Retrieving GlobalVar setted in a tSetGlobalVar

Anonymous — Sat, 16 Nov 2024 13:36:26 GMT

Hi,
I try to understand how the tSetGlobalVar works.
I've created a job for testing (see fig1), with
- a tFileInputProperties reading a properties file with 2 couple (key, value) : "chargement.vip.mode=load-after" and "chargement.vip.date=25-11-2009"
- a tSetGlobal var using the main row to set 2 var in the globalMap
- a tJava that prints to 2 globalMap var in the console

When i see the generated code for the tSetGlobal, i can see that :
globalMap.put(row6.key, row6.value);
So in the tJava, i try to retrieve the value i put :
System.out.println("Mode chargement -test : "+(String) globalMap.get("chargement.vip.mode"));

Then i execute : the value displayed is null !!
I tried to connect the tSetGlobalVar to a tLogRow, and when i do that the console displays :
chargement.vip.mode|load-after
chargement.vip.date|25-11-2009
So, how can i do to retrieve in my tJava and in my other component such as the tMap, the values setted in the tSetGlobalVar component ??
I join screenshots.

Thanks in advance !!

Hello

So, how can i do to retrieve in my tJava and in my other component such as the tMap, the values setted in the tSetGlobalVar component ??

On the next subjob, you can get the value of global variable on other component such as tJava, tMap.
for example:
tFileInputDelimited---main-->tSetGlobalVar
|
onSubJobok
|
tJava
on tJava:

System.out.println("Mode chargement -test : "+(String) globalMap.get("chargement.vip.mode"));

Best regards
