RE: Time to go back to JSP. Cocoon just isnt ready.

[Artur Bialecki]

Cocoon is ready and it has been for a while. We've been using cocoon
for interface to our application for last 2 years and deploying it in *very*
large companies. We have 1000+ XSP talking to EJBs and I never encountered
the problem described in the bug you pointed out (1.7.3 - 2.0.3 releases).
JSPs are like a toy car that’s "simple" to push across your living room, but
if
you want to get somewhere real you have to invest time in learning to drive
and get behind the wheel of cocoon.

I do agree that the docs need improvement. They are much better though then
in the olden days.

Subject: Time to go back to JSP. Cocoon just isnt ready.


I have reluctantly come to the conclusion that cocoon is not ready for
professional development. Unlike tomcat, or Ant, this product has serious
things blocking its use in production systems. I personally am completely
and utterly stopped by the classpath bug indicated here:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16580. Just another
symptom of a product that needs more work to be used in professional
products. That coupled with the lack of documentation makes the package
difficult at best. I will possibly be back in a year or so when this
technology has gone somewhere. This is assuming it is still alive by then. I
have seen a plethora of new people come on this list and then just vanish.
That doesn't bode well for its reputation. I don't want to take this step
and throw away two weeks of work but the fact is that I also don't have time
to wait for such massive bugs to be fixed and to spend another two weeks
swimming through poor debugging tools. Its a massive bummer to me but in
order to be true to myself I cant see alternatives. The fact is that however
flawed JSPs are, I can crack together JSP pagers 40 times faster than cocoon
pages. When it comes to deadlines, major bugs like this just stop a product
cold. Anyway, Ill stop rambling now.

Comments are invited.

RE: XSP : control structures

[Artur Bialecki]

There is nothing like that in XSP. I'm sure most people here
will tell you to use transformers, actions, or better yet flow
from 2.1. Since I had XSPs left over from 1.x version and
I like having data access, logic and error handling in the same
place (the XSP) I developed my own logicsheet to that has several
control structures. There quite specific (in error handling) to
our product so it would take some work to make them generic.
Also don't know if the dev people would accept it since: "XSP
should at most be used to transfer data from request attributes
into to the SAX stream." 

Also you should be able to use the xslt control structues in your 
XSP (with its xsl: namespace and declaration in xsp:page)
but I haven't tried this.

RE: xinclude performance issues,

[Artur Bialecki]

The XIncludeTransformer parses the included file into DOM,
and then streams the included part back into SAX. In my case
I have 1000 pages including parts of 10 others so I hacked
the XIncludeTransformer to keep the DOMs of those 10 pages in
memory. This is not the best solution but it's fastee, 
you should probably look at aggregators instead
(I had to deal with legacy XSP from Cocoon 1.x).

RE: form encoding UTF-8 / ISO-8859-1

[Artur Bialecki]

I looked at the javadoc for java.lang package (jdk1.3.1)
and java.nio.charset.Charset (jdk1.4.1) and it
looks like the UTF-8 is the correct name.

I have a feeling setting the container encoding to ISO-8859-1
is what fixed your problem.

Another word of caution is the java.net.URLEncoder class that
doesn't play nice with UTF-8 in pre 1.4 jdk version.

RE: Looking for help in the upcomming release

[Artur Bialecki]

The "build docs" seems to work fine. I got
"BUILD SUCCESSFUL" and all the docs seem to 
be there. 

As to the installation there are no instruction for
installing with Tomcat 4.1 so I just dropped
the cocoon.war into tomcat's webapp directory
(as specified by 4.0.1b1 instructions)

UTF-8 character encoding

[Artur Bialecki]

It seems that the only way to output request parameters
encoded with UTF-8 is to call request.setCharacterEncoding("utf-8");
on **every** request. Is there a better (simpler) way of achieving
end-to-end UTF-8 for the whole site?
Also, setting encoding will call the decode() method
on every access to request parameter which for me is overkill
since my container alredy does the decoding.

The problem manifests itself by replacing single Ü character
with Ü. 

JDK 1.3.1, C2.0.3, win2k, Saxon 6.5.2

Thanks,

Artur...

RE: Redirect in XSP

[Artur Bialecki]

Hi Joerg,

I was under the impression that once generation started
sax events go through tarnsformers and a serializer and
data is sent back to the browser. So if the 
is emitted after the tags that caused  to be sent
to the browser this would not work.

Would it?

How would this work if half of my page has already been
sent to the browser including the  tag?
Please clarify.

RE: Redirect in XSP

[Artur Bialecki]

Witold,

First of all processing of XSP is done by a Generator
which is part of pipeline *execution*. This means that
it's too late to redirect at that point since some data
might already been sent back to the browser (depends 
on the size of your serializer buffer).

You should only redirect during pipeline *setup*,
before any generators are called.

Assuming you using Cocoon 2.0.x you probably want write
and Action that checks for condition that might cause
redirection and return it as a sitemap parameter
and use  before generation of your
XSP.

Witold & Neil

Look at ServerPagesAction.java and action.xsl
in cocoon source.

Unfortunately (well not really) I started with Cocoon 1
and had *lots* of man-hours invested in XSP pages that
talk to EJBs and have lost of logic (in logicsheets).
When I moved to Cocoon 2.0.3 I did not want to redo
all of the XSPs because: 1. I had no time, 2. Cocoon 2.1 is
coming and it has cool new things as well as it changes
some other things again.
So now I have an action that processes XSP and stores
results in request attribute. This action does many things
including handling any errors which involves redirection.

Currently I use external redirection from that action
but I would like to redirect internally instead. So if
there is a way of doing internal redirection from the 
act() method please let me know.

Thanks,

Artur...

ForwardRedirector ???

[Artur Bialecki]

Is there a way to redirect internally (without going back to the browser)
from an action? Actions get a Redirector but it is a SitemapRedirector
that calls HttpEnvironment.redirect(). Is there any way
I can get a ForwardRedirector in my action.

Thanks,

RE: dynamically choosing an action at runtime

[Artur Bialecki]

Check out the   "Calling resources" on this page
http://xml.apache.org/cocoon/userdocs/concepts/sitemap.html
Maybe you can organize the 'meat' of your pipeline as
as a resource and just map:call it from your main pipeline.

RE: Cocoon and EJB

[Artur Bialecki]

I've been using Cocoon 1 and 2 with EJBs for last
2.5 year for enterprise size application. One advantage
I had was that I decided to use cocoon from the beginning.
so my EJBs can present themselves as XML which makes for
easy insertion into the XML stream.
The biggest problem I had was handling of errors that
EJB methods can throw and are handeled by
redirecting to another page. The way I handle this
is that I have an action that processes the XSP
and store it in a request attribute. The XSP contains
tags that access my EJBs and define error handlers.
Once XSP is processed without errors I call a simple
generator that reads the resulting XML from the 
attribute. 
I only use transormes for xincludes, i18n, and
changing data centric XML representation to GUI
centric representation for complex data models.

This might not be the best way of doing things
but it works for me.

 usefull when you write your own logicsheets. 
It's contents are the first thing in the generate() method
of generated page.
I found it by looking at xsp.xsl and
session.xsl in cocoon source.

RE: Can anybody solve this?

[Artur Bialecki]

Can you move your  before the  tag?
Or try this

   String productId = request.getParameter("productid");


although the init-page tag might only work as a child
of .

Pool statistics

[Artur Bialecki]

Is there any way to obtain statistics on component pools
used by cocoon (2.0.3). Also, are component pools soft or
hard limit by default?

Is internal redirection from Actions possible?

[Artur Bialecki]

Is there a way to redirect internally (without going back to the browser)
from an action? Actions get a Redirector but it is a SitemapRedirector
that calls HttpEnvironment.redirect(). Is there any way
I can get a ForwardRedirector in my action.

Your mistake was using cocoon.xconf from src/webapp/WEB-INF.
For some reason it doesn't define the compiler parameter for

Someone should fix this.

can you elaborate this in a little more details? I don't quite get what you mean by 
that, sorry 


All I'm saying is that logicsheets which are used during
generation of server pages are not the best palce to
call J2EE business logic. EJBs can throw many exceptions
and by the time you get to generation all you can 
do is transform on your errors so in the simplest form
your stylesheet must be able to handle all possible errors
generated on the given page. I consider an internal redirection
much better approach to handling errors, e.g. On error I can
redirect back to the original form. Gets even worse if you
EJBs have input on which stylesheet to use, e.g. If inventory item
foo (business object) has stylehseet hint then use it, otherwise
use default_inventory_item.xsl.
Way I can get around this is to process my XSP which uses logicsheets
with calls to J2EE beans before generation starts.

Cocoon right now (2.0.3) has no good way to handle 
errors generated by J2EE business logic. I have 
logicsheets that access J2EE beans but I have
to process my XSP with action before the generation
starts so I can do something real whith errors.

RE: XPath selector or XPath matcher

[Artur Bialecki]

If you want to do it with the current system you
can:
1 - create an action that processes you XSP and stores
  it as DOM on the request, similar to ServerPagesAction
2 - create an action that given XPath will find the
  node/attribute in a stored DOM and return it's value
  as a sitemap parameter.
3 - use the sitemap parameter for your logic.
4 - have a generator that serializes the stored DOM
into sax events, similar to SessionAttributeGenerator.

To solve the problem I had to change my web.xml so the work-directory
is set to WEB-INF/work instead of /WEB-INF/work. The upload-directory
and cache-directory work fine the old way.

And yes iPlanet == BIG SUCKAGE

Problems with 2.0.3

[Artur Bialecki]

I'm upgrading from 2.0.2 to 2.0.3 and now I get the following error:

ERROR   (2002-08-09) 11:15.00:338   [sitemap] (/NASApp/dfc/common/controlpanel.xml)

Is the / in front of WEB-INF what's causing the problem?
Any ideas how to fix this?

I also noticed that src/webapp/WEB-INF/cocoon.xconf
is missing "compiler" parameter for 

(iAS6.5, win/solaris, jdk1.3.1, cocoon is one of many servlets in ear(war))

Thanks,

I found many problems with the iAS stability and compliance. I would suggest
moving to something else if you can.

RE: Cocoon status page ??

[Artur Bialecki]

I don't use the cocoon.war, I define cocoon as one of the servlets within
my application and throw all cocoon related jars in my WEB-INF/lib.

Cocoon is working fine I just can't get to the status page using
/cocoon/status because of my mappings.
Someone mentioned a "status" generator which I'm looking into
maping to something like cocoonstatus.xml

I agree as well. It's nice when you have time to tinker, wait
for useful replies from the mailling list or search the archives and
wade through messages that most likely talk about version you're not
using. It's nice to have time to look at source code and hope what
you learn will still hold in the next version. Unfortunately,
a lot of developers have very little time and don't want
to spend all of their "well wasted time" on Cocoon. This is not
about open-source vs closed-source, this about making Cocoon
usefull to everyone. Yes, I know I can help by pathching, writing
docs, answering questions on mailing lists (I sometimes do the last one),
but that requires time that I, and many other developers, don't have.

New features/design is nice but I'm already affraid I will have to
go through same HELL moving from 2.0.2 to 2.1 as I did when moving
from 1.8.x to 2.0.2. Please tell me that I'm crazy and that
all I'll have to do is drop in a new jar(s) and edit my cocoon.xconf.
I'm not crazy and I'll probably have to do a lot more and 
there wont be a migration guide to tell me what to do.

Cocoon is great, cocoon developers/community is great, but
I'm tired of explaining to VPs and clinets that Cocoon's
benefits outweights its lack of documentation and API stability.
These people would like to know that it will not cost them
3 months of extra development time, because their in house
Cocoon expret was hit by a bus.

So, IMO if you want Cocoon to succeed in medium/big business
all you have to do is write lots of helpful docs. The upcoming
books are a good start, but thinks like API JavaDocs with
actual comments for each package/class/method and installation
migration and user docs need to be released with each version.

RE: Logging and Form Validation

[Artur Bialecki]

This is what we do for client side validation.
WARNING: requires javascript but my clients are not
"regular" web users.

For my app I provide validation in my XSP, eg:
  

  
   ^$|^[0-9a-zA-Z_]+$/ig
  
  


  
   ^$|^[0-9a-zA-Z.,_\\-]+\\@[0-9a-zA-Z._\\-]+\\.[a-zA-Z]+$/ig
  
 
   

so for each from field that needs to be validated I have 
 with id of the form field and one or more rules.
I also provide validation template that reads the /page/validators
and creates validateAndSubmit() javascript function that
validates all fileds specified in XSP.
Form filed name must match validator names but that's easy.
I define validators in XSP since some of them are based
on DB queries.

This works great for us.

We also validate on server side with automagic annotation
of errors and from field repopulation since not everything
can be validated on the client side (eg: does city Bumbomie
exsits?) so I our clients ask for support for javascripless
browers (which they wont) it will still work.

Just my 2 cents.

Artur

RE: Migrating from Cocoon 1 to Cocoon 2

[Artur Bialecki]

Look through the archive. As I said in one of my post
Migrating from Cocoon1 to Cocoon2 is like converting
a gorilla to a submarine.

Took me 6 weeks to move our (complex) app from
C1 to C2 (I consider this VERY long time). I had to
hack Cocoon and Saxon since Xalan didn't work at all with my
complex XSLTs.

Good luck,

I use the servlet container that is part of iAS not the one that
comes with iWS. I know in iAS 6.0 WEB-INF/lib was ignored so I don't
have anything in there, I add my libs to the iAS classpath (using registry).
Also, I don't explicitly call ServletContext.getResource() anywhere
in my code, cocoon does most of the resource finding for me, webserver
takes care of images and static docs (for now).

It very well may be. Again, other than putting all cocoon related libraties at
the beginning of the iAS classpath I didn't have to do anything special.
It's possible that cocoon detects this resource problem and uses the 
BootstarServlet automagically.

RE: iPlanet 6.5 + Cocoon - is there still problem with serv;et container?

[Artur Bialecki]

iPlanet DOES suck, but so does every other j2ee container.
As with all infants you have to do exactly what they want
or they will cry/barf and don't forget to clean up their shit.

Don't know exactly what problem you're talking about but
I have Cocoon 2.0.2 (with Saxon 6.5.2, jexen) running under iAS 6.5
on w2k and Sol8. I don't remember running into any problems.

RE: help with XSP, maybe actions

[Artur Bialecki]

In your pipe ine you need to specify serverpages type for the
generator, otherwise it will use the straight file generator.
So try this 
Also you don't seem to have any transformes to convert the 
generated xml to html/xhtml before you serialize it, you may
want to add that too.

RE: cannot deploy on JBoss 3

[Artur Bialecki]

I've tried using cocoon2 with JBoss 2.4.4 and Tomcat 4.0.3 and
couldn't get it to work. When I installed Tomcat 4.0.4b2 everything
worked. I think some other people on this list also had problems
with 4.0.3.

Subject: cannot deploy on JBoss 3


Hi,

I'm trying to drop the cocoon.war file into the deploy directory of JBoss3 RC1, which 
uses Catalina (TomCat 4.0.3).

But I get the following error (see below) - NullPointerException trying to put the 
default context.

I've tried just deploying the .war file which fails.
So I've tried the install instructions 
(http://xml.apache.org/cocoon/installing/index.html) even though JBoss 3 isn't 
mentioned, for
TomCat 4.0.3 reference but I still get the same problem.
Basically, I tried adding xerces, xalan, xml-apis, batik-libs to the 
catalina/common/lib/ directory - but no joy here, so I also
unjarred cocoon, edited WEB-INF/web.xml and added the extra-classpath param, re-jarred 
it but this made no difference.
I also tried the Catalina reference, removing crimson & jaxp, adding xml-apis to 
jboss/lib and adding it to the classpath when
starting JBoss.

I also tried adding the following to cocoon.xconf, again with no difference:


I also trawled through the mailing list archives but found nothing that worked.

Does someone have it working and can point me in the right direction? What step have I 
missed?

Many TIA...I have battled for a couple of days with this, but I am running out of 
things to try.

Charles

RE: cocoon actions

[Artur Bialecki]

The example you provided only declares the actions. In order
to use them you have to use them in you pipelines using
the  or using the cocoon-action request parameter
(check the action user docs).

Also, examin your generated sitemap java file sitemap_xmap.java
probably in your appservers WEB-INF/work directory.

Returning null from an action means that that action failed,
you might want to return an empty Map instead.

RE: Question: what is {session-id} ? in a sitemap.xmap ?

[Artur Bialecki]

>From what I know, basically {name} is a representation of
a sitemap parameter which are used by sitemap components.
For example, if your pipeline wants to call another (resource)
pipeline you with a target parameter you would do it this way

 


now in your "simple-page" pipline you can access that target
paramter with {target} so you can have:
  
 
 

 
 
  

Also, if you implement actions the return of the act() method
is a map that will be added to the session paramters.
In your action of you do
sitemapParam.put("session-id", getSessionID()); then
in your pipeline you can do

Hope this helps.

RE: multiple XSLTs for the same XML

Well then, I think you can use a reference
to another pipeline:

and have that pipeline aggregate your xslts
with .

I haven't tried this before, so good luck.

RE: Problems with Saxon (6.5.2) and resolver (Cocoon 2.0.2)

[Artur Bialecki]

Also, saxon 6.5.2 and 7 has a bug with identity transform
because of bug in DOMDriver.
So, if you're using XPath (eg, xinclude transformer) things
might not look the way you expect them to.

I told the author of Saxon how to fix this bug, but haven't
heard anything back.

RE: upgrading to Cocoon2 and debugging

[Artur Bialecki]

Porting from Cocoon1 to Cocoon2 is 
like converting a gorilla to a submarine.
If your project is small than I would read up
on Cocoon2, rethink your approach and start from
scratch, otherwise read on.

There a quite a few change you have to do to XMLs. 
tag libs request, response, etc. are now xsp-request, xsp-response,
etc. Also their namespace uris have changed so now you must have:
http://apache.org/xsp/request/2.0";>
and same for response, etc.

If you used xspCurrentNode and its friends than you have to
rewrite your XMLs to use SAX contentHandler instead.

The fp taglib is not in C2, other taglibs have changed too.

If your XMLs did redirection or changed stylesheets on the fly
than you might need to write some Actions.

  there are sitemap.log error.log core.log and access.log probably

RE: iPlanet + Cocoon: did anybody try?

[Artur Bialecki]

I've been runnig Cocoon 1.8.x on iAS 6.0 through 6.5 for last
couple of years. I'm currently porting our stuff to Cocoon 2.0.2
which will run on iPlanet 6.5.

I haven't worked much with Weblogic and Websphere but for large
applications both iPlanet and JBoss are f'ed up in their own
unique way. With JBoss you at least have the code,
with iPlanet you're very lucky if your bug gets fixed within 8 months.
iPlanet breaks J2EE in several palces so be ready to 
wrtie workarounds. I don't know about 6.5 but previous version
used some hacked version of Tomcat for the servlet container.

RE: Custom Database Action

What exactly is the problem. The action documentation
has enough stuff the get started. Look in the source code
cocoon-2.0.2/src/java/org/apache/cocoon/acting for examples
of actions. Remember to define your actions in the sitemap
before you use them. Make sure that the classloader that
loaded cocoon can find your action class.

Saxon Xinclude problem

[Artur Bialecki]

I have a problem with Saxon 6.5.2 and Xinclude transformer.
I get the following:

java.lang.NoClassDefFoundError: org/apache/xpath/XPathAPI
at 
org.apache.avalon.excalibur.xml.xpath.XPathProcessorImpl.selectNodeList(XPathProcessorImpl.java:65)

Do I have to keep xalan.jar for the XPathAPI or do I use something
else. How can I get this to work.

Need to replace xalan

[Artur Bialecki]

Ok, xalan 2.3.1 and xalan head is horribly broken and from
the number of bugs I doubt will see a working vision this year.

What other XSLT processor can I use that's JAXP compliant, has
node-set extensions and is easily integrated with Cocoon2.

This would make it more consistent with wildcard matcher and

Maybe this should be a general rule for all matchers that
parameter {0} is allways the whole matched pattern.

Request vs HttpServletRequest

[Artur Bialecki]

  Life is hard for people porting from C1 to C2, so
  many things have changed. Why, oh why?


Let's asume I'm a crazy person who uses Cocoon servlet
with other servlets and all these servelts share utility
classes. Some of this utilities use to take
HttpServletRequest as a parameter, but when I moved
to C2 I had to changed them to take org.apacheRequest
instead (lots of my XSPs use these utilities and doing
(HttpServletRequest)objectModel.get(HttpEnvironment.HTTP_REQUEST_OBJECT)
everywhere would be a pain).

In order for my other servlets to work I have
to convert HttpServletRequest to cocoon HttpRequest,
but the constructor for HttpRequest is protected so
forget that. I guess the only option is to create
HttpEnvironment and pass it all the crap that it needs,
get the Reqeust out and throw it all away.

Is there a simpler/smarter way to get cocoon HttpRequest
from HttpServletRequest?

Thanks,

Artur...

RE: Cocoon use

[Artur Bialecki]

In my company cocoon is used as the only user interface
to enerprise/network management/fulfillment (OSS,BSS) system
that includes order entry/management (workflow), inventory,
activation, etc. Since we use XML at the core of our J2EE
application and we need the ability to "brand" our interfaces
Cocoon is perfect for the job. Ability to output to multiple
devices and i18n allows for future expansion. I've written
logicsheets (tag libraries) to communicate with our j2ee beans,
so now even our gui developers can create/modify our XSPs.

Also because of MVC separation, I can hand-craft XML page
and give it to gui developer so he/she can start on the XSLT
while I create and test XSPs, java, tags, whatever to generate
that XML.

RE: Simple installation problem?

[Artur Bialecki]

In some cases if the cocoon.jar (and its libs) are loaded from the lib directory
they cannot see classes from the applications. Try putting cocoon.jar and its
core libs in the WEB-INF/lib directory of you war. Or you can jar up your custom
classes and throw that jar in tomcat's lib (where cocoon.jar lives).

I had this problem witch C2.0.2, Tomcat 4.0.4b2 and JBoss 2.4 and since
more than one app used Cocoon I had to go with the second option.

Hope this helps.

RE: Migrating DOM based XML generators

[Artur Bialecki]

See if org.apache.cocoon.xml.dom.DOMStreamer will do the job for you.
It is used by org.apache.cocoon.components.language.markup.xsp.XSPObjectHelper

[C2] How do I import form logicsheets ???

[Artur Bialecki]

I useto to this in C1 for imports in my logicsheets (not XSPs)


  

  


  dfc.cocoon.*
  dfc.cocoon.ErrorWrapper
  dfc.servlet.MainMenu

 
  
 

but this doesn't seem to work in C2. My generated Java
files are missing both package and class names,
and I hava dangling dependencies like this:   
 dependencies = new File[] { new File("

What is the right way to import packages in C2 logicsheets.

Thanks,


Artur...

RE: Why isn't Cocoon making into the commerical world?

[Artur Bialecki]

Cocoon is making into comertial world. My company uses it
for all iterfaces to our sizable product (over 1000 XSPs).
We started with 1.7.4 and moved to 1.8.1 and now I'm trying
to move to 2.0.2 (I hope performance will be better).

Where Coccon is lacking is documentation, documentation, and
documentation. I find that whenever I'm looking for something
5% of the time I find it in Cocoon docs, 40% of the time I find
it from the mailing list archives (I wish I could use deja.com
for my searches) and rest of the time is code surfing.

Also some push into comertial J2EE providers should be made.
iPlanet App Server included cacoon in one of it's version but
I think the new one (6.5) will come with Struts.

Anyways, it's a great engine I just wish I could spend less time
looking and more time developing.

[C2] Best palace for redirection in case of error

[Artur Bialecki]

Hello all,

I'm in the process of migrating from C1.8 to C2 and I'm writing
some actions to save form data. If saving this data generates
exceptions I redirect to predefined (in form XSP) page based
on type/id of the exception.

My question is what is the proper way to do that redirection
form action? Should I use the Redirector(?), or just
grab the HttpServletResponse form the objectModel and use that,
or return some sitemap params and do magic there.
Since I can't find any info on what the Redirector is/does
and I'm only a student of the sitemap magic I leaning towards
the Response.

Thanks,

Artur...

RE: Turning XSPs into Generators (Why?)

[Artur Bialecki]

Can you explain how this makes things faster, I assume
XSPs are not convereted to Java and complied each time
I access given XSP. Is the performance difference in
sitemap processing, cache lookups, etc. If so how much.

Thanks,

Artur...

Is there a migration guide (help) anywhere for
migrating from Cocoon 1.8.* to 2.0?
