Deploying a Data Mapper Job

willm1 — Sat, 16 Nov 2024 11:40:57 GMT

Hello -
I've created a job that parses a complex XML and maps the output to a CSV file, using Data Mapper in Talend Enterprise 5.4.1. I've tested the map, and the output looks great - works as expected.
Now I want to deploy my job to be able to execute it from Talend DI - as a part of a set of operations. I've exported my job from the Studio using File --> Export --> General --> Archive. I'd like to execute this job from my Talend Job using the Java API (think this is the most straightforward option that does not depend on 3rd party libraries) - http://doc.talend.com/enterprise/talend_data_mapper/3.3/api.php
The documentation talks of examples, but I couldn't find them - got errors when I selected Help --> Cheat Sheets...
Any help in deploying a Data Mapper job would be appreciated.
Thanks.

Thank you, Sabrina... I'll wait to hear back... In the meantime, I'll investigate if this is the right approach - seems to be - https://help.talend.com/search/all?query=tHMap&content-lang=en

I made some progress by following the Scenario 2 on the link in my previous post.
I've configured my job as shown in the attached screenshots. I independently created a map in the Data Mapping perspective. Then I switched to the Integration perspective, created the job as shown and mapped to the map I had created in the Mapping perspective. Unfortunately, it failed with the following error:

Starting job Test004XML at 17:15 17/04/2014.

Hi willm,
I know that it's too late for a response but I think this might help someone facing a similar issue in future.
The reason that you're getting that exception is because of a configuration issue in tHMap component. You're reading a single XML as input and you intend to output a single XML, so change your tHMap component settings like below.
Write Output As Document (single column) instead of Write Output As (Date Integration columns)
Thanks,
