Design Component name

root — Sat, 16 Nov 2024 05:36:31 GMT

I have a few tJava components added. They are added with name tJava_1... tJava_n

I have renamed and given them a custom name so its easy for me debug.

I know there is a "currentComponent" variable which allows me to reference this object. Is there anything available which would allow me to reference the custom name of that component?

Thanks.

You can access the "custom name" or label, of any component like:

(String)globalMap.get("componentName__LABEL__");
// e.g., for tJava_1:
(String)globalMap.get("tJava_1__LABEL__");

I am not sure what you mean by the "current" component. If you mean the component that is being executed currently in the flow, I am not sure how you would get that.

@nfz11 Unfortunately, this did not work for me. Do you have any working example you can share? Maybe I am missing something.

Thanks!

I apologize, the example I gave will not work as the __LABEL__ value is not exported to the globalMap. I don't think there is a way to get that value in a Talend job.

It is not a custom name it is an alias. If you look at the underlying code, a component called tJava_1 will always be tJava_1 even if it is given an alias. You will always need to refer to the name.
