<a href="http://drools.codehaus.org/" target="_top" rel="nofollow">Drools</a> is a Rules Engine implementation based on Charles Forgy's Rete algorithm tailored for the Java language. Adapting Rete to an object-oriented interface allows for more natural expression of business rules with regards to business objects. Drools is written in <b>Java</b>, but able to run on <b>Java</b> and <b>.Net</b>.<br>
<br>
Drools is designed to allow pluggeable language implementations. Currently rules can be written in <b>Java</b>, <b>Python</b> and <b>Groovy</b>. More importantly, Drools provides for Declarative Programming and is flexible enough to match the semantics of your problem domain with Domain Specific Languages (DSL) via XML using a Schema defined for your problem domain. DSLs consist of XML elements and attributes that represent the problem domain.tag:old.nabble.com,2006:post-26578187Drools Flow Scheduler?2009-11-30T08:56:59Z2009-11-30T08:56:59Zstevelaw<br>I would like to begin a rule flow process at 16:00 M-F, and possibly skipping
<br>specific holiday's as well. Is there any built in capability in Drools
<br>Flow, or should I use an external scheduler such as Quartz, etc? I'm
<br>assuming an external scheduler is the recommended way. If so, are there any
<br>examples?
<br><br>Thanks

<br><br> I have the following situation where I am passing a parameter to the .rf file called createUser
<br> how I can define it in the constraint editor of the XOR
<br> I am currently using <b>dialect: java type: code and using return createUser;</b><br> how can this be transformed using <b>dialect: mvel type: rule</b><br><br> I tried eval(createUser) but its not working?? can someone help in this issue??

<br><br><quote author="christian.al"><br>I have the same problem with my application; i've upgrade the Drools runtime to the last snapshot release but the problem persists on my app. Also i've used the main.rf and sub.rf with the attached Class, but i have the same NoSuchMethodError exception; so the problem doesn't depends from my app.

<br>>> Hi,
<br>>>
<br>>> As my understanding, drools will generate java classes for action of
<br>>> rule flow. It seems that if there are two rule flows, and they are in
<br>>> one package, drools thinks that it's dirty to load generated java
<br>>> class of second package, so drools will reload it.

<br><br>I have the following problem:
<br>1- I am uploading a rule file into the guvnor the file can be uploaded successfully
<br>2- When I go to the default package and I press save and validate there is no error and all is fine till here
<br>3- When I build the package I am having the following exception:
<br> <i> Rule Compilation Error the decleraed package "" doesnt match the expected
<br> and unable to generate rule invoker</i><br><br>After tracing it I find that it is resulting from the following:
<br>I have in my Rule Flow that is being uploaded a split in the split there is the following
<br><br> <split id="5" name="Gateway" x="329" y="160" width="49" height="49" type="2" >
<br> <constraints>
<br> <constraint toNodeId="13" name="End Process" priority="2" type="code" dialect="java" >return endProcess;</constraint>
<br> <constraint toNodeId="3" name="Create User" priority="1" type="code" dialect="java" >return createUser;</constraint>
<br> </constraints>
<br> </split>
<br><br>If I removed the <b>type="code" </b> from the constraint tag the process could be uploaded successfully
<br>BUT I am facing after this an error in the GWT I dont know if it is because I have removed the <b>type="code" </b>
<br><br><br> How I can fix this issue??
<br> Is the problem from the Guvnor or from my Rule Flow file??
<br> Please to help in this issue

<br><br> I am currently using the Drools Flow with the GWT web console and I could
<br>create many rule flow processes using the JBOSS 4.2.3 version.
<br>But what I am concerned about is that there will be problems if I changed
<br>the application server?
<br>Please can you help me and tell me if the Drools Flow and GWT web console
<br>are compatible with the following application servers:
<br><br>1- OC4J
<br>2- Bea Weblogic 9.0
<br>3- IBM Websphere
<br>4- Tomcat 6.0

<br><br>I am using eclipse 3.4 on a linux machine. I mostly work in Java EE
<br>perspective. It was working fine till now. But after I installed
<br>Drools plugin [1], trying to open a Java EE project from Java EE
<br>perspective is making eclipse stuck. I can not even close eclipse once
<br>I click on "Open Project". The progress bar says it is opening the
<br>project. But it is taking eternal. Any possible reason why this can
<br>happen?
<br><br>Thanks in Advance,

<br><br>But you'll have to use activation-group instead, and the 2nd
<br>rule will then have to be modified to compute the full discount (-70)
<br>from the initial value.
<br><br>What happens is that one rule fires, modifies the fact, which will permit the
<br>other rule to fire, even if this other one has fired before. no-loop
<br>merely inhibits
<br>immediate refiring of a rule that modfies the participating facts.

<div> Guvnor is a BRMS,it can manage the rules through Jackrabbit Repository.The default,Guvnor work well with derby database.But i want it work with my database,just like MySQL.</div>
<div>My step is :</div>
<div> 1.Run Guvnor with default,and generate the repository.xml and repository dictionary at JBOSS_HOME\bin dictionary</div>
<div> 2.delete repository dictionary and edit repository.xml,only replace the content in <PersistenceManage> label ,just like this:</div>
<div><font style="BACKGROUND-COLOR: #ffff33"> <PersistenceManager class="org.apache.jackrabbit.core.state.db.SimpleDbPersistenceManager"><br> <param name="driver" value="com.mysql.jdbc.Driver"/><br>

</PersistenceManager></font></div>
<div> 3.install Mysql database,and create the guvnor_db database instance,and copy mysql driver to JBOSS_HOME\server\deploy\lib</div>
<div> 4.Restart the JBoss ,i get the exception:</div>
<div> <font color="#ff0000"> </font><font style="BACKGROUND-COLOR: #ff6666" color="#000000">org.drools.repository.RulesRepositoryException: javax.jcr.RepositoryException: Invalid repository configuration: repository.xml: Replacement not found for ${<a href="http://wsp.name" target="_top" rel="nofollow">wsp.name</a>}.: Replacement not found for ${<a href="http://wsp.name" target="_top" rel="nofollow">wsp.name</a>}.</font></div>

How???2009-11-27T09:23:13Z2009-11-27T09:23:13ZJason Smith-11I think I've solved this. You have to fire the property change event *AFTER* you change the underlying property. As long as session.update() is called *AFTER* the value has changed, things seem to work correctly.
<br><br>Does this sound like a reasonable solution? I think I saw in the documentation (what little I could find on this particular subject) that the property event was triggered before the actual value changed.

<br><br>Here is a twist.
<br><br>If I call "update($fact)" explicitly in the rule, the rule is NOT called twice.
<br><br>Can someone point me to the code used by "update($fact)"? Maybe I can figure out what I did wrong to cause the rule to fire incorrectly a second time.

<br><br>I implemented the following listener for my bean and I am calling .update() directly on the StatefulKnowledgeSession.
<br><br>QUESTION 1: Is there a better way? The old API supported .insert(fact,boolean). The new one does not. I am not finding any documentation that explains the new API (version 5.0.1).
<br><br>QUESTION 2: Why is this calling my rule twice? The rule is getting called twice, and the second time it's called, the entry conditions are invalid! That is, I changed the bean in a way that invalidates the WHEN condition. The rule still gets called twice.
<br><br>How do I even begin to go about troubleshooting this? This same behavior was happening with Drools 4 and the old API as well.
<br><br><br><br> private class InnerPropertyChangeListener implements PropertyChangeListener
<br> {
<br> private final InternalFactHandle factHandle;
<br> private final Object fact;
<br> private final StatefulKnowledgeSession session;
<br><br> public InnerPropertyChangeListener(InternalFactHandle factHandle, Object fact, StatefulKnowledgeSession session)

<br>contains multiple snapshots. When we use Export and Import to
<br>provide updated rules to production environment, all the packages and
<br>snapshots are imported to the production environment.
<br>Is there any way to use Export and Import at package level so that we
<br>can export only the package we want and no other package or snapshot?
<br><br>Any help would be a great help to us..
<br><br>Best Regards,
<br>Chaitanya.

<br><br>TypeDeclaration lastType = null;
<br> try {
<br> // Add the type declarations to the RuleBase
<br> if ( newPkg.getTypeDeclarations() != null ) {
<br> // add type declarations
<br> for ( TypeDeclaration type : newPkg.getTypeDeclarations().values() ) {
<br> lastType = type;
<br> type.setTypeClass( this.rootClassLoader.loadClass( pkg.getName() + "." + type.getTypeName() ) );
<br> }
<br> }
<br> } catch ( ClassNotFoundException e ) {
<br> throw new RuntimeDroolsException( "unable to resolve Type Declaration class '" + lastType.getTypeName() + "'" );
<br> }
<br><br><br>If I debug this, I find that the pkg.getName() + "." + type.getTypeName() is resolved to
<br><br>defaultPackage.Message
<br><br>so, its trying to load a class called "defaultPackage.Message"
<br>which obviously isn't found..
<br><br><br><br><quote author="richarda"><br>Yeah, its in the classpath.. and to be doubly sure just before the code I do a
<br>Message s=new Message();
<br>and that works.. so jvm can find the Message object.

<br>You can use GWT RPC to talk to the Guvnor server. See
<br>trunk\drools-guvnor\src\main\java\org\drools\guvnor\server\ServiceImplementation.java
<br>for details. Most functions that are called from Guvnor GUI are
<br>implemented in this class. If this doesnt work for you, you will need to
<br>somehow expose Guvnor server side functions (ServiceImplementation.java)
<br>by yourself, eg, through a Servlet or through a RESTful service
<br>interface. Unfortunately Guvnor does not have this capability yet,
<br>though there were some talks about implementing such features in the
<br>future. You may want to take a look at Apache CXF [1] or JBOSS RESTEasy
<br>[2] on how to use a JSR-311 implementation to publish Guvnor as Restful
<br>(Atom/Pub) services. Let me know if you have interest to explore this
<br>further, I can provide more information on this.

<div class='shrinkable-quote'><br>> Hello,
<br>>
<br>> Drools is very new to me. So please excuse me if this question sounds too naive.
<br>>
<br>> Basically my requirement is: I have a web based (3-tier j2ee)
<br>> application which is
<br>> deployed in JBoss AS. Now I want to incorporate some business rule
<br>> implementations with this application so that end users, who are not
<br>> very technical, can add/modify the rules according to their need. I
<br>> suppose Drools Guvnor will be the front end and rules repository and
<br>> Drools Expert will be
<br>> the back end for such requirements. Please correct me if I am wrong.
<br>>
<br>> I had gone through the drools documentation. That talks about
<br>> stand-alone application for guvnor itself, but I want to use Guvnor
<br>> inside my existing application itself, preferably by using some Guvnor API.
<br>>
<br>> Can some one please provide some insight on how to do this. Also, I'll
<br>> appreciate if some one can point me to some getting started/best
<br>> practice documents for these stuffs?
<br>>
<br>> Many thanks in advance,

Anyway, I still have a problem and I believe it's more a design thing. Let me try to clarify it.<br><br>I have different types of facts, let's say:<br>
<br>* Types: FactA, FactB, FactC;<br>* A stateful session with rules operating on them;<br>* And a global variable, called output, which is a list of messages generated as consequences of those rules;<br>* From time to time, I get notified that a fact of type FactA changed, then I have to:<br>
- retract all facts of type FactA from my working memory<br> - reload them from the database (with java beans being created)<br> - reinsert them in that stateful session<br><br>Now, let's say FactA(1) indicates a fact of type FactA and id = 1.<br>
<br>- Then, in the beginning, I insert FactA(1) and FactA(2) in my working memory and fire the rules.<br>- I have several rules operating on different types of facts, but I'm interested in one rule in particular which operates against FactA and reads something like:<br>
<br>rule "test non existence"<br>when<br> not FactA( id == 4 )<br>then<br> output.add("there's no FactA id 4");<br><br>- This rule is fired and the message is added to my output object.<br><br>
Later on, I have a notification that a FactA has changed, then I:<br>- retract all FactAs from my working memory<br>- clear all FactA-related messages from my output object<br>- reload FactAs (let's say now I have FactA(1), FactA(3), but NOT FactA(4))<br>
- reinsert them in the WM<br>- fire the rules<br><br>The rule that checks that there's no FactA(4) doesn't refire. All other rules operating against FactA do, and since I had removed all FactA-related messages from my output object, this time I don't get the "there no FactA id 4" message in my output.<br>
<br>It sounds like a situation for a stateless session, but I actually have several different rules, operating on different types of facts and don't want to refire all rules, just because a fact of type A changed.<br>
<br>Maybe I should have an strategy of creating different sets of stateless sessions. I'm not sure. Advice is really welcome!<br><br>Thanks again.<br><br>Leo.<br><br><br><br><br><br><br><br><br><br><br><div class="gmail_quote">

<br> Leonardo, <br><br> First, I believer there is a misconception in your reasoning: creating sessions is supposed to be much much cheaper than retracting all facts. Creating a rulebase is heavier, because it requires compilation, but creating a session is supposed to be very light by design. So, first thing you should do is change that.<br>
<br> Regarding your question, if you insert:<div><br><br>SiteLanguage(language : languageCode)<br> t : SiteSpecialServiceType(type : specialServiceType)<br><br></div> The rule will activate and fire. If you don't, then the rule will not match. That is how it is supposed to work.<br>

Hi Guys,<br><br>I have the following situation while running a stateful session with Drools 4.0.7:<br><br>- I want to test that a fact with a given state doesn't exist;<br>- It works fine<br>- At a certain point I have to retract all facts and reinsert them at the stateful session - some of them actually changed and I don't want to recreate the session b/c it's expensive<br>
- Again the fact that didn't exist when I first created the session still doesn't exist<br><br>** Problem: This time the rule that verified the non-existence is not fired because I didn't insert any fact that would retrigger it.<br>
<br>Rule example:<br><br> rule "022"<br><br> when<br><br> SiteLanguage(language : languageCode)<br> t : SiteSpecialServiceType(type : specialServiceType)<br> not SiteLanguageSpecialServiceType(specialServiceType == type, languageCode == language)<br>
then<br> <<consequence>><br>end<br><br>How could I solve or workaround that?<br><br><br>Thanks in advance,<br>Leo.

<br>it logs each time a new best solution is found.
<br>If you see a null in there, that's the problem.
<br><br>However, that logging guarantee doesn't apply if you hooked in a custom
