Re: [rules-users] [Knowledge Agent Question
by Mahalakshmi
Hi,
Thanks so much for the info.
So then is there any way to actually add the dslr (created at runtime) files
to be detected by the program??
Because with eclipse we always need to keep refreshing the files everytime
which totally defeats the purpose of using business rules !! Until ofcourse
you have fixed set of rules!
Any other ideas?
Also is there a problem if we add multiple .dslr files to our rule base???
When I do that only the first .dslr files actually executes and the others
dont. I tried creating all the same files as .drl files and it works
perfectly fine.
Any idea why that happens??? I dont get any error stack.
Please help.
Thanks

JBoss password required to connect a PKG via a Agent
by mmquelo massi
Hi everybody,
I am using Guvnor 501M2 on JBoss standalone.
I am accessing the PKG resource from my java code as follows:
ResourceBundle resourceBundle = ResourceBundle.getBundle("guvnoragent");
Properties props = new Properties();
props.setProperty("drools.resource.scanner.interval",
resourceBundle.getString("poll")); ResourceChangeScanner service =
ResourceFactory.getResourceChangeScannerService();
ResourceChangeScannerConfiguration rconf =
service.newResourceChangeScannerConfiguration(props); service.configure(
rconf ); //Agent Conf KnowledgeAgentConfiguration aconf =
KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
aconf.setProperty("drools.agent.scanDirectories",
resourceBundle.getString("scanDir"));
aconf.setProperty("drools.agent.scanResources",
resourceBundle.getString("scanRsc")); BufferedReader bfr=null; try { bfr =
new BufferedReader(new FileReader(new File("......Changeset.xml"))); } catch
(Exception e) { ... } //Agent configurato e con Packages guvnor aggiunti
KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("AgentPOC",
aconf); Resource csReader = ResourceFactory.newReaderResource(bfr);
kagent.applyChangeSet(csReader);<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Here I get the following exception:

*This is why the server is asking Java the JBoss credentials!!!*
How can I pass them?
Should I define them in the changeset.xml?
If it is so where can I fine the XSD file ???? I guess there is a tag or an
attribute like "password" or something
that will contain date that the Agent has to send to the server....
Should I remove the password check from JBoss?
Please let me know.
As far as I know there are other people on the IRC CHAT with the same issue.
Thank you 4 any help u can give me.
Bye,
Massi.

MVEL strict mode -- when, why?
by Barry Kaplan
I have never gotten any of my rules to compile using mvel strict mode. If I
leave the default I get spews of error messages that I can't make any sense
of. For example with:
---
package systeminsights.plugin.core.schedule
rule "foo"
when
eval(true)
then
// noop
end
---
I get messages like
[Error: Failed to compile: 3 compilation error(s):
- (1,21) unqualified type in strict mode for: plugin
- (1,26) unqualified type in strict mode for: core
- (1,35) unqualified type in strict mode for: schedule]
[Near : {... Unknown ....}]
^
[Line: 1, Column: 0]
If I set strict mode to false all is good.
So, what is actually going on with strict mode? And how does one interpret
messages such as the above?

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.

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:

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.
