Yes, you're right ... too harsh.
I'm really just a newbie, but speaking as one, I think that 2.1 was a much
nicer experience out of the gate, which is pretty damn important for an
application to gain wider acceptance.


BTW, there's also a different viewpoint:



For us, as a project depending on Cocoon, it is crucial that Cocoon 
doesn't cling to "dead" (as in language) concepts and frameworks as XSP 
and Avalon, however proven and stable they may be. To attract new 
community members, it's very important to keep looking beyond one's own 
nose and stay in touch with current trends in the Java world. Putting 
"Based on Maven and Spring" on your homepage sounds much better at the 
moment than "Based on Ant and Avalon". And we shouldn't be afraid of 
learning – familiar concepts often seem to be easier to understand than 
new ones.




Just my $0.02.

Hi Derek,

I agree from a *marketing* perspective that putting buzzwords 
on your site is a way to attract new users - especially those who
might otherwise be going to .NET or Ruby-on-Rails - not that I mean 
to  imply the developers are doing this for that reason alone.  

However, there is also such a thing as a "legacy" application; 
while you (or others) might think that languages such as COBOL,
FORTRAN, Pascal etc are "dead", I can almost guarantee you 
there are millions of lines of code in those tools being written
or maintained every year (C# notwithstanding). 

There are many of us who have been using Cocoon for many 
years now, and I would really hate to think we'll just be dumped 
because some new ideas or support frameworks have emerged.


do you have the feeling that the 2.1 branch is not sufficiently 
supported anymore? If I understand Betrand correctly, it is officially 
in maintenance mode and it is not planned to cease support. We (the 
Lenya community) are certainly going to need it for another couple of 
years, so we'll be bound to maintain it.




Personally, I'd also like to see the documentation develop and
mature a little more - there are certainly *lots* of "getting started"
questions in the ML about 2.2 - and a book or half would also 
provide some reassurance that a solid new ship is ready for all

types of sailors.

So yes, I am prepared to learn - no doubt I will have to - but it
does not yet feel the right time for what appears to require a 
significant upheaval.


Sorry if my mail caused any offence or could be taken personally, that 
was not my intention. I only wanted to express the viewpoint of another 
type of Cocoon user – the projects which depend on it.


Thanks for your reply!

[C2.2] StandaloneServiceSelector not found

[Andreas Hartmann]

Hi Cocooners,

when debugging in Eclipse, I get an error that some Avalon 
configurations could not be read due to the missing 
StandaloneServiceSelector class. It affects the configurations of the 
faces and taglib impl modules.


Is the configuration outdated? I couldn't find the 
StandaloneServiceSelector class anywhere. Or did I miss something?


TIA!

So it looks like you are hitting something rather old that have been already 
renamed. I don't have a time to drudge Git
a little bit more but still I hope this gave you some clue how to dig into this.


thanks a lot for this info! For the moment I have removed the offending

a closer look at the issue.

[2.2] Cannot resolve reference to bean SourceResolver in unit test

[Andreas Hartmann]

Hi Cocooners,

I'm trying to get some tests to run which rely on a components which 
uses the source resolver.


The component is declared in lenya-core-ac-components.xml as follows:

  
ref="org.apache.excalibur.source.SourceResolver"/>
ref="org.apache.lenya.cms.publication.Repository"/>

  

In my (TestClassName).spring.xml I reference the bean configuration file 
like this:


  resource="classpath:META-INF/cocoon/spring/lenya-core-ac-components.xml"/>


But I get the error

Cannot resolve reference to bean 
'org.apache.excalibur.source.SourceResolver' while setting bean property 
'sourceResolver'; nested exception is 
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean 
named 'org.apache.excalibur.source.SourceResolver' is defined



Could this be a problem of a missing dependency? The 
cocoon-template-impl tests seem to rely on components which use the 
source resolver as well, and I couldn't find a difference in my 
configuration.


TALIA!

For the record, I "solved" it by adding an .xtest file with the

[2.2] Test configuration

[Andreas Hartmann]

Hi Cocooners,

according to http://cocoon.apache.org/636_1_1.html, for each unit test 
class one or two configuration files (.spring.xml and/or .xtest) have to 
be created. This works, but since the files contain a lot of boilerplate 
declarations (roles, source factories etc.) a lot of redundant code is 
created. At least the .spring.xml files can work with includes, so one 
can collect the declarations in a single file. But I don't know if the 
.xtest files support something simliar.


Is it really necessary to create these files for each and every test class?

TIA for any hints!

[2.2] Spring class loading issue: WebAppClassLoader vs. ResourceStoreClassLoader

[Andreas Hartmann]

Hi Cocooners,

in my C2.2 application, I have two modules "usecase" and "acusecases", 
with acusecases depending on usecase. usecase is a block, acusecases isn't.


A bean in acusecases shall get a reference to another bean defined in 
acusecases. The class of this bean is declared in usecase.


Now I get the following exception:

org.springframework.beans.TypeMismatchException: Failed to convert 
property value of type [org.apache.lenya.cms.usecase.UsecaseView] to 
required type [org.apache.lenya.cms.usecase.UsecaseView] for property 'view'


Since the class is the same, the classloader is the source of the 
problem. Using the debugger I found out that the bean (from the 
acusecases module) is loaded using a WebAppClassLoader, but the class

(from the usecase module) is loaded using a ResourceStoreClassLoader.

Firing up Jetty with 
-Dorg.mortbay.jetty.webapp.parentLoaderPriority=true doesn't help.


Any hints how to solve this issue?

TIA!

The issue could be resolved by removing the usecase block from

[2.2] Why are some projects not installed?

[Andreas Hartmann]

Hi Cocooners,

when I build the current trunk, some projects are not installed, for 
instance


* cocoon-serializers-charsets
* cocoon-serializers-impl
* cocoon-validation-impl
* cocoon-chaperon-impl

The artifacts also don't seem to be available in the online repositories.

Since I use them in another project, I have to invoke "mvn install" in 
these individual project directories. Is this intended? If not – what 
needs to be done to solve this issue? Or is something wrong with my setup?


TIA!

Hi Andreas,

Try
mvn -P allblocks

this will enable build process for all blocks. By convention blocks that are 
disabled by default are those not
officially released.


thanks a lot – one minute ago I also remembered this, but the mail was 
already on its way, sorry for the noise :)



Any help on getting more blocks released is greatly appreciated.


Is there a documentation what needs to be done? I guess it's mainly a 
matter of testing?

This looks like a classpath issue but quite strange one.

How do you start your Cocoon application? With mvn jetty:run?


Yes, I'm using jetty:run. But I have now found the source of the 
problem: The offending change was enabling a block in my application 
that had a dependency to cocoon-batik-impl. This module uses Rhino 
1.5R4.1, but the flowscript module needs 1.6R7. I guess the Continuation 
class didn't exist in 1.5R4.1 yet.


Anyway, after adding the exclusion declaration to the cocoon-batik-impl 
POM to avoid the transitive dependency, it works again:



  batik
  batik-script
  

  rhino
  js

  


Shall I commit this change?

Re: Passing "parameters" to mounted sub-sitemaps

[Andreas Hartmann]

Hi Klortho,

Klortho schrieb:

I'm sure this is a dumb question, but I'm kind of a newbie, and have just
spent hours looking for the answer in various books, and searching this
forum, and can't find it.

I'm trying to vary the look of my final output depending on where the source
files are stored.  I have a resource-exists selector that decides whether to
mount a sub-sitemap from one location or another.  Then, I want to pass
something down to the sub-sitemap so that it can pass it along to the
stylesheets, so that I can get a different background color depending on the
source tree's physical location.

I tried pretty brain-dead ideas like using  in my
parent sitemap, and then a parameter selector in the child, but then I read
that the parameter selector is only for parameters from actions or for url
segments from matchers.

Isn't there a canned action that will just let me set a parameter of my
choosing with a value of my choosing?  Or, what's the right way to do this?


how about something like this?

Main Sitemap:


   (location)

  


  

  



  



Sub Sitemap:


  …

What exactly do you mean with "send to the sitemap"? Usually the sitemap 
is the entry point into processing, so you rather pull a parameter from 
a Java class (e.g. via an InputModule.)


Or are you calling an internal pipeline from a Java class via the 
SourceResolver?

Good stuff, thanks!  You gave me the general idea -- an internal redirect
with the parameter stuffed into the internal URL.  I had to change your code
a bit to get it to work, here's what I came up with:

Main sitemap:


  

  

  
  

  
  
  

  

  

  

Sub-sitemap:

  


  


  

It's pretty ugly, though, I think.  Isn't there a (relatively) easy way to
set, say, a request parameter that would be visible in the sub-sitemap?


I don't think it's that ugly – maybe the pipeline concept just takes a 
bit getting used to when you're new to Cocoon. IMO passing parameters in 
URLs is a good practise since this way you create a "pipeline API" that 
helps others to understand the code.


Another approach would be to attach the color value to the current 
request as a request attribute. AFAIK there is an action and an input 
module for this purpose.

The problem I am facing is that the pagetemplate is not always generated

E.g. pattern=”index.html”  or pattern=”main/released/product/xyz”

 

This causes that my css file is not found. No pipeline matched request:

Can’t I use some cocoon protocol that indicates that the file has to be

Re: Spring bean for action src

[Andreas Hartmann]

Hi Paul,

Hello,

We are trying to develop a Cocoon 2.2 application. We have developed a 
few 2.1 apps already. We are struggling with using a spring bean for an 
action.


We’d like to do something like:

(in sitemap.xmap)

  



  src="org.apache.cocoon.acting.HttpCacheAction">


  2

  

  



  

We define the bean in applicationContext.xml:




I'm not sure, but I think that has to read

class="com.gnb.forms.LinkForm">


Then you should be able to reference the action with the name "LinkForm" 
in your sitemap, without additionally declaring it in the 
 section.

Why ?


that could be related to the byte-ranges issue (incremental loading).

[2.2] Register cocoon:/ protocol to be accessible from Batik

Hi everyone,

I'd like to enable Batik to resolve cocoon:/ URIs in xlink references.

Just some quick questions to avoid spending time on a dead end:

* Is JNet [1] the way to go?

TIA for any pointers!

[2.2] LinkageError: WebAppClassLoader vs. ResourceStoreClassLoader

Hi everyone,

when using the RCL classloader I just can't get rid of this error:

java.lang.LinkageError: loader constraint violation in interface itable 
initialization: when resolving method 
"mypackage.BatchProcessManagerImpl.prepareListenerProcess(Ljava/lang/String;Lmypackage.Invoker;)Lmypackage.ListenerBatchProcess;" 
the class loader (instance of 
org/apache/commons/jci/stores/ResourceStoreClassLoader) of the current 
class, mypackage/BatchProcessManagerImpl, and the class loader (instance 
of org/mortbay/jetty/webapp/WebAppClassLoader) for interface 
mypackage/BatchProcessManager have different Class objects for the type 
mypackage/Invoker used in the signature



It occurs immediately for the first request after starting up Jetty. 
What could be the reason that the interface is loaded by the 
WebAppClassLoader and the implementation by the 
ResourceStoreClassLoader? Problably a Spring thing …


Any hints would be very welcome!

Thanks a lot in advance,

I just noticed that I had a similar issue before, but back then the 
interface and implementation were located in different blocks where one 
was loaded by the RCL and the other one by the WebAppClassLoader. This 
time both interface and class are located in the same block which should 
be loaded by the RCL:


mypackage.batch.service%classes-dir=../batch/target/classes

Any suggestions are greatly appreciated.

Re: Cocoon caching with multiple pipelines

Hi Robin,

It looks like the default generator is an extension of FileGenerator

what do you mean with "preceding pipeline"? What exactly does the custom 
FileGenerator use as the source? A hard-coded cocoon:/ call?




I also assume therefore
that the FileGenerator uses the incoming xml to build its validity
object and therefore spots that it has changed ?


No, the standard FileGenerator uses the validity of the source. The 
incoming XML cannot be used, since it would have to be re-generated to 
spot changes, which kind-of renders the caching mechanism useless. 
Typical source validities are based on last modification dates, 
expiration times and similar concepts. Example: If you pass a file URI 
to the FileGenerator, the last modification date of the file is used. If 
you pass a cocoon:/ URI to the generator, the validity of the 
corresponding SitemapSource (representing the result of the called 
pipeline) is used.

Re: validating xml

Hi Robby,

Hi all,

i've got an interesting use case where my starting point is XML data (could be 
1 single file, aggregated xml data, xquery results, ...)

 From this input I have to generate a DITA map and topics for which I have a 
map.dtd and topic.dtd which I  can use for validation purposes.


At some point in time during all transformation steps I have something like 
below simplified snippet immediately before I want to use the source-writing 
transformer.  I need to validate the map and topics before writing the files to 
disc.

   ...
   ...
   ...
   ...



I can't simply use the approach below
  (similar for map) 
since I still have an aggregated situation.

Did anyone ever have a similar situation and a solution for this?

Ideally the org.apache.cocoon.transformation.ValidatingTransformer could handle 
an optional xpath expression to specify which nodes to treat as rootnodes for 
validation.

Would this approach work?


yes, I assume that this approach would work.

A relatively simple alternative would be to modularize the page 
generation. The drawback is probably a decreased performance, especially 
when generating the initial XML is expensive.


1. Transform the initial XML data into an XML structure containing 
include tags for the single fragments which need to be validated (map, 
topic etc.)


2. The include transformation calls a separate pipeline for each 
fragment type; these pipelines contain the validation transformation 
step. Unfortunately, the initial XML needs to be re-generated in each of 
these calls.


Maybe this works for you?

Andreas

Resolving sources relative to webapp context

[Andreas Hartmann]

Hi Cocoon users,

I'm instantiating a custom component inside an action.
In this component, I want to resolve a path to a source:
resolver = (SourceResolver)
   manager.lookup(SourceResolver.ROLE);
source = resolver.resolveURI(configurationDirectoryPath);
This way, the source is resolved relatively to the
sitemap. Is it possible to get the source relative to
the webapp context?
The configurationDirectoryPath shall be defined in
cocoon.xconf, like e.g. in the EntityResolver.
I looked into the excalibur.DefaultEntityResolver class,
but didn't find a hint how the implementation is different.
Thanks in advance!

I think this is just because parameters.getParameter(String) throws an 
exception which you are not catching.  An alternative is to use the 
version with a default parameters.getParameter(String, String) which 
does not throw the exception.

Why it gave the specific exception you see I don't quite know.
It's because the declaration is in the class body and therefore
executed in the default constructor (which does not handle this

OK, this is a problem.

So you might be back to java code in this case as well, or maybe:

-get the list of images (DirectoryGenerator)
-write an XSLT transform using java.util.random to select one
You could also pass a random number (e.g, [0..100]) to the stylesheet
and calculate the image number:

No it's not. You just define the input module as many times as you need

Yes, but I think it should be possible to select the max number

Fair enough. Surely it shouldn't be hard to extend the random input 
module to be able to handle {random:10} or {random:20}? Assuming someone 
needs it. Or even {random:1-20}.
This would be nice indeed.

But in this special case - how do I pass the number of the files
found by the directory generator to the input module?
I guess the XSLT calculation method is quite suitable
for this very application.

There's a problem about this approach:

I can do this in xslt I think, or I could create a pipeline for

We (the Lenya community) recently discussed to write a

really make sense to make it generic, e.g.,
{path-to-context:{1}/{2}.html}

But this would require that sitemap parameters are expanded
inside input module calls (I don't know if this works).
Another possibility would be

{path-to-context:sitemap}

which would compute the relative path based on the
current sitemap URI (the URI as processed by the current
sitemap).

This is a good idea. It would make it easier, but slower
(depending on the processing - I don't know if this is
important for your application).
If you want to use SAX, you could do the following:

(1) A method for each element:

if (localName.equals(ELEMENT_ADDRESS)) {
startElementAddress(...)
}
else if (localName.equals(ELEMENT_NAME)) {
startElementName(...)
}
else if ...
(2) You could implement a set of handlers (ContentHandler
or a simplier interface) and register them for the
element names:
public void startElement(String namespaceURI, String localName,
String qualifiedName, Attributes attributes) {
handlers(localName).startElement(...);
}
public void endElement(String namespaceURI, String localName,
String qualifiedName) {
handlers(localName).endElement(...);
}

This is a good idea. It would make it easier,
Actually, I think it would make it a lot harder.
Yes, as far as this example is concerned, SAX is more than
sufficient.
But when the tree model fits your needs, you don't need
to build your own object model. Han is not yet very
familiar with processing XML, and I think for most newbies
it is easier to "think DOM" than to "think SAX". But of
course I could be wrong :)

For example: http://marc.theaimsgroup.com/?t=10710482681&r=1&w=2
I'd like to be able to access a file from within my webapp, but I keep
getting a "FileNotFoundException" because I'm not able to get the context
from within flowscript.
I think you could obtain a SourceResolver and resolve
the URI "context:///".

Re: Has anyone tried to generate the sitemap.xmap via WebGUI ?

I am currently developing a CMS based on Cocoon 2.1.4
The thing is changing contents is no problem.. but our users also want 
to add or delete pages on their webpage.

So i thought it would be great to create an sub sitemap which holds the 
pages for the webpage.
You mean you want to define single pages in a Cocoon sitemap?
Could you explain why this approach is reasonable in your
usecase?

Hello everyone,
we finally have a room for the GetTogether.
We will have a Meeting about cocoon and lenya in Madrid, Spain.
It will last 2 days: 21/22.06.04.
We have 15 places with computer in total.
6 places are already taken so 9 are still aviable.
Note:
We are trying to invite somebody from *Wyona* to attend the GetTogether.
We can offer him/her to pay the cost for the travel.
*If* somebody from wyona is willing to come, the price for the 
GetTogether will be *around* 20-30€ for 2 days workshop and 
presentation. This money will hopefully cover the expenses for our guest

So please hurry up and register now!
I would like to join you (added myself to the Wiki page).
So I'm afraid you have to speak English :)

causes exception

[Andreas Hartmann]

Hi Cocoon community,
what's wrong with this XSP snippet?

  foo
  list

It causes a ProcessingException in ServerPagesGenerator.setup().
-
It seems like the stylesheet terminated with a message
( in logicsheet-util.xsl)
javax.xml.transform.TransformerException: Stylesheet führte zu Beendigung
at org.apache.xalan.templates.ElemMessage.execute(ElemMessage.java:162)
How to find out this message?

Thanks in advance!

BTW, applying the input.xsl logicsheet by hand worked
fine:
this._xsp_module_helper.getAttribute(objectModel,

Hi Andreas,
is the namespace for input: at the xsp:page ?
xmlns:input="http://whatever";
This would have pointed me to the solution (duplicate
namespace declaration). But I already found it (see my
other reply).
Thanks a lot!

The logicsheet contained an additional declaration of the
input module namespace before the used declaration:
  xmlns:xsp-input="http://apache.org/cocoon/xsp/input/1.0";
  [...]
  xmlns:input="http://apache.org/cocoon/xsp/input/1.0";
The first one was matched by the "get-namespace-prefix" template
in logicsheet-util.xsl. Because no appropriate parameter tag
was found, the stylesheet terminated.
BTW, I consider this as a Cocoon bug, because using namespace
prefixes to resolve anything in XML is not useful. Isn't it
possible to rely just on namespace URIs in logicsheet-util.xsl?

Ups,
I thought that the declaration for a logic sheet must only match to the 
cocoon.xconf

could it be that xsp-input was in ver 2.04
and now only input is valid
If this is true, it is very strange ...
IMO there shouldn't be any restrictions/rules regarding the
namespace prefix, only the URI should matter.

TextSerializer and UTF-8

[Andreas Hartmann]

Hi Cocoon community,
when I use the text serializer with UTF-8 encoding, Internet Explorer
does not recognize the encoding and screws up the umlauts.
With the XML serializers from the serializers block, the problem
does not appear. Is there any workaround for the text serializer?
Setting the Content-Type header using the HttpHeaderAction does
not work, I guess it is overridden by the serializer:
   
 
   
Thanks in advance!

Hi,
I'm not certain whether it really works, but TextSerializer and 
XmlSerializer are very much similar. Ever tried to define a new 
TextSerializer with the encoding explicitly set to utf-8?

Yes, I'm using this configuration, but unfortunately it doesn't
change anything.
Thanks for your help!

OK, I'll try that.

Can I combine this with the cocoon:// protocol? My text file

Really ought to work. XMLSerializer and TextSerializer both extend the 
AbstractTextSerializer
Actually the XMLSerializer (I'm using the serializers block) extends
the EncodingSerializer, which extends Object and implements Serializer.
I guess I'd need a TextSerializer based on the EncodingSerializer.
and that one contains:
if (encoding != null) {
format.put(OutputKeys.ENCODING, encoding);
buffer.append(";encoding=").append(encoding);
}
But isn't this just used for the caching key?
I didn't find any code which attaches the encoding information
to the HTTP header.
I suspect that the trouble is caused by something else...
The browser perhaps? :-P
Yes, it is definitely the browser, but nevertheless I have to find
a solution ... :|
Thanks for your time!

Cron + HSQLDB: Unexpected token: in statement [SELECT 1]

[Andreas Hartmann]

Hi all,
I'm trying to run the cron block with the TX job store and the
built-in HSQL DB. My configurations:

  LenyaScheduler


  

jdbc:hsqldb:hsql://localhost:9002
sa

  

I added the Quartz tables to cocoondb.script. When I start Jetty, I can
connect to the DB with the org.hsqldb.util.DatabaseManager browse the tables.
But during the cron block startup, I get the following exception:
main WARN  lenya.scheduler - Could not prepare test statement, connection 
recycled on basis of time.
java.sql.SQLException: Unexpected token:  in statement [SELECT 1]
at org.hsqldb.jdbc.Util.throwError(Unknown Source)
at org.hsqldb.jdbc.jdbcPreparedStatement.(Unknown Source)
...

It looks like a test statement is created, but HSQL couldn't parse it and
threw an exception. I found the following message in a forum:
>>DriverManager.getConnection("jdbc:hsqldb:hsql://localhost")
>>  trying driver[className=org.hsqldb.jdbcDriver,[EMAIL PROTECTED]
>>getConnection returning

>The SQL is correct. Yet another SQL incompatibility in HSQL.
This seems to be a known issue with HSQL. Updating to the newest
version (1.8.0-RC9) didn't solve the problem.
Is there anything I can do about it?
Thanks a lot!
