Re: Caching results of SQL Queries?

[Justin Fagnani-Bell]

Jeremy,

  If you're doing the SQL queries in a custom component (generator, 
transformer) you can use Cocoon's caching system. Have you class 
implement Cachable, and in the generateValidity() method you can return 
an object with the last modification date of the database.

see :
http://xml.apache.org/cocoon/userdocs/concepts/caching.html

and the API docs for Cachable and CacheValidity.

Dear All,

I have a set of related Tables in MySQL, which are used to build part 
of a site I am working on.

We use SQL because of the related nature of the data, rather than any 
great need for dynamics.

My SQL queries are broken down into 'components' which are CIncluded 
into my documents from internal pipelines. Usually there are several 
components that use SQL queries in each document. (It is done this way 
to isolate the implementation of components from their useage as well 
as from the main sitemap).

The data seldom changes . is there any way I can force the 
internal pipelines to cache, without using the tricks like browser 
caching via the 'expires' header on the external pipeline?

Thanks for any suggestions.

Yes, but a problem then arises when someone is using IE and they want 
a PDF, when your user-agent rules will only serve a PDF for FooCo PDF 
Browser 1.0.  IMO browsers should respect the mime-type header.  I 
believe the mime-type headers is very useful when you want to use 
something like a PHP script to send an image or a .tar.gz file.  In 
fact, it's essential for it to work, otherwise the browser interprets 
the data as garbage.

No, that's wasn't my intention at all.  If someone is using IE and 
they want a pdf (not a default expectation for that particular browser 
like html or xml), then the URL they would get directed to would be 
*.pdf. This is not the intrinsic resource.  You are explicitly asking 
for the PDF representation of that resource.

If the browser's default expectation is PDF (like in your FooCo PDF 
Browser 1.0 example), the trailing slash resource would give it PDF. 
However, it could still be pointed to *.pdf if you wanted to make it 
explicit.

This is very well put Miles, and was my intention with the previous 
email I wrote. Content negotiation and file extensions can (and IMO 
should) exist side-by-side. There is no precedent for a browser 
changing its accept header on a per-request basis, as someone 
suggested, not is there a way to specify this behavior in a hyper-link. 
If you have a link on a site that says "Click here for a PDF" then I 
would expect that the URI would end in .pdf, at least that's what makes 
the most sense to me.


In those cases where only PDF is available (common when it's not 
dynamically generated), I see no reason why the URI wouldn't be *.pdf.

Exactly.


This is where we differ slightly.  In my mind /a/b/ is the intrinsic 
resource.  /a/b/index.html is the explicit call for HTML 
represention of /a/b/.  If you redirect a client to /a/b/index.html 
and the client bookmarks it, they are bookmarking the HTML 
representation, not the intrinsic resource.

This is definitely where we differ. I don't see why an intrinsic 
resource should always end in a '/'. If /a/b.pdf is the PDF 
representation then why shouldn't /a/b be the intrinsic resource? The 
only reason I see why the trailing slash is recommended is because 
developers are used to having their URI space tied to their filesystem 
structure with a static server like Apache. The trailing slash, from 
our experience with filesystems,  indicates that something is a 
directory, that it has children. But in a URI a resource can be both a 
viewable resource and a container node at the same time. There's 
certainly nothing stopping /a/b/, /a/b, /a/b.pdf and /a/b/c.pdf from 
all being valid URI's in the same space. To me the trailing slash 
simple indicates that there's more to come at lower levels, and the 
absence of it means the resource is a leaf.

As for redirects, I don't see it being too much of a problem with more 
recent protocols. Also it should only happen when a visitor is being 
referred from an external page, since all the URL's in your site should 
be in the correct form. If you are linking to the intrinsic resource, I 
don't see the need for a redirect (as long as the browser correctly 
understands the mime-type header), so I don't see a problem with 
bookmarking.

P.S.  Thank god for the mailing lists.  They actually encourages me to 
write down some of my thoughts.  Even they are off the mark more often 
than not...  Does this make email better than web or simply justify 
the need for more discussion on the web?

Here here. I say both, linear discussion is good, so is collaboration. 
A discussion board combined with a wiki would be awesome. Discuss a 
topic and collaborate on a document summing up the ideas at the same 
time. Hmm... Cocoon could do that :)

Is anyone using cocoon.xconf files in Mounts?

[Justin Fagnani-Bell]

I'm having problems with Cocoon Mounts and using cocoon.xconf files in 
the mount sub-directories. I've posted about this a few times but 
haven't gotten a response, so I'm wondering if anyone out there is 
using mounts and cocoon.xconf files.

My problem is that I can't access JDBC datasources defined in the 
sub-cocoon.xconf files. I believe this is because to get a datasource 
you need to use a ComponentSelector, and I think the ComponentSelector 
for datasources doesn't have access to the components defined in the 
cocoon.xconf files in the Mounts.

I can't really find much documentation on this except for at the cocoon 
wiki where it just say this should be possible, and defining datasource 
is one of the reasons for having sub-cocoon.xconf files.

I'd love to hear if anyone has attempted this, whether or not you've 
succeeded or failed, because at this point it feels like I might be the 
only attempting this, and surely that can't be. There must be someone 
out there who's tried, one of the developers of this functionality 
maybe?

Thanks again, in advance, for any responses,
  Justin

Re: URL Theory & Best Practices

[Justin Fagnani-Bell]

Tony,

  I've wrestled with similar problems for a while with my content 
management system, which uses a database for content and structure. I'm 
in the process of setting the system to use file extensions for the 
client to specify the file type and have Cocoon return that type. If 
they request /a.html, they get html, /a.pdf and they get pdf, and so 
on. This seems elegant, but it has problems when you consider the 
points covered in the slashforward article. Here's the compromise I've 
come up with so far, adapted to a filesystem like you're using. I'm 
still toying with these ideas, so i'd like to hear comments.

1) Instead of having directories with index.xml files, have a directory 
and an xml file with the same name at the same level.
so you have /a/b/ actually returning /a/b.xml. you could map a request 
for /a/b/index.html to /a/b.xml as well. This way you can add a leaf, 
and if you need to later add sub-nodes, and turn the leaf into a node, 
you just add a directory and some files underneath it.

2) Redirect all urls to *not* end in a slash. I see the point of the 
article you've linked to, and agree with it, but the file extension is 
the only form of file meta data that's pretty standard. Ending all urls 
in slashes only works, in my opinion, if all the files are the same 
type, if not it's really nice to have a way of identifying the type 
from the url, not just the mime-type response header. So considering 
that any request is going to point to a leaf (or an error page), then I 
would redirect /a/b/ to /a/b.html

This way the extension isn't revealing the underlying technology of the 
site, but the type of file the client is expecting, and this goes for 
directories too.

The matchers would look something like this: (i might have this wrong)


  



  
  


Add matchers, or use selectors, for more file types.

Apologies for the extra long post, but this has been bugging me for a 
while.

First, some background:

I'm attempting to put together a URL space using cocoon that will 
allow users to drop an XML file into a directory, say 
$TOMCAT_HOME/webapps/cocoon/documents/ and have it published.  This is 
easy enough:


   
   


So then I decide that for organization's sake, I want to allow people 
to create subdirectories under documents/ any number of levels deep, 
and still have cocoon publish them. This is also fairly simple:


   
   
   


However, later I realize that using file extensions is "bad".  Read 
http://www.alistapart.com/stories/slashforward/ for more info on this 
idea.
This creates problems with how I automatically generate content using 
Cocoon.  I want to allow people to create content arbitrarily deep in 
the documents/ directory, but I run into a bunch of questions.

Should trailing slashes always be used? I think so.
Therefore: Consider an HTTP request for "/a/b/c/".

   1. Is it a request for the discreet resource named "c" which is 
contained in "b"?
   2. Is it a request for the listing of all the contents of the "c" 
resource (which is in turn contained within "b")?
   3. Is this equivalent to a request for "/a/b/c"? 3b. Should 
a request for something w/o a trailing slash be redirected to the same 
URL, but with a trailing slash added?

Using the "best practice" of always having trailing slashes creates 
problems when mapping the virtual URL space to a physical directory 
structure.  Considering a request for "/a/b/c/", do I go into 
documents/a/b/c/ and generate from index.xml?  Or do I go to 
documents/a/b/ and generate from c.xml?  Having every "leaf" be a 
directory with an index.xml gets to be unmaintainable, IMO.

Likewise, do I generate from documents/a/b/d.xml or 
documents/a/b/d/index.xml for a request of "/a/b/d"?  Additionally, 
what should happen when there's a request for "/a/b/"?  Obviously, if 
the subdirectory "b" exists, it would not be correct to go to 
documents/a/ and look for b.xml.

Part of my reasoning behind all these questions lies in my quest for 
creating an uber-flexible "drop-in" directory structure where people 
can simply add their .xml files to the "documents" directory and have 
Cocoon automagically publish them, as I stated above.  The other 
reason for this is that I'm trying to devise a system which 
automatically creates navigation, as well. I've looked at the 
Bonebreaker example, and it's good, but has some limitations.  What if 
I don't want to use the naming scheme they have?

Oh well, thanks for listening to my ramblings, and hopefully I can get 
some light shed on this situation, as well as have a nifty autonavbar 
work eventually :)

Tony

Re: Anyone? (was Re: More sub-sitemap questions)

Hi,

  Sorry for reposting this yet again, and to both lists, but I haven't 
been able to find a solution to something that I think should work, (at 
least according to the cocoon wiki, which specifically mentions that 
one of the uses for mounts having their own cocoon.xxonf files is to 
define datasources).

The scenario is that I can access components defined in 
sub-cocoon.xconf files, but only if they don't require a 
ComponentSelector. If they require a ComponentSelector it can't find 
the component and I get errors.

Re: dynamically choosing an action at runtime

[Justin Fagnani-Bell]

Josema,

  You don't have to include the parts of your pipeline that are the 
same in the  elements. You can just include the  
element, since it appears that you're not returning any parameters from 
your action, and then you won't have to duplicate the part that doesn't 
vary.

  An even better way would be to have a proxy Action class that 
dynamically loads a particular helps class depending on a parameter 
passed to it. Cocoon already includes something like this with 
ServerPagesAction, and you write the action in XSP.

Re: Accessing uri-prefix from within sub-sitemaps?

[Justin Fagnani-Bell]

Thanks for the reply Joerg,

I looked into your suggestion, but I don't quite see how to do it. For  
a project in development the URI will be something like:

 http://dev.myhost.com/projects/proj1/

and for a deployed project the URI will just be

http://somehost.com/

but after that the URI could contain any path, so I feel like checking  
if the URI starts with "/projects/*/" would be a hack and could cause  
problems if by chance the site contained a top level projects folder.  
I'm already passing either "projects/proj1" or "" (an empty string) to  
the stylesheet. I would just like to find a way to pass it to the  
sub-sitemap, from the main sitemap.

Anyway, this problem isn't that big of a deal, just a cleanliness issue  
really. I'm creating the development system so that there's a "deploy"  
button which will upload the site to the server, (like GoLive or  
Dreamweaver). Right now there's three things I need to do to any  
project folder, add the WEB-INF director, fix the sitemap to take away  
the "base" parameter, and add a correct cocoon.xconf file. I'm just  
looking to simplify the process. If anyone can help me on the  
cocoon.xconf problems I'm having I'd very much appreciate it. (I think  
it could be a bug see

and here's the error from the log file:

DEBUG   (2002-10-31) 09:24.36:845   [cocoon  ](/projects/spectra/) 
Thread-5/SQLNodeStore: SQLNodeStore.parameterize():

could not find the component for hint: NodeDB

This all works fine if the components are defined in the main 
cocoon.xconf file. I know the sub-cocoon.xconf file is being read 
because I can load my SQLNodeStore component. I think what's happening 
is that there's a seperation between the two cocoon.xconf files, and 
when I load the ComponentSelector I'm getting a ComponentSelector for 
the main file, which doesn't have a datasource called NodeDB. Is this 
possible? If so, is this a bug, or do I need to do something different?

Any help is much appreciated.

Accessing uri-prefix from within sub-sitemaps?

[Justin Fagnani-Bell]

Hi,

  I'm using sub-sitemaps now to host several projects at once in my 
development environment. I access the projects through a URL that looks 
like this - "http://localhost/projects/proj1";, and in the sub-sitemaps 
I have a XSLTransformer prepend a sitemap variable called base to the 
beginning of all absolute urls, so that all my links work. I end up 
entering the uri-prefix by hand, the matcher looks something like this:




  



What I would like to do is have "base" automatically set by accessing 
the uri-prefix set in the mount element on the main sitemap, then when 
I deploy the project, there's absoutely no changes that need to be made 
to the sub-sitemap. Is there a way to do this?

Re: Running command-line programs in a pipeline

[Justin Fagnani-Bell]

Peter,

You could certainly write your own serializer to do this. I haven't 
written a serializer, but I'm pretty sure the input needs to be SAX 
events, so the only ways you could use XSLT to output LaTeX is if you 
did the transformation within the serializer, or wrapped the LaTeX in 
XML.

Another solution would be to have an intermediary step where you 
transform into an XML dialect that your LaTeX serializer understands. 
This is how FOP works, and xsl:fo is the intermediary step. I would 
definitely see if you could use xsl:fo for this purpose so you don't 
have to reinvent the wheel.

As for calling the command line program you can use Runtime.exec() and 
write and read from the Process object that it returns. There are 
inherent scalability problems with this approach though. I'm not 
familiar with LaTeX, are you sure there aren't and Java based LaTeX 
tools?

What DTD's do you use for a plain site?

[Justin Fagnani-Bell]

What Doctypes are people using for general information to be displayed

I'm doing a very simple site which will be mostly static HTML. The data 
is basically intended for presentation only, so there isn't much of a 
datatype I need to model, the only reason I'm going for cocoon is to 
swap out look and feel easily.

So far my experience with Cocoon has been with data I could come up 
with a logical XML dialect for. But for presentation orientated data I 
find myself just using html, which I know I shouldn't.

Any suggestions? I'm about to check out DocBook, but is that maybe

My first reason for not using a generator to handle the SOAP request is 
that it doesn't quite fit into the role of generators, I think the 
generator should be used to create the response.

But the real problem I see here is how to do something useful with the 
SOAP request. Once you receive the request you've go to do something 
with it. If all you have is a SOAPGenerator and a SOAPSerializer, then 
all you can so is put some transformers in between them to turn the 
request into a response. You wouldn't be able to do a whole lot unless 
you wrote your own transformer. With the built in transformers the most 
complex thing I could see doing in using an XSLTransformer and the an 
SQLTransformer to do a database lookup. If you want to perform some of 
the functions that are typically done with Actions or flowscript you'll 
need Actions.

If you had a SOAPAction though, you could take information about the 
soap request and place it into sitemap parameters, from there you could 
use those parameters with selectors to choose appropriate pieces of the 
pipeline.

It's kind of analogous to the difference between RequestGenerator and 
RequestParamAction. RequestGenerator is useful for using the request 
parameters and headers in the output, but RequestParamAction is what 
you normally use when you need to setup parts of your pipeline based on 
the request.

I'm not aware of too many important HTTP response headers besides 
content-length, redirect-to, and mime-type. I'm not that knowledgeable

Got me. I followed the discussion of the dev list for a while, but I've

Why not use an Action? Then you could set sitemap variables, call other

Would the current XMLSerializer work for this? I'm not that familiar 
with SOAP, but I was under the impression that it was xml documents 
sent via HTTP.

Sounds nice. You could keep the piece that transforms the sax stream 
into soap separate from the soap client. That way you could just use an 
xsl stylesheet, or any other transformer, to create the soap and it 
would be more controllable by the end user.

Another thought is to have a SOAPAction that does a similar thing, this 
way you could receive a request, access a soap server, then setup the 
pipeline based on the results of the soap request. And maybe there's 
even a way to integrate this with flowscript so that flowscript can 
perform actions based on incoming soap, or you could access a soap 
service from within flowscript.

If it was a soap action rather than generator it could set sitemap

You could chain the transformers, or use an aggregator for this.

Using Cocoon via the command line?

[Justin Fagnani-Bell]

I can't find any documentation on this, but how do you use Cocoon from 
the command line? I've buit a site that's going to be hosted on a plain 
old webserver and need to export the cocoon generated pages. I've been 
doing this with GoLive's download site feature, but I know there's a 
better way. I can find info about the CocoonCrawler in the API docs, but 
no user documentation on this.

Can someone point me to the right place, or explain how it's used? I'd 
be willing to add something to the Cocoon Wiki about this.

Thanks,

Re: Using views

[Justin Fagnani-Bell]

Igor,

   I think you can do what you want with a map:aggregrate, but not in 
every pipeline. Try somehting like this:


   
 
 
   
   
   


This will match every url and then aggregate it with your other 
matchers. Then just have all your other matchers start with "part/".

Of course, I've never used views, so I don't really know if it's easier 
or even possible with them.

I can't think of any way to do this with the included Cocoon components, 
but you could write an action that does this. Create a matcher that does 
the XML+XSL->PDF transformation, then in an action access the url for 
that matcher and saves to a file. I forget if action can access a 
pipeline with in an action with something like 
resolver.resolve("cocoon:/pdf"), if not you'll have to use the 
java.net.url classes.

You could also write an action that actually loads the file, performs 
the transformation, serializes to PDF and writes the file, all 
configurable by sitemap parameters, but the action that saves a url to a 
file seem more generally usable, it could be a good addition to Cocoon.

cocoon-users@xml.apache.org

[Justin Fagnani-Bell]

Hi again,

this is a long post 

   I'm still working on HTML forms where the user (me for the moment:) is 
supposed to input HTML into a text area that will be stored in an XML 
format. I'm still having problems, so I haven't written a SUMMARY post...

My new problem occurred last night when I'm testing the system and I put 
in an anchor tag with a url that has request parameters... like this:

http://www.something.net/apage.jsp?p1=hi&p2=bye";>link

Well, when I hit submit the form is supposed to come back filled out, 
but instead I get an error that states "the entity 'p2' must end with 
a ';'.

So I do some searching on on w3.org and sure enough URLs in XHTML have 
to use '&' instead of '&'. Arrgh, I know this will cause problems 
once people who are used to normal HTML start using this. I'm 
considering writing a filter that will escape illegal characters on the 
way in, and un-escape them going back to the user, but that seems like a 
bit of a pain and combined with the problems I'm having making people 
type XML compliant HTML in the first place I'm wondering if there's a 
completely different way I could do this.

I'm sure someone else out there has come across these problems before. 
It seems inevitable when building a webapp where users can edit some 
content, that uses XML on the backend. The users only marginally know 
HTML in the first place and can't be expected to always follow the rules 
correctly every time. The app after all, is supposed to be easy to use.

I would love to start some discussion on different ideas for handling 
these types of problems. They must be common among Cocoon users, and 
maybe we can come up with a set of solutions (HOW-TO's, Java helper 
classes, taglibs) to make life easier on Cocoon developers and end-users.

Here's my little list of requirements, issues, and assumptions when 
dealing with forms, user input, and xml.

1) My users are used to HTML, not XML
2) My users are not fail proof, and are probably prone to occasional 
mistakes
3) Ideally I want them to be able to input HTML(non XML compliant), 
plain text, or XML (not HTML, but any XML. this is actually preferred, 
but sometimes users are just entering a news item, or a BBS post, and it 
seems reasonable to allow them to use HTML for formatting rather than 
inventing my own xml dialect)
4) The data is going to be in an XML document/SAX stream at some point
   (either stored that way, or stored in a database and turned into xml 
through a generator)
5) sometimes I want to run xsl transformations on the data when it is 
output.
6) when editing the data, I'd like to have it appear exactly as the user 
typed
7) but i'd also like to have the ability to clean it up (as on option)
8) The browsers like HTML 4 much better than XHTML, therefore the pages 
I send them work better if I use the HTMLSerializer

Here are some problems I've encountered so far.

1) users don't follow XML rules very well (goes along with point 1)
2) the HTMLSerializer changes the users data by turning  into , 
etc
3) the XML Serializer changes the users data by turning 
 into , etc
4) bad user input will cause SAXExceptions if it's not enclosed in CDATA 
sections

(oh, to clarify here, I typically have two pages which show the data, 
one is the 'edit' page with the form, the other is where the data 
actually shows up, the 'viewing page', the HTMLserializer is no problem 
on the viewing page, just the editing page)

Some of these points interfere with some solutions. For example, I could 
wrap the data in a CDATA section to get around XML compliance, but then 
I wouldn't be able to run XSL transformations on it (correct me if I'm 
wrong anywhere). Maybe I could check if the data is xml compliant and 
wrap it only if it isn't.

Here are some ideas for solutions:

1) Create a new HTMLSerializer that can selectively determine which tags 
it will convert into HTML and which is will leave alone. This way you 
could specify that all textarea tags and their contents shouldn't be 
touched (I would think this would be a reasonable default feature anyway)
2) Create a jTidy like program that will turn HTML into XHTML, but work 
for fragments (jTidy seems to only output complete HTML documents)
3) Create a class that can find an XML error, and report it nicely back 
to the user so they can fix it. (I recall a demo with Cocoon 1.8.x that 
had something like this...)

Hmm, these three things might do it. the new serializer would work for 
editing, the Tidy-like class work work for either storing the data as 
xml, or just viewing it as xml. I think I have an idea on how to do the 
serializer, but it wouldn't rely on a transformer like the current one. 
I looked at the code for jTidy and there's a ton of classes, so I've yet 
to fully comprehend how it works, it might already be able to do what i 
want, and like I said I saw something similar to 3) a year or so ago...

ok, that's my thoughts...

Justin

Re: Keeping HTMLSerializer from altering markup?

Hmmm... well I'm getting some strange things happening now. The cdata

When it was working the textarea tags were not escaped.

For now, I made a small hack (inserting some default text) so I can

Re: Keeping HTMLSerializer from altering markup?

[Justin Fagnani-Bell]

Yes! finally.

Here's what I did. I added a  tag around my  tags in my 
stylesheet, then put cdata in my serializer definition. Now 
even when the textarea has no text the tag doesn't get touched. The 
browser just ignores the made up cdata tag and everythings fine.

I tried what you suggested, (adding textelement) but when the textarea 
contained just text (no markup) i'd get something like this: [CDATA[some 
text]] in the text field.

Thanks everyone.

Re: Keeping HTMLSerializer from altering markup?

[Justin Fagnani-Bell]

Thanks for the replies guys, unfortunately I'm still kinda stuck.

I tried the xhtml serializer (which is really an xml serializer) and the 
xml serializer They almost work, but not quite. First, Mozilla 1.0 won't 
render tables correctly ( bgcolor attribute, though Chimera renders 
fine) for some reason. More importantly they turn an empty set of tags 
(ie. ) into one tag () which is fine for 
most tags, but for textarea (in Mozilla at least) it causes the text 
field to be filled with the contents of the html file after the 
 tag to the end of file.

I'm not sure whether  is correct in XHTML. If it's not then 
this could probably be called a bug in an xhtml serializer, even though 
this makes sense in terms of xml. If it is correct (which i suspect) 
then it's a bug in Mozilla. Either way it's a PITA.

One solution might be to turn off combining empty tags in the xml 
serializer. Is there a way to do this? There's no docs on the 
cofiguration parameters for any of the serializers, and I'm a little 
confused by the source. It looks like XMLSerializer, and HTMLSerializer 
(through AbstractTextSerializer) get a transformer to do the conversion, 
and pass a bunch of parameters to it. I assume method is the xslt output 
method, but what is cdata-section-elements? Could it be of use to me 
here?

Another thing I tried was using a TextSerializer, with the mime-type set 
to text/html. I figured that for text output it wouldn't mess with the 
tags, only problem was that mozilla wouldn't render any of the tags, 
just the text. This is probably because of a namepsace or dtd issue and 
I'm gonna try to fix it.

Justin

oh yeah, on more thing that may be important. I'm using cocoon 2.0.1. It 
didn't include an xhtml entry in  so I copied it from 
2.0.3. If the serializers behave differently that could be an issue, but 
I don't think I can upgrade right now. I'll see.

Keeping HTMLSerializer from altering markup?

[Justin Fagnani-Bell]

Hi list,

  I have a page with a form generated by Cocoon. There's a textarea in 
the form where you can edit some xml (possibly xhtml). Because the form 
is an HTML form I'm using an HTMLSerializer. But I want to keep the 
serializer from altering the markup in the textarea, because if it's 
xhtml content it will turn 's into 's. Then when the text is 
saved and you visit the form again, or view the page the text is on, I 
get a parsing error.

My xml fil looks somethng like this:


   
 
   Here's some text that will get messed up by HTMLSerializer
   
   Then I'll get an error.
 
   


I use an xslt template to turn this into my form that looks likt this:




I've tried a few things with no luck so far. I added a 
xmlns="http://www.w3.org/1999/xhtml"; attribute to the text element 
hoping that HTMLSerializer would then leave it alone, but my stylesheet 
won't copy the text now. I tried copying the xml serializer component in 
, renaming it "xhtml" and changing the mime-type to 
text/html, but the browser wouldn't render it.

(Along a similar line, I was trying to use jTidy to turn html into 
xhtml, in case the user didn't enter well-formed xml. But I'm dealing 
with html fragments and jTidy kept wraping everything in , 
etc...)

Any ideas?

Thanks,
   Justin

Initialization and background threads

[Justin Fagnani-Bell]

Hi List,

   The web app I'm developing with Cocoon needs to initialize a few 
things at startup and perform some tasks in the background like database 
cleanup, checking for mail, automating site updates. Is there a good way 
to integrate this with Cocoon?

For the initialization, I'm reading in an XML file to create resources 
available to my Cocoon components. I'd like to use the same parser 
configured for Cocoon. I've though about adding something like this to 
cocoon.xconf:


   load-class
   MyClass


and using a static initializer to perform the initialization and start 
the background thread, but I don't see how I could get access to the 
Cocoon environment. I'd like to be able to access components and 
resources through Cocoon.

Thanks,
   Justin

If I'm using cookies for session management will it just maintain the 
session if sessionMode=true, or is sessionMode only for
URL encoded sessions?

How to use Redirector...

[Justin Fagnani-Bell]

Is there any documentation on how to use either the Redirector passed to 
Action.act() or the sitemap  tag? I've used redirect-to 
successfully but I would still like some documentation to make sure I'm 
doing things correctly. I can't find anything in the cocoon docs and the 
api docs don't say much.

I'd also like to use the Redirector object in Action, and I assume it 
works the same (or that the class implementing the tag is a Redirector), 
but I'd like to know more. What does sessionmode do?

Any suggestions?

Thanks,
   Justin
