Re: [json-lib-user] Should static fields of a bean be included in its JSON representation?

[Andres A. <aal...@ya...>]

Florian,=0AThe static "property" is not picked up by PropertyDescriptors, b=
ecause=0Aproperties belong to a bean (an instance), in your case the static=
=0Aproperty belongs to a class (a bean type). It may seem like a good idea=
=0Aat first to support static properties but let's look at the following ex=
ample,=0Aa basic implementation of the Singleton pattern:=0A=0Aclass MySing=
letonBean {=0A   private static MyBean instance =3D new MyBean();=0A   priv=
ate MyBean(){ ... }=0A   public static MyBean getInstance(){ return instanc=
e; }=0A   ...=0A}=0A=0AIn order to avoid the 'instance' property to be seri=
alized (causing an endless=0Aloop) you'll have to register it in the exclus=
ions, the same will happen with all=0Aother 'property-like' static methods =
that you wish to leave out of the serialization=0Aprocess. Depending on the=
 available static methods of a bean, you may end=0Awith lost of exclusions.=

following question might have an obvious answer, but=0AI'd like to ask it a=
nyway. Suppose I have this Java Bean:=0A=0Apublic class MyBean implements j=
ava.io.Serializable{=0A=0A           private Integer  length;=0A=0A        =
   private static Integer staticLength;=0A=0A=0A          //getters and set=
ters for both fields=0A} =0A=0A=0Aand I use JSONObject.fromBean( new MyBean=
() ).toString() to=0Aget its JSON string representation, in which case I ge=
t=0A=0A=0A{"length":0}=0A=0AWhy is staticLength not included in the JSON st=
ring?=0A=0A=0AThanks,=0AFlorian    =0A=0A=0APS:  I am in the process of exp=
loring the capabilities of =0A       json-lib, so I'll try to post some goo=
d questions in =0A=0A       this mailing list, and hopefully that will make=
 it =0A       easier for people to get familiar with the library.   =0A    =
