Hi,
I am unable to compile the example code for JBoss, could some body help
me out how to go about compiling the example code ? Is there a document
that explains the steps for compiling the example source code ? Please
let me know. Following is the error I am getting while trying to compile
I am a beginner.
I have an ArrayList object - Say BoxList Object containing 10 Box objects .
I need to check if the length of the bos is 10cm on each box object.
How do I write this as rule condition.
Is there any way to write the rule for iterating the BoxList to check the
length of each box

Hi,
I need to know how garbage collection will happen in Drools.
Because my system is taking too much time to execute the
business logic.
Please tell me how to rectify it?
One more question I will generate the email content
Hi Steven,
Yes I thought of that but our business user says this is unacceptable
unless I can write a parser to automatically generate all these
combinations.
The example I use is quite simple. Our business user have quite
complex logic expressions (imagin my example plus a lot of parenthesis
Hi Alex,
Thank you for confirming this. Writing such a builder may take us a
lot of time because our business user is used to free style
Pascal-like authoring using quite complex logic. For example,

Bill,
The way of doing that is using connective constraints as explained by
Steven previously:
$a : Person(age 35 | 25, zipCode == 23546 | == 68590)
This is a new feature that only works in 3.1M1 and later versions.

Vlad,
I think that for Bill's case, the object structure is flatten already
(what is good for rules). Creating nested objects will actually make it
more difficult to write the rules...

Hi Vlad,
Thank you for the help.
Unfortunately I can not change the Object Model as these POJOs are not
used only by myself.

The new version works fine with nested conditional elements and allow
for any level of nesting. You simply must be very careful with OR as the
semantics of OR in a rules engine are not exactly the same as most
people are used to in imperative programming.
Also, the syntax you
'and' is not needed at top level, it is implicitely assumed that all
patters are under an 'and' CE.

Thanks for the reply. The rule you authored worked fine on my new

However, I did notice that the following pattern matching is not working:

To improve my understanding of DROOLS a bit, just a small follow up
question.
If the modification of the business domain model is correct and will result
in the correct behavior, I wonder what kind of performance implications such
modification will bring (to compare with 'flatten' model)? Would

Hi Vlad,
There is a very basic wiki page on it
(http://wiki.jboss.org/wiki/Wiki.jsp?page=DecisionTableTemplates

In terms of the functionality you mention you have your data having
knowledge of the rule templates whereas the current implementation is such
that the data has no knowledge of the

Alan,
Thanks for your reply!
The main reason I was considering creating a rule per row is because it
allows flexible matching: it will allow matching records with
different level of details.
I was also thinking of asserting rows of my lookup table as facts, would
that work? What kind of
