problem building DRLs using BRMS
by Blanco Emanuele
Hi there,
I've got a problem when building a large DRL (about 40KB) uploaded using the BRMS 4.0.7. If I try to make the build with Firefox, it simply hangs... if I try with IE7, I get a "JavaScript SyntaxError: out of memory". Logs on JBoss AS doesn't mention anything interesting... suggestions/tricks?
Thanks in advance.

having counter in drl
by techy
Hello,
I would like to take 100 sampling facts for rule and persist it in the db
and ignore other data.
How Can I maintain the counter? as global variable? Please clarify with
sample code.
I tried following way and but it does not work as expected.
Ex:
global Integer counter;
rule "get sampling data"
when fact : Foo(some condition) && eval(counter <= 100)
then
counter++
// do some condition
end

drools-compiler sources in GWT build for jbrms 4.0.7
by Blanco Emanuele
Hi there,
in the build.xml file downloaded from SVN for Drools JBRMS 4.0.7, the task "gwt-compile" has a classpath including the drools-compiler sources.
Is it possible to drop that reference and use the drools-compiler jar in that task?
Thank you.

function problem
by Charlie Holland
I'm fairly new to Drools so there may be an easier way to do this. I need to
check to see if any one of a list of tags on an object are in another list
of tags and am trying to do that with a function. the compiler tells me it
can't compile my eval function:
#list any import classes here.
**
*import* com.cp.services.rules.sources.Person;
**
*import* com.cp.services.rules.actions.PersonActions;
**
*import* com.cp.rules.TagCodes;
**
*import* java.util.List;
#declare any global variables here
**
*global* com.cp.services.rules.actions.PersonActions personActions;
**
*function* *boolean* hasOneOf(List list1, String[] list2){
*for* (Object obj : list1) {
String string = (String)obj;
*for* (*int* j = 0; j < list2.length; j++) {
*if* (string != *null* && string.equals(list2[j])) {
*return* *true*;
}
}
}
*return* *false*;
}
**
*rule* "Engineering"
*dialect* "mvel"
*when*
**
#conditions
Person( ageInYears >= 18 ) *and*
*eval* ( hasOneOf(Person(tagList), TagCodes(engrTags)) )
*then*
#actions
personActions.addAction("EngineeringGroup");
*
end

Guvnor and old BRMS clash?? (newbie)
by J Michael Dean
Do Guvnor and 4.07 BRMS store their data in the same location in
JBoss? I naively placed both war files into JBoss, thinking I could
experiment with Guvnor while using BRMS, and it appears that Guvnor
reads and writes to the same repository. Do I need to keep these apps
in separate JBoss instances?
