[rules-users] How to catch Exceptions when firing rules

[Yang Song]

Hi,

Anyone knows how to catch the exception when firing the rules?

I wrapped the session.fireAllRules() method using try...catch, however it
doesn't work: when someone wrote bad code in the rule's action part, the
Exception will be thrown and printed to the stderr, and this will make the
rule engine stop working -- the try...catch outside doesn't help anything.

If  the exception thrown from the rule's action part can be caught
externally, the system can be protected from interrupting Exception.

try {
        _log.debug("Firing rules in : " + getName());

        session.fireAllRules();

} catch (Exception e) {
        _log.info("Error when firing rules: ", e);
}

Thanks,
Yang
