Try lower case demo in the tnsnames.ora, try double quotes in the login where you have single quotes.

A wild guess, but it has been known to be a problem in some configurations.

What does lsnrctl status say? Maybe you have to add something to the login string like viet.cuenot.mendelbio.com .

Could there be a problem with the web environment not knowing about the tnsnames.ora?
