The simplest integration is probably to initialize the Spring 
application context in web.xml with a ContextLoaderListener:

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

Then you can get access to the application context from anywhere you 
have a cocoon Context object, e.g. from flowscript:

var appCtxt = cocoon.context.getAttribute(
Packages.org.springframework.web.context.WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE
);
var myService = appCtxt.getBean("myServiceBean");

There are also other techniques for getting access to Spring managed 
services; do a search for "spring" at http://wiki.apache.org/cocoon for 
some examples.

The next major version of Cocoon (2.2 or 3.0, not sure what it will end 
up being labeled) has actually been changed so that it uses Spring 
internally for its component management, so the integration should be 
that much cleaner.

In terms of Spring MVC, I don't know how it and Cocoon would play 
alongside each other, since Cocoon is itself an MVC framework. 
Personally I've never seen a need to use Spring MVC when I've got such a 
good one in Cocoon. :)  I'd be interested to hear if anyone else has had 
experience combining them though.

Re: Cocoon form/ajax problem

Hi Duncan,
I think you should use the <fd:widgets> element :

<fd:group>
  <fd:widgets>
    <fd:submit .....

If not, the definition builder simply ignores your submit button.

Hope this helps!

Re: CForms tree-model using xml as source?

Hi Fred,
this seems to be nice stuff, if you can, why don't you contribute it?
You can do that opening a JIRA issue with "[PATCH]" in the title, a
description of what your code does and how it works, and then attaching
your source code to it.

custom validator is not called

Hello, 

I'm using the following construct to display or hide a field. This is only an Example, I'currently testing something.
My problem is now, that my Java validator is never called. Is this a Bug or did I make a misstake? When i use the
validator elsewhere, there's no problem.

Thanks Mike

Re: Cocoon and Spring

Re: Cocoon and Spring

What Hibernate fiasco?? I thought Cocoon & Hibernate worked pretty 
well together?

>>> werdafucami <at> gmail.com 2006/06/01 11:10 AM >>>

Great thanks heaps for that Jason. Thats pretty much what I thought was the case with the MVCs. I am an XML
processing fanatic, so I am heading Cocoon all the way It is interesting to see that Cocoon and Spring
are getting closer links. Lets hope it doesnt turn out like the whole hibernate fiasco!

Cforms repeater

Hi,

I encounter a problem with a cform.

I have a repeater that creating trouble with the rest of the form :
When I  "add a row" or "delete a row", I lost the focus on my "htmlarea" 
widget and "multivaluefield" widget. Why That ?

I also saw that we need to do a workaround in the submit widget to 
handle correctly the htmlarea values. Is it the case in cocoon 2.1.7 ?

Thanks

Lionel

Right, it looks like a custom
FormattingDateConvertorBuilder/FormattingDateConvertor would be
needed. The standard builder just calls:

convertor.setNonLocalizedPattern(pattern)

If there's no locale provided for a pattern. So, you'd need a
builder/convertor that would do something like this instead:

convertor.addNonLocalizedPattern(pattern) // new convertor method

The convertor would then have to cycle through the non-localized
patterns and use the first one that formats/parses without an error.

Flowscript file permissions on mkdir - pls help!

Hi,

The following flowscript dynamically makes a directory and uploads a 
photo to it:

===Extracts===

  var uploadWidget = form.lookupWidget("upload");
  if (uploadWidget.getValue() != null) {

      // test if user directory exists, if not, create it
       if (!userDir.exists()) {        
           userDir.mkdirs();
       }
    uploadWidget.getValue().copyToFile(userDir + "/" + fileName);
  }

===========

On Windows this works great; but on LINUX, the folder gets created with 
0755 permissions (set by my ISP). This is insufficient to run my PHP 
script on the photo -- which needs the folder to be set to 0774.

How do I set the folder permission values from this flowscript?

Thanks for helping this total newbee!

Daniel
