Tjava unable to populate value of previous component

Anonymous — Sat, 16 Nov 2024 06:17:16 GMT

Hi People,

I am newbie to talend...and was trying out to build a job....

My requirement is

tRowGenerator >> Row1>>tSetGlobalVariable>>row2>>tJava

I have generated one random field called name using TalendData.getname() function. E.g (Aarya)

in tSetGlobalVariable

For Parameter "myKey"

Value " (String)globalMap.get(row1.name)"

In tjava

System.out.println("myKey")

unfortunately I output as myKey and I expect Aarya.

Can some one explain what am I doing wrong?

No need to tRowGenerateor

in tSetGlobalVar , put "myKey" as TalendDataGenerator.getFirstName().

the in tJava

System.out.println((String)globalMap.get("myKey"));

It is quite simple can you show your job .

Did you connect tSetGlobalVat to tJava on OnsubjobOK ?

Can you please give screenshot of your job
