About withFields and withBean method in halbuilder-json for use in SCALA

[Lalkhum Sanga]

Hi all,

I was trying to use the above mentioned methods (withFields and withBean methods in halbuilder-json) using Scala, but it is not giving anything back to me.

My code is

val representationFactory: String = (new JsonRepresentationFactory)
      .withFlag(

RepresentationFactory.PRETTY_PRINT)
      .newRepresentation()
      .withLink("self", "/sources/")
      .withBean(Customer("fsfs", "sss")
      .withFields(Customer("fsfs", "sss"))
      .withNamespace("ck", ROOT_URL + "{rel}")
      .withBeanBasedRepresentation("ck:leaves", "/lists/sampleassetid1", (Customer("/heylo", "heylo")))
      .withFieldBasedRepresentation("ck1:woohoo", "wahaha", Customer("/heylo", "heylo"))
      .toString(RepresentationFactory.HAL_JSON)


case class Customer(href: String, label: String)


Can anyone point out if i am missing something about withBean(..) and withFields(..) methods?

Many thanks,
Lalkhum Sanga

Replying on this list as well as the main hal list.

You can use either @JavaBean at the class level, or @BeanProperty at the field level to tell the scala compiler to generate javabean style getters/setters.

There may be reasons you might not want to do that tho for scala purity, so some means of generating a Reprentable instance might be useful ( I'll take a look at how I could maybe automate that using scala macros ).
