Get global value from child job.

[_AnonymousUser]

I have a child job, in it i defined a global value and changed it. then I want to use globalMap.get("variable") in parent job, talend returns java.lang.NullPointerException.
The job is simply like tRunjob_1(child)-----onSubjobok------tJava_1, i use globalMap.get in tJava1, return this error.

Hi 
The effective range of global variable is limited to the job itself, you can't access a global variable in other job. To define a variable that can be accessible for all job, refer to this article.
