I've already published all necessary resources to create my report unit and make it work, but I haven't been able to publish jasperreports.properties to WEB-INF/classes directory. All other files where published just fine, and it is definitely the problem with hyphen in folder name. When I am trying to make POST request to ...resources/WEB-INF/classes, I get "WEB-INF" for parameter "folder"."name" is invalid, and it seems that there is nothing I can do about it. Earlier I was creating directories and adding properties using web interface, but via REST API I cannot do that.
It is important, that this file contain only one string:
Maybe, there is another way to add this string to jasperreports.properties, using only REST API, or put it to another place where it will be applied to the server.
