LeanFT 14.03 - How to launch AUT using only filename and working directory .

I am using LeanFT 14.03. I want to launch the AUT using filename and working directory without the use of arguements . But the examples mentioned in the LeanFT help does not have that . So any help regarding this will be appreciated . I want to know how the autConfig.json and the actual Java code looks like. 

 

Thank You
