What's the best way to handle arrays in javabeans especially for
XMLencoding and decoding?

Is there anything different from plain old Java? See

You have been particularly sloppy in posting your URLs lately, Roedy...

And btw...

I disagree wholeheartedly with you concerning xml.
I think its the best thing since sliced bread within
its domain. Used without thinking, any dataformat can
be misused.

Using it to store your record-collection database, etc
is sheer idiocy, but to send the information on a particular
record to another app, its perfect.
(The Records.xds is of cource published publicly, so
anyone who wants to build a record-collection app.
can use it to validate the data-exchange).

And *do* revisit Xml Schema and read it thoroughly.
http://www.w3.org/TR/xmlschema-2/

And forget about the (old) DTD, XSD have taken over.
Xsd can define datatypes, ranges, enumerator, dates,
complex datatypes, et.c.

good. Now if they can get rid of the fat. I hope fluffy XML is just a
stage in the evolution and eventually what we now call XML will become
a debug dump format, and the real format will be something nobody ever
looks at. You just interact with through APIs.

Then after that is the lack of generality. Not everything in the
dataprocessing universe is a tree.

But must give it credit for some strange appeal that is making
intoperatibility a reality.

I have added a section on Schemas. You might want to check if I got it
right.

I did a quick scan over the docs. It was not clear if you can create
an enum of the US states or if that is now considered a primitive,
which is what I have been pushing for since 1979.

Thanks guys! But I was wondering how I can use sun java's wonderfule
xmlencode and xmldecode with a slightly more complicated data
structures.

BTW, I think what should replace XML is just plain English! I cringe
to see how much effort is expanded on XML instead of learning to just
parse English better. Like the French, we should stand up against
alien languages :-)

I don't recognise those methods, but you might use
the XMLEncoder and XMLDecoder classes also.

Make it an attribute of a class, with a public getter/setter.
..Was there some trick to that question?

I am quite ill and my eyesight has not been working well. I can see
snatches of things but not the whole. Partner says I have all the
symptoms of the "dog flu". I am not sure if this is a joke. I go in
tomorrow to get checked out.

Hopefully this senility will be temporary.
