[Jython-users] newbie question! - How to run a generated class file

[Rajarshi G. <raj...@pr...>]

Hi,
  just downloaded Jython and and have compiled one of my .py files to a 
.class file with the command:
 ../../jython-2.0/jythonc --deep -A org.python.modules  xml2.py

However when I try to run the .class file I get the error:

Exception in thread "main" java.lang.NoClassDefFoundError: 
org/python/core/PyObject

How can I fix this?

TIA,

You need to include the jython.jar in your CLASSPATH, either in the envir=
onment
or on the commandline.
The jython.jar file is located in the jython installation directory, same=
 place
where the jython command lies.

Include jython.jar in the CLASSPATH.

[Jython-users] Locking a variable in jython

[R D. <rd...@cr...>]

I am working on a jython script that starts multiple threads. The threads 
report statistics (like how many transactions per second) to the monitor 
thread, ie, each thread would need to lock the statistics variable, update 
it and then release the lock.

Could someone send me some sample code that illustrates how to lock a 
variable in jython?



Thanks

import threading

lock = threading.Lock() # the lock
variable = 1 # the variable


# somewhere else
lock.acquire()
varaible = 2
lock.release()
