What is ecs2 ?
Hi all.
There is a repository 'jakarta-ecs2'.
What is the jakarta-ecs2 ?
What is different between ecs-1.x. and ecs2 ?
Is there a reference or any document ?

look in my home directory on apache.org for ecs.tar.gz.
apologies for taking so long to post it up.
this contains a directory structure which generates java source code from
xml-schema using texen.
(xml-schema is a kind of validation for xml which is equivalent to a DTD but which
is written in xml.)
there are three sample xml schema in the directory.
org.apache.xerces.domx.XGrammarWriter is a java application which will produce a
xml schema for an xml document which has a DTD. it's much easier to parse an
xml-schema than a dtd since a schema is just xml.
generate.xml is an ant build file that contains generation, compilation and
documentation tasks.
i can't test a .bat so you'll have to make do with a generate.sh to run ant
against generate.xml
the default task generates and compiles a family of ecs elements from a schema.
the generate.xml has a "name' property which you need to change to generate from
the different example schema.
look inside the template directory to find the template files. they're pretty easy
to read (thanks to velocity). the basic object model extracted from the schema
just gets attributes and subelements for each element. there's a lot more
information in there which could be used as well - for example type information.
the templates are more examples of how ecs could be generate rather than a serious
attempt to get close. the appendXXX methods are really a bit of a gimmick to prove
to myself that i can find subelements.
oh yes - the jars in the lib directory are specific versions which i know work. if
you've got different velocity or xerces versions in you classpath then you might
have problems.

i'm a bit worried that it might be a bit large to send since i need to include
some particular versions of some jars
i could either mail you a large attachment or i could (thanks jon) upload it
into a public directory in my account at apache.org
- the choice is yours -
BTW has anyone had a chance to take a look at that international characters
patch i floated a while back?

Just send it to my email address directly, lets not bother the list with

Stick it in CVS or put it in your account on apache.org.
Ie:
mkdir ~rdonkin/public_html
Don't post it to the list.

sounds cool!
by a strange coincidence i've nearly tidied up that generation stuff
i could either wrap it up into a gz and post it in an email (could be a
little big since it contains jars)
or i can upload it somewhere in CVS.
what do you think?

jakarta-ecs2 is a complete rewrite of ecs, no attempt was made for
backward compatability it improves memory footprint, speed, and it
changes the semantics of the Element classes so that you can now extend
them. It uses an Attribute class that you can pass around to other
elements so that you don't have to do the same setup work on the
elements. It uses an event model for output, and generally fixes alot
of deficiencies that I had with ecs.
> What is different between ecs-1.x. and ecs2 ?
Aside from the above, ecs-1.x ismore or less 'complete' while ecs2 still
has alot of work remaining, also work is being done to make ecs2 fit the
javabean patterns so that you can assemble an ecs document inside the
ide of your choice.
> Is there a reference or any document ?
Nope, I need to throw something together and put it in the repository.
