Building our own UI for Drools
by kapokfly
Due to some reasons (for example, build a consistent UI within our own
application, easier to work with our own meta data, don't want SSO etc), we
are considering to build our own UI to generate Drools rule file basing on
the user input via the UI , has anyone tried this before? Is there any
library shipped within Drools Gunvor can be used to be easier to work with
Drools rule syntax?
Thanks,
Ivan

Drools Guvnor API information?
by Vikas Hazrati
Hi,
I am looking at using Guvnor for our project where users would be creating
rules using our UI. For this i need to add / modify rule or any asset for
that matter using an api.
Unfortunately, i could not find enough documentation to suggest the best way
to use the REST api, which I guess is provided by Guvnor. Could someone let
me know the location of where i can get some information for this api. I
also see that the issue GUVNOR-1080
(https://issues.jboss.org/browse/GUVNOR-1080) is marked resolved so the api
should exist right? or that we cannot access it remotely until we have the
Atom Pub Interface done?
Help appreciated .

Debug rule functions ?
by ipeshev
Hello,
could some give me some tips for debugging *functions* in .drl ?
by now I'm not able to debug *inside the functions* which are called by the
rule sequence.
I follow the
http://docs.jboss.org/tools/3.0.0.GA/en/drools_tools_ref_guide/html_singl...
JBoss Drools Tools Reference Guide but what is show there is how to debug a
very simple *rule sequence*. I have no problem with that - following the
guide everything is ok.
BUT
There is nothing shown about a more complex case when there are functions
(java-like) in the .drl file and the rule calls one or more of these
functions. And one function calls another etc. (just like in normal
programming)
When a put a breakpoint inside functions I cannot debug them.
I can only debug the *rule* ("then" section)
Any help would be appreciated?
Or any official info if this supported at all.
versions etc.
Best Regards
Ivan

Decision Table Help
by qwertyqwerty
hi
I was wondering if I could get some help on how to achieve something using
an Excel based decision table to do the following:
I have an ArrayList of Objects.
The Object will contain: name, value, result
In my spreasheet i need to check to see if the value confroms to a
particular regex, and set the response in the <result> of my Object.
Each name will have a different regex applied to it.
Does anyone have any suggestions on the best way/steps to achieve this?

java.lang.OutOfMemoryError: Java heap space
by vdelbart
Hello,
In my tests of the 4.0.3, I have some : java.lang.OutOfMemoryError.
So, I try a simple test with 10.000 sequential execution of 1 rule with no
context and just a workingmemorylogger and I have the error :
java.lang.OutOfMemoryError: Java heap space
My code is :
public class ExecReglesMemotyTest
{
private static final Reader DRL = new
InputStreamReader(ExecReglesMemotyTest.class
.getResourceAsStream("/rules/exemple.drl"));
private static final String FICHIER_LOG = "session";
/**
* @param args
*/
public static void main(String[] args)
{
try
{
PackageBuilder builder = new PackageBuilder();
builder.addPackageFromDrl(DRL);
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage(builder.getPackage());
for (int i = 0; i < 10000; i++)
{
StatefulSession session = ruleBase.newStatefulSession();
WorkingMemoryFileLogger logger = new WorkingMemoryFileLogger(session);
logger.setFileName(FICHIER_LOG);
session.fireAllRules();
logger.writeToDisk();
session.dispose();
}
}
catch (Exception e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
with this rule (doesn't matter):
#created on: Fri Nov 09 15:48:45 CET 2007
package initPackage
#list any import classes here.
rule "ERG9"
when
then
end
I try this in 4.0.1, and it's working (no OutOfMemoryError)
What's the problem ?
thanks for any information,
V.
