Re: is it possible to cache sql queries?

[Antonio Gallardo]

AFAIK, the SQL tranformer is not cacheable.

Re: extra-classpath issue ?

[Antonio Gallardo]

Hi gilles,

knowing how the tomcat classloader works might help you a lot [1].
Also, you should use only one application. Merge the cocoon directory 
and integrate the whole web application in the same directory. Please 
check the Bertrand presentation for best practices. [2]

Hi,

I'm using cocoon 2.1.8 deployed under tomcat 5.5.15
My jdk is 1.5.0_06, my OS is Red Hat Enterprise Linux ES release 4

I wrote a cocoon based application whose files are located in a directory
/var/www/webapps/visumtd/ apart from the cocoon webapp directory 
which is located in /var/www/webapps/cocoon/. I mounted this application

through the mount-table mecanism and it works fine.

This web application needs some specific jar files to run and I want these jar
files to be located in the application file hierarchy, not in the cocoon
webapp one.

I used the extra-classpath parameter in web.xml of cocoon webapp to specify
the path to those jars :


 

/var/www/webapps/visumtd/WEB-INF/lib/visuMtd-v0.0.3_j2dk_1.5.0.jar:/var/www/webapps/visumtd/WEB-INF/lib/metadata-0.0.1.jar

   


but this had no effect and the classes of those jars are not known 
(ClassNotFoundException)


I tried to use the ParanoidCocoonServlet instead of the CocoonServlet as 
suggested in the web.xml comments but with no effects. I also tried to set

the value of the "init-classloader" parameter to true. Still with no effects.

Of course, when I put the jar files in the WEB-INF/lib/ directory of cocoon 
webapp, everything works fine...


I've browsed the cocoon-users list archives : it seems that some people meet 
the same problem, but I didn't found any answer.


Does anyone have an idea ?


Thanks,

Gilles

Re: Access bound bean itself on CForms - also hibernate reattach object to hibernate session on view.

[Simone Gianni]

Hi Andre,
you cannot actually access the bean from the template, since the 
template does not even know that there is a binding and a bean. Anyway, 
you can pass the bean (and the session, and everything else you need) 
from the flow to the (JX) template passing it as a bizdata, for example :


in flow :

form.showForm('myform.def.xml', {"bean": mybaean});

in jx template you can then access the bean with ${bean.method()}.

The flow/view/hibernate problem is commonly not easy to solve, there has 
been a recent thread about this : 
http://marc.theaimsgroup.com/?l=xml-cocoon-users&m=114164895800296&w=2 . 
In the second mail of this thread i posted a possible solution we are 
using in our cocoon+hibernate+spring projects.


Hope this helps,
Simone

You don't need an  element to implement anchors, any element
with an id attribute will do, and is in fact the preferred method since
HTML4.  All HTML fields produced by CForms already have an id attribute,
so you should be able to use that.

Perhaps you can add an onclick handler to your button that adds the id of
that button to the end of the form action as a fragment identifier before
submitting:

  onclick="this.form.action += '#' + this.id;"

Unfortunately the styling XSLT already adds an onclick to buttons, so you
may have to override the appropriate template(s) to add your custom
onclick.

Or another approach might be to override the built-in submitForm JS
function, by adding something like the following to your own JS that gets
loaded after the base cforms.js:

  cocoon.forms._orig_submitForm = cocoon.forms.submitForm;
  cocoon.forms.submitForm = function(element, name) {
var form = this.getForm(element);
form.action += '#' + element.id;
this._orig_submitForm(element, name);
  }

(Based on cforms.js in 2.1.8, assumes the JS API doesn't change.)  This
would add the fragment identifier for all form submits, which may be what
you want or maybe not.

Hope that helps

No ajax, but page with long repeater...

[David Park]

Using cocoon 2.1.8, here is the problem:

Say a form has a repeater with many rows. If there is a repeater-action 
at the bottom that adds a new row, clicking it causes a form submit, and 
the user ends up at the top of the page, where the new row sits at the 
bottom of the page.


Likewise, if the repeater rows themselves have nested repeaters, any 
action that causes a form submission leaves the user at the top of the 
page, in a different "context", if you will, than where they performed 
the "submit action".


Is it possible, without ajax, to have a page submission target the 
widget that was "acted upon"?


Is CForms able to output an  that is 
targeted somehow via an http://my_continuation_url#repeater-row-id?


Many thanks to anyone who has any assistance to offer.

Hi there,

I've been trying to set the first form item to have focus when the form is

document.form.name.focus();

but the issue seems to be that CForms uses a name:input format for the id.
Is there a way of setting the focus in CForms? I looked at the Widget API
but couldn't see a function to set the widget as focus (unless I'm missing
something... which is quite possible).

Thanks,

Cached objects and http header 'range'!

[Marcel Rouwenhorst]

Hi,

 

I see that some readers i.e. the ResourceReader and DatabaseReader
accept http header ‘Range’. These readers also supports caching. 

 

But what happens if a object that is already serviced
by a reader and is cached by the pipeline cache, is requested by a client that
asks for a specific ‘Range’?

Is the cache capable
of streaming this ‘Rang’ or does it stream the complete component?

 

 

Thank you,

Marcel

Could you use a transform (XSLT?) directly after the calendar generator
to add your specialized content?  Just a thought.

Then that's impossible. It will stop at the first part that throws an

As I wrote, the exceptions are not caught, so it is impossible that
map:parts that follow the one which gives an error are executed.

It really doesn't matter, as there's nothing to fix there. While I do
think that sending additional SAX-events after an exception occured is
wrong, changing this will not cause a reliable alternative behaviour, as
the resulting behaviour would just be a coincidence of implementation
details of other transformers. Don't forget the SAX-pipeline is
streaming, you can't pull back events which are already forwarded to the
next transformer.

This being said, ContentAggregator.generate() is where it happens.

While Cocoon does create a request object wrapper for each internal
request ("cocoon:" request), most things, including setting request
attributes, are delegated to the original request object (at least, I'd
be very suprised if it's different).

Careful here: if you set a request attribute in say, a generator of a
pipeline called from a map:part, and read it out in (e.g.) an action in
the original pipeline, then that won't work indeed.

This has to do with how the sitemap works, the following resource might
help you understand this:

RE: jx templates and syntax

[Danny Bols]

If you write the following, myVar wil be a collection of dom nodes:

test
${myVar.getClass().getName()} -> [Lorg.w3c.dom.Node

To get the text value you should write:

${myVar[0].nodeValue} -> test

Calendar generator -> adding Content

[Joost Kuif]

Hi,

Does anyone have a working example of how to add content (like a simple
anchor tag) to the Calendargenerator with use of a overridden subclass?

I haven't seen one in the example block, but maybe I am missing
something.

Thanks,
Joost
