Re: [rules-users] eval
you're right, but this was just an example for possible functions. In
reality i don't use equal methods here ...
Thanks

This is a bug in the DSL engine. May I ask you please to submit a JIRA
for it?
Meanwhile, I advise you to avoid eval, since it is more performant and
more clear to use regular constraints. The following grammar entries are
equivalent to yours, but much more performant:
[when]- Title equals {value}=title == {value}
[when]- Event equals {value}=id == {value}

Hi,
given the following DSL
[when]of type Item=Item()
[when]- Title equals {value}=eval(title.isEqual({value})
[when]- Event equals {value}=eval(id.isEqual({value})
[then]Log : {message}= System.out.println({message});
the dslr File:
expander Test.dsl
rule Your First Rule
when
$p : of type Item
- Title equals test
- Event equals test
then
#actions
end
resolves to (could be seen in the drl viewer)
rule Your First Rule
when
$p :Item( eval( title.isEqual(test,
eval(id.isEqual(test) ) )
then
#actions
end
so this of course does not work because of the brackets in eval
How could i solve this problem? I need the two different eval
conditions, and sometimes they have to be combined.
Thanks
Markus

Re: [rules-users] Problem in using genrics with drools4.0.1.
Drools, and probably the underlying MVEL that the 'from' uses, has no
understanding of Generics, so I expect thats your problem.

HI ALL,
I am using drool 4.0.1 in my project.
I am facing problem in using generics feature of jdk1.5.
My objective is to perform validation on the basis of data type of variable.
for storing values of variable i have one Attribute Class it contains getter
setter for values of attribute and attributeId which is a string but value
of attribute is of deferent type so i am thinking to use generics here.
public class AttributeT {
public String qualifiedName;
public T newValue;
public T oldValue;
public String getQualifiedName() {
return qualifiedName;
}
public void setQualifiedName(String qualifiedName) {
this.qualifiedName = qualifiedName;
}
public T getNewValue() {
return (T)newValue;
}
public void setNewValue(T newValue) {
this.newValue = newValue;
}
public T getOldValue() {
return oldValue;
}
public void setOldValue(T oldValue) {
this.oldValue = oldValue;
}
}
my rule for date comparison looks like:
//Date Comparison.
rule W250.1 DateComparison
when
$dto : DataProvider()
Attribute(newValue 29-Oct-2007) from $dto.getValue(W250.1)
then
System.out.println (Error in Date check \t);
end
DataProvider class it is responsible to give instance of attribute
corresponding to attributeId:
public class DataProvider {
HashMapString,Attribute fieldMap=new HashMapString, Attribute();
public DataProvider() {
populateMap();
}
public Attribute getValue(String qualifiedName){
Attribute attribute = fieldMap.get(qualifiedName);
return attribute;
}
public void populateMap(){
AttributeDate attribute = new AttributeDate();
SimpleDateFormat format = new SimpleDateFormat(dd-MMM-);
Date date;
try {
date = format.parse(27-Oct-2007);
attribute.setQualifiedName(W250.1);
attribute.setOldValue(date);
attribute.setNewValue(date);
fieldMap.put(attribute.getQualifiedName(),attribute);
}
catch (ParseException e) {
e.printStackTrace();
}
}
}
in this case i am getting exception:
Exception in thread main java.lang.ClassCastException: java.lang.String
when i am not using generics this rule is working fine.
but in this case how should i perform validation depending upon data type of
attribute.
can you please help me in solving this problem.
Thanks,
Gaurav Joshi

RE: [rules-users] RE: RE: rules precompilation
Ekke,
Thanks a lot! It worked just fine...
The other missing point is that after deserializing the PackageBuilder
should be buit as in your example :
builder = new PackageBuilder((Package)ois.readObject());
and later on from that isnatcne should be retrieved the Package inctance
by doing:
package = buider.getPackage();
as otherwise this code was failing:
package = (Package)ois.readObject(); // FAILES, subsequent use
of package produces class not found exception when inserting objects.
Mark,
Think this should be documented somewhere in manual... under IMPORTANT
section... by the way, IMHO that section should be more visible from
what is used currently in manual... - thin italic font, how about bold
red?
Thanks to all,
-Sergey

Ekke,
Thanks a lot! It worked just fine...
The other missing point is that after deserializing the PackageBuilder
should be buit as in your example :
builder = new PackageBuilder((Package)ois.readObject());
and later on from that isnatcne should be retrieved the Package inctance
by doing:
package = buider.getPackage();
as otherwise this code was failing:
package = (Package)ois.readObject(); // FAILES, subsequent use
of package produces class not found exception when inserting objects.
Mark,
Think this should be documented somewhere in manual... under IMPORTANT
section... by the way, IMHO that section should be more visible from
what is used currently in manual... - thin italic font, how about bold
red?
You should be able to serialise a Package without having to first add it
to PackageBuilder, we have numerous tests for this.
Thanks to all,

Sergey,
of course Mark is right - you shouldn't use readExternal and the default
constructor.
this was my fault from an earlier mail.
please try something like this:
// EXPORT
...
FileOutputStream fos .
...
ObjectOutputStream oos = null;
try {
oos = new ObjectOutputStream(fos);
oos.writeObject(builder.getPackage());
oos.close();
} catch (final IOException e) {
... your code
}
...
// IMPORT
FileInputStream fis...
...
ObjectInputStream ois = null;
try {
ois = new ObjectInputStream(fis);
builder = new
PackageBuilder((Package)ois.readObject());
ois.close();
} catch (final IOException e) {
...your code...;
} catch (final ClassNotFoundException e) {
...your code...;
}
now your imported package should work like the exported

Ekke,
Started using 4.0.2, but getting same error.
This is how I am loading the Package :
this.pkg = new Package();
this.pkg.readExternal(ois);
Does that look right to you?

sergey,
just tried it:
exported a package with rules as stream
(using the writeExternal() from Package)
then in another run I created new RuleBase, added new Package,
then import the rules into this empty Package (using the
readExternal()
from
Package)
then added some facts, execute the rules,
tested if all rules are there,
tested if the Facts are in workingMemory - all ok
(using snapshot 4.0.2, eclipse 3.3, osx 10.4.10)

Ming, Ekke,
After deserialising the Package back - getting exception when
inserting
facts:
Exception thrown : java.lang.NoClassDefFoundError: XXXShadowProxy
XXX - is my class name
Any ideas?

Sergey,
I am using precompiled rules. Serializing instances of
org.drools.rule.Package works for me.
Thanks,

Folks,
Where can I find information on how to pre-compile rules in 4.0.1?
Thanks,

[rules-users] Re: JBOSS and multiple rule conditions being met
Sheila, You have just violated #4 http://labs.jboss.com/drools/lists.html Mark [EMAIL PROTECTED] wrote: Hi I have been working with JBOSS for a few days now. I cannot say that I am very familiar with it yet. JBOSS rules have been used to validate data in our system. It works fine as long as we care only if a product met any one condition. However, there is now a new requirement which says that the users would like to know all the conditions which the product met setting it to a particular state. To explain with an example: Rule 1 - set status to PENDING if product is HIKING == y Rule 2 - set status to ERROR if product has High Risk Flag == y If a product is only HIKING, then this rule works well. If a product is only HISK RISK then this rule works. However, if a product meets both HIKING and HISK RISK then we would see only one or the other. Code is as given below: WorkingMemory workingMemory = null; workingMemory = getClassValidationRuleBase().newWorkingMemory(); workingMemory.assertObject(classificationValidationData); workingMemory.fireAllRules(); String result = classificationValidationData.getResultValue() How can get the output such that I get a list of all(multiple) the conditions that were met by a product setting it to a particular state. Do you have an example which can show how this can be done. Thanks for your time and help.
