major errors with drools
by Fnu Mahalakshmi
Hi,
I just installed plugin for smooks.
It ended up crashing my other data.
I now do not seem to even be able to resolve org.drools.RuleBase.
I am unable to understand why.
Everything is installed just right.
Please help!!

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.
M

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
M

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.

Re: [rules-users] deleting records in rules
by Fnu Mahalakshmi
Hi ,
Thanks so much.
I ended up doing this:
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" ) )
$b : B()
then
list.addAll($list);
end
It seems to be getting populated with values.
How can I directly write these values to my output file??
I am not sure about working with global lists as yet and have never worked with it.. Please help.
Thank you.
M

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.
Best,

Flow persistence
by Rob Collins
We are using version 5.1.0.M1. We have long-running processes (flows). They are long-running because we have work item nodes that involve the user of our application to do something. We are in the development cycle of our product and everything is going well. I am trying to configure persistence and running into some issues.
I am to the point where our basic unit tests appear to be running fine with persistence enabled both in the container (tomcat6) and in our unit testing environment (ServletUnit).
We have unit tests that run the same test in multiple threads in parallel (the idea is to try to expose thread safety issues), and these tests always fail. At the end of this message, I have pasted a few of the different stack traces I have seen.
I expect that I have done something silly in the configuration, and I could use some help in finding it. I am not sure if the problem is my configuration of JPA, Hibernate, the DataSource, or if it is an interaction between what Drools is expecting and the details of my configuration.
Thanks,
Rob Collins

Re: [rules-users] deleting records using rules
by Fnu Mahalakshmi
Hi,
Are you suggesting to maintain a list of B values in A?
Like A { list<B>();}
// inside my A
And then to populate the list and iterate through that list??
Is that not too much extra data storing?
Thanks
M

If B has a getA() method, you could do something like this:
rule "XX"
when
$list: List(size > 0) from collect B(a.name = "x")
then
someGlobalList.addAll($list);
end
best,
