Multiple inputs from tMap to tJavaRow

JayQueue — Fri, 15 Nov 2024 23:12:48 GMT

Hello,

I can send 2 types of JSONs but the send Java code is the same for both.

To create the different JSONs I use a tMap with an expression filter. But the tJavaRow only accepts 1 input.

I want both JSON to use the Post2MAGDA tJavaRow, if it's possible.

What is the best practice here?

Thanks,

Jonathan

Once the path is split into 2 different routes, you cannot merge them within the same Subjob (without using some code that is). There are many reasons for this.

Your options here are to ....

Repeat the Post2MAGDA tJavaRow component (probably not the most elegant way of doing this)
Use tHashOutput components to collect the data into memory after your tMap, then in another SubJob following the above, read that data (combined) from a tHashInput component and process it using the Post2MAGDA config you have above

@Richard Hall Thank you, I'll start working on it.

It's a small change of mind coming from FME:)
