Hi,
I have a scenario, where for decision table I will inject one object which
holds all facts. Using those facts the decision table has rules. How to
retrieve the child fact from parent in decision table.
sample for this is as follows
Java Code snippet:
DataObject dataObj = new DataObject();
If you take a look at the Verifier it goes through the Drools AST with a
visitor pattern.
It starts by using getting the PackageDescr using DrlParser, this uses Drools
internals so be warned that it might change in the future.
Reader drlReader = new InputStreamReader( stream );
PackageDescr
I have found that any serious Drools application should write and deploy a
consequence exception handler of its own. Perhaps you look at my modest
efforthttp://members.inode.at/w.laun/drools/CustomConsequenceExceptionHandlingHowTo.html-
I think it is still compatible. Any feedback welcome ;-)

Why are you using an extra data object -its far easier if your facts are
actually facts in the working memory.
What you have written as your rules is totally incorrect - you seem to be
trying to write java method calls not rule statements.
My advice is to
a) try writing the same rule as a drl
Since Toni confirms me even before I post this on the list: Using the
Verifier way to get at a column from some spreadsheet is not for the faint
at heart. In addition to what Toni wrote: source code in the Drools AST
corner isn't even commented.

That looks really useful, I didn't know that you could do that!
Any chance you could submit it as a patch to get the default version enhanced
to do that!
Thanks,
Thomas

Hi,
thanks for the reply. I had it already done. Because of its the better
way to interact with guvnor.

The best place to start is the drools documentation
http://www.jboss.org/drools/documentation particularly the expert guide.
This shows both drl and spreadsheet syntax and examples.
You are getting the exception because the first line of the condition should
just be an object restriction eg
There is a blog and a video on this at

Hi Guys,
I want to upgrade drools from 5.1.1 to 5.3.0 CR1, but i found
ResourceChangeScanner could't work.
In version 5.1.1, i wrote this code to get a KnowledgeAgent
KnowledgeAgent kagent =
KnowledgeAgentFactory.newKnowledgeAgent(ReleaseAgent);
Thanks Jervis.
I currently use Guvnor 5.2, and saw that I can use version so I will try to
use them.
- Is there something I will be missing about versions, by using 5.2?
- Do you know when a new version is created? With Snapshots, I could choose
when to create a new one. How about versions?

I want to match a string with the contents of hashmap. The process is like
this.
Let the string is abcd
First it will search for abcd in the map
if found i have to assign it to a variable else i has to remove the last
alphabet (abc) and have to match with hashmap like is the process.

You'll need 2 rules, one for truncating a key that does not match and
another one for handling the match. If you have to handle absolute failure
(not even a matches) you'll need a third rule and a more complex fact for
storing the original and the truncated string.
These 2 rules are untested:
I am inserting a high volume of relatively large objects into a long-running
StatefulKnowledgeSession in Stream mode. I use a rule to start a jbpm
process when each event is received, and the last step retracts the event.
I assumed these were all being garbage collected until my app server

It appears to involve the interaction between 3 rules. For background, this

The difference in that area from 5.2 to 5.3 is that in 5.3 the
interaction between Terminal Nodes and the agenda was refactored into a
listerner pattern . This is required for future features we are working

This is probably enough info to

Good news, I followed your advice and patched drools-core to prevent this,
focusing on removing all listeners:
AbstractWorkingMemory.java, line 1246:
for ( Iterator it = this.__ruleBaseEventListeners.iterator(); it.hasNext();
) {
this.ruleBase.removeEventListener( (RuleBaseEventListener)

I suggest that you open a Jira for this. https://issues.jboss.org/browse/GUVNOR
