[ANN] FP TagLib
Dear All,
A preview release of the FP TagLib is available.
It's a kind of "pre-cocoon-donation" version, I'm interested to see if it
runs on other's setups and if people think they'll find it useful.
You can download it from here:
http://www.media.demon.co.uk/fp/fp.sit.bin (MacOS)
http://www.media.demon.co.uk/fp/fp.zip (WIN)
http://www.media.demon.co.uk/fp/fp.tar.Z (UNIX)
Apart from the install files, there are basic dox, a sample site and the
source code.
There's a few issues to sort out before this could be included in Cocoon,
namespace, tag names, package names, code quality, etc.
It is difficult to tell at this stage which of these will change.
Enjoy
regards Jeremy

Brilliant, thanks for doing this.

That's really cool! I haven checked on the fp taglib and think
I should ;-)

No, I am not using RevalidatingDOMParser yet.
Can you please try this ....
Edit the XML file "item-add.xml" changing the output StyleSheet to use
"form-xml.xsl" instead of "form-html.xsl".
Send me the output

Do Unix people generally have access to un-zip code?
I will re-make the distribution.
It would be really handy if anyone who has managed to get the sample that
came with FP TagLib to work correctly, to let me know (off-list).

FP beta-testing feedback (was: Re: [ANN] FP TagLib)
Posted by Jeff Turner <je...@socialchange.net.au>.
I spent much of today playing with FP, and couldn't quite get it
going. Has anyone else got feedback?
I followed the installation instructions exactly, I hope (Tomcat
3.2dev, Cocoon1.7.5dev from CVS).
Clicking on the first "[add]" button (item-add.xml?item=1), I get a
form with no labels anywhere, empty drop-down lists and a label-less
submit button. It seems that the <fp:read> tags aren't doing anything.
To illustrate, the line:
<fp:read as="node" from="external-item" select="../item/title"/>
is supposed to generate:
<title>Title 1</title>
<title>Title 2</title>
<title>Title ...</title>
and doesn't.
A possible cause: the FP class fpResource uses
org.apache.xerces.parsers.RevalidatingDOMParser, which isn't present
in the default xerces.jar for cocoon1 (1.0.3), cocoon2 (1.1.2), and is
currently broken (and commented out in build.xml) in the latest xerces
from CVS. I would have expected ClassNotFoundErrors, but didn't see
any.
Can't wait to get this going; it looks extremely cool :)

Unless I'm doing something dumb, I think this last file is corrupted.
$ gunzip -t fp.tar.Z
gunzip: fp.tar.Z: corrupt input.
Installing from the zip, form/default.xml is horribly mangled (even
for win;), ie it starts:

Please see how all this fits with my forms proposal.
I'm working on it now and I would be happy to contribute.
Well, just in case, I'm just an hour away from you (Crema). :-)

Re: Note on using SLECT COUNT(*) with the XSP SQL tag lib
Posted by Geoff Drake <ge...@mandes.com>.
You will need to check that your SQL Engine supports column aliases, if
it does try
SELECT COUNT(*) AS NUMROWS FROM xxxxx
This will give you a column called NUMROWS
i.e. <NUMROWS>11</NUMROWS>
The AS xxxx might be different on your engine.

Shouldn't "SELECT COUNT(*) count FROM table" work?

I have been using XSP tag lib for a while and within the same page another
query works fine. So I knew everything was setup properly. I mean, for a
SELECT COUNT query, you are assured to get at least one row back (well only
one to be precise).
Anyway, after a bit of thinking, I realised that I might have to specify a
column name as such:
SELECT COUNT(*) AS TheCount FROM Whatever
And it worked!!!!
I thought I would share this discovering with other XSP SQL tag lib users.

This is a nice idea, but we are going to end up with huge lists of
namespaces at this rate :)
We also ought to implement HEAD, PUT and DELETE, for completeness.

Lets assemble a list of the different verbs we are developing, so that we
can see what cross-over we have and then collaborate on a simple and
rational namespace (or small set of namespaces) for handling this stuff.

This would be very useful.
The FP TagLib (new name please :) creates a Hashtable to store errors in,
so that at the end of page rendering a decision can be made about whether
to save changes and/or redirect to <fp:redirect/>.
Error reports are dumped to the output as XML
<fp:error id="fp-1">
<fp:error-node/>
<fp:error-message/>
<fp:error-node-type/>
<fp:error/>
It also places an fp-error="fp-1" attribute into the parent of the FP Tag
that errored out.
If we could work out a shared error mechanism for TagLibs to use
internally, I think we would all benefit, specially in situations where you
want to mix Tags from different Libs.

I'm game but, time being what it is (?), and my not having any, would have
to defer by a week. I'm currently working on tag-lib stuff that should,
within the week be useful contribs, anyhow . . .
Can we make a community calendar to find an agreeable time for all?

Ulrich, don't under-rate yourself. We are all on a par in this. The
strength of a fleshmeat is that we can actually sit around and thrash
these things out immediately. we can bring laptops and code stuff on
the spot.

I'm all for it. I don't know if I can come, but I'm not a terribly

I would love to get together in the flesh with a small bunch of
people to thrash out some common issues dealing with session
management, form processing, CRUD tool generation and generic
connection to db/JavaSpaces. we have dealt with many of these
issues, as have many of you.
So how about those who can come to an informal workshop in paris.
Dave Parry and I (and anyone london based) can jump on the eurostar
and be in paris within 4 hours. The germans and Italians have it even
easier as far as I understand. I understand that Jeremy is diving in
scotland until Tuesday. I am up for an sort of jaunt to the continent
to thrash these issues out actually as the best chance we all have of
speeding up our own individual projects is for us to get some
commonality in our approach to these basic components.
Dave parry and I can come over any evening next week and spend a day
(thursday perhaps) on this. I'd say the weekend but i'd like this
acted on sooner rather than later and I have a friend's wedding to go
to next weekend.

Ok, so we're all beating around the bush in different ways :)
My authentication and session handling taglib will initially just
authenticate against a database, as explained in my previous mails. I
would love to incorporate authenticating against an (encrypted) file, if
that is what you are working on. Or someone else incorporates my stuff,
I really don't care about credits, I just want to get it done :-)
Here is my suggestion how I think we could seperate tasks:
- generic input handling, at first HTTP POST/GET, later perhaps LDAP or
something
- generic authentication and session handling, at first authentication
against a database and perhaps against encrypted files
- encryption(?)
- reading and writing arbitrary XML/XPath (Jeremy's fp taglib)
These issues are closely intertwined, for example:
- for fp I need authentication, I don't want every random user writing
to my XML files
- for generic authentication and session handling I need pluggable
authentication schemes and thus encryption
- for fp and authentication I need HTTP POST/GET support
So, should we all implement something and then see how we can merge? :)

are you driving at a generic input handling lib? I'm working on one now. I
need to look at jeremy's stuff though, to ensure I don't start duplicating
his stuff . . .
I do something like:
Read post / get, hash
Read xml 'form template', hash
compare validation params based on minimal rules (attribute name, 'compare',
value, 'value to compare input against')
redirect out xml form, populated with message attributes (rendered by xsl
beside the input) . . .
I know this is not grokable, so, I'll just see if I can contribute to
jeremy's work . . .

Well, not quite. We have:
1. swing input type -> xml schema type objects and a factory to assemble
them
2. an applet which uses 1 to assemble an interface by reading a schema file
and an instance of that schema (xml document)
It works very well, however.... it depends on 4 of our servlets which in
turn depend on what is tantamount to my application server (actuall, my
design, most of it was written by a better programmer (lafredet, you
lurking?).
I've been trying to remove the dependancies so you can all have a boo, but,
sigh, it's problematic. We've implemented authentication and remote file
services (the applet gets it's schema's and xml through a mediated step,
from a servlet). This is all for security reasons, since the applet is used
by numerous departments of several companies in several countries on one (or
more) servers.
I haven't given up, yet, but, it's difficult to untangle the gordian knot .

Thanks.
Before choosing a name, I want to think about the functionality.
Some of the Tags are purely to do with XPath access to files, while the
others are to do with logic around HTTP Method.
What I am thinking is to split this TagLib in two.
The HTTP Logic Tags could go into the UTIL:TagLib
(maybe there are other logic tests that would be useful too)
<util:if-post>
post logic
</util:if-post>
<util:if-get>
get logic
</util:if-get>
While the XPath-File Access Tags could go into their own TagLib, giving it
a clearer, simpler purpose.
What does not fit into this scheme is the <fp:redirect/> tag, it does not
fit neatly into UTIL or an XPath TagLib, but needs access to Errors
generated by the XPath functionality as a redirect should only happen after
a POST with no errors.
Hmmm.

Get XSchema Validation working

A lot of the error messages come straight from Xerces
Can you plug in multiple language error messages to Xerces?
