Hi,
I am trying to do integration between application and guvnor. I am unable to
build knowledge base using the change_set provided for the package in
Guvnor. Following is the snipet of code i am using. When i try to print
number of packages from knowledgebase, it shows 0.
Can you help me please.
System.out.println("Before rule engine start ");
String
urlstr="http://192.168.2.247:8080/guvnor-5.3.0.Final-jboss-as-5.1/org.drools.guvnor.Guvnor/package/sample/LATEST/ChangeSet.xml";
URL url = new URL(urlstr);
KnowledgeAgentConfiguration aconf =
KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
aconf.setProperty("drools.agent.newInstance", "false");
_kagent = KnowledgeAgentFactory.newKnowledgeAgent( "MyAgent",aconf );
System.out.println("after creating kagent");
_kagent.applyChangeSet(ResourceFactory.newUrlResource(url));
System.out.println("after apply change set");
ResourceChangeScannerConfiguration sconf=
ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
sconf.setProperty("drools.resource.scanner.interval", "30");
ResourceFactory.getResourceChangeScannerService().configure(sconf);
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();
System.out.println("After starting Notification service");
_kagent.applyChangeSet(ResourceFactory.newUrlResource(url));
_kbase = _kagent.getKnowledgeBase();
Collection<KnowledgePackage> kpackages =
_kbase.getKnowledgePackages();
System.out.println("no of packages"+kpackages.size());

If i set cache as following
System.setProperty("drools.resource.urlcache",
"C:\\DDrive\\rule-cache");
changeset xml and another cache file getting generated in
C:\DDrive\rule-cache directory. cache file has rule names which is there in
the package in changeset xml.

I noticed you are calling applyChangeSet() twice. Any reason in why to do
that? I mean, it should work ok, but maybe you have found a bug. Try to
remove one of the invocations.
Regarding the logs, there must be some KnowledgeAgent logs in the console
output of your application. Could you share them?

I'm not an eclipse user, but I'm sure there is something like output log
where for example all your System.out go.

I think we have a duplication problem here :) Are you and
srinivasasanda(a)gmail.com working together? If so, please let's continue

Actually Esetban, I'm working on ChangeSet,so I've taken the snippet of code
from the forums itself.May be that looked like duplicate discussion.But,I'm
facing the problem which I described above.Let me give a hint to get rid of
that.Please

Senthil,
You seem to be having some problem.
Have you tried looking (and adapting) the guvnor-example project that shows
the use of change-sets?
(git clone guvnor-examples) ->
git/droolsjbpm/guvnor/guvnor-examples/src/main/java/org/drools/guvnor/examples/mortgage/client

Thank you Manstis..I'm able to retrieve the packages and rulenames through
ChangeSet.I verified that example(Mortgages).But,When I delete a rule in
guvnor,the change is not getting reflecting in my Java code..I think the
ResourceScanner is unable to start the service.Here is the following
exception I'm getting when i add the below lines
ResourceChangeScannerConfiguration sconf=
ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
sconf.setProperty("drools.resource.scanner.interval", "30");
ResourceFactory.getResourceChangeScannerService().configure(sconf);

Yay, at long last a Java Stack Trace :)
This is a known problem, but one I believe has been fixed for 5.4.0.beta1 -
correct me if I am wrong esteban.

Unfortunately, this is a known issue that remains open:
https://bugzilla.redhat.com/show_bug.cgi?id=733008
What I don't understand is why Drools is trying to use a
ReaderResource instead of a URLResource. Let me check into the source code
to see what I find.

Oh,The bug is still open..Is there any other way to scan the changes that are
being happened in Guvnor console through ChangeSet and Java code.Is there
any other classes like ResourceChangeScanner or any other way to scan
changes in ChangeSet..
Is it possible??
Please let me know
Thanks
