Create new class with custom properties

Hello,
I’m trying to create my own class with my own properties when launching my xwiki but I don’t see how i can do that.

I know how to create a class, i know how to create my custom property, i know how to create class with properties like Date,…(i use velocity scripts with addDateField) but i don’t know how to create my class with my custom properties. If you have any ideas :slight_smile:

Please, Help.
