[rules-users] Trouble with insertlogical
Hi,
i modified the shopping example from drool 4.0.4 example downloaded from jboss
website in order to have a better understanding of insertlogical.
the rule is as follows
package org.drools.examples
dialect mvel
import org.drools.examples.ShoppingExample.Customer
import org.drools.examples.ShoppingExample.Product
import org.drools.examples.ShoppingExample.Purchase
import org.drools.examples.ShoppingExample.Discount
rule Purchase notification
salience 10
when
$c : Customer()
$p : Purchase( customer == $c)
then
System.out.println( Customer + $c.name + just purchased +
$p.product.name );
end
rule Discount removed notification
when
$c : Customer()
not Discount( customer == $c )
then
$c.discount = 0 ;
System.out.println( Customer + $c.name + now has a
discount of + $c.discount );
end
rule Discount awarded notification
when
$c : Customer()
$d : Discount( customer == $c )
then
System.out.println( Customer + $c.name + now has a
discount of + $d.amount );
end
rule Apply 10% discount if total purcahses is over 100
no-loop true
dialect java
when
$c : Customer()
$i : Double(doubleValue 100) from accumulate ( Purchase(
customer == $c, $price : product.price ),
sum( $price ) )
then
$c.setDiscount( 10 );
insertLogical( new Discount($c, 10) );
System.out.println( Customer + $c.getName() + now has a
shopping total of + $i );
end

[rules-users] Uploading the fact model to the DRools BRMS
Hi, I fixed the Problem.
First I got rid of the Error
[STDOUT] ERROR 16-01 11:42:25,609 (Contexts.java:flushAndDest
royContexts:335) could not discover transaction status ...
by editing the web.xml of drools-jbrms ear. I found that earlier in this
list.
After that my exception changed into
java.lang.UnsupportedClassVersionError: Bad version number in .class
file
So I created my jars with some different Java versions and with jdk 1.6
the exception was gone. I don't why this is, cause drools and JBoss
should work with 1.5.
Cheers Tobi

Hi ,
I got the same problem and wonder if there is a solution for that yet.
I'am using
JBOSS: AS 4.2.2 GA
DBMR: 4.0.4
JAVA: 1.5.0_15
After uploading the jar, editing the import in the package configuration
and finally validating the package I get the following exception:
java.lang.reflect.InvocationTargetException at
sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at
sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.jav
a:39) at
sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessor
Impl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at
org.jboss.seam.util.Reflections.invoke(Reflections.java:21) at.
The import statement should and the packaging of the jar file seems to
be correct. Otherwise there would be a Class not found error but no
exception.
I tried all kinds of packaging: binaries, source and binaries, creating
the jar through eclipse and from cmd.
This is my very simple java class:
package test;
public class MyBean{
public MyBean(){
}
private int number;
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
}
Cheers Tobi
