Yes, those who want to play with Groovy and Ebean can have a go.

This code is in HEAD now.

//SCALA bean ... and object/singleton
package org.stest

import javax.persistence._
import scala.reflect._
import com.avaje.ebean.annotation._
import com.avaje.ebean._

@Entity
@Table{val name="f_forum"}
class Person {

  @Id 
  //@BeanProperty
  var id:Int = 0
  
  //var isSomething:Boolean = false
  
  //@BeanProperty
  @Column{val name="title"}
  var name:String = null  
  
  //@BeanProperty
  @OneToMany{val targetEntity = classOf[Topic], val cascade = Array(CascadeType.ALL)}
  var topics: java.util.List[Topic] = null
}

object Person {
  var s = Ebean.getServer(null);
  def find(id:Int):Person = {
    return s.find(classOf[Person], id)
  }
}

//SCALA application using Ebean 
// ... excuse my scala as I'm a complete beginner :) 
package org.stest

import com.avaje.ebean._

object TestMain extends Application {
    
    // find person 1
    var p = Person.find(1);

    println("got "+p)
    
    var t = p.topics
    var sz = t.size
    
  println("done")
}

So the support for Scala beans is in HEAD too.

NB: There is a scala bug that has just been fixed ... where the generic parameter type of a List/Set/Map is not compiled into the .class. This is why the scala Person var topics has to currently have an explicit val targetEntity = classOf[Topic].

Enjoy playing with Scala!!!

I think there is probably a lot of things that could be done to for example give Ebean a more Scala like API ... or make use of Groovy features...

So this is the beginning and if you have ideas/thoughts I'm keen to hear them.

Thanks, Rob.

This example has a better generic DAO
