Hi
You can't get the value of global variables in Context views. If you want to specify value to context variable, do it on a tJava after tFlowToIterate. eg:
tFileInputDelimited--main--tFlowToterate--iterate--tJava--oncomponentok--tRunJob
on tJava:
context.p_DT_FR=(String)globalMap.get("row1.p_DT_FR")
....

the context variables defined in the child job have been assigned values on tRunjob, just print the value on tJava to check if the values are passed correclty, eg:
in the child job:
tJava--oncomponentok--tDBRow_1

on tjava:
System.out.println(context.p_DT_FR);

You have defined context variables in child job, and use these variables in any where. Don't need to define the global variables again. Print the value of context variable.
on tjava:
System.out.println(context.p_DT_FR);

@shong , thanks for your reply....

tJAVA ...

Still Parameter value is null...

The same result is if delete and create a new job. Why continue to return null?

Can you change the code of tJava to:
System.out.println(context.p_DT_FR);
