Re: How to Use Custom Bean in Freemarker

You just put that Users (sic) object into the data model, and then
access its properties like:

  ${users.name}

This works with the default wrapper too, since that extends
BeansWrapper. (Although I would avoid the default wrapper in new
projects, and just use pure BeansWrapper... but that's another story.)
