Java ee returns 500 error when returning boolean

I have a java ee application that uses jax-rs. But when i return a boolean in a call that returns json, it gives a 500 error.

    @GET
    @Path("/test")
    @Produces("application/json")
    public boolean test() {
        return true;
    }

The above code will give this generic error message: The server encountered an internal error that prevented it from fulfilling this request.

If i remove the @Produces("application/json") it does work but returns 'text/plain'.

Solution

  • JSON consists of key:value pairs. So you cannot return a simple boolean, because what should be the name of the corresponding key ?

    So either return a Map<String, Boolean> or a boolean[]
