[rules-users] issue with date comparison
Hi, I've a fact which is retrieved from database using hibernate. The date format that comes in is -mm-dd, java.util.Date. The fact has two variables *startDate* and *endDate. *I want to check if the the *current date* lies between these two. Since the current date is not constant I'm trying to use a global variable, which I would setbefore firing the rules. My question is what should be the datatype of this global variable. If I use Date the format is completely different. If I use String it says that date can't be compared with string. However if I hard code the value of current date in *dd-MMM-* rule fire fine. Can someone please suggest me a way to achieve this. Thanks in advance. -- cheers Sumatheja Dasararaju ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] how to loop back in bpmn process
Hi All, I'm trying to write a flow which will loop back (go back to particular node on a condition and start executing nodes from there) on passing a certain validation. I'm confused on how exactly to achieve this. I'm using an OR gateway to split and using XOR to join them back. But the problem is XOR expects always atleast one branch to be true which is not necessarily true here and, if I use AND both should be true which again is not valid here. Can someone suggest a way to achieve this behaviour. Thanks in advance. -- cheers Sumatheja Dasararaju attachment: loopback.png___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Issue while comparing BigDecimal and Long(only while using references)

But when I try to use this feature in the below mentioned way *when Message($dec:Decimalstatus) Message(longstatus == $dec)* This rule doesn't fire even though I have two Message object which satisfy the condition.However, when I try * when Message($dec:Decimalstatus) Message(longstatus == $dec.longValue())* It fires properly.

[rules-users] Getting Current Date in LHS of a rule
Hi All, Can anyone tell me if there is a variable or standard way to get the *current date* and compare with the java.util.Date. I'm trying write the below rule but it doesn't work. It doesn't throw any error but the rule is not at all fired in any case rule new rule dialect java when Message(*testDate new Date()*) then System.out.println(Test); end Do I have to insert a seperate fact which will contain the current date?

Hi wolfgang, Thanks for the response. I've thousands of facts(fetched from DB) which wont be changing very frequently.

[rules-users] jbpm and rule flow
Hi All, I'm a bit confused regarding the differences between the two. I understand that JBPM is a complete workflow with full workflow capabilities. But will the rule-flows continue to work? I've created a sample rule-flow, but it doesn't work until I put the jbpm jars in the classpath. I can remember in older versions of drools I never used to import these jars seperately. Is it recommended to continue writing rule-flows with the latest versions?? I'll be grateful if someone can provide me a link where I can get my confusions cleared.

Can you download the package directly from Guvnor? You could test the

Re: [rules-users] Usings joins in decision tables
Thanks a lot michael. It works fine now. :)
2012/4/5 Michael Anstis michael.ans...@gmail.com
Hi,
I assume you mean XLS decision tables, but if you mean in Guvnor the same
principle applies.
Something like this should be OK:-
CONDITION | CONDITION
Header | SubHeader
$a : id != {param} | $b : id == {param}
null| $a
null| $a
null| $a
null| $a
Please note null above is the word null (no quotatioin marks) and not an
empty value.
You could use any other check in the Header column that is always true
(e.g. id 0 in which case 0 would become the row value, etc).
With kind regards,
Mike

Also, certain factoring steps (contraction of repeated Constraints from different left hand sides) are possible with several Constraint forms.

Whats the advantage of option 2 over 1? Can you give sample code for option

In drl, you could use

I'd say you are using
dialect mvel
There is no try/catch statement in MVEL. You have the options:
(1) Use Java, not MVEL.
(2) Surround the fireAllRules() with try/catch and put it in a loop
that's terminated
if there is no exception.

[rules-users] How to import standard java classe(eg: wrapper classes) inside a drools guvnor.
Hi I am new to drools. Forgive me if the question iam asking is too dumb :P. I want to write java code inside the rules in the drools-guvnor using the standard classes, like parsing a string using wrapper classes. How can i import these java classes? -- Thanks and Regards, Sumatheja Dasararaju Human Being :P ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
