Unable to fire Rules
by hanumesh.m
Hi,
I am inserting message(fileName, fromQ,toQ,transType) to WorkingMemory.
fileName as "ABC-834-test-100.edi"
I am inserting 3 instances of TrasactionVO's to workingmemory as follows:
TransactionVO transVO = new TransactionVO("ABC-834", "ABC.834.EDI",
"ABC.834.XML", "834");
TransactionVO transVO1 = new TransactionVO("XYZ-834", "XYZ.834.EDI",
"XYZ.834.XML", "834");
TransactionVO transVO2 = new TransactionVO("834", "INBOUND.834.EDI",
"INBOUND.834.XML", "834");
In drl, which ever object of TransactionVO matches the fileName of Message,
then update Message's rest of the details with TransactionVO. But the rules
are not getting fired.
Follewed is the testCase and .drl file along with FactObjects.

stopped working. Not able to file Rules..
I am doing wrong anywhere?
Please suggest.

What the.... is happening?
by mmquelo massi
Sorry guys,
but I can't understand why u released 4.0.5 a couple of weeks ago, then u
suddenly released
a brand new "4.0.6" release few days ago (which I promptly downloaded) and
now u put back again
the "4.0.4"....???....
*Why???*
What is the stable one????
Does the svn is working?? Should we build from repository or shouldn't we?
Looking forward to hearing any news on this matter....
Thank you anyway.
Bye.

Does anyone know the answer to this ?
by Saleem Lakhani
Hi,
Can I keep two instances of the same class in working memory? I guess
'Yes'.
If yes then how do I access each instance separately in DSL?
I am doing this: workingMemory.assertObject(personA),
workingMemory.assertObject(personB);
e.g; Person exists = personA:Person()
Thanks

Identify attributes with decision tables
by Jonathan Guéhenneux
hi,
I have no problem for this kind of rule :
rule "Primitive support"
when
$c : Cheese( price < 10 )
then
$c.setPrice( 10 )
end
but I would like to know what is the decision table for this small rule
rule "Primitive support"
when
$c : Cheese( $price : price )
then
$c.setPrice( $price * 2 )
end
I've tried a lot of syntax and I read the section abour the decision table in the manual but ididnt find anything.

RCP and Drools
by J Michael Dean
I have continued to try to isolate the problem that I have previously
described, where my RCP application that calls Drools runs properly,
but am unable to Unit test. Can reproduce the problem simply and am
hoping someone can lend some insight.
I started by creating a simple Drools project that had a JUnit 4 test
in it; this runs. It contains two java files and a DRL file. (Shown
at very bottom of this post)
I then created a Hello World RCP application from the Eclipse
templates. I copied the Drools project files (2 Java files and 1 DRL
file) into the same package as my RCP stuff. When I run the test, I
get the following error, which is exactly the same error I have been
getting with my much more complicated project:
java.lang.NullPointerException

[MVEL] Notice: Possible incorrect version of ASM present (3.0
required). Disabling JIT compiler. Reflective Optimizer will be used.
I then removed all the source files relating to the RCP itself, and
the error persists. If I now remove the plugin dependencies from this
project from the build path, the problem goes away and the tests run.
If I add the plugin dependencies back into the project, the error
resumes. Finally, if I make my ORIGINAL Drools project depend on this
second one with the plugin dependencies, the test fails there too. If
I remove the plugin dependencies, the tests run.
The plugin dependencies are:
org.eclipse.ui
org.eclipse.swt
CodeProSWTFragment
org.eclipse.swt.carbon.macosx
org.eclipse.jface
org.eclipse.core.commands
org.eclipse.ui.workbench

what is the current drools release?
by Godmar Back
What's the most current drools release?
There's discussion of 4.0.5 and 4.0.6 in the email below, which dates
from 26-Mar-2008, but
http://labs.jboss.com/drools/downloads.html lists 4.0.4 as having been
released 31-Mar-2008 and does not mention 4.0.5 and 4.0.6.
Thanks.

Rule Compilation - Thread deadlock possibility?
by Krishna Satya
I have a class DroolsRuleLocator that fetches rules from the database,
compiles and hands me back the RuleBase. At this time I have just one rule
file with a bunch of rules in them. I do not experience any issues when I
execute that in a single thread.
But when I load test my application and the client is passing in the request
that requires *lookup and compilation of the same rule source in my server
concurrently but on different threads,* it appears that my application is
dead locked trying to compile the rules.
Relevant Rule compilation code:
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
try {
// Rule is a simple java bean containing the rule text.
for (Rule rule : rules) {
// ruleDefinition will contain the contents of the drl
source.
String ruleDefinition = rule.getRuleText();
PackageBuilder builder = new PackageBuilder();
// Parse and compile in one step
builder.addPackageFromDrl(new StringReader(ruleDefinition));
if (builder.hasErrors()) {
throw new RuntimeException("Unable to compile rule
definition: "+ rule.getName());
}
// Get the compiled package (which is serializable)
Package pkg = builder.getPackage();
// Add the package to the created rulebase (deploy the rule
package).
ruleBase.addPackage(pkg);
}
}
Remote attaching to the tomcat server and suspending the hanging threads
shows the following trace.

Can someone clarify if this dead lock scenario is a possibility. Currently
I am sychronizing on the method that compiles and returns the RuleBase to
avoid this situation.
Thanks.
