That's probably because Java classnames can't contain "<" or ">" and the rules becomes java class files.

Solution A): a solution to this is *escaping*, for example with the "$" character:
"Rule_>" becomes "Rule_$gt$"
"Rule_<" becomes "Rule_$lt$"
"Rule_$" becomes "Rule_$dollar$"
"Rule_£" becomes "Rule_$u1245$" (presuming that 1245 is the unicode for £)
"Rule a" becomes "Rule$space$a"
"Rule  a" becomes "Rule$space$$space$a"

> A KB with the two following rules will not compile:
> {code}
> rule "Rule_>"
> when then end
> rule "Rule_<"
> when then end
> {code}
> Here's a more realistic example:
> {code}
> rule "dollar > euro"
> when then end
> rule "dollar < euro"
> when then end
> {code}
