Configuring the tSetGlobalVar component

Double-click the tSetGlobalVar component to
display its Basic settings view.
Click the plus button to add a line in the Variables table, and fill the Key and Value fields with
K1 and 20 respectively.
Then double-click the tJava component to
display its Basic settings view.
In the Code area, type in the following
lines:

String foo = "bar"; String K1; String Result = "The value is:";

String foo = "bar";
String K1;
String Result = "The value is:";

Result = Result + globalMap.get("K1");

Result = Result + globalMap.get("K1");

System.out.println(Result);

System.out.println(Result);

In
this use case, we use the Result variable. To access the
global variable list, press Ctrl + Space bar on
your keyboard and select the relevant global parameter.
