If Jess is saying that there's no such variable ?text, then the
variable is not defined in this context. Just as in Java, local
variables defined inside a function, for example, aren't available
to code outside the deffunction.

Well, you're not sure because of that empty catch block! If you get a
JessException , a NullPointerException, or a ClassNotFoundException (if
the driver isn't found) they'll all end up in that empty catch block,
and you won't hear about it. That block ought to rethrow as a
JessException too, and then you *will* know what's going wrong!
Never, ever, ever write empty catch blocks, unless you *really* know
what you're doing.
