How to define a class of a parameter that is not present in the select?

Question

I got a problem with the Jasper Studio application. I want to make a parameter, but I don't find java.lang.collection in the class select.

What's the solution so that java.lang.collection is in the application

Answer 1

You have 2 options

1. Type the class directly (it's an select, but you can also type)

2. Press the button next to the select it will open a Dialog as shown in image, then type your class and press "OK"

I'm not sure what class java.lang.collection is I guess your are looking for java.util.Collection
