Hi Team,
I designed a simple process like as below. here we have two user tasks. each task has frame with some fields.

I am using this process in spring framework. i started the process by using
runtimeService.startProcessInstanceByKey("additionJavaExample");
at start event.
In my spring controller, display the page for user inputs ( taking two numbers for addition ) when the process started. after getting inputs for first user task, how can i pass those values to that?
I am new to activiti framework here please help me out this.
