Hi Deepal,
I don't really consider POJO support as appropriate for web services of
any complexity, since it directly exports the object model as part of
the service definition. It also is generally unable to cope with data
structures of any complexity, such as hash maps and even collections
(other than typed arrays), or any form of object graphs. These are the
same issues which led to the deprecation of rpc/enc - though rpc/enc at
least had support for object graphs.
Based on my experience with client organizations, I've seen very few
real-world applications which could successfully be exposed directly
using POJO service support. And based on the POJO guide for Axis2 I
wouldn't call the use of POJO very easy on the client side.
Do you disagree on these points?

Hi Dennis ,
I quickly went through your article and in the conclusion you have the
following which I do not agree
*JiBX* is the only alternative that supports working with existing Java
classes, though Axis2 does include a limited form of plain old Java
object (POJO) support that can be used for simple cases. It also
provides the best support for unwrapped service methods in Axis2. But
the JiBX support integrated into Axis2 doesn't handle code generation
from schema, and even the separate code generation from schema support
provided by the JiBX tools provides only limited schema support.
In Axis2 we support any kind of Java bean , there is no limitation
for simple classes . Only thing we do not support in our POJO is
enumerations, and we have a bit test cases to validate whether we are
doing it right or wrong.
Yes at the initial stage we had only support for simple class but not
anymore .
Thanks
Deepal
My devWorks article comparing ADB, XMLBeans, and JiBX data binding
with Axis2 has now been published:
http://www.ibm.com/developerworks/webservices/library/ws-java3 I *am*
the primary developer for JiBX, but tried to give a fair
representation of all three frameworks in the article. It also
includes full sample code, for both the current 1.2 release and the
in-progress 1.3 release.
While I'm promoting my own stuff, I'll also mention that I'm planning
a trip to Australia in early September for on-site consulting and
training visits (see the Axis2 training course outline:
http://www.sosnoski.com/companys/axis2class.html), and will follow-up
with another trip to the U.S. later in the (northern hemisphere) fall.
Visits to other parts of the world can also be arranged... email me
directly if interested.
