Can i call contextvariable by it value

Anonymous — Thu, 06 Sep 2018 13:21:44 GMT

Can i read context.Variable by its value, lets say

I have 3 context variables in a job

Variable Name-----------------Datatype------------Value

context.Student---------------String----------------Name,Email

context.Name-----------------String----------------Meet

context.Email-------------------String-----------------m@gmail.com

There is only one component in my job 'tJava', and in that i have written following code:

----------------------------------CODE--------------------------------------------------------------------

String student = context.Student;

String[] students = student.split(",");

for ( int i = 0 ; i<students.length;i++)

{

System.out.println(students[i].trim()); //prints Name and Email

System.out.println(context[students[i]]); //want to print the Value of "context.Name" and "context.Email"

}

-----------------------------------tJava throws Error-----------------------------------------

Please help and let me know if more information needed on this.

Regards

What's the background story? Elaborate please? What are you trying to achieve?
Are you looking for a way to read and write global variables? globalMap.put / .get ?

Help us out!?

Achieved my requirements

Instead of writing

System.out.println(context[students[i]].trim());

Got a solution using this :

System.out.println( context.getProperty(students[i]).trims() );
