Re: JESS: Setting slot values using Java api

You can't construct a Value with a type RU.ANY.

If the Slot doesn't provide the information, you'll have to obtain this
information from elsewhere; in getJessValue you have the value as a String,
and no other information. With a String being passed to the Value
constructor, you have the options RU.STRING and RU.SYMBOL. -- See Javadoc
for jess.Value.
