In this “how to” you will see a tMap functionality that makes it a lot easier to debug tMap errors, especially when you are using a lot of data, columns or converts. Before I knew about this functionality I used to spent a lot of time on solving nullpointer exeptions and all kind of convert errors.
Do you want to add a rowNumber to your output then you really have to read this “how to” and learn how to do it! I needed it to add an order line number to my XML file.
In this “how to” you are going to learn how to build a job that produces a JSON string that can be stored to disk or sent to a REST API, for example. I have used the tJSONDoc components from the Talend Exchange for this “how to” because Talend Open Studio doesn’t provide an easy component
When you want to change the date pattern of your received string and you don’t want to use a date format as an output then use the statement of this “how to”.
