Not to
shoot holes in your VB developers idea but if you do this, you would have to
maintain a separate XML messaging layer. This messaging layer would need
to define all your parameters and will add considerable time to your
project. Not to mention the overhead of instantiating an XML object.
You also would not be able to generate appropriate Java Docs. Your
one parameter for every method would be a XML string or a XML DOM
object. In my opinion, I would not suggest this approach. I'm
telling you this based on my experience, I worked on a project that passed
around a lot of XML.
Good
Luck,

XML
Got a question about Java and XML:
Let's say you are interacting
with some sort of Session bean and the method you are going to access is going
to return a collection. It seems to me that you could do this just as easily
by returning an XML string to the client. The problem that I am having is that
I can't find anyone who supports this idea, via examples or in technical
articles, so it makes me wonder if I am wrong but I just don't know it yet
:P
As well, I spoke to a VB
developer friend of mine and they use XML to pass a method parameters. He said
this was extremely useful because if he wants to add a parameter to a public
method that he does not have to break his binary compatibility. Once again,
this sounds great for Java but I have not been able to find any examples in
how-to's or technical articles.
I'm interested in hearing
some feedback on the up's and down's of using XML to send parameters and
return collections or lists. As well as, where I might find some examples of
how someone else has implemented it.
Thank you,
