Hi Vlad,
I can certainly look at adding some extra config options to the listeners to
allow an end row/column to be specified. I'm not sure the other things would
be useful to many people (correct me if I'm wrong).
If you do go down the preprocessing option you could use JXL instead of POI

Well, probably to rephrase it, what is the status / thoughts on 'else'

Dirk,
If you aren't sure, just stick with the Eclipse JDT one. If you have
problems with that switch to Janino. Both are embedded jars. Janino is
jdk1.4 only, Eclipse does jdk1.5.

That was a big factor for me, but I understood that "Eclipse" was only usable if
you were generating static rules (in the IDE) for later deployment. Now I'm
No, the "not" conditional element is an existential operator, so the
meaning is what you expressed in your first example. I thought that was
what you were looking for, but apparently it is not.
I never heard about any construction capable of doing what you are
asking for in a rules engine.

My questions include:
*) Why would I prefer one over the other?
So, if used like that, 'not' does not have 'existential' meaning then, but
simple 'negation'? I mean, the expression
not MyObject(field == 'value')
would still mean 'not exists', correct? Would the expression
not (MyObject(field == 'value'))
mean
MyObject(field != 'value')
then. In

In 3.1M1 you can write:
rule X
when
not (
MyObject( aaa == "bbb" ) and
MyObject2( bbb == "aaa" )
)
then
// do something
end
But remember that variables bound inside the "not" block are not avaible
in the consequence for obvious reasons.

I am relatively new to Drools. In my case I need the

Thanks, Oana. I think I'm finally starting to get a grip on this thing :-).

You do not have jdt.jar in your class path. It comes with the dependency
list. If you cannot find it, you can download it from here
http://repo1.maven.org/maven2/org/eclipse/jdt/core/3.2.0.666/core-3.2.0.666.jar
But I recommend you using the one that is coming with the dependency list.
