I'm building a Python UI using Tkinter. For the needs of the program, I've to connect Python with Java to do some stuff, so I'm using a simple Jython script as a linker. I cant use Tkinter with Jython because it's not supported.
Python (ui.py) -> Jython (linker.py) -> Java (compiled in jars)
To call the Jython function in Python I use subprocess
as follows:
ui.py:
cmd = 'jython linker.py"'
my_env = os.environ
my_env["JYTHONPATH"] = tons_of_jars
subprocess.Popen(cmd, shell=True, env=my_env)
Then, in the Jython file, linker.py
, I import the Java classes already added on the JYTHONPATH, and I create an object with the name m
and call to some functions of the Java class.
linker.py:
import handler.handler
m = handler.handler(foo, moo, bar)
m.schedule(moo)
m.getFullCalendar()
m.printgantt()
The thing is that I've created a m
object, that will be destroyed after the execution of jython linker.py
ends. So the question is: Is possible to save that m
object somewhere so I can call it from ui.py
whenever I want? If it's not possible, is there any other way to do this?
Thanks in advance.
I finally solved it by using ObjectOutputStream
.
from java import io
def saveObject(x, fname="object.bin"):
outs = io.ObjectOutputStream(io.FileOutputStream(fname))
outs.writeObject(x)
outs.close()
def loadObject(fname="object.bin"):
ins = io.ObjectInputStream(io.FileInputStream(fname))
x=ins.readObject()
ins.close()
return x
