tBRMS and Drools

SncJt — Sat, 16 Nov 2024 05:50:58 GMT

Hi all,

Talend v7.1.

I try to use tBRMS component but I have an issue when I execute it.

I have created everything needed on Drools (an organizational unit, a repository, a project, a Data object and a Guided Rule) and I have deployed it.

My job is just a basic tMssql --> tMap --> tBRMS --> tLog.

When I execute it, I have the following issue :

Job Test_Drools_2 terminé à 08:30 14/05/2019. [Code sortie=1]

I saw that it can be a namespace problem.

Here are the configuration of my tBRMS.

I tried to add xmlns:http://myorganization.myproject with default value set to http://myorganization.myproject but then, the job does not compile.

What am I doing wrong ?

Thanks a lot,

Hello,

We are supposing that you have already checked this related scenario about:TalendHelpCenter:Applying business rules to an input flow to filter relevant data.

Did you click Auto map! to concatenate automatically the columns between the Linker source and Link target?

Best regards

Sabrina

Hi Sabrina,

Thank you for your answer !

Yes I had already checked the scenario.

And I have mapped the column correctly I think (as you can see in attachment).

Best regards

Hi,

I just have tried another time to follow the Talend exemple

But now, I have another situation :

I have only 3 rows that go until the tLogRow, even after several seconds.

The job does not end.

Do you have any ideas of what it could be ?

Thanks !

It seems to stop at the first row that do not complain with the business rules.

Is that normal ?

It is solved, I forgot to check the no loop option in Drools Workbench
