Using existing COM component from web service

[David Wilson]

Hi,

I wrote a maths library as a COM component and would like for people to be
able to access this library via a web service. I've set up the web service,
and all works fine...unless I try to instantiate my COM object from within
any of the web service methods, then either an error 500 is returned if I use
POST to access the web server....or an exception is thrown and a "this method
is not allowed" message is returned if I use a soap client.

Is a web service allowed to access components that are installed on the
server? I've set up my IIS virtual directory to allow running scripts and
executables...and have granted full read, write etc access to all users.

Any advice would be greatly appreciated!

Thanks for taking the time to read this,

Regards,

David.
