Hi Vincent,<br><br>Thanks for precisions.<br><br>Didn't knew only set/get are used. Get to be careful when i will have 100+ attributes :-)<br><br>Yes i created rueles with guided editor and it's working with my attribute. is there a way to remove "empty", "entrySet", "keySet", "clone",... herited from Map. So i would have only the attribute i have defined?<br>
<br>Ok i will do like this for testing eval($m1 != $m2) ... i have put this in separate line to meke it clearer at the beginning.<br><br>I think i will do your first option, rules will be clearer. <br><br>i have always used drl file instead of package. If i deploy a file.pkg, is there a way to know what's in it? If i deploy something, i just want to be able later to very that all is well what i think if i have a doubt (easy with drl file).<br>
<br>When i try to create my session i have problem with pkg. For know with .drl file i do with that :<br><br>KnowledgeBase knowledgeBase = createKnowledgeBase();<br>StatefulKnowledgeSession session = knowledgeBase.newStatefulKnowledgeSession();<br>
<br>private static KnowledgeBase createKnowledgeBase() {<br> final KnowledgeBuilder builder = KnowledgeBuilderFactory.newKnowledgeBuilder ();<br><br> builder.add(ResourceFactory.newUrlResource("file:///d://basicRule.drl"), ResourceType.DRL);<br>
if (builder.hasErrors()) {<br> throw new RuntimeException(builder.getErrors()<br> .toString());<br> }<br> KnowledgeBase knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase();<br>
knowledgeBase.addKnowledgePackages(builder.getKnowledgePackages());<br><br> return knowledgeBase;<br> }<br><br>If i replace the line :<br>builder.add(ResourceFactory.newUrlResource("file:///d://basicRule.drl"), ResourceType.DRL);<br>
by :<br>builder.add(ResourceFactory.newUrlResource("file:///d://PackageTest1.pkg"), ResourceType.PKG);<br><br>but it's crashing : <br>xception in thread "main" org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java:org.drools.rule.builder.dialect.java.JavaDialectConfiguration'<br>

In the second class you don't need the attributes as members,
because Drools uses get / set methods to deduce them, and anyway you
never use them as they are stored in the map.<br>

That is non-sense. Jars are not linked to a category but to a

1) For the condition Map $m1 different then Map $m2. I

Its a way.<br>
You can also test the id directly in conditions (in Guided editor,
bind the id of the first instance to a var, then compare it in the
second condition.<br>

The same for testing that $m1 timestamp (Long) is befor

So they have to know it exist a method isBefore if not
said by the gui?<br>

Same. Add the test directly in the condition.<br>
Another solution is to use a custom operator (search this mailing

It is MapTest1, because this is the class used .... and drools knows

</div>
</blockquote><div class="im">
You certainly can filter your KB afterwards, but this is not really
an out-of-the-box function. To me you have two options. For both
options, you have only one Guvnor package :<b><br>
<br>
First option</b> : categories<br>
set categories for your rules as you said<br>
compile by filtering one category, do a snapshot. Redo the same for
other categories (in other snapshots). <br>
Use these 4 snapshots in your code<br>
<br>
<b>Second option </b>: First filtering condition<br>
create a new POJO having only one field to handle the task asked (or
category or group or file or whatever you call that) add a condition
to all your rules testing this fact according to their group (as
described in one of my previous mail)<br>
create a single package (or use DRL) for all your rules.<br>
when calling your rules, insert the suitable POJO according to
tehexec you want.<br>
<br>
The second is my favorite because it is less work to deploy, and
your number of rules are quite small. The second option can be
change to use a RuleFlow instead of a control fact.<br>
