Re: [rules-users] Problem with Banking Tutorial
Hi all,
thanks a lot for your helpful answers.
I'm looking forward to the update to 5.6.0. Is the mentioned time horizon
(a few days) still realistic? I.e. could you recommend me to pause the
evaluation of drools, instead of downgrading to 5.4.0?
We consider to use drools in a larger project, and I have to
decide whether I recommend drools, or prefer a simpler design developed
from scratch. As far it's an fact that I cannot recommend drools 5.5.0.
What version is reasonable to use for further evaluation?
Stefan

Not putting out warnings when some release is known to be broken is a
rather dark spot on the gloss of Drools. I have urged this before,
mainly because
not warning users is a primary cause for them wasting time and effort.
Keep carping...

Is it better to use an older version?

There are a lot of fixes in the 5.x master. Anyone verified their bugs
against this? I suspect this is fixed in that.

Mark has promised a fix for 3 months ago, but of course 5.5.0 remains
broken.

Hi, thank you for your response.
I'm using the latest stable release of Drools 5.5.0 final.
Eclipse is Juno Service Release 2.
Can you confirm, that the order 1,2,3 is the expected result?
If this is a known bug, is there some kind of jira or bugzilla numer
assigned to it?

IIRC, this was a bug one or two minor versions ago. What version are
you
using?

Hello,
I have a problem with the banking tutorial number 3, which is part
of
the
examples of drools expert.
It simply adds some Numbers as facts, and retracts them in an
increasing
order.
It is very short, therefore I post the whole Code:
BankingExample3.java
_
package org.drools.tutorials.banking;
public class BankingExample3 {
public static void main(String[] args) {
Number[] numbers = new Number[] {wrap(3), wrap(1), wrap(4),
wrap(1), wrap(5)};
new RuleRunner().runRules( new String[] { Example3.drl },
numbers );
}
private static Integer wrap(int i) {
return new Integer(i);
}
}

Example3.drl:

[rules-users] Problem migrating from newClassPathResource to newUrlResource
hi, I was recently trying to create a kbase using UrlResource instead of using changeset.xml. So, I wrote the following code : KnowledgeAgentConfiguration kaconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration(); kaconf.setProperty( drools.agent.scanDirectories, false ); KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent( test agent, kaconf ); UrlResource urlResource = (UrlResource) ResourceFactory.newUrlResource(http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/Goal%20Creation%20Charges/LATEST/ChangeSet.xml;); urlResource.setResourceType(ResourceType.PKG); urlResource.setBasicAuthentication(enabled); urlResource.setUsername(admin); urlResource.setPassword(admin); kagent.applyChangeSet(urlResource); kbase=kagent.getKnowledgeBase(); But, to my disappointment this code kept giving me the following error : Server returned HTTP response code: 401 for URL: http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/Goal%20Creation%20Charges/LATEST The changeset which i was using with the follwing code is attached for reference : kagent.applyChangeSet(ResourceFactor.newClassPathResource(drools/resource/changeset.xml)); changeset.xml http://drools.46999.n3.nabble.com/file/n4023490/changeset.xml Regards, Abhinay -- View this message in context: http://drools.46999.n3.nabble.com/Problem-migrating-from-newClassPathResource-to-newUrlResource-tp4023490.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Problem with Banking Tutorial
It is still realistic.. the team is preparing a beta release of 6.x.
When that is done, I hope they will focus on finalizing 5.x..
I am waiting for 5.6.Final myself :)
You may have answered this question before.. could you give a try at
5.5.1-SNAPSHOT?
Thanks for your patience
