Use variables from one output in another output after replicate

[JayQueue]

Hello,

Backstory: I'm coming from FME and started using Talend since 4th of October, without a course. So bear with me 😉

Issue:

I'm reading a folder where there are 2 files, an XML and a PDF. The XML contains the metadata from that PDF (both have the same name).

Now I'm uploading that PDF with a tFileFetch but I want to pass the metadata directly with that request. Is that even possible with my job?

What I tried:

1. Changing the order
2. I've been looking into subJobs but I can't seem to figure it out.
3. tSetGlobalVar

Here's my job

Hi @JayQueue,

you can use TSetGlobalVar after the tXMLMAP_1 and change the order of the TReplicate row so the globalvar will be set before you use the tfile fetch

Send me love and kudos

Hello @guenneguez jeremy​ 

I tried that but then the first row is NULL

This is the job:

 

Changed the Main order behind the Replicate.

Did the mapping with tXMLMap_1

Then set the tSetGlobalVar_1:

 

I added a tJavaRow in Main order:2 and Main order:1 with

System.out.println("Value of _documentSubject in Main Order:2");

System.out.println(globalMap.get("_documentSubject"));

My output is

Value of _documentSubject in Main Order:2

null

Value of _documentSubject in Main Order:1

Uitgaande facturen Kotee

Value of _documentSubject in Main Order:2

Uitgaande facturen Kotee

Value of _documentSubject in Main Order:1

Uitgaande facturen fin.dienst

So it's starting with Main Order:2!?

That looks weird.

Sending love and kudos

To make sure the job runs in order, i would suggest you to split the job into different subjobs, eg:

tFileList--tIterateToFlow--tHashOutput

|onsubjobok

tHashInput--main--XML file...

|onsubjobok

tHashInput--main--PDF file...

If you have difficulty to find hash component :

https://help.talend.com/r/iDUwyneSPUgZVyVcWpVlVw/v0SoaRheiWnba9aPAp21gQ

it's for 6.5 doc but it's the same for 7.3

also when you try to get globalVar it's better to specify the type :

System.out.println((String)globalMap.get("_documentSubject"))

[gjeremy1617088143]

and the gloabalvar can't work if it doesn't used in an iteration for all the flow, the problem here is you directly use iteratetoflow so you're no longer in an iteration.

Hello @Shicong Hong​ ,

Thanks for the help.

But I can only choose On Component Ok

Thanks @guenneguez jeremy​ , I found already 🙂

I thought I was in an iteration
