[rules-users] How to do Exception Handling???

[miguel machado]

Hi,

I'm not sure this will help you out, but in what comes to the system i'm
currently developing (using drools expert), i've got this method
"runRuleEngine" that collects facts and fire rules on them and i am able to
catch any sort of error within the drools execution by surrounding that with
try {} catch (Exception e) {}.

The important part is that it took me a while to figure that out cuz eclipse
didn't force me handle that, as if the called method didn't have "throws"
(it usually shows a compilation error otherwise, right?).

Just a thought.
