Axis 1.2 - Object graph serialization

[Vali Grigoras <gr...@gmail.com>]

Hello,

I'm a newbie to Webservices and I have a simple question for you regarding
RPC web services and java objects serialization. I would like to know if
there are any limitations in serializing objects graphs. For example if I
have a one to many relation between a Parent and Child and the data model
looks like:

  class  Parent {
    private String name;
    private Set children;
    ...
    // removed the getter and setter
  }

 class Child{
    private String name;
    private Parent;
    ...
   // removed the getter and setter
 }

Any help is greatly appreciated.
Vali

Hi Vali,

Axis 1.2 does not support serialization of Set attributes. You will have 
to convert them to arrays.

While you stick to RPC/encoded style you will have no problem. 
Document/literal does not allow references, and so it forgives loops in 
your graph. This means that your "parent" field in the Child class 
should be removed, because otherwise the serializer would enter into an 
infinite loop and crash your server with an OutOfMemory.
