Re: [rules-users] How to modify changeset.xml in guvnor
by kenichiwa
Maybe this will clarify things....
For this code:
...
...
...
String urlString =
"http://localhost:9080/drools-guvnor/org.drools.guvnor.Guvnor/package/defa...";
URL url = new URL(urlString);
KnowledgeAgent kagent =
KnowledgeAgentFactory.newKnowledgeAgent("TestAgent");
UrlResource urlResource = (UrlResource)ResourceFactory.newUrlResource(url);
urlResource.setBasicAuthentication("enabled");
urlResource.setUsername("admin");
urlResource.setPassword("");
kagent.applyChangeSet(urlResource);
KnowledgeBase kbase = kagent.getKnowledgeBase();
...
...
...
I am getting this exception:

Problem persisting human tasks
by raic
Hi,
I'm having problems using drools flow persistance with human tasks. I'm
using drools server.
On one hand, I have my test application, which starts a MinaTaskServer for
registering human tasks, and then, the application generates JSON commands
for executing a flow with human tasks on the execution server.
Without using flow persistence, this is working ok, i'm able to retrieve the
pending tasks and completing them without problems.
When I try to configure flow persistence on the execution server, i can
start the process, the tasks are registered ok and drools flow tables are
generated in my database (processinstanceinfo,sessioninfo,workiteminfo...)
with the correct flow information. The problem appears when i retrieve a
pending task, and then, i want to complete it. It seems that the
communication between MinaTaskServer and ExecutionServer is not ok.
The error i'm getting is the following:
[2010:11:327 18:11:661:debug] Message receieved on client :

How to specify relative URL in chagenset.xml file
by Pardeep Ruhil
Hi,
I am getting File Not Found Exception when I try to give relative path of the file.
<resource source='file:../HelloWorld.drl' type='DRL' />
But when I give the complete path, It picks the changeset.xml file.
<resource source='file:C:/Tomcat/webapps/DroolsCheck/HelloWorld.drl' type='DRL' />
Please tell me the syntax for using the relative path for my workflow or rule files.
Thanks & Regards

taskService restart problem (urgent response needed)
by KiranP
i m having 2-3 tasks in my flow the flow works fine in the normal conditions
the tasks are handled by the MinaTaskServer and MinaTaskClient but the
problem is that it uses the command and the call back mechanism using the
map of tasks request (if i m not wrong) hence when the taskservice restarts
all the callback refrence is lost and completing any task wont updated to
the MinaTaskServer (even if the task is available)
can any one hint me who i can achieve trans-restart task completion.....
till today none of my posts got a reply..............i think u r all
busy............if some one gets time plz help....
bcoz now it has become a grave matter.........it urgent...
thanks

Declaring events separately from rules breaks expires
by Samuli Saarinen
Hello,
I have the following situation with Drools 5.1.1: 2 drl files where one
contains an event declaration:
declare Event1
@role(event)
@expires(1s)
end
and other has a simple rule:
rule "Evt1"
when
e: Event1(value == 10)
then
System.out.println(e);
end
And I have the following test which fails:
ses.insert(new Event1(1));
ses.fireAllRules();
clock.advanceTime(2, TimeUnit.SECONDS);
ses.fireAllRules();
assertEquals(ses.getFactCount(), 0L);
The same test passes if the rule and event declaration are on the same
drl file.
Further more if I declare the event in both of the files with different
@expires the one being used is the one that is added first. I was hoping
that the first declaration to be a "default expires" that could be
overwritten later on with a new declaration but it seems that this is
currently not possible.
Cheers,
Samuli

Instructions for upgrading designer.war?
by Han Ming Low
Hi,
I understand that the designer.war is a project by intalio.
When looking at the source for the war at
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/contrib/designer/desi...,
I saw the changes to be made to make it compatible with Drools.
I think I can do some of the steps like
1) changing the web.xml to use tomcat instead of jetty
2) added slf4j library
3) move lib/bpmn2 library to web-inf/lib
4) changes to oryx.js that involve
- commenting out the header
- commenting out the log
- change the repository url from "/designer/uuidRepository?uuid="+ uuid to
"/drools-guvnor/org.drools.guvnor.Guvnor/guvnorAPI?action=load&uuid="+ uuid
However, I'm not sure what is the BPMN2 import/export classes to replace in
WEB-INF/classes
Can someone could tell me which are the classes?
I can also help to update the designer. :)
Thanks.

timer and duration
by OlliSee
Hello there.
I seem to have trouble with the "timer" operator which is documented to have
superseded the "duration" operator for use in the rule body. I might have
something to do with the "not" operator I use in my rule.
Scenario: A is a fact, B is an event
When I write something like this
rule "test"
timer(int: 5s 5s)
when
$a : A()
not (exists B(a == $a))
then
insert(new B($a)); // which means in the new B object: B.a
= $a
end
I expect this rule to fire every 5 seconds if and only if the LHS is true.
I just insert a few A objects at the beginning.
So I expect this rule to fire ONCE, because it will insert the B event which
makes this rule's LHS evaluate to false in the future.
BUT, reality is, this rule fires every 5 seconds, no matter what.
Using the deprecated duration operator with "duration(5s)" instead of the
timer operator, it works as expected.
I assume, that timer works differently compared to duration. So I conclude
that duration should coexist. Or am I missing something here on the usage of
the timer operator?
Thanks in advance.
Oliver

How do I prevent the package registry from being null in my package builder?
by retoy
I just installed Drools and wanted to build a simple RuleFlow.
But When I add any process containing constraints or rules to my
Knowledgebuilder, I'm always getting a NullPointerException, because the
"package registry" seems to be null.
.....

The ruleflow is successfully validated though when i press that button in
eclipse... Can somebody give me a hint what's missing?
Thanks!
