    then
        $ent = EntityAdapter.resize($ent,90);
       end

I don't understand why when I start this rule under eclipse it work just fine.
If I use this application as webService I get this error.
Can anyone help me?

Thanks

To: rules-dev@lists.jboss.org
Message-ID: <18843391.post@talk.nabble.com>
Content-Type: text/plain; charset=us-ascii

Hi ,
The version of Drools that I have used is 4.0.4

I have used ruleflow groups to create my rule file.
It has a split node (XOR) in which I specify a constraint on which a
ruleflow-group is to be selected .

Insert arraylists as facts in the working memory one by one.

The problem I face is that when I insert these arraylists in the same
session , it doesn't evaluate every constraint in the split node .

The work around I am using , it that I create a new session for every
arraylist , this works just fine . But creating a new session always is an
overhead .

Can you please assist me with this situation .

Thank You

Harsh Jetly

Hi,
I'm using drools for testing if the few attributes of my MO are not null.

I construct the rule in the .drl file in following way :

rule "name"
when
condition1
condition2
condition3
condition4
then
consequence
end

I have observed that the drool engine verifies the conditions line by line
(in the sequence they have written). The moment condition fails, control
comes back to the calling method.

I don't want this. I want the control to execute each and every condition
whether true or false and maintain a record of passed/failed conditions.
Something like this :
rule "name"
when
condition1
log the test result --- This statement should get executed
even if condition 1 fails and control should go to condition 2
condition2
log the test result
condition3
log the test result
condition4
log the test result
then
consequence
end

Is this possible in Drools ?

To: rules-dev@lists.jboss.org
Message-ID: <19821365.post@talk.nabble.com>
Content-Type: text/plain; charset=us-ascii

Hi

I have been using Drools Rules Engine in our application for past
couple of weeks.
One of the requirements in our project was to let a user (anyone who is
writing/analysing the rules) find out
what other rules a given rule depends upon. There were a few kinds of
dependencies:
1) Object Attribute dependency: The attributes of an object being used in
the conditional part of a rule
   might be getting modified in the consequence part of another rule. We
wanted all such rules with each rule having its own dependency list.
2) Rule Salience based dependency. A rule having lower salience should be
executed only after a higher (if any) salience rule has already been
executed.
3) Dependency caused by a specific Rule flow. Rules in a ruleflow group
should be executed only if (if any) Split condition gets satisfied.
4) Agenda flow dependency (i.e., one agenda following another)

   We could not find much support for this in the Drools API. Hence we
decided to write our own dependency generator. The tool we are writing
caters to first 3 dependencies. We might even handle the 4th one.
Since Drools is open source, we thought of contributing our bit towards
its development. If the drools team wants I can happily work with them on
getting this functionality plugged in the Drools system.

Thanks
Siddharth

FYI, here are a few more hacks I had to make (after checking out the latest
from trunk) to get guvnor started on tomcat6 and j2se1.5 on WinXP

1) java.lang.NoClassDefFoundError: org/drools/ObjectFilter

It looks like this one moved to the org.drools.runtime package - duplicated
the source file into org/drools and rebuilt.

2) javax.jcr.NamespaceException: http://www.jboss.org/drools-repository/1.0
is not a registered namespace uri

Added the line

drools=http\://www.jboss.org/drools-repository/1.0

to bin/repository/repository/namespaces/ns_reg

3) jsf not found (if you're not running with J2SE instead of J2EE)

Added jsf-api and jsf-impl to the pom (runtime scope should do it)

'<dependency>
<groupId>javax.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>1.2_02</version>
</dependency>

<dependency>
<groupId>javax.faces</groupId>
<artifactId>jsf-impl</artifactId
<version>1.2-b19</version>
</dependency>

cheers
