Re: [rules-users] addKnowledgePackages Delay
As I said earlier It *may* or *may not* be relevant in your case. Usually
caching improves performance significantly in drools.
In case of our application it does so by a very significant factor.

Re: [rules-users] addKnowledgePackages Delay
It may look something like this:
Map *knowledgeBaseCacheMap* = new HashMap();
this.knowledgeBase = knowledgeBaseCacheMap.get("");
if(this.knowledgeBase == null){
this.knowledgeBase.addKnowledgePackages(packages);
*knowledgeBaseCacheMap.put("", this.knowledgeBase)*
}
By doing this the packages get added to the knowledgeBase only for the first
time. From second request onwards you get the same knowledgeBase each time
without the need for adding the packages again.
But this is valid only if you are not changing your rules. If your rules are
changing from time to time, you may have to look at caching at more lower
levels.
I am not sure whether this can be helpful in your case but this is often
helpful.

Re: [rules-users] addKnowledgePackages Delay
Hi, Yes, adding packages to knowledgeBase does take some time. You can probably try caching your knowledgeBase. By doing this all, but first, requests should be significantly fast.

Re: [rules-users] Tuples in Agenda Item.
DroolsWorkingMemory is our custom class which contains asserted facts and
other custom objects based on our project requirement. It should not be
confused with "WorkingMemory" of Drools.
For issue 1, I assume that if I overwrite one field in ConcreteType1 to a
different value than that in BaseType, they are treated as diferrent
objects. Consider the xml snapshot of the two objects for eg:
*BaseType* object:
false
2010-04-09T00:00:00
a
0.0
*ConcreteType1* object:
false
2010-04-09T00:00:00
b
0.0
false
so I assume I have two objects BaseType(with value of String as "a") and
ConcreteType1 object (with value of String as "b"). The rule should evaluate
to false on the above assumption.
For issue 2, Sorry If i have misled, my only question was why does the Tuple
inside Agenda Item show only ConcreteType1 and not the BaseType, If both of
them are inserted in WorkingMemory. Doesn't the tuple contain all the
objects inserted in WM.

Re: [rules-users] Tuples in Agenda Item.
Hi,
**
Sorry for not being very clear. Here's the rule which I run:
**
**
*package rr*
*import com.thirdpillar.common.util.DroolsWorkingMemoryimport
com.parentchild.BaseType*
*import com.parentchild.ConcreteType1 *
**
*rule "s"*
*no-loop true *
*salience 99 *
**
*when*
*DroolsWorkingMemory:DroolsWorkingMemory()*
*BaseType:BaseType()*
*ConcreteType1:ConcreteType1()*
*eval (*
*(*
*((BaseType.equals(ConcreteType1)))*
*)*
*)*
*then*
*BaseType.setString("Blah Blah!");*
*end *
where *ConcreteType1 *extends *BaseType. *
**
*Issues:*
1. Even for different values for fields in *ConcreteType1* and *BaseType, *the
rule gets fired.
2. I also do audit for the rules for which i need tuples so that I can
extract the objects out of it and evaluate the expression against Mvel. But
the tuple shows me only the *ConcreteType1* instance not the *BaseType. *Thus
getting wrong audit.

[rules-users] Tuples in Agenda Item.
Hi, I have a doubt regarding tuples. I created a rule using complex types objects. I am comparing two complex type objecs which have parent-child relationship eg. "ParentType.equals(ChildType)". I expect this to follow java rule which allows such comparision. Now when I run the rules with different values for fields in ParentType and ChildType (which means the rule should fail) to my surprise it evals to TRUE. Also upon inspection, the tuple shows me only the ChildType instance not the ParentType. I would appreciate any help on this.
