Hello there,
I am in the midst of migrating my client server applications (RMI as
middleware) from python 1.5.2 to python 2.7.1. I have done up the migration on
my application servers writen in pure python that runs on the UNIX platform. No
issue.
Now I am encountering an issue where my client which is writen in VB EXE (using
OLE RMI technology, or COM method), unable to call the application servers on
UNIX successfully. The stack trace reveals that it gets stuck at this code, a
TIMEOUT error is returned. It looks like it failes to invoke a COM method and
the code that triggers it resides in win32com\server\policy.py file.
My client program is run on Windows 7, and I haven't tried on Windows XP and I
will try that out next week to see if I encounter the same problem.
Does anyone know if this is related to the TCP RMI call to 10.228.70.137:26000
daemon process, or it is some kind of privilege (like UAC thing in Windows 7),
or security policy depicted in the policy.py perhaps?
Hope to hear some insights on this. Thanks!
