Performance: Stateful vs. Stateless Session
by tonytang
Can anybody help me to explain the performance between Stateful and Stateless
session?
I write a very simple test code to test the performance:
Just a message,if the id is odd then set a attribute to "odd"
if it is even then set to "even".
insert message one by one, and insert 1,000,000 times.
Rule:
rule "even"
when
message: Message()
eval((message.getId() % 2) == 0)
then
message.setOddOrEven("odd");
end
rule "odd"
when
message: Message()
eval((message.getId() % 2) == 1)
then
message.setOddOrEven("even");
end
message class just id and oddOrEven
public class Message {
private int id;
private String oddOrEven;
public Message(int id){
this.id = id;
}
// getter and setter
}
My test code:
// create statefulSession and statelessfulSession out of KnowledgeBase
StatefulKnowledgeSession statefulSession =
kbase.newStatefulKnowledgeSession();
StatelessKnowledgeSession statelessfulSession =
kbase.newStatelessKnowledgeSession();
int messageNumber = 1000000; // total message number
Random random = new Random(); // to generate id
long begin = System.currentTimeMillis();
for(int i = 0; i < messageNumber; i++){
FactHandle handle = statefulSession.insert(new Message(random.nextInt()));
statefulSession.retract(handle);
}
statefulSession.dispose();
long end = System.currentTimeMillis();
long statefulTime = end - begin;
begin = System.currentTimeMillis();
for(int i = 0; i < messageNumber; i++){
statelessfulSession.equals(new Message(random.nextInt()));
}
end = System.currentTimeMillis();
long statelessTime = end - begin;
System.out.println("Stateful session time: " + statefulTime + " Stateless
session time: " + statelessTime);
The result: "Stateful session time: 12158 Stateless session time: 46"
oh my god...
Is there any place is wrong in my code ?

I am able to authenticate with Active Directory but with only a single
organizational unit but not with users of multiple organizational units
This is my organizational structure

JBRULES-3260: Events forced to zero expirationOffset
by Robert Crawford
It seems like ever since I found this, I can't stop tripping this condition.
Basically, while adding the DRL files to the KnowledgeBuilder,
ReteooRuleBase decides it has to reconcile event definitions from different
"packages", so it looks for any that are assignable. At first I thought this
was just a guard against having a parent expire quicker than a child class
and breaking rules for the child. But now I'm getting this condition for A
SINGLE CLASS WITH NO INHERITANCE.
At the root of the problem is ReteooRuleBase line 477:
node.setExpirationOffset( Math.max( node.getExpirationOffset(),
typeDeclaration.getExpirationOffset()+1 ) );
Since neither node nor typeDeclaration have declared expirations, they both
have expirationOffset values of -1. The code evaluates:
max(-1, -1 + 1)
sets the expirationOffset for node to zero, and from then on my objects are
expired literally as I insert them.
If someone could more clearly state the conditions that trip this code, I'd
do my best to avoid them. I've already eliminated inheritance among my
events, but that doesn't seem to be enough.

Define global variables at the top of a rules file
by Martin A
Hello,
I'd like to set global rules variables at the top of a rules file, like so:
global int WELCOME_SCREEN = 1;
so that I may easily refer to them from inside the rules, instead of
hardcoding them somewhere in code. Is this possible?
Best regards,
Martin

Is it actually a property of an enum or rather one of the enum literals?
If it is actually a property, you will need to obtain an instance of the
FrontendScreen enum first. If PLAYGROUND is actually an enum literal and you
want to bind this literal to a variable, use:
$screen: FrontendScreen( this == FrontendScreen.PLAYGROUND )

check if a Enum object is present in condition
by Martin A
Hello,
I try to put a condition in my LHS, such as:
rule "initial_playground_dialog"
#agenda-group "firstTimeUser"
#salience 99
when
$gst :
GameStateController(!hasEventOccurred("initial_playground_dialog"))
$list : List()
$screen : FrontendScreen.PLAYGROUND
then
....
end
where 'FrontendScreen' is an enum and PLAYGROUND is its property. However I
get a syntax error. What's the proper way to check for and assign such a
session object?
Any help is appreciated!
Best regards,
Martin

Problem in adding a Class to PKG
by DerLonG
Hi,
I have a problem when i compile a spreadsheet into a PKG. Hope you can
help me.
(Bevor this i used Guvnor to create a PKG from Spreadsheet, but i decide to
do this by my own)
The question is, how do I add this class to the package builder?
This is my Programm:
public static void main(String[] args) {
try {
final SpreadsheetCompiler converter = new SpreadsheetCompiler();
FileInputStream fis = new FileInputStream(new
File("E:\\temp\\myfirstDecTable.xls"));
final String drl = converter.compile(fis, InputType.XLS);
PackageBuilder builder = new PackageBuilder();
builder.addPackageFromDrl(new StringReader(drl));
Package pkg = builder.getPackage();
} catch (Exception e) {
System.out.println("Error: " + e);
}
}
The Exception:
java.lang.ClassNotFoundException: Unable to find class 'KundenEntscheidung'
at
org.drools.base.ClassTypeResolver.resolveType(ClassTypeResolver.java:215)

org.drools.compiler.PackageBuilder.mergePackage(PackageBuilder.java:1002)
