smooks terrible error
by Fnu Mahalakshmi
Hi,
I am trying to work with smooks and have major errors !!! everything is crashing!
My code which I added is:
public void runStatelessRules(String[] rulesFiles,String dslFileName,Collection<Object>al,
String ruleFlowFileName) throws Exception {
KnowledgeBase ruleBase = loadRules(rulesFiles);
StatelessKnowledgeSession workingMemory = ruleBase.newStatelessKnowledgeSession();
Smooks smooks = new Smooks("smooks-config.xml");
DroolsSmooksConfiguration conf = new DroolsSmooksConfiguration("some name",null);
DroolsSmooksStatelessSession smooksSession = new
DroolsSmooksStatelessSession(session,smooks, conf);
javax.xml.transform.Source xmlSource = new StreamSource(getClass().getResourceAsStream("NewFile.xml"));
smooksSession.executeFileter(xmlSource);
workingMemory.execute(al); // what to add to my working memory?????????????
}
This is the basic code which I just incorporated from the book.
I installed smooks plugin for eclipse.
But could not find smooks-config.xml file.
I am not usre of what else I need to incorporate.
Now everything else also seems to be showing error i.e all the code which was working perfectly.
Please help!!! Major disaster.
Thank you
M

specific rules
by Fnu Mahalakshmi
Hi,
Is it possible for us to enhance the way our rule works?
For example:
Using a business rule can I specify to the user: A can have option 1,2,3
And user can set it as A[a] value 'is equal to ' 1 // and you can get output accordingly.
For instance if we could specify a set of drop down options for the user to make rules operation more easier??
Is it possible. I am using a DSL for the normal rules. But not sure how I can specify these specific details before hand.
Can we use or populate global lists in business guided rules??? In the condition part of a rule?? I am able to access it in the action part.
Please help.
Thank you.

Guvnor importing model error
by Mylene
Hi,
I get errors after I import my (JAXB-generated) model in Guvnor.
The original schemas are rather complicated, and thus the generated model
depends heavily on inheritance. Could that be the problem?
The message I get is: Unable to validate package configuration (eg, DSLs,
models) for [my_package]. Suggestion completions may not operate correctly
for graphical editors for this package.
I don't get any completions... (but I guess that is to be expected after
this error)
I'm using drools-5.0-guvnor-standalone, Java 1.6 and JAXB version 2.2.1
Can anyone point me in the right direction?
Thanks

Global Variables and Business rules
by Fnu Mahalakshmi
Hi,
How can I depict global lists in my business rules?
For instance:
rule "populate list for A with required status"
when
$a : A()
$list : ArrayList( size > 0 )
from collect( B( a.name == $a.name, status == "P" ) )
then
requiredList.addAll($list);
end
I want to depict my $list : ArrayList( size > 0 )
from collect( B( a.name == $a.name, status == "P" ) )
with help of business rules.
Any idea how???
Thank you

A real funny thin I wanted to share!
by Fnu Mahalakshmi
Hey guys,
You have all been really helpful and I really wanted to share a funny thing that keeps happening!
It would probably make your day!
I use eclipse for my drools projects. Have everything set up!
Out of the blue when I click 'open perspective' I don't seem to get the 'Guvnor ' option.
Then suddenly it appears again ! This seems to be a repeat process! I have no idea why!
But seems ridiculous! :P :)

Re: [rules-users] pulling data from external database
by Fnu Mahalakshmi
Hi,
Yes. I need facts from the database. I will be query the database using a SOAP call. So I end up getting an XML input file as my fact input.
I am trying to use Smooks framework for this as suggested online. I downloaded the required JBoss Tool for it
But don't seem to be able to find much information on how to implement it.
I just got this snippet of code:
Smooks smooks = new Smooks("smooks-config.xml");
DroolsSmooksConfiguration conf = new DroolsSmooksConfiguration("some name",null);
DroolsSmooksStatelessSession smooksSession = new DroolsSmooksStatelessSession (session,smooks, conf);
javax.xml.transform.Source xmlSource = new StreamSource(getClass().getResourceAsStream("name-of-data
-file.xml"))
smooksSession.executeFileter(xmlSource);
Where do I get my smooks-config.xml file? And if I want to specify multiple input XML files can I just keep invoking this again for passing my input files?
javax.xml.transform.Source xmlSource = new StreamSource(getClass().getResourceAsStream("name-of-data
-file.xml"))
Please guide.Is there any better documentation for this? Or is there a better way to do this?
Thank you.

There is no specific "way" of doing it with drools. You could use JDBC,
Spring, Hibernate, etc. The more important question is what data from a DB
do u need? Facts?

Rules error
by Fnu Mahalakshmi
Hi,
I m trying to do this:
GeneralList and RequiredList are my global lists
rule "populate list for A with required status"
when
$a : A()
$list : ArrayList( size > 0 )
from collect( B( a.name == $a.name, status == "P" ) )
then
requiredList.addAll($list);
end
rule "populate list for A with general status"
when
$a : A()
$list : ArrayList( size > 0 )
from collect( B( a.name == $a.name, status == "U" ) )
then
generalList.addAll($list2);
System.out.println("general list size " +generalList.size());
generalList.removeAll(requiredList);
System.out.println("general list size " +generalList.size());
End
But remove all does not seem to have any effect.
Any idea why????
Plus if I do
when
$a : A()
$list : ArrayList( size > 0 )
from collect( B( a.name == $a.name, status != "U" ) ) // "!=" it just ends up giving me all the values and not what status is
Please help.
Thanks

pulling data from external database
by Fnu Mahalakshmi
Hi,
Could you point me towards some documentation which gives information on how I could pull data from my database with drools??
can I just do it by using JDBC (using this right now)? Is there any other way to it?
Could not find it in the documentation online.
Thank you

Re: [rules-users] deleting records in rules
by Fnu Mahalakshmi
Hi ,
I ended up doing this:
I have the following:
> > A = new A(); A1 = new A()
> > B b1 = new B(A)
> > B b2 = new B(A)
> > B b3 = new B(A1)
> >

ArrayList list = new ArrayList();
workingMemory.setGlobal( "list", list );
To set global list in my working memory
My rule is like this:
rule "Raise priority for A with required name"
when
$a : A()
$list : ArrayList( size > 0 )
from collect( B( a == $a, status == "x" ) )
then
list.addAll($list);
end
my global list is getting populated with values.
But still I end up getting a value for B even if it has a different status.
Eg:
B1 = (A, status = x)
B2 = (A, status = y)
B3 = (A1, status = x)
And I want values where status = x
In my above code I get output as: B1, and B3 whereas my output should be B3 only.
Any hint?? How can I segregate specific values?? I am inputting the $a for exact matching. What more can be done???
Please help.
Thank you.

No. If B class has a reference to A, then *$list: List(size >0) from collect
B(a.name = "x") *will collect all B fact having a.name == "x" into a new
List
You could read the documentation about *from collect *for further
information.
