[rules-users] RE:[ rules-users] Rule engine is worth?

Hi, I have a question. After gone through several rule engines and rule engine documents i learned the capability of rule engine is very good interms of giving coding/changing rules to business analyst.he able to modify the rule without the help of technical person. But the reality is not so. i belevie none of the rule engine including Drools reaching that level. For example to add a simple rule you need a technical person help. what benefits rule engine put in a big project. i don't want thoretical explanation. please let me know any real advantage lies there in implementing rule engine. Beside portability is absolutely not possible(despite being RULEML is defined). If it is not reached that level how it gonna be fit into SOA Thanks and Regs, Basha ________________________________ From: rules-users-bounces(a)lists.jboss.org on behalf of rules-users-request(a)lists.jboss.org Sent: Thu 6/7/2007 11:27 AM To: rules-users(a)lists.jboss.org Subject: rules-users Digest, Vol 7, Issue 13 Send rules-users mailing list submissions to rules-users(a)lists.jboss.org To subscribe or unsubscribe via the World Wide Web, visit https://lists.jboss.org/mailman/listinfo/rules-users or, via email, send a message with subject or body 'help' to rules-users-request(a)lists.jboss.org You can reach the person managing the list at rules-users-owner(a)lists.jboss.org When replying, please edit your Subject line so it is more specific than "Re: Contents of rules-users digest..."

Please also import the SupplierView class in the rules drl file.

We have someone working on unified belief system at the moment, that should allow fuzzy logic, and others, to be integrated. This system will be an integrated extension of the Rete network.

The problem is somewhat inconveniant, (sorry about that) and is already fixed and will be released shortly with a few other bug fixes (it's in version 0.2, so a couple of bugs, unfortunately, exist). This is probably the reason it doesn't work on your Mac. Since we do not have any mac computers available to us (so it is kind of a bigger problem than originaly assessed) we cannot test it whether the fix works on macs or not :( In the meantime please try some alternate fix (e.g. moving the app to another directory). P.S. Thanks for the bug notice ;) On 6/6/07, Fernando Meyer <fmcamargo(a)gmail.com&gt; wrote: > > I got a verbose stacked-error trying to run on mac, > WARN 06 06 2007 17:18:53 [org.hibernate.util.JDBCExceptionReporter:71] - > SQL Error: -33, SQLState: S1000 > ERROR 06 06 2007 17:18:53 [org.hibernate.util.JDBCExceptionReporter:72] - > Access is denied > WARN 06 06 2007 17:18:53 [org.hibernate.cfg.SettingsFactory:109] - Could > not obtain connection metadata > java.sql.SQLException: Access is denied > > basically an permission or missing database error thing, do I need to > configure any native database to use with? > > Fernando Meyer > fmcamargo(a)gmail.com > GPG: 5A6D 3374 B055 A513 9A02 A03B 3DB3 7485 D804 DDFB > > > On Jun 6, 2007, at 6:44 AM, Marko Frankovic wrote: > > Greetings! > > Having difficulties in writing rules?

My challenge is that I am placing into Working Memory a List of Message objects. A Message contains an Order, and Order contains a List of Line Items, a Line Item contains a Catalog, a Catalog contains a PriceCode, and a PriceCode contains a value. I'm trying to create rules that will identify the negative cases. My rules are designed to find Orders, contained within each Message, that should not be Released. If any rule finds a match the Order is no longer eligible for Release and the Message will be updated appropriately. I've had some success with some of the rules I've defined but now I'm getting into the more complex ones and they are giving me some challenges when I need to work with Lists. The following rule compiles and executes correctly but is not complete. rule "Is Academic or Not For Resale" when $msg : Message( state == MessageState.RELEASING ) $order : RequestOrder( requestStatus == RequestStatus.ACCEPT ) from $msg.order $itemList : List( ) from $order.lineItems then System.out.println("Rule Name: " + drools.getRule().getName()); end So this rule compiles and it does print the message so I know that things are working. But now my challenge is to test the PriceCode value contained in each LineItems Catalog? Message -> Order -> LineItems -> Catalog -> PriceCode -> value Should I load all the Order and Line Item objects up into working memory or can I express what I want in a rule without having to do that? Thanks for taking the time to help me with this. ------------------------------ Message: 5 Date: Thu, 07 Jun 2007 00:59:14 +0100 From: Mark Proctor <mproctor(a)codehaus.org&gt; Subject: Re: [rules-users] working with deep object graph To: Rules Users List <rules-users(a)lists.jboss.org&gt; Message-ID: <46674A52.2050905(a)codehaus.org&gt; Content-Type: text/plain; charset=ISO-8859-1; format=flowed Express your data relationally and assert individual objects. Using 'from' to traverse deep object graphs really is for legacy pojo support. If you do that you'll have no problem solving problems like this, look at Conways Game of Life to see how to exploit this relational approach to solving problems. Later we will alow 'collect' and 'from' to be chained together, which will allow this for legacy deep graph pojo support.

" My application contains a GUI for building rules which 'll be converted into some format - .drl or xml - which is understandable to Drools, and saved in database.
