Knowledge Agent Question
by Fnu Mahalakshmi
Hi guys,
In my program I have couple of .brl, .drl and .dslr files which get added to the rulebase.
Now my .brl files get converted to drl files and then have to be added to the rulebase.
After creating my .drl or .dslr file I am using this code to update the resources in my change-set.xml
ResourceChangeScannerConfiguration sconf = ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
sconf.setProperty( "drools.resource.scanner.interval",
"30" ); // set the disk scanning interval to 30s, default is 60s
ResourceFactory.getResourceChangeScannerService().configure( sconf );
ResourceFactory.getResourceChangeNotifierService().start();
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add( ResourceFactory.newClassPathResource( "change-set.xml", getClass()),ResourceType.CHANGE_SET );
if ( kbuilder.hasErrors() ) {
System.err.println( kbuilder.getErrors().toString() );
}
Now as per my understanding:
Since a new .drl file has been just created - the resource notifier will update my change-set.xml file of the change.
Now I need to load this new file to my rulebase along with my dsl file.
kbuilder.add( ResourceFactory.newClassPathResource( "change-set.xml", getClass()),ResourceType.CHANGE_SET );
is adding my new created file to my knowledge pacakage.
How can I specify my dsl file also to be added along with it???
Can you please guide me in the right direction..??
Please help.
Thank you.
M

Problems with OR
by skasab2s
Hello,
we are using Drools Expert. We have a rule which should fire if at least one
of the object attributes are not empty. This is my pattern:
( TblVersichKlinik(versicherung != null, versicherung != " ")
or
(TblVersichKlinik(zusatzversicherung !=null, zusatzversicherung != " ")) )
The problem is the following: when BOTH conditions are fulfilled, the rule
fires twice, so I get redundant results in my final result, and this is not
wanted.
Is there a way to solve the problem? Any ideas ?
Thanks a lot and many regards!

jBPM and Drools Flow
by Hitoshi Ozawa
Hi,
With changes in jBPM team and a new announcement on jBPM 5 being more
compatible with Drools Flow,
would appreciate if someone can tell me the current stance on Drools
Flow. Will the two join or remain
separate.

I also keep getting the following error when I run the program:
Exception in thread "main" java.lang.NoSuchMethodError: org.drools.compiler.PackageBuilder.addKnowledgeResource(Lorg/drools/io/Resource;Lorg/drools/builder/ResourceType;Lorg/drools/builder/ResourceConfiguration;)V

Is my drools-compiler.jar not having the correct information required???? How can I change that??
Can you please guide me in the right direction..??
Please help.
Thank you.

Re: [rules-users] creating and integrating a specific output using drools
by Fnu Mahalakshmi
Hi,
For using queries against the working memory : we do again need a knowledge of which query to fire against the working memory depending on which rule is fired. Also maintain a list of different queries which is ultimately written out to our output file.
Is there any way to determine this in our rule itself??
I could set a variable stating which query to be fired. But again I will be maintaining a lot of global variables then.
Any idea?? Any better solution???
Thanks
M

Rather maintaining global lists have you looked into using queries against the working memory to get out what you need?

creating and integrating a specific output using drools
by Fnu Mahalakshmi
Hi,
I have my basic drools application up and running.
Now I have a very disconnected input file (i.e all data is very diff from each other)
As of now I am loading all the output data in a globallist and writing it to an output file.
Now all the global lists are separate for different data inputs that I provide.
Is there a more efficient way to do this rather than maintaining many global lists ???
Thank you.
