[rules-users] Migration 3 to 4 (replace "->")
In Drools 3 i used the following code (in a DSL file): [when]ist BlaBlub=BlaBlub(number : id -> ( BlaClass.staticFunction( number )) where id can be resolved be method getId in class BlaBlub and staticFunction ist a public static function in a helper class. Drools 4 doesn't allow me this construct, how should this be migrated? Any help is much appreciated Cheers Markus ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Sequentiel Mode
from drools documentation: Sequential mode can only be used with a StatefulSession and is off by default. To turn on either set the RuleBaseConfiguration.setSequentail to true or set the rulebase.conf property drools.sequential to true. when you use it: *java.lang.RuntimeException*: Cannot have a stateful rule session, with sequential configuration set to true somebody there who can solve this mytery?

[rules-users] eval
Hi,
given the following DSL
[when]of type Item=Item()
[when]- Title equals "{value}"=eval(title.isEqual("{value}")
[when]- Event equals "{value}"=eval(id.isEqual("{value}")
[then]Log : "{message}"=System.out.println("{message}");
the dslr File:
expander Test.dsl
rule "Your First Rule"
when
$p : of type Item
- Title equals "test"
- Event equals "test"
then
#actions
end
resolves to (could be seen in the drl viewer)
rule "Your First Rule"
when
$p :Item( eval(title.isEqual("test", eval(id.isEqual("test") ) )
then
#actions
end
so this of course does not work because of the brackets in "eval"
How could i solve this problem? I need the two different eval
conditions, and sometimes they have to be combined.
Thanks
Markus

Re: [rules-users] eval
you're right, but this was just an example for possible functions. In
reality i don't use equal methods here ...
Thanks

[rules-users] pattern
Drools Documentation says: Matches a field against any valid Java Regular Expression. Typically that regexp is a String, but variables that resolve to a valid regexp are also allowed. It is important to note that different from java, if you write a String regexp directly on the source file, you don't need to escape '\'. Example: but "Test\s+" is a valid RegEx (it was valid in Drools 3.x too), but now: SyntaxfehlerRule Compilation error : [Rule name=OnlineStreaming Start, agendaGroup=MAIN, salience=100, no-loop=true] com/p7s1/swi/phoenix/n24/Rule_OnlineStreaming_Start_0.java (19:923) : Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \\ ) What i'm doing wrong here?

Re: [rules-users] pattern
rule "PatternTest"
when
$pli:Item( eval(title.matches("^Test\s*")) )
then
#
end
Having a second look i realize that the DroolsParser should not parse
the pattern string because it's java code ... and i can't use title
matches "^Test\s*" because title may have chars like (,\ and so on
that resolves into a RuntimeException (sth. with Groups not closed in
RegEx).

[rules-users] BRMS
Hi, i tryed to deploy the BRMS on a WebSphere Server, but i get incompatibility errors. It seems BRMS can not be used with JRE 1.4.x, right? Why? JRE 1.4.x is still very common and often used in enterprises ... Cheers Markus Stacktrace is: Could not be defined due to: (org/jboss/seam/servlet/SeamListener) bad major version at offset=6 This is often caused by having a class defined at multiple locations within the classloader hierarchy. Other potential causes include compiling against an older or newer version of the class that has an incompatible method signature.

[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

[rules-users] RegEx in LHS
Hi all,
i'd like to have following DSL conditions
[condition][]Title contains {value}=title matches {value}
[condition][]Title contains not {value}=title not matches {value}
Currently (using Drools 4.0.3) it seems the parsers resolves to the
first condtion and is matching the word "not" to {value}, so i tried
[condition][]Title contains\s+{value}=title matches {value}
[condition][]Title contains\snot\s{value}=title not matches {value}
but this doesn't help, because second one again matches to the first
rule ... also it is missing one parameter ...
Any solutions?
Cheers
Markus

Re: [rules-users] Combine DSL and Java Code?
Additional the problem is:
if i have to conditions like
when
$item1: Item()
$item2: Item()
-Text is $item1.getText()
-Text2 is $item1.getText2()
it resolves to
Item( title matches $item1.getText(, title matches $item1.getText2() ) )
which is absolutly not usable ...
Cheers

Re: [rules-users] Combine DSL and Java Code?
and what about using java code in LHS:
DSL
[condition][]Text is {value}=text matches {value}
Rule1 (works fine)
when
$item: Item()
-Text is "Hello World.*"
Rule2 (doesn't work)
when
$item1: Item()
$item2: Item()
-Text is $item1.getText()
am i doing sth. wrong or is it impossible?
Cheers

[rules-users] Get compiled Java Code of Rules
Hi, is there any possibility to get the compiled java code of the rules ... could be helpful for several reasons ... Cheers Markus ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

that's right, but can you read bytecode? Or is there a way to serialize into pure Java Code, i think i'll try the way Mark provided ...

Re: [rules-users] Get compiled Java Code of Rules
Here's the way it works for those who are interested
-- create a Packagebuilder and build package
JavaDialect jd = (JavaDialect) builder.getDialectRegistry().getDialect("java");
Field field = jd.getClass().getDeclaredField("src");
field.setAccessible(true);
MemoryResourceReader src = (MemoryResourceReader) field.get(jd);
String[] list = src.list();
for (int z = 0; z < list.length; z++)
{
String name = (String) list[z];
byte[] bytes = src.getBytes( name );
System.out.println(new String(bytes));
}

[rules-users] Basic Question about Errors
Hi,
it's a basic question but since half a year i am not sure how to read the error
[53,61]: unknown:53:61 Unexpected token '('[53,73]: unknown:53:73
mismatched token: [EMAIL PROTECTED],2278:2278=')',<12>,53:73]; expecting type
THEN[65,61]:
which line/position is indicated in the corresponding rule file. Every
time, when i think now i got it the next error shows me i'm not right.
Cheers

Re: [rules-users] OR
ok this works, BUT using a DSL it fails again.
DSL:
[condition][]is a Person=Person()
[condition][]- female=sex == "f"
[condition][]- male=sex == "f"
[condition][]- age {value}=age=={value}
DSLR:
rule
when
($person: is a Person
- male
- age 60
or
$person: is a Person
- female
- age 70)
then
end
resolves to:
|
\/
($person: Person( , sex="m", age == 60)
or
$person: Person(sex="f", age == 70))
the "," seems to be the problem ..

Re: [rules-users] OR
I know that it results in two rules, that's currently my workaround to
write more rules. But for the "real" users (not the developer) it my
be easier to read with "or".
I'll have a look at the drools source and try to fix it ...

[rules-users] Running through Collection using DSL
Hi,
i'd like to do the following in consequence:
for (Iterator it = $collection.iterator(); it.hasNext(); $item = it.next()) {
System.out.println($item);
}
But as always i'd like to use a DSL
[consequence][]For each {item} from {collection}=for (Iterator it =
{collection}.iterator(); it.hasNext(); {item} = it.next()) {
[consequence][]End=}
The Rule:
For each $item from $pli.getItems()
Show $item
End
The DRL Viewer exactly shows what i want to have. But compiling any
rulefile expanding this DSL (also the consequences are not used)
resolve into following errors:
line 68:0 mismatched character '' expecting '"'
[0,-1]: unknown:0:-1 mismatched token: [EMAIL PROTECTED],0:0='',<-1>,0:-1]; expecting type END
or
line 131:80 required (...)+ loop did not match anything at character '+'
line 15:74 no viable alternative at character '\'
The reason theems to be
[consequence][]End=}
But why?? Any suggestions, thans very much in advance
Cheers
Markus

Re: [rules-users] Unable to fire Rules
Hi,
your rules represent the following Java Code (the system.out are just
to see the result of matches)
public static void main(String[] args)
{
// You're rule
System.out.println("ABC-834".matches("ABC-834-test-100.edi"));
//false
System.out.println("XYZ-834".matches("ABC-834-test-100.edi"));
// false
System.out.println("834".matches("ABC-834-test-100.edi")); //
false
so it could never work
but maybe this is what you want to have
// m.fileName matches .*+fileMask+.*
System.out.println("ABC-834-test-100.edi".matches(".*ABC-834.*")); //true
System.out.println("ABC-834-test-100.edi".matches(".*XYZ-834.*"));
//false, if this should also be true because fo the 834 you have to
use regex grouping with an optional group before the -
System.out.println("ABC-834-test-100.edi".matches(".*834.*"));
//true
}
Cheers
Markus

[rules-users] Using global in LHS
Hi, again a question, any body had success using globals in LHS? Following DSL [condition][]is a Item=Item() [condition][]-is of type Advertisment=advertisment contains catId rule when $pli: is a Item - is of type Advertisment then // do whatever you want end catId is a member of Item advertisment is a Integer[] array set as global comiling ends with: Unable to create Field Extractor for 'advertisment' of '[ClassObjectType It works fine if advertisment is a member of Item, but i want to have it as global ...

[rules-users] Consequence Restriction
Hi,
i have on DSL and several DSRL files. What i want to do is to restrict
the usage of consequence parts. Means
I have to possible kind of objects in my workingmemory, e.g. Item1 and Item2.
Item1 has a methode setValue1(), and Item2 setValue2()
my DSL has to possible consequence lines
[consequence][]set value1 {value} for {item}={item}.setValue1({value});
[consequence][]set value2 {value} for {item}={item}.setValue2({value});
so now you can use both consequences for the objects but you
shouldn't. currently at runtime an exception will occur. Is it
possible to check this fault at compile time?
Cheers
Markus

[rules-users] RuleFlow Groups and retraction
Hi, one question about using ruleflows: 1. i have a ruleflow consisting of 2 Nodes 2. i insert 2 facts 3. the 2 facts match the condition in rule for the second node, so when inserting an activation is generated 4. but the rule in the first node will retract one of the 2 facts 5. it seems the activation for the second node is not cancelled also i do a retract in the rule 6. now the activation in second node tries to execute and results in a NullpointerException What do i do wrong? Cheers Markus ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

i'll try to make a simple example and send it, currently i found a dirty hack.

Re: [rules-users] RuleFlow Groups and retraction
Here the situtation in my application (small sample application works, i checked that, so up to 99% there's a fault in my implementation but currently i'm stuck, maybe someone has an idea what can be wrong): -> startProcess results in 2 Activations -> first: Fact 1 and Fact 2 on rulenode1 -> second: Fact1 and Fact 2 on rulenode2 -> firing -> first activation retracts fact 2, so clearly second activation has to be canceled so i debugged my application and i clearly see that the activation on rulenode2 is not canceled, the ReteTuple on rulenode2 is never fetched from the nodememory to set to cancel ... I checked my hashCode and equality methods but they seem to be ok. The rules resolve to a very big rete network because of complicated conditions. The conditions of rule1 and rule2 are nearly the same. Anyone has an idea whatelse i can check to fix this issue, any help is appreciated, Cheers Markus BTW: the only thing i can't do is show my application, i'm also sure no one wants to see a WebSphere EAR with lots of classes ...
