[rules-users] enums

2008-07-28 Thread thomas kukofka 
Hello,

If have an input object Inputobject which contains an enum Parameter
which contains all allowed parameters of InputObject:

The entries for the parameters are stored in a map:
private HashMapParameter, String stringParameters;

If I try:
io: InputObject ( stringParameters[InputObject.Parameter.ParameterName] ==

something)

I got the error
=Field/method 'InputObject' not found for class 'com.rules.InputObject'Rule
Compilation error

Kind Regards

[rules-users] Filter incorrect abbreviations

2008-07-28 Thread Pete Crenshaw 
Hello Droolers,

I'm a Drools novice and I'm stuck with a basic rule problem.

In my domain I use a list of abbreviations to describe the conditions of a
system.
Before I can check the state of my system I have to verify all applied
abbreviations.

The List of abbreviations is not a fixed list it's more like a combination
of chars, combined in different ways on fixed positions.

This is a small cutout:

A cutout of possible chars at Position 1: A B C D F H
A cutout of possible chars at Position 2: - A C s n b
A cutout of possible chars at Position 3: - A B E F M
A cutout of possible chars at Position 4: - H L O R U

Now it is allowed to combine the following abbreviations:
(another small cutout)

A--O A--R A--UA--L
BAAO BAAR BAAUBAAL

but it is not allowed to combine this:

AA** B-** (* stands for all possible chars on a position)

Now I have 2 basic Questions:

1) How can I pick abbreviations that are NOT allowed?
   I think it's easy to say:

   rule Rule 1
when
  a : Abbreviation( pos1 == 'A', pos2 == '-', pos3 == '-', pos4 == 'O' )
then
  # do something positiv
   end

   But how can I pick up all the wrong combinations without hardcoding them?
   This would end up in a never-ending story.

2) Upgrading the Rule 1 from my 1st Question I'm looking for a way to make
the
   Rules more generic.
   I don't want to hardcode all possible abbreviation combinations.
   How can I realise something like this VERY INFORMAL notation:

   rule Rule 2
when
  a : Abbreviation( pos1 == 'A', pos2 == ['-','D','H'], pos3 == '-',
pos4 == ['O', 'R', 'U', 'L'] )
  # If abbreviation looks like A--O, AD-O, AD-U, AH-R, etc. everything
is fine.
  # It's time for Rule 2 to do something positiv
then
  # do something positiv
   end

   Rule 2 should find all the abbreviations that are build up according to
a set of allowed char combinations.

   OR

   rule Rule 3
when
  a : Abbreviation( pos1 == 'A', pos2 != ['-','D','H'], pos3 != '-',
pos4 != ['O', 'R', 'U', 'L'] )
  # If abbreviation looks like AA-O, AB-U, A-AO, A--K, etc. something is
wrong.
  # It's time for RULE 3 to announce something negative
then
  # announce something negative
   end

   Rule 3 should filter all the abbreviations that are violating a set of
allowed char combinations.

Thanx 2 all droolers in advance.

Pete

[rules-users] Function import problem in BRMS

2008-07-28 Thread Poornima 

Hi All,

I am still a novice in using jboss BRMS web based tool, i have a 
question regarding static function imports. I have added rule file using 
technical rule-text editor.
Any function imports added to this file gives validation errors, with 
error message unknown:4:0 mismatched token and there is no option to 
add import
function in package header. How am i suppose to use static function 
imports from a helper class when BRMS web based tool is used?


Thanks a lot.
Poornima.

Try a simple rule that just checks for any InputObject to make sure you 
have the class imported correctly.


Rule x
when
InputObject()
then
end

[rules-users] enums

2008-07-28 Thread thomas kukofka 
Hi,

I tried this. No problem at all.
I can use enums also like this:
io: InputObject(type == InputObject.Parameter.PARAMETERNAME)
Only this causes the error:

private HashMapParameter, String stringParameters;

public HashMapParameter, String getStringParameters() {
return stringParameters;
}

public void setStringParameters(HashMapParameter, String 
stringParameters) {
this.stringParameters = stringParameters;
}
*
   io: InputObject (
stringParameters[InputObject.Parameter.ParameterName] ==*
*something)  -** Field/method 'InputObject' not found for class
'com.rules.InputObject'Rule
** Compilation error**
*
If I use String instead of Parameter it works again:
private HashMapString, String stringParameters;

*   io: InputObject ( stringParameters[somestring] ==* *something) *

Thomas

RE: [rules-users] database access via JDBC

2008-07-28 Thread Anstis, Michael (M.) 
You can use any technology you like to get data from outside the Working
Memory using the from keyword.
 
Look at the documentation for more details.

Hello,

is it possible to access a database from within the rule file

I only read about access via Hibernate. Is there any JDBC
example?

Re: [rules-users] query or global

2008-07-28 Thread Ingomar Otter 
what are disadvantages and advantages of the following  
possibillities to to

get access to working memory facts from outside:
Is there a reason why you want to use something other than queries?
 I would suggest to use queries _unless_ you have a definitive   
requirement that requires something else. Queries are easy and you get  
constraints for free.
Everything else is just work. ;-) If you need to use logicals, you  
also have to implement an event listener in your facts to track them   
properly.

in java code

[rules-users] Measuring Drools Memory Usage

2008-07-28 Thread Roger Tanuatmadja 
Hi,

Has anyone attempted to measure the incremental memory usage of using
Drools? Anyone cares to share their methodology?

I am currently following the following methodology:
1. Prevent garbage collection from happening by using large Xms Xmx (1024m
in my case), a NewRatio of 2 (I am sure other sizes will work as well) and
verbogegc enabled to confirm that no garbage collection is happening.
2. Use Runtime.freeMemory before and after fireAllRules and measuring the
difference.

The problem with my methods so far has been that after a positive memory
usage (indicating you are using memory), subsequent use case (the same one)
incurs zero memory usage which is very strange.

So I guess my question is 2 fold: anyone care to share their methodology,
and can anyone see what's wrong with mine?

Thanks,

Roger
