I hope someone can help me. I've inherited an application from a previous employee. The handler works completely fine in SP2003 and SP2007 installations, but when I've tried to get it working within SP2010 to no avail.
I'm getting the error:
"There was an error trying to locate the requested file:
Init: The given key was not present in the dictionary."
In SP2003 and SP2007, the httphandler was put in the <httphandlers> section of web.config. For me to get this error, I put the handler under <handlers> in the SP2010 web.config as it just doesn't seem to execute under httphandlers.
Any advice on where I may be able to research/find the solution to get it running under SP2010?
