you'll have to setup rules that detect the state of the working memory
that then uses semaphores to control which rules can fire.

I'm running into an issue where the || operator embedded in a collect CE
isn't working as expected. The rule I have is
rule Grant Access"
when
$request : AccessRequest($name : username, $ID : sessionID, $loc :
accessLocation, $day : dayOfAccess)
$user : NetworkUser(username == $name)
$group : UserGroup(users contains $user)
$locationRules : ArrayList(size > 0) from
collect (AccessRule((allowedLocation == "ANY" || allowedLocation
== $loc), allowAccess == "false")
from $group.getRules())
then
# access granted
end
The issue I'm having is with AccessRule((allowedLocation == "ANY" ||
allowedLocation == $loc), allowAccess == "false"), this translate to "all
access rules that have the allowed location set to ANY or set to the
location the user is logging in from". I created a UserGroup named "
super.users" that contains a user named "root" and a single rule that allows
access from ANY location. However, when I simulate a login with "root"

Try changing DSL
from
[consequence][]write "{value}" to stdout=System.out.println("{value}");
To
[consequence][]write {value} to stdout=System.out.println( {value} );
And see if it works.

Subject: [rules-users] Combine DSL and Java Code?
Hi,
following example:
Item Class:
public class MyItem {
public MyItem() {}
public String getMessage()
{
return "Hello World!";
}
}
DSL:
[condition][]is of type MyItem=MyItem()
[consequence][]write "{value}" to stdout=System.out.println("{value}");
DSRL File:
rule
when
$item: is of type MyItem
then
write $item.getMessage() to stdout
end
Is this "write $item.getMessage() to stdout" possible in any way?
Currently i'm not able to get it to work ...
Cheers
Markus

Markus, did you tried:
[consequence][]write {value} to stdout=System.out.println({value});
With the line:
write $item.getMessage() to stdout
