how to add a custom javascript in oic ?

 

i have a simple JS called sum.js  that adds 2 numbers as below. I go to Integration --. Libraries --> Import and get error

 

Failed to import Library sum.zip. Imported library should contain Library Jar and Metadata XML file only. No directory and other file format is supported.

 

Following is JS

function sum(a,b){

return a+b;

}
