I was trying to make Sahi work on windows server 2008 but when I start sahi I got this exception:
Exception in thread "Thread-0" java.lang.NullPointerException
at net.sf.sahi.util.Diagnostics.run(Diagnostics.java:13)
at java.lang.Thread.run(Thread.java:619)
As Narayan said it should be working fine even if I get this exception,
But after I run this script, there's another exception:

Any idea? Thank you.

    Hi,

    Open sahi/config/os.properties and add Windows\ 2008=xp after Windows\ XP=xp

    So it may look like: 
    Windows\ XP=xp
Windows\ 2003=xp
Windows\ 7=xp
Windows\ 2008=xp
Windows\ NT=nt
Windows\ 2000=nt
Mac\ OS=linux
Linux=linux
Mac\ OS\ X=linux
Solaris=linux
SunOS=linux
HP-UX=linux
AIX=linux

    Explanation: Sahi needs to monitor and kill browser processes after each script. But the commands for getting the list of processes are different for various operating systems. In order to fix this, we have moved the various PID extracting and killing commands to os.properties.

    Most Windows OSes after XP use tasklist and taskkill, and Sahi should have defaulted to XP in case the OS was not listed in os.properties. We have fixed this in the coming build. Mean while please make the above mentioned change and let us know if it works for you.

    Regards,
    Narayan

    Hi Narayan,

    I forgot to tell you I alreay changed the os.properties file like you said before I posted my topic.
    But it is not working. Where else do I need to change to make it work?

    Let me have a look.

    Meanwhile, could you run "tasklist" without quotes on a command line and tell us whether that works?
