this Random java thing in jython. I'm coding bukkit plugins in python. Here's the code: class hween(PythonPlugin): def CandyChance(self): chance = self.cfg.getDouble("main.candydropchance", 50) / 100 #in config, it's 10, so I must do this to get it like 0.1... return chance @hook.event("block.BlockBreakEvent", "HIGHEST") def onBlockBreakEvent(event): chance = pyplugin.CandyChance() print chance #When I print chance out, it's 0.1 (10 is in config) which is good I

问题 I'm trying to change WebSphere's Log Detail Levels with a Jython script: .. AdminTask.setTraceSpecification('[-serverName server1 -nodeName qnode -traceSpecification com.ibm.*=all=enabled]') AdminConfig.save() .. After successfully running the script I'm checking "Logging and Tracing > {server_name} > Diagnostic trace service > Change log detail levels.

问题 I am accessing a python script using jython and apparently the _winreg module is not supported. Are there any alternatives to this module?

问题 I'm writing a code in Jython, that will copy part of one picture into an empty picture, but I want it to copy (let's say) 10 pixels less with each next row. I don't think I make sense, let me explain with an example. A picture 100 pixels by 100 pixels, the program will copy the first row (100pixels) of pixels into the new picture, but for second row of pixels I want it to copy only 90 pixels, then for the third row 80 pixels, and so on. Here I have a code that will copy part of a picture, but

问题 This is what I've tried... from sun.misc import Signal from sun.misc import SignalHandler class InterruptHandler(SignalHandler): def handle(self): print "Shutting down server..." Signal.handle(Signal("INT"),InterruptHandler()) It's based on this http://www.javaspecialists.co.za/archive/Issue043.html, but evidently I'm missing something. 回答1: Looks like a bug in Jython. There are some workarounds given there. 回答2: I was facing similar problem before. This is how I get it resolved. First,

问题 While trying to run Jython Scripts in Eclipse using PyDev, I noticed that the Jython run configuration was not pulling the java classpath value from maven/m2eclipse. Has anybody configured eclipse so that PyDev pulls the correct classpath from maven?
