Hi Chris

I have done what you said and the location it prints out is:
      d:\documents and settings\localadmin.CCBUILD130D

so I put the mlb directory and SharedMLB.agpkg there, and ran
SharedMLB.agpkg again, and tried to invoke it from the MLB
Controller's Start button, but it still didn't work.

Then, I just modified the name of the mlb directory from "mlb-1.1" to
"mlb" and it works now. I don't know if this is the reason why it
didn't work before.
Channa,

Thanks for noticing that - I'll fix the installation instructions to take it into account.

The name difference (mlb vs mlb-1.1) is important.


By the way, could you give me some advice if I want to do something
more about the AG programs? Where could be a good start?
Have a look at:

In particular, the Programmers Manuals and API Reference.

Hi Chris

Thank you for your reply.

I have unzipped the mlb-1.1.zip file into my home directory:
D:\Documents and Settings\localadmin
MLB works OK if I use mlb.exe, but it still doesn't work when I invoke
it from the MLB Controller's Start button.

Channa,

The shared app uses a technique to find the mlb directory and mlb.exe
which may not work very well on Windows. Could you create a plain
text file with the following lines in it?

#!/usr/bin/python

import os

print os.path.expanduser("~")
##### end of file #########

Save it as something like atest.py, then run it from a command shell
and tell me what it prints out (whatever location it prints out is
where the shared app is expecting to find the mlb directory).

I have installed AGTK 2.4 in Windows XP and downloaded MLB for
Windows
and SharedMLB.agpkg, but when I click on "Start MLB" button in MLB
Controller, the mlb application will not start itself. Does anyone
know why?



Channa,

There are 2 ways of running MLB within the AG; either as a Node
Service or as a Shared Application. It looks like you're using the
second method and the Windows version of this was never completed,
meaning that the mlb executable isn't actually run. I'll try to
find some time to fix it in the next few days.



Channa,

You need to unzip the mlb-1.1.zip file (which you downloaded from the
"MLB for Windows" link) into your home directory. If your account
name is "channa", then your home directory will be:
C:\Documents and Settings\channa

After unzipping, you should end up with an "mlb" directory in your
home directory. In turn, the "mlb" directory will contain some more
directories and some files, including mlb.exe, which you could test
as a standalone application first. If that works OK, then it will
work when you invoke it from the MLB Controller's Start button.
