Comment on JAXB Castor Comparison by Amin

Another case is : when u have a huge code base already in production and all model classes are already existing , same object may be going to JMS , Database or some analytic’s. etc

now for XML
we would not use generated classes – means manually writing annotations to hundred of model classes . which are also used by other layers they have to do testing as well .

“For Castor you need to manage the XML file containing the bindings, to configure the application to read it from some where, … etc. On the other side fot JAXB you have everything in the generated class. JAXB seems better here.”

I have used castor on many projects and from what i see is this is Actually an issue with JAXB not any feature..

reason is : 1 we are forced to have annotated classes and it relies on generated classes , from maintenance perspective , its much better to have a binding /mapping file since it is one place where u have all your mappings , vs its spread through out your model classes and n number of classes have to be changed – which also means more testing expense .

In case of Complex object structures with inheritance — to understand how object is mapped to xml i would have to open objects and read annottaions and assuume the xml and which is very impractical

if xml structure changes we can manage it in most cases just by modifying mapping xml .

It also seems to be dependent on schema which is a good feature but shud be an option not mandatory

Hi,
thanks for your post.

I have additional reason for Castor: When you use a lot of similar web services in your application you can map different XSD files (with the same definition) to one object.

I tried castor with objects and was able to get xmls although mapping didnot work perfectly.
jaxb w’d be pain.
Jaxb-2 is using annotations and is dynamic like castor(probaly using reflection like castor now)

but castor had all that long time back.

castor commiters, pls. add annotations support to kep jaxB folks quiet.

O, but I still don’t get it. I’ve followed this example, implemented and executed it. OK, it’s fine that we can put things differently, but don’t really get the advantage. Actually, it’s kind of weird for debugging, isn’t it?

And it’s code-invasive. So I’m trying to find an example where I could really see the difference. I guess when we’re using an interface, it’s because in few cases we’ll use an implementation and in another case we’ll use another one, but how shold this be working? I mean, what advanatage I have?

Apart from that, I have to say you put the easiest post to follow this. Congratulations and thank you.
