Eclipse can't make use of Jsonp in Play/Java app

[Cay Horstmann]

I am trying to make a Jsonp response, but when I use the static method

play.api.libs.Jsonp.jsonp

Eclipse displays

The type scala.Product cannot be resolved. It is indirectly referenced from required .class files

I re-ran

activator eclipse

and restarted Eclipse, but it didn't help. There seems to be no Scala library on the Eclipse build path.

I'd appreciate any hints.

Thanks,

And when I compile with activator compile, I get the equally baffling

cannot find symbol
symbol:   method jsonp(java.lang.String,com.fasterxml.jackson.databind.JsonNode)
location: class play.api.libs.Jsonp

I don't get it--https://www.playframework.com/documentation/2.4.x/api/java/play/libs/Jsonp.html#jsonp-java.lang.String-com.fasterxml.jackson.databind.JsonNode- promises exactly that method.

Never mind--I imported play.api.libs.Jsonp when I should have imported play.libs.Jsonp.
