Yes.

There's a problem in your method CheckMailAddr()
I would go so far to say that the problem is a NullPointerException.

Seriously though, this isn't a problem caused by the servlet, check
the method which generates the exception.
You get the 500 internal servlet error because that method caused a
problem, not for any servlet specific reason.
