proxy config for change-set schema fetch?
by Allen, Robert R
Hi All:
I'm running drools expert and guvnor on a single machine that runs
behind an authentication-required HTTP proxy to the outside world. I'm
fetching rulesets from the guvnor URL using the KnowledgeAgent. The
loading of each URL takes a consistent 3 minutes and it appears that the
delay may be from trying to fetch the xml schema which does not succeed
because the request must go to jboss thru a proxy. I get these two
messages in the log file:
(null: 1, 290): schema_reference.4: Failed to read schema document
'http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/sr
c/main/resources/change-set-1.0.0.xsd', because 1) could not find the
document; 2) the document could not be read; 3) the root element of the
document is not <xsd:schema>.
(null: 1, 290): cvc-elt.1: Cannot find the declaration of element
'change-set'.
After the delay, the parsing works correctly and the KnowledgeAgent
creates the KnowledgeBase correctly. Here is an example of the change
set being passed to the KnowledgeAgent:
<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
/main/resources/change-set-1.0.0.xsd' > <add> <resource
source='http://localhost:8080/arcotadmin/org.drools.guvnor.Guvnor/packag
e/pkg1/LATEST.drl' type='DRL' basicAuthentication='enabled'
username='usr1' password='123456' /> </add> </change-set>
Questions:
1. Can I tell KnowledgeAgent to use a local file for the schema
and thereby bypass the external lookup altogether? What would the syntax
for that look like?
2. Is there a way to provide proxy information to KnowledgeAgent
or drools expert as a whole that includes authentication credentials?
Thanks,
-Robert

Hi there,
I was wondering if its possible to measure code coverage on test running
against a set of rules.
Thank you

DSL translation handing - what is the most stable version?
by drdaveg
I've built rules using DSL's before and with 5.3 I am seeing Eclipse hang
intermitently during builds. I've seen this in previous versions of DROOLS
so wondered what/where is the most stable version of DROOLS? I downloaded,
but have not yet installed the product version (this is for a lartge US
firm, so buying the product is feasible). They could not accept needing to
kill off processes when they build. The schedule is VERY tight so I am
asking this question while I install the product version (5.2).
The rules, XOM, and DSL are simple, so I think the parser is intermitently
generating some infinitely deep tree during builds.

drools flow - how to crate a human task form?
by gs76pl
hi,
What is the best way of creating some UI for human tasks with an input form?
I've a sample process with a human task that should update some values in
the process. I had a look into API of a task and the only thing i can find
there is 'content' which i'm not really sure about (is it the place where
for instance HTML UI should be created?) Is there any way to create this
form with some additional actions like : claim/fail etc?

Rules Evaluation based on agenda
by Vis
Hi,
We have many agenda-group based rules defined in application and while
firing rules, we set specifc agend group based on different use cases to the
session.
In evaluation phase of rules, it not only evaluate rules related with agenda
set to the session but also other rules which are not belong to the same
agenda which is set to the session.
Now problem here is:
since some time we get error, if a inserted fact is used in other agenda
group and their nested objects are not initialized which are used in
condition, it throws errors and exit.
if Drools could provide filtering capablitiy at evaluation time like wise
AgendaFilter is provided to filter activated rules, it will be great. If
there is any workaround it will be a great help.
Thanks in advance
-V

rule dialect issue in local file stream Vs Guvnor
by domingo
I have one simple rule, just check the boolean attribute of the object and
print the value of the boolean, that simple rule. I am using java as my rule
dialect. I found something interesting while debugging.
1. When i read the drl file from the local file stream I found the
following...
getDialect ::: java
getConsequence :::
my.test.package.name.TestOne.Rule_boolean_test_rule_0DefaultConsequenceInvoker@b3a21684
2. when i read the same drl from the guvnor I found the following...
getDialect ::: mvel
getConsequence ::: org.drools.base.mvel.MVELConsequence@67bc67bc
Here is is my doubt...since i use the same rule file and 'java' as dialect
why the consequence and dialect are diffrence from ocal file stream.
If anyone clear this doubt will be greatly appreciated.
-----
with kind regards,
