I've tried this several ways now. It seems to be something specific
with python and asadmin.bat.
I've tried the following manually in the cmd.exe prompt:
------
C:\temp>c:\glassfish\bin\asadmin.bat list-system-properties
Instance-01
....
properties here
....
Command list-system-properties executed successfully.
C:\temp>echo %errorlevel%
0
C:\temp>c:\glassfish\bin\asadmin.bat list-system-properties
Instance-05 //note that Instance-05 does not exist
Cannot determine type for target : Instance-05
CLI137 Command list-system-properties failed.
C:\temp>echo %errorlevel%
1
C:\temp>ping 019293.com
Ping request could not find host 019293.com. Please check the name and
try again
.
C:\temp>echo %errorlevel%
1
C:\temp>ping google.com

Notice how python never gets the correct returncode from asadmin.bat
but I can get the correct returncode from the shell every time. Can
anyone tell me why Python wouldn't be able to get the correct
returncode for asadmin?
TIA,
Andrew
