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

salaboy wrote: I'm a newbie, I've never written a WorkItemHandler, I've just read the doc and tried to understand. I came away from the "Exceptions" section of the doc with no idea of whether or how it related to Java Exceptions, and they're not covered elsewhere. All I'm looking for (for now) is to simply throw into the docs (maybe in "8.2.4. Executing work items") what Kris said here, which I think boils down to: "WorkItemHandlers should not throw exceptions of any kind. If an exception is to be handled at the business process level, convert it into a Fault. The WorkItemHandler should also provide whatever other handling (logging, etc.) is desired." I'd also suggest renaming section 3.8 from "Exceptions" to "Faults", and talk about "Fault Handlers", not "Exception Handlers". It might make sense to provide an AbstractWorkItemHandler which wraps executeWorkItem() with sensible default behavior of some kind. But this is less important, IMHO. I agree that the mapping from Java exception to business-process semantics is fundamentally the responsibility of the WorkItemHandler. The framework can help, and can make clear that the responsibility exists -that's all. -Ed -- View this message in context: http://n3.nabble.com/How-to-do-Exception-Handling-tp689387p708851.html Sent from the Drools - User mailing list archive at Nabble.com.
