xsp castor taglib for editing databases via HTML forms
some of you had asked about this, so I packaged up my latest version and
have put it up on the web here:
http://www.webslingerZ.com/balld/wz-castor-0.2.zip
you will, of course, need cocoon, castor (http://castor.exolab.org/), and
a database that castor plays well with (postgresql, for instance - mysql
is out for the moment due to lack of transactions).

I can't vouch for Turbine, but I think there should also be a "standard"
or "preferred" way to do user and session management in cocoon. In my
mind the easiest thing would be to use a database - that way we could
use its advanced security and transaction features. Communication with
the database should be encrypted, so that passwords are not sent across
in the clear.
So, perhaps https with a database and the ServletEngine's session object
could solve these problems. Any comments?

Can Turbine do this part of the job ?
Cocoon is really great for publishing, and well enought for building
applications. But it lacks some commun buildin functions...
I don't know if all can be done with taglibs.

It's a bug in the Xerces 1.0.3 distribution that comes with Cocoon 1.7.4
There is a 1.0.4 version of Xerces that fixes this but there are some issues
with Xalan that supposedly can cause problems. I have been using 1.0.4 for
a while without noticing anything strange though.

Bug in Coccon when using
Posted by Andy Bosch <An...@csi.com>.
Hi,
I am using cocoon for some month now. So I am
not a newbie. But now I found a strange behaviour:
When I use imagemaps in xsl-files, cocoon drops my end-tag
( </map> ) during processing without any replacement. How could this
be?
My xsl-source is as follows:
<map NAME="mymap">
<AREA SHAPE="CIRCLE" COORDS="137,175,6" HREF="aaa.html""/>
</map>
<IMG SRC="/pic.gif" USEMAP="#mymap"/>
The problem again is, that after processing the xml with the xsl-file, the
</map>-Tag
is missing.
Thanks in advance,
Andy

if can be useful, i did a special xml-tag (like <myns:login/>) that checks the
get/post parameter and/or the httpsession obj. if the session in correct go
ahead, if not sendredirect to login-screen.xml page. you can pass the local
page, so to go back after a sucessful login.
it's a very simple approach, i hadn't serious security problem.
now i'd like to investigate on producer and processor. probably a producer can
do a good job of session control. to the guru of the ml: any suggestion?

You shouldn't have to write a 'proxy' servlet - you have full access to the
servlet session api in your xsp pages. You can either wrap native java in
<xsp:logic> tags or in cocoon1.x use the session taglib.

Hm... since Cocoon is Servlet, Session management should
not be too hard to go for. But I have just a very limit
view of what is possible with Cocoon. Maybe someone with
a little more insight (than me) could comment on this topic.
Worst case I could maybe write a Servlet that does the
Session managment and uses Cocoon just for the display.
But that would need this Servlet somehow function like

Multi-language and WAP is pretty straightforward in cocoon. Security and

Building a site involves much more than cocoon provides. It is not a
site-management tool, but something on which every site-management tool
should be based :)
I can only say cocoon has (like every software) a few shortcomings, but
it is in another league than anything else I've ever used. Most cocoon
users will say that it rocks. The important shortcomings will be dealt
with in cocoon2, the rest is mostly stuff that no-one has found time to

cocoon really an option
Posted by Torsten Curdt <tc...@dff.st>.
I'm now running Cocoon under Linux/JServ and
WinNT/JRun and I'm amazed on something that
is really working with this "new" technologies ;-)
I've now checked the examples and have to
make a decission if it's the right way for
our project. I'm not sure - so maybe someone
can give me some feedback.
We have to support multi-language, login
environment with shopping cart functions
and later on - WAP.
What really makes me nervous... I haven't
found any big projects using Cocoon up to
now. (At least there were just a few links
on the Cocoon website)
Is Cocoon scaleable enough?
And I haven't found much documentation on
building such sites with Cocoon. (Have I
been looking at the wrong place?) A getting
started tutorial would be great!! Or at
least some more comlex samples!
If Cocoon really confirms my good impression
I'm a volunteer on starting something like
that ;-)
Hope to get some feedback

um. where to begin... sql taglib is just a stupid little wrapper that
executes sql queries and formats the results as XML. there is nothing
complex or even really interesting about the sql taglib.
castor is a nice library that lets you treat java objects, database rows,
and xml fragments sort of interchangeably. castor eases the task of
editing databases by hiding much of the stupid SQL stuff from you - you
don't have to construct an insert statement when you want to edit an
entity - just create a new object, set a few fields if you want, and then
ask castor to add it to the database.

you need to add the bsf.jar to your CLASSPATH. sorry, i probably ought to

nice datetime widgets and xalan extension's rely on bsf. bsf is available
here:
http://www.alphaworks.ibm.com/tech/bsf

uh... the primary portion of the taglib _is_ cocoon-based, obviously. i
use a standalone servlet to do the final database commit because cocoon's
overhead is not necessary or even desirable for something that simply
executes a database command and sends a redirect. i reckon you could
rewrite it as a taglib or something, but _i_ can't see any good reason to
do so.
