Hello everyone

I'm developing a job with a java component to get total numbers of files in a specific path.

Lines of code are:

File

carpeta

new

File

(

"E:\\Documentación"

);

File[] lista = carpeta.listFiles();

int

cuenta=

;

for

(

int

; i < lista.length; i++)

(lista[i].isFile())

cuenta++;

System.out.println(

"\n Hay "

+ cuenta +

" archivos"

);

The job is

In the code i change to read according tFileList_1 configuration

Regards.

You don't need to hard code on tJava to get the counts of files are found in the specific path. Just use tFileList to get the file list and use the global variable.

tFileList

|onsubjob

tJava

on tJava:

int file_counts=((Integer)globalMap.get("tFileList_1_NB_FILE"));

System.out.println(file_counts);

Thanks for your help

The code line is exactly I need it

If I need to use for other path (aws) it's possible to modify that code line???

Regards.

It does not matter what the location is (local or AWS etc.), as long as you are using the tFileList you can use the Global Variables. The easiest way to do it, is to go to the Outline (bottom left in the Studio) and drag the required variable into your tJava component. In this case you would need the "Number of files - NB_FILE (Flow)".
