RestEasy: Is it possible to post two complexe objects?

Question

I am trying to transport two complexe objects as parameter with RestEasy with @POST annotation.

@POST
@Path("/save")
@Consumes("application/json")
public void save(ComplexeObjectAleph objectAleph, ComplexeObjectBeth objectBeth);

With only one parameter is allright, but with two - I get Exception:

You can't do that. See details: http://stackoverflow.com/questions/5553218/jax-rs-post-multiple-objects — Piotr Kochański, Mar 26 '13 at 22:13

That is possible, but with carefulness.

The two parameters must be annotated with @Form.

@Path("playarea")
public interface PlayareaRsInterface {

    @POST
    @Path("save")
    @Produces(MediaType.APPLICATION_JSON)
    public void save(@Form ComplexeObjectAleph objectAleph, @Form ComplexeObjectBeth objectBeth);

}

and the attributes of the two classes must have @FormParam(...) annotation:

public class ComplexeObjectAleph {

    @FormParam("aleph")
    public String aleph;

}

public class ComplexeObjectBeth {

    @FormParam("beth")
    public String beth;

}

But be careful, the value of @FormParam(...) must be unequal, else RestEasy cannot parse the data correctly. May be that is bug of RestEasy.
