Hello everybody,
I installed execnet on Windows 7.
However, when running this example:

   gw = execnet.makegateway("popen//python=jython")
     channel = gw.remote_exec("""
         from java.util import Vector
         v = Vector()
         v.add('aaa')
         v.add('bbb')
         for val in v:
             channel.send(val)
     """)

     for item in channel:
         print (item)

I got this error:

Traceback (most recent call last):

I think it's because "jython" is not found.  Try specifying
the path to the jython executable.

Could you tell exactly the line how you specified that path?
You need to be careful with escaping on windows wrt "\" etc.

Maybe "python" in on your system wide PATH?
Try typing "python" and "jython" in a cmdline window.

Thanks Holger,
I thought it was the problem, but even setting the path to jython 
executable I got the error...

Just for test, I tried replacing
gw = execnet.makegateway("popen//python=jython")
BY
gw = execnet.makegateway("popen//python=python")

Here, python executable is found...

The issue seems to be there independent from execnet.  You could try to
print out in C:\execnet-1.1\execnet\gateway_io.py", line 17 what "args"
is and then try to do the call yourself in a little script
(subprocess.Popen(args)) and find out how to make that work.

sorry but can't be more helpful ATM.

here is the full code:
import execnet
import sys


if __name__ == "__main__":

     reload(sys)
     sys.setdefaultencoding('utf-8')
     sys.path.append("C:\\execnet-1.1")
     sys.path.append("C:\\Jython25\\bin")
     print sys.path

     gw = execnet.makegateway("popen//python=jython")
     channel = gw.remote_exec("""
         from java.util import Vector
         v = Vector()
         v.add('aaa')
         v.add('bbb')
         for val in v:
             channel.send(val)
     """)

     for item in channel:
         print (item)

And Output path:
['F:\\Documenti\\Mistieru\\Programmes\\Python\\ExecTest\\ExecTest\\src', 
'C:\\Users\\Lisandru\\AppData\\Roaming\\NetBeans\\7.4', 
'C:\\Windows\\system32\\python27.zip', 'C:\\Python27\\DLLs',

'C:\\execnet-1.1', 'C:\\execnet-1.1', 'C:\\Jython25\\bin']

yes, but I added Jython too, to be sure...

both are working...

thanks holger,
here is the modification added to line 17:
args[0]="C:\\Jython25\\bin\\"+args[0]+".bat"

example is working then.
