5:05 p.m.
I'm using the example code from the Red Hat Magazine -
http://magazine.redhat.com/2008/08/12/jboss-drools-how-to-tuning-guvnor-
part-1/ - to try to get the sample code to work, but I keep getting the
following error:
Exception in thread "main" java.lang.NullPointerException
at java.util.Properties$LineReader.readLine(Unknown Source)
at java.util.Properties.load0(Unknown Source)
at java.util.Properties.load(Unknown Source)
at
org.drools.agent.RuleAgent.loadFromProperties(RuleAgent.java:299)
at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:256)
at test.GuvnorTest.main(GuvnorTest.java:15)
It appears to be unable to find my 'Guvnor.properties' file, but I have
it in the classpath (I actually have it in several different places on
my C: drive as I tried to figure out why it couldn't find it). Does
anyone have any thoughts on what's wrong here?
I'd appreciate any guidance. It seems like this should be a simple
answer but I haven't been able to figure it out.

Hey John,
have you created a Drools Project in Eclipse? Then put the file in
src/main/java
It will be copied over to the bin directory automatically and then
picked up when running your app.
Cheers,
Jarek

hi all,
I'm trying to do the same example

I created the file Guvnor.properties but I can not log in because I must
enter correct username and password and I do not know how to do that.
I get the following error:

I'm using Guvnor 5.1 and I read that I must modify the file ChangeSet.xml
but I don't understand how.
Can anyone help me?
Thanks

Hello Erika,
take a look at the following mailing list posting, it has the proper XML
format for Drools 5.1:
http://drools-java-rules-engine.46999.n3.nabble.com/BRMS-5-1-change-set-x...
(Note the 'basicAuthentication', 'username' and 'password'
attributes
Best regards!

Hello Lucas,
sorry but I do not know how to change the file. My code is:
KnowledgeAgent ka =
KnowledgeAgentFactory.newKnowledgeAgent("/Guvnor.properties");
ka.applyChangeSet( ResourceFactory.newFileResource("bin/ChangeSet.xml") );
KnowledgeBase kb = ka.getKnowledgeBase();
StatelessKnowledgeSession ks = kb.newStatelessKnowledgeSession();
and my file "ChangeSet.xml" is:
<change-set xmlns='http://drools.org/drools-5.0/change-set'
xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
xs:schemaLocation='http://drools.org/drools-5.0/change-set
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/...
<add
<resource
source='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/prova1/LATEST'
type='PKG' basicAuthentication="enabled" username="admin"
password="admin123" / </add </change-set>
but I think it was wrong because it does not work.. How to tell the program
where the file resides?
