REPOST: [C2.0] Fatal Error when trying to use SVG

[Adrian Geissel]

Hi,

Are there any pointers as to where I should be looking to fix this?
I'm using the Cocoon 2.0 release distribution, and get the error described
below.

Thanks,
Adrian

===


Hi,

I'm running Cocoon 2.0 (Final Release) on Tomcat 3.2 on Windows NT 4.0 SP5.

I get the message "Fatal Error: No usable fonts found." when accessing the
Cocoon SVG sample link (of the main sample page), and Tomcat dumps with
"Java Result: 1".

I have attached the cocoon.log from this session, but am unable to locate
any hints as to what happened.

Has anyone else experienced a similar problem? Or any thoughts?
Many thanks,
Adrian

Re: Re: Antwort: RE: Calling C2 from command line: problem with Oracle driver

[Adrian Geissel]

Hi,

Have you looked at the way that Cocoon generates it's own documentation from
a commandline invocation?

This may be what you are looking for in terms of generating off-line
content.

Hope this helps

Re: Look-and-feel approach with views

[Adrian Geissel]

I suggest that there is an easier approach to solve your look&feel issue.

Assuming that the L&F is supported by means of some transformation, then why
not use the following sitemap construct:














That way, look and feel is handled in a single location and there is no need
to extend the sitemap language.

Hope this helps,
Adrian

Hi Johannes,

Have a look at the  and  sitemap elements.

In essence, the aggregate allows you to collect the generated output of your

Re: XSP+XSL->TEX->PDF?

[Adrian Geissel]

Hi Victor,

I believe that you biggest hurdle is performing the second stage  - as you
need to transformation needs to take TEX input and deliver PDF output, which
is beyond the remit of the Cocoon framework (intermediates are XML).

Have you considered using xsl:fo during your content rendering, ie. instead
of using Tex-XSL, using FOP (formatting objects for PDF) which allows you to
generated to PDF directly.

Your pipeline would then look something like:



  
  
  



You will need to provide the 'xsp2fop.xsl' stylesheet, as this defines how
your XML output from 'my-doc.xsp' should be presented. The other components
are standard in the Cocoon distribution.

I hope that this helps some
Adrian

[C2] Extending the available components

[Adrian Geissel]

Hi,
 
Appologies in advance for a 'heavy' technical 
question, but I reckon that it may be of interest to 
cocoon-users.
 
My Cocoon-based application requires access to an 
ftp repository, both for upload and download support. I have an ftp-client 
implementation that allows me to perform this work. 
 
My question has two parts - firstly, is there 
an easy way to bind to configuration parameters (IP, user, password, etc) 
from cocoon.xconf? I figure that I need to implement some  Avalon framework 
interfaces, but then the question is which ones, and how do I register the 
component?
 
The second is related, but concerns connection 
pooling - in a manner similar to SQL connection pooling. Can the connection 
pools be associated with external components, or just Cocoon internal ones? 
Also, can someone indicate how I would go about registering / configuring such a 
pool?
 
Many thanks,
Adrian
 

[C2.0rc1] Problems with IE5.00 - throws an Exception during endDocument processing after sitemap redirect

[Adrian Geissel]

Hi,
 
I've logged this as a bug for C2, but I also wanted 
to see if anyone else is having this problem.
 
Scenario:
 
my sitemap performs some processing (database 
update) in an action, and on success, redirects to another page before returning 
using the supplied redirector object. The URI that it points to is also served 
by the sitemap, and also consists of aggregated content that is transformed - 
all things legal and cool.
 
The problem is that using IE 5.00 (WinNT 4.0 SP5), 
the redirected URI is not completed, and eventually the connection times-out - 
not very good. To make matters worse, the problem does not exist if I access the 
redirected page directly from the browser, or perform my database update action 
from another machine running IE 5.5 (Win2k), the problem does not 
exist.
 
Has anyone else experienced this?
The full bug report is at http://nagoya.apache.org/bugzilla/show_bug.cgi?id=4438 (applogies 
for the long report, but it has taken a while to isolate the 
problem)
 
Many thanks,
Adrian
 
(please don't gripe about IE - this is a 
real problem - I'm just looking for other instances, and possible solutions. 
thanks /A)

[C2.0rc1] Exception when redirecting during pipeline processing

[Adrian Geissel]

Hi,
 
My question relates to breaking out of a 
pipeline after the generate stage has completed. Specifically, the generate 
stage performs some processing as XSP, and based on the success/failure of this 
processing, the pipeline is allowed to continue, or 'breaks-out' using a 
redirect. When I configure my sitemap to do this, an exception is thrown, and 
looking at the stacktrace, it appears that this is not legal. 
 
Has someone configured something similar, or 
alternatively, what is the recommended approach? In reference to suggestions, I 
would really like to be able to perform my processing (database updating) using 
XSP, as this needs to be flexible in a multi-customer environment and currently 
uses logicsheets to achieve this. Also, if the processing fails, the XSP returns 
valid XML to re-populate the original form.
 
Many thanks,
Adrian

[C2.0rc1]: Question relating to request object lifetime during aggregation

[Adrian Geissel]

Hi,
 
I have a scenario where I am aggregating content 
from three sources, one of which is an XSP retrieved using internal cocoon 
protocol. This XSP calls request.setParameter() to indicate a 
status.
 
The aggregation event is followed by an action that 
tests this status, but it always is set to null.
 
Question: am I correct in assuming that the same 
request instance is used across all internal cocoon protocol 
requests?
Question: if this is the case, is there a reason 
which my attribute should be lost?
 
Many thanks,
Adrian

[C2] Help: Unexpected bad XSP/Logicsheet behavior

[Adrian Geissel]

Hi,
 
My logicsheet provides XSP support templates, 
for controlling the structure of the generated XML. A typical template 
generates an XML fragment, including the local 'root' (top-level) element, 
attributes, content and child elements.
 
The strange behavior is that my 'root' element is 
not being processed (in the example below,  is never created), 
but all subsequent attributes, content and child elements are processed as 
expected.
 
I've looked at the XSP generated java file, 
which does not issue any SAX events relating to the creation of the first 
element, but everything else is there as expected.
 
This logicsheet worked 'perfectly' in Cocoon 1.8.2, 
and I have made the appropriate namespace changes to C2 enable it.
 
Does anyone know what's happening 
here?
Thanks,
Adrian

Re: [C2.0rc1] SLIGHTLY OFF TOPIC: Has anyone used Xalan extensions in Cocoon?

[Adrian Geissel]

Oops - it's just a little too early on a Friday morning!

I 've spotted the error - the XPath expression was technically correct, but
the test data was not correctly Generated - thus it did not exist for the
transformer.

However, I hope that this approach may thus be of benefit to someone else,
albeit Xalan specific.

Adrian

[C2.0rc1] SLIGHTLY OFF TOPIC: Has anyone used Xalan extensions in Cocoon?

[Adrian Geissel]

Hi,

I appologise in advance for posting to this mailing list, but I also think
that the answer maybe of interest to the Cocoon community.

What I am trying to do is to build a generic form within C2 that is defined
in an XSP which is aggregated with another path that will contain the data
which is to be plugged into the form, thereby allowing for improved form
(UI) reuse across scenarios. In trying to do this, I need the ability to
perform run-time XPath evaluation, rather than at programming time.

I have found a Xalan extension function (luckily before I wanted to write my
own :) that appears to do the trick. Its called "xalan:evaluate()" and takes
an XPath expression as a parameter, which in turn contains an XPath
expression, which is then evaluated and returned.

I've read the docs, but can't get it to work. The docs say to use the
namespace   xmlns:xalan="http://xml.apache.org/xalan";. I'm calling the
extension function in my xml2html transformation stylesheet as follows:

http://www.w3.org/1999/XSL/Transform";
  xmlns:xalan="http://xml.apache.org/xalan";
  xmlns:zdam="zenark.com/zdam"
  exclude-result-prefixes="xalan"
>



...

  


  

...





The problem is that evaluate() returns '', rather than the expected real
value. The returned XPath expression (in @bind-to) is correct.

Any thoughts or experiences?
Thanks in advance,
Adrian

Re: nested stylesheets

[Adrian Geissel]

Hi,

The issue with logicsheet XSLs is that they should translate what they
understand and pass through what they don't. This in effect is how the
embedded tags are resolved, when all logic sheets are run against the XSP
file. Any tags that are left over are output in the resulting Document
(logically).

To make this happen, there are two minimum requirements for your logicsheet.

Firstly, provide a template that processes the  element, which in
turn creates an  element as a root context for the follow-on
logicsheets. For example:

  

  
  

  


and Secondly, to ensure that all unprocessed elements are copied, include
the following template in your logicsheet:

  
  

  

  


Hope this helps,
Adrian

[C2.0b2] - ComponentManager

[Adrian Geissel]

Hi,

We looking at migrating our application from C1.8.2 over to C2.

In C1.x, we used Turbine for connection pooling, and we need to move over to
the Avalon CoponentManager framework.

There was one real advantage in using Turbine, where there is a
singleton-access to the connection-pool, thereby allowing it to be easily
integrated with external code. Basically, we have a tried-and-tested
database access library that takes utilises an internal ConnectionFactory
that calls into Turbine for its connections.

I have not found a similar factory method for accessing either the Cocoon
object, its ComponentManager, or any managed components. Have I missed
something, or is there a preferred approach? A non-singleton access to the
connection pool will require a potentially reasonable coding change.

Also, having a little difficulty in configuring a pooled connection to
PostgreSQL - I've followed the instructions in the 'datasources' document,
but the ComponentManager complains that the named component cannot be found.
I've included the relevant bits from both cocoon.xconf, the calling code
(from within an Action) and log-file extract.

Any and all help will be greatly appreciated,
Many thanks
Adrian

[C1] Update / enhancement for the sendmail.xsl logicsheet

Hi all,

I appologise in advance for submitting this update / enhancement to
cocoon-users - but perhaps a member of the cocoon-dev list can do the
needful :)

The replacement template from sendmail.xsl included below allows sending of
rich-text mail content. HTML content can be included by qualifying the

I believe that this change should also work with the C2 logicsheet, but I

Re: Passing document, request & resonse to other methods

[Adrian Geissel]

Hi Dave,

why not just let the XSP processor create the DOM nodes - and use the
 and  tags to embed functionality in the output.
If you need to control the addition of elements to the DOM in your own code,
then use the ,  and  tags -
they'll be properly resolved, less coding and fewer errors as a result (and
C2 SAX-based compatibility for free!).

Getting Cocoon 1.8.2 working with

[Adrian Geissel]

Hi,

I want to use a later build of Xalan (xalan-j_2_0_1.zip) with Cocoon 1.8.2

I've tried dropping in the appropriate JARs from Xalan (xalan.jar,
xalanj1compat.jar) - replacing the Xalan JAR that came with the
distribution, but I get the following stack-trace:

java.lang.RuntimeException: Exception when creating "
org.apache.cocoon.transformer.XalanTransformer" :

Re: using XSP : element ???

[Adrian Geissel]

Hi,
I use the same construct as below throughout my app.
The error message returned by the SAX parser may indicate that the XML prior
to the fragment below has a problem - I have seen this message when I have
failed to close an earlier tag - or have mistakenly included a closing tag
without a corresponding open.

Another suggestion may be to remove the whitespace between the
 and  tags, although this tends to just distort
final output.

Hope this helps,
Adrian

Re: session-invalidator and back-button?

[Adrian Geissel]

Hi,

I should have mentioned in my last reply that it is still the responsibility
of your application to ensure that sensitive content is protected - using
session parameters, or whatever. The solution I presented is for the
client-side issue.

Cheers
Adrian

Re: session-invalidator and back-button?

[Adrian Geissel]

The solution presented is not a Cocoon specific solution, but rather
addressess the issue of the client-side browser keeping a history.
In a past life, we coded an application to do this using JavaScript that the
browser used to spawn the protected window. All pages accessed and presented
within the window are basically unchanged, therefore only requiring
JavaScript on the Login and Logout pages.

This is not an elegant solution, but it can work once you cater for the
major browsers (script variances).
Cheers
Adrian

Re: session-invalidator and back-button?

[Adrian Geissel]

Hi Michael,

I believe that the only way to solve such an issue is to 'run' the protected
portion of your website in a spawned browser window, and then when the user
log's out, to close that window. This will ensure that the Back history,
which is local to a browser window, cannot be access with permission.

Hope that this helps,
Adrian

Re: Web-inf/lib

[Adrian Geissel]

Hi,

We have this working with Tomcat 3.2 and Cocoon 1.8.2.

What we found was that when the WAR is first installed, it is expanded as
expected. However, before the JARs can be loaded by the Cocoon app, Tomcat
needs to be restarted (basically the restart needs to happen twice - once to
expand the WAR and once to load the JARs).

I hope that this helps,
Adrian

[C1] Generating a HTML frameset using XML/XSLT

[Adrian Geissel]

Hi,
 
We are just trying to put a dynamic frameset as the 
primary entry-point for our application, and using all that we've learnt so far, 
we created an XSP file with an associated stylesheet (included at the end of 
this mail). We get an unusual SAX exception when accessing the 
frameset:
 
org.apache.cocoon.processor.ProcessorException: 
Could not associate stylesheet to document:  error reading 
C:\tomcat\webapps\zdam\index2html.xsl: org.xml.sax.SAXParseException: Attribute 
name "FRAME" must be followed by the '=' character.
 
Has someone come across this before or successfully 
implemented framesets? 
All help is gladly accepted.
Thanks,Adrian
 
Cocoon 1.8.2
Tomcat 2.3
Windows NT
 
=
XSP simply generates the following:
 

 
=
  
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  
xmlns:xsp="http://www.apache.org/1999/XSP/Core"  
xmlns:mystuff="mystuff.com" >
 
 
 
      
  
    
 
        
          
      

 

 
 

Fw: Tomcat problem

[Adrian Geissel]

Appologies, my previous message should have 
read:
 

Hi,
 
We are using Tomcat 3.2.1 and Cocoon 1.8.2 and are 
writing an XSP logic sheet - the functionality works well except for one 
aspect. We are deploying our application using a WAR file that is dropped 
into the Tomcat webapps directory. According to the documentation, Tomcat 
expands the WAR (it does) and should automatically add the /WEB-INF/lib and 
/WEB-INF/classes folders to the CLASSPATH for that webapp.
 
Our problem is that Cocoon is not picking up the 
JAR file containing the XSP XSL files (located in the 
.../webapps//WEB-INF/lib directory).
 
I know that this sounds like a Tomcat issue, but 
has anyone managed to deploy a Cocoon app from a single WAR - without requiring 
user specified CLASSPATH entries, etc. We're aiming for a minimal configuration 
installation and this would be really nice. An intersting point is that Cocoon 
can locate our custom Java classes from a different JAR in the same directory, 
but can't find the XSL files.
 
Any thoughts are greatly appreciated,
Adrian

Put the following into your style-sheet (the last in the chain)


type="text/plain"

...



You will need a dummy root tag, as XSLT expects to write out XML - but when
displayed in the browser, it should appear as plain ASCII text.

Hope this helps,

Extending the standard Cocoon XSP logicsheets, namely ESQL

[Adrian Geissel]

Hi,
 
I'm using Cocoon 1.8.2 and it's great - 
dynamic content generation in an efficient and controlled manner - a real 
winner!
 
As with all technologies, there comes a point when 
you want it to do more - and my current aspiration is to improve the way that 
SQL is handled, specifically the ESQL.xsl logicsheet. What I am trrying to do is 
to structure the query statement that is passed as part of the esql:query tag, 
as follows:
 
...

 
      
   
        
   
  
 


...

...
 
I have a logic sheet that handles the zsql 
namespace and it works really well on its own - it even allows other logicsheets 
(taglibs) to be called from it using a 'get-nested-content' template (such as 
the  in the sample). However, the above code 
structure results in Cocoon generating a DOM sub-tree under the 
 tag, rather than calling the appropriate templates to format 
the query string.
 
I have tried a number of approaches, including 
adding the zsql namespace to the esql  tag, and I believe that 
my logicsheet is locatable, as I created a jar, included it in the CLASSPATH and 
also updated the cocoon.properties to point to it.
 
Is there something that I have missed, or am I 
trying the impossible? Any help is gladly appreciated.
 
On a slightly different note, if anyone is curious 
about the zsql stuff, please drop me a line as I am putting together an open 
project to structure and deploy sql script from single source to multiple 
destination (vendors) as well as documentation - a really nice showcase for 
Cocoon, if nothing else.
 
Many thanks,
Adrian

Mixing XSL and XSP in a single stylesheet

[Adrian Geissel]

Hi,
 
I'm trying to write a data abstraction layer to 
retrieve records from an SQL database (using ESQL) and then to format these into 
an XML fragment (using XSLT) for onward transformation.
 
It appears that the xsl: namespace elements are not 
being executed - can I do this in a single step, or do I need to tease it apart 
into two transformation steps? I've included the important code fragment below, 
with comments following the xsl statements that do not work.
 
Any help will be greatly appreciated
Cheers
Adrian
