NETLink in Mathematica 7 may be unable to locate the kernel without
some assistance if you've never launched the front end on the machine
using the web server user account.
If MathLinkFactory.CreateKernelLink() can't find the kernel, there
are a couple different things to try:
- Manually specify the location of the kernel. For example, if
Mathematica is installed in the default location:
MathLinkFactory.CreateKernelLink("-linkmode launch -linkname
""C:/Program Files/Wolfram Research/Mathematica/7.0/MathKernel.exe""")
OR
- While logged in to the server interactively as the web server user,
start the front end on the server machine and then close the front
end. After doing this once it should never be required again on that
machine, NETLink should be able to find the kernel from that point on
without being told where it is.
The code that locates the kernel has been improved in the NETLink
version included with Mathematica 8.
