Re: [rules-users] So can you automatically upload a POJO JAR Model or not?
by Nicolas Héron
Hi,
Yes it is possible to upload a pojo jar over rest. There were commits in
the 5.5.x branch so you have to compile it yourself.
Contact me in direct if you need more info : nicolas dot heron at pymma dot

Re: [rules-users] unable to resolve method using strict-mode
by Roopa
Hi,
Even I am struck in the same kind of problem.
"RuleBaseTask failed: [Error: unable to resolve method using strict-mode:
com.nph.radar.drools.UpdateQuery.updateQuery(com.nph.radar.rule.operands.Query,
com.nph.radar.rule.operands.AOCCRuleKnobConfig, java.lang.String,
org.apache.log4j.Logger)]"
[Near : {... updateQuery($query, $aoccRuleK ....}]
This is the error I am getting while compiling drl file.
I am calling a method in the when clause.
The same code works fine in eclipse. Error is when I am compiling using ant
script.
Eclipse is doing some settings, that even I got to do in ant script.
I am using drools 5.5.0 and eclipse indigo.
Code :
function String updateQuery(Query querie, AOCCRuleKnobConfig
aoccRuleKnobConfig, String advPgmExclude, Logger log){
}
rule "ExecuteQuery"
//include attributes such as "salience" here...
no-loop true
salience 9
when
//conditions
$aoccRuleKnobConfig : AOCCRuleKnobConfig($commissionThreshold :
commissionThreshold)
$query : Query(name == "Account-Eligibility-Criteria" , $statement :
statement)
Query(name == "AdvisoryProgramExclusion" , $advPgmExclude :
statement)
$order : Order() from
hibernateSession.createSQLQuery(updateQuery($query, $aoccRuleKnobConfig,
$advPgmExclude, log))
.addScalar("id",LongType.INSTANCE)
.addScalar("totalCommission", BigDecimalType.INSTANCE)
.setResultTransformer(Transformers.aliasToBean(com.nph.radar.rule.operands.Order.class)).list();
then
end
Thanks in advance.

Drools desciion tbale - obecjt intialisation
by captainrhino
The following descision table is being used to initialise some question
object before fire all our rules.
<http://drools.46999.n3.nabble.com/file/n4025538/table.gif>
Its creating the following rules butI only want a new question created for
each row with the ability to split the data across multiple columns. I
could probably do this using the data all in one column and use a comma
delimted list but was wondering of there was a way to split the data across
columns for a single rule?
rule "create static questions_18"
salience 65518
when
eval( true )
then
insert(new Question(99,"$2","$3",$4));
insert(new Question(nameA,"$2","$3",$4));
insert(new Question(SELECT,"$2","$3",$4));
insert(new Question(10,"$2","$3",$4));
end
regards and thx for any advice
Graeme

So can you automatically upload a POJO JAR Model or not?
by Mark Bennett
Hi guys,
I'm using 5.5, and I've looked around and around on Google, and although I've seen a few claims that this might work, so far I haven't had any luck. I'm getting various errors, 404 no such page, also "service not available".
I do pass in the authentication header. I'm also making sure to generate Java 1.6 classes, and the UI accepts the JAR without complaint and exposes it in the UI.
I saw one post claiming to upload as an asset, but there was some code change required to Drools/Guvnor to get it to treat it as a model, so that's not an option.
Let me try a few simple questions that might narrow this down:
* Would you expect to use the REST API or the Webdav API to upload?
* What would the URL look like? (I've tried a bunch, looks simple enough online, and I'm able to download the DRLs)
* I downloaded the combo pack of JBoss and Drools/Guvnor 5.5. Is there maybe some config change needed to enable the additional REST or Webdav URLs?
* When you submit a JAR interactively, I know GWT is involved, but does it hand over the request to either the REST or Webdav API? OR does it have some other special entrance into the system, some third way in? And if so, could I use that?
* Would I use a POST or a PUT? The theory seems to be use POST if it's new, or PUT if it's an update, but neither has worked.
* What mime type would you use? The 3 ideas were octet-stream, multipart or java jar (not the exact syntax)
* Would I shove just the bytes of the jar file, or do I need multipart and also include some type of XML file as well?
* Is it OK to just write the raw bytes of the jar, or do I need to encode them?
* Assuming I could upload a JAR, would I then also need to issue some type of "commit", the way the UI does?
* Do you agree that this should be possible to test with curl? (to eliminate Java coding and library differences as the problem)
* Instead of a JAR, is there some other fact model / syntax that I can automatically generate and upload? I get the impression there is, but neither the doc nor the 3 books seem very specific, I haven't seen a full example of this.
* Generally, for dynamic models driven by external systems, what is the "Best Practice" for telling the Guvnor UI about the model? Maybe I'm going about this all wrong?
* Does Drools 6 and the new Guvnor replacement suddenly make this much easier?
I've been looking around and experimenting for about a week now so I'm running out of ideas.
Thanks,
Mark

Can't build 5.5.x with Maven 3.0.4 nor 3.1.0
by Mark Bennett
(sending this to user since I'm not hoping to modify anything, just want to see what's going on, debug, etc)
I'm working through this command on the 5.5.x branch:
droolsjbpm-build-bootstrap/script/mvn-all.sh clean install -DskipTests
I started the day with Maven 3.0.3, but had to upgrade due to this error:
[INFO] --- maven-enforcer-plugin:1.2:enforce (default) @ kie-parent-metadata ---
[WARNING] Rule 1: org.apache.maven.plugins.enforcer.RequireMavenVersion failed with message:
Detected Maven Version: 3.0.3 is not in the allowed range [3.0.4,).
The maven site put me to 3.1.0.
But now I'm getting this error:
Exception in thread "main" java.lang.NoSuchMethodError: org.apache.maven.execution.MavenSession.getRepositorySession()Lorg/sonatype/aether/RepositorySystemSession;
at org.eclipse.tycho.core.maven.utils.PluginRealmHelper.execute(PluginRealmHelper.java:86)
Looking around, it appears Maven 3.1.0 is the problem:
(http://dev.eclipse.org/mhonarc/lists/cdt-dev/msg26246.html)
So… Can't use maven 3.0.4, and can't use 3.1.0…
I guess I could look for maven 3.0.5, but this seems really odd to back port, and make things so fussy on build tools. I haven't seen mvn sensitivity like this on other projects?
BTW, encountered other problems as well running mvn-all.sh against 5.5.x
Links:
Following link from this page: http://www.jboss.org/drools/source-code
To this readme file: https://github.com/droolsjbpm/droolsjbpm-build-bootstrap/blob/master/READ...
But switched to 5.5.x branch: https://github.com/droolsjbpm/droolsjbpm-build-bootstrap/tree/5.5.x

Duplicating template capability in decision table?
by dunnlow
My long lived templates have stopped working (I click the Load Template Data
button and nothing happens) -- I have seen this issue in Jira spanning
several versions (with associated "fixes"). Oh well.
Anyway, I've decided to re-implement using a decision table, which I heard
can duplicate the same functionality. I'm close but can't get past one
issue.
I'm using Drools 5.5, and building the decision table in guvnor.
I am trying (as an Action) to create a new object, assign some of its
variable using a few different columns in the table, and then insert it.
There are at least 5 values that I want to assign, so I don't want to cram
something like "1,123.31,TRUE,2,BROWN" in a single cell -- I want each of
those fields to have their own cell with a header.
The resulting code should look like:
TravelEvent $te = new TravelEvent();
$te.setStartTag({value from "start" column});
$te.setEngTag({value from "end" column});
$te.setOneWay({value from "oneway" column});
.
.
insert($ne);
I've tried putting it all into an action BRL that looks like:
THEN
Insert TravelEvent [$te]:
startTag $start
endTag $end
That creates a column for those values, but no headings. Thus it is only
somewhat better than a comma separated list.
Has anyone tackled this issue before?
Thanks for any thoughts,
-J

guvnor converting descision tables
by captainrhino
<http://drools.46999.n3.nabble.com/file/n4025559/table2.gif>
Trying to convert the following xls spreadsheet to descision table using
guvnor. The spreadsheet above works loaded normally through drools runtime
but it would be real nice if the users could update data rows through the
guvnor interface.
I recieve the following error
com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public
abstract org.drools.guvnor.client.rpc.ConversionResult
org.drools.guvnor.client.rpc.AssetService.convertAsset(java.lang.String,java.lang.String)
throws com.google.gwt.user.client.rpc.SerializationException' threw an
unexpected exception:
org.drools.template.parser.DecisionTableParseException: Unexpected content
"eval( true )" in cell B15, leave this cell blank
Is there anything obviously wrong with what I am trying to do? I have
removed cell b15 but that starts a catalogue of other errors...
Any suggestions most welcome....
regards&thanks in advance
Graeme
