Hi

I'm using Talend to manage flow that call Java api. I use TjavaFlex and write java routine to wrap the java api all is fine.

My problem I've an api that receive a List<String> as parameter and return back a String array.
like  String[] call(List<String> data)

In my flow I get the data from 1 column and I need to build a bulk of 5000 string put this into a list an call the API, the API return back String[] this string array need to continue the flow. Of course I need to make this for each 5000 rows.

I've tried to play with Tbuffer but I don't understand how to change 5000 row to a list

I don't know also how to reenter into the flow the string array that I get back from the API

Please help
