Is anyone using AJAX and SOAP to get data from an iLON in a non IE environment?

If you have successfully mastered this I would like to see a sample document if you can share. I think Lon Man has done this but he has not been around in quite some time.

I have tried it but i get an error response from the iLON something like ...
' No RPM for the file and method combination'. I have no idea what this is referring to and have not been able to get past this point.

Any help would be appreciated.
