Drools Mailing List migration to Google Groups

by Mark Proctor

Drools community member, The Drools team are moving the rules-usesrs and rules-dev list to Google Groups. This will allow users to have a combined email and web access to the group. New Forum Information : http://drools.org/community/forum.html (click link to view) The rules-users mailing list has become high volume and it seems natural to split the group into those asking for help with setup, configuration, installation and administration and those who are asking for help with authoring and executing of rules. For this reason rules-users will be split into two groups - drools-setup and drools-usage. Drools Setup - https://groups.google.com/forum/#!forum/drools-setup (click link to subscribe) Drools Usage - https://groups.google.com/forum/#!forum/drools-usage (click link to subscribe) The rules-dev mailing list will move to drools-development. Drools Development - https://groups.google.com/forum/#!forum/drools-development (click link to subscribe) Google Groups limits the number of invitations, so we were unable to send invitations. For this reason you will need to manually subscribe. The Drools Team

Drools bpmn gateway constraints questions

by mattmadhavan

Hello, I am trying create a few constraints (XOR). I have a .DRL file with 3 agenda-group. I am also using a custom evaluator and few global static functions. Mine is a Stateless Session with bunch of records (Caner records) 1. How do I refer to the current fact? - Can I do something like this? *$cancerRecord : CancerRecord ()* 2. How do I invoke external functions? Can I do something like *inlist* ($cancerRecord.PRIMARY_SITE, "C500, C501, C502, C503, C504, C505, C506, C508, C509") *containsAny* (kcontext, $cancerRecord, "505101,505102,505103,505104,505105,505106,505107,505108") *not inlist *($cancerRecord.PRIMARY_SITE, "C500, C501, C502, C503, C504, C505, C506, C508, C509") *not containsAny *(kcontext, $cancerRecord, "505101,505102,505103,505104,505105,505106,505107,505108") *Please note that inlist and containsAny are valid functions that work. But I am not able to import tham within the constrains.* I not able to locate any documentation in this. Can some one point me to the right documentation. I have been stuck on this for couple of days. Any help is appreciated. Thanks in advance!

Re: [rules-users] DROOLS 5.6.0 Final Decision Table PermGen space OutOfMemoryError

Mark, thanks for responding. Do you have a recommendation as to how much I should increase the perm gen space? Also, is there anything else I can do to run my decision tables more efficiently?

Kie-Spring Issue, not able to created Session as "prototype"

by mattmadhavan

Hello, I have the following kie-spring xml definition to test my custom evaluater. Please note the * type="stateless" scope="prototype"* in the xml configuration. Everytime this session is looked up, I want a new instance of the StatelessKieSession. I am getting the same instance for both the look ups! Looks like the session bean is created as a Singleton even though I specified prototype scope. I really need to create prototype version of my StetelessKieSession on demand ( I am using Camel routes) as I increase the number of JMS clients to process the load. This is a critical feature I really require. Any ideas please? Seems to that kie-spring is not really mature enough! Thanks in advance!

DROOLS 5.6.0 Final Decision Table PermGen space OutOfMemoryError

by Jan Rose

Would like some advice regarding using Decision Tables in DROOLS 5.6.0 Final. We have decision tables with over 12,000 rows. It is a basic 'look-up' table with 3 conditions and 2 actions. The conditions are, for example: Company = X Dept = X Class = X then value = X and log X. When I reduced the number of rows to approx. 500 . .. it works. I have set the max memory in the JVM to 2 gigs. We have tried compiling the decision tables using the spreadsheet compiler as well as the decision table compiler. Below is the error when using the decision table compiler. However, we get the same PermGen space error with the spreadsheet compiler. Obviously, we need to be able to have more than 500 rows in our decision table(s). Any advice would be appreciated.

Drools 6.0.1: Pushing changes back to Workbench GIT using SSH

by dotrc

I am using workbench for managing my rules maven projects within the embedded GIT repository. I am aware that using git:// protocol, I can clone an existing rule repository; I can do this successfully. For authoring rules, I want to use Eclipse (using EGit). I want to push my commits back to the GIT repo. I understand that I'll have to use ssh protocol instead of git for specifying the repo, something like this: ssh://{userName}@localhost:8001/{repoName} When we use a standard GIT repo like stash, it gives us an option to set our public key on the stash server, but I'm not able to find a way to do that with the embedded ssh server within workbench. Hence, I'm not able to authenticate myself and perform a push. We tried creating a private-public key pair using ssh-keygen and put that within c:\users\<username>\.ssh and added the public key to 'authorized_keys(2) (though I know this may not be the right place) and then used the private key as the identity file with ssh client directly from cygwin, again to no avail. Any pointers will be really appreciated. Also, should the username be 'admin' or any other specific one for pushing? Will the existing Windows username work?
