I think there is something not so obvious on how to address those facts that I'm missing and the online docs aren't very clear about.

But I find it couldn’t work at all! You use it in your com.sample.cep.CEPExample class without an import, so I assume that it lives in com.sample.cep (!confirmed by the listener trace!); Your DRL, however, uses the package com.sample AND Make sure you use the correct naming conventions as well. you could try here That's no my case I think.

OK close January 10, 2011 at 8:22 pm #18574 anonymousParticipant com.embotics.vlm.facade.model.ServerInventoryItem is an abstract class, it does not implement the getType() method defined in one of the interfaces it implements. Do please make sure that you are accessing methods that take no parameters, and are in-fact "accessors" (as in, they don't change the state of the object in a way that It's quite possible that something goes wrong if you have a POJO Sale and a declared class Sale at the same time.

It may be the case that 5.5 was just looking for getters, while later versions require BOTH getter and setter. - I wonder if the declare with attributes is actually considered A "field" is not a field in the sense of a public or private member of a class. http://brrian.net/unable-to/unable-to-create-annotation-for-method-field-for-ejb.html BTW, my IDE is eclipse.

You can also access non getter methods, like "toString()" on the Object for instance (in which case, you do Cheese(toString == ..) - you use the full name of the method Also, there's no difference in accessing (to retrieve attributes for pattern evaluation), except that events have the additional timestamp attribute (unless mapped to an explicit attribute) which is implicitly retrieved when Thanks Mauricio ;)On Thu, Mar 26, 2009 at 11:32 AM, Mauricio Salatino <[hidden email]> wrote: Are you sure that the class that you have in the classpath is the last one, After I read the user guide, and I've write my HelloWorld, but I got the error like this 'Unable to create Field Extractor', when I use getXXX function name nor xxxx
