I am trying a test program for java and .net interoperability. The hello test program works fine with default runtime (java) settings. But not working when I changed the runtime to .NET. I changed fan.runtime to dotnet in sys.props file.

fan - version shows following error . What is missing in my environment / settings?

Thanks in advance

Unless you have a typo in there you're fan.home is:

7C:\app\eng\sdk\fan-1.0.38 

Is that what its saying?

I didn't set fan.home explicitly and I believe, launcher is recognizing it automatically.

fan -version displays the following when the runtime is java

Fan Launcher Copyright (c) 2006-2008, Brian Frank and Andy Frank Licensed under the Academic Free License version 3.0

Java Runtime:

java.vm.name:    Java HotSpot(TM) Client VM
java.vm.vendor:  Sun Microsystems Inc.
java.vm.version: 11.0-b16
java.home:       C:\app\eng\sdk\Java\jre6
fan.home:        C:\app\eng\sdk\fan-1.0.38
sys.version:     1.0.38

But, when the runtime is dotnet, fan -version shows above error and the fan.home is displayed as 7C:\app\eng\sdk\fan-1.0.38 in that error.

If you explicitly set it does it work?

C:>set fan_home=C:\app\eng\sdk\fan-1.0.38

Also you can dump debug information using:

C:>fan --v -version

Hi Andy, still need your help to get me out of this :-)

I did set fan_home correctly in the environment. I verified that using SET command of windows.

Additional info if it helps; I am using Windows Vista Home Edition and .NET runtime is installed at C:\Windows\Microsoft.NET\Framework\v2.0.50727. Also, in the same Framework folder, I do have other versions of .NET runtime including v3.0 and v3.5 (is that causing the problem?).

Below is the debug information;

Thank you Andy, the modified fan.exe that you had mailed is working good for .net runtime.

Thanks again to both you and Brian for this wonderful FAN :-)

Cool. This bug is probably happening to everyone, but for some reason my machine (and I assume others?) work anyways. So maybe it was Vista (I'm on WinXP). In any event I pushed a fix and updated exe's to mercurial.
