Of course. I thought it might take it from the a parent XSP element but it
doesn't.

Yep, you're right of course, copy/paste sloppiness.

[aside: is  a real thing?]

I see you're point. But I'm willing to let that case go for efficiency as
long as we protect the beginner from naiive mistakes like
name="cinclude:include". Just testing for ':' within @name would help
prevent highlight their error instead of doing nothing at all.

It turns out that the CIncludeTransformer (correctly) skips the element
completely (because the namespace URI isn't applied to the element) but when
you examine the XML, it's not at all apparent, especially if you've added
the cinclude namespace at the top. Instead, the cinclude:include element
continues to appear in the output, no matter what you do to the sitemap,
mistakenly thinking that the transformer isn't being executed.

Re: pb with http request

[Joerg Heinicke]

This has nothing to do with the example, it's a common error message, 
when having the XML declaration not as the absolutely first thing in the 
XML file. There must not be any whitespaces or other characters in front 
of the XML declaration and it has to be in the form as at 
http://www.w3.org/TR/REC-xml#sec-prolog-dtd. Watch for case-sensitivity 
too. Have a look in all the related files to fix the bug.

This one seems to be ok, but I can't see whether there are any 
whitespaces in the file of course.

RE: action not working

[sylviat]

Hi Vadim -

Thanks for the suggestion - my code now works
perfectly.  I actually knew that an action not
returning a map object will cause the rest of the
pipeline, inside the , to be skipped.  

I didn't think this was my problem because in sample
code 'employee.xsp' the action is not always executed,
yet the pipeline always executes -- at least that how
it seems. Maybe I'm missing something.

Anyway, thanks again.  It's great that you're out
there, answering questions and giving help.  It's
really appreciated.

Sylvia

It will not be efficient to do this, because this check must be made at
run time, and every time. I guess you have not considered that this is
possible:

How to use LinkSerializer

[Torsten Knodt]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hello,
currently I have the problem, that LinkSerializer isn't working on all 
HTML-Tags, that I'm using in my HTML output. I've thought about adding them 
to the source, but I think it's better to prepend a xsl to the LinkSerializer 
to transform these tags to xlinks. When I'm not wrong this is also done in 
the java source for the existing tags. But I could'n figure out the right 
format to output to the LinkSerializer. Any hints? Can anyone give me 
examples how the tags should look to be used by LinkSerializer?

With kind regards

pb with http request

Hy,  
 
I just was trying to run the example 
wrotten by Steve Punk in "Getting started with Cocoon 2" http://www.xml.com/lpt/a/2002/07/10/cocoon2.html
 
More precisely, the last example that 
calculates a factorial from a numeric value submitted via HTTP 
POST.
 
Here's the sitemap:

and here's the file mystylesheet.xsl 
that I've copied in integrality from the original source:
 





xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:http="http://xml.apache.org/cocoon/requestgenerator/2.0">

When I run this by pointing my browser to http://localhost/mypage?input=5
I receive the following error 
message:

I don't understand why this occurs. Can you help me

Hi,

In my action I extract the name-value pair from my URI and send it to my

It sounds like you simply renamed the .war to .ear. Is that what you

Error handling in xsp:element...

[Per Kreipke]

If I do the following in an XSP, the CInclude transformer doesn't recognize
the cinclude:include element because it has no namespace associated with it.


  strURL



I had to change it to be:

http://apache.org/cocoon/include/1.0";>
  strURL



In the second example, the condition where I forget to include both @prefix
and @uri, I get an error. But in the first example, there's no error even
though cinclude:include is an invalid XML element name without a namespace.

xsp.xsl would need an extra check.

Have a look at the getParameterValues() method (or

containing all values.

Chris,
  I have attached the output (including stack trace).

  I haven't got any esql to work. I even tried not using the datasource 
(even though it works in the actions i've created) and include the esql 
tags for drive, url, username etc. and the reult is the same: the

I'm certain that others do use oracle sps the way described. Actually,
the esql sp support started that way...

RE: jboss 3 + cocoon 2.0.3

[Terry Anderson]

Gerhard,

Not sure if you got an answer, but I just got cocoon 2.0.3 + jboss 3.0.0
+ tomcat 4.0.3 running.

I built the standard cocoon webapp (.war) into a .ear file and deployed
from that.  When I tried to deploy the .war file, I got the same error
you mention below.  The .ear file works, however.

Good luck,

Terry Anderson

Hi!

I deployed my own war file based on cocoon 2.0.3 in jboss 3.0 (with

The deployment works without any errors but when I try to access the

I got your point.

If there is interest in adding this feature, and no developer will
object, it should not be too complex to implement this feature.

multiple checkboxes and request parameters passed to an xsl

[Barbara Post]

Hello, how can my stylesheet get all the http request parameters since the
http request sends a variable number of parameters named "checkedbox_i" for
example, "i" being an unique identifier ? checkboxes are in variable number
on the submit page, depending on a former choice.

on the submit page the user chose the checkboxes to check then submitted.

Best idea would be a javascript to create an unique parameter "checkboxes"
with i1_i2_i3... for value, then xsl could do substrings ?

Thanks for any idea. the unknown data is the number of checkboxes, and the
number of them to be checked... then the checked ones are used to match
against an xml file and construct final html output (another form).
Hoping that I am clear enough.

If action set did not returned result (i.e., no action were executed),

RE: How to use map:redirect-to combined with serverpages

[Christian Hoofe]

This is my solution for a serverpage redirect combined with an action:

1. Sitemaps needs ServerPagesAction

  

   
   

2. Site matcher

   

  
 
  



   ...

   

3. Call of the matcher

   

   ...



The "next" parameter tells the sitemap the next page to call. In this case the itself.

4. The xsp page with the database logic 'db/art_grp_chg.xsp'



http://apache.org/xsp";
  xmlns:esql="http://apache.org/cocoon/SQL/v2";
  xmlns:xsp-request="http://apache.org/xsp/request/2.0";
  xmlns:action="http://apache.org/cocoon/action/1.0";
>

  
   A Database Driven XSP Page

   
 

   String process = null;
   String id_str = null;
   intid = -1;
   String ord_str = null;
   intordnr = -1;
   String name = null;

   process  = ;
   id_str   = ;
   id   = Integer.parseInt(id_str); 
   ord_str   = ;
   ordnr = Integer.parseInt(ord_str);

Re: XSP implents Interface ?

[Dr. Hans M. Rupp]

We have an architecture where a command puts objects into the request or
session and the XSP fetches those Objects. Since both the command and the
XSP need to know the attribute name of a particular object in the
request, I thought it might be nice to have an interface where the
attribute names are declared. Then both the XSP and the command could
implement this interface.

Re: esql - oracle stored procedure returns resultset

[Frank Taffelt]

> So you need to return a cursor as first parameter and use
> @resultset-from-object="1"

yes but the to code to achive this is oracle dependent:
IMHO code to achive this should look like:

1 CallableStatement cstmt = conn.prepareCall(query);
 2 cstmt.registerOutParameter(1,OracleTypes.CURSOR);
3 cstmt.execute();
4 ResultSet rset = (ResultSet)cstmt.getObject(1);

the problem is line 2 which uses OracleType.CURSOR and no standard jdbc type
. i think this
code is not suitable for esql-logicsheet or ist it ?

without registering the cursor the oracle driver assumes a different
signature for the procedure and therefore cannot find it (this explains the
error from my last try).

so i think it's not yet the time for a summary  ...

P.S. i'm not that jdbc-oracle-expert maybe somebody has a solution for this

RE: action not working

[sylviat]

Vadim, thanks a lot for your reply.  I now understand
the '../1' syntax.  Unfortunately though it seems that
this is not the problem.

The matchers in my pipeline are hard coded, ie:


  



   


I am getting "The requested URI /cocoon/demo/abc" was
not found." message (I am running from the subsitemap
"demo").  But when I comment out  and
 it runs fine.  I also tried this from the
main sitemap with the same bad results.

Originally, I cloned the /forms/employee pipeline (it
uses the db actions ), changed the 'src' attributes
for generate and transform files, and put those files
in /docs/samples/forms - just like the /forms/employee
pipeline.  It works fine from there with the action
and all, but not from anywhere else.  

Any ideas?  Again, thanks so much for your help and
effort.  
Sylvia

IIRC, remote server has to return "Last-Modified" header (see URLSource.
getInfos()). Otherwise, Cocoon will assume that content is not cacheable
(in accordance with http spec).

I am confused by your example, the way it reads to me the default xsl will always run,

Re: using request selector to choose xsl

[Jo Bourne]

Hey Barbara,

thanks for your suggestion, unfortunately it won't work for us as sending a style all 
the time would require a massive rewrite of our system which generates all the urls 
automatically and it is really only occassional special cases we need to catch with a 
specified style

thanks though!

AW: caching strategy

[Sternath Elmar]

Hi Vadim,

thanks for your support. Caching works now for JSPs and also for CIncludeTransformer 
as long as I get my XML input from static xml files. Unfortunately, I have to get my 
XML input via HTTP requests from a remote server. In this case, these requests are 
always executed, caching does not work. Do you have any idea how to solve this 
problem??

Thanks,
Elmar

Components decide for themselves whether whatever it does changed or
not. Browse through user docs, for example:
http://xml.apache.org/cocoon/userdocs/generators/file-generator.html:
"Cacheable: yes - uses the last modification date of the xml document
for validation".

For XSPs, see cacheable.xsp sample.

And with ServerPagesAction it's possible to reuse existing logicsheets.

It is reasonable, and doable. But, OTOH, it's easier to do such sings
with "side-effect transformer", like SourceWritingTransformer, on top of
which  application was built, or XMLDBTransformer (which
can write to XML:DB), etc.

Also, see recent thread on cocoon-dev with links to all previous
discussions, including "cocoon symmetry":
http://marc.theaimsgroup.com/?t=10276748526&r=1&w=2

Final decision is not made yet.

Ah, this is where @resultset-from-object="1" comes back into play:
Have that parameter registered as object and automagically the first
(just noticed a bug: currently only the first) parameter is turned
into the current ResultSet! :-)

So you need to return a cursor as first parameter and use
@resultset-from-object="1"

Well, haven't thought of that (yet). My other idea was about the yet to 
be  flow script system. Stefano gave an example save2disk() flow that 
would be able to save a resource defined by sitemap to disk (so what?). 
This was in the vision department of his RT, however. So I don't expect 
this soon to be possible.

The other part really is a SOAP response. Which isn't possible with C2 
either. Or at least not as easy as with Axis and friends.

Does your code equal (more or less) the one produced by esql?

ok second try with:

But for the debug purposes, can you try running cocoon with only one
xslt processor, saxon, to see what result will you get?


Also, try adding to TOMCAT_OPTIONS:

Okay so the issue is that you have *two* outputs of sort.  One is to 
email, one is to the browser.  The Excel is to email and probably HTML 
to the browser.

In my mind this doesn't justify *breaking* the logical model of the 
sitemap.  It seems you need an Action that makes a seperate internal 
request of sorts and emails the output.  So the action would make a 
request to a different pipeline and email that, where the user response 
would be in HTML.

Does that not sound reasonable?  Any thoughts from you Vadim?

Filtering HTML pages

[Matthew Langham]

Hi gang,

we are working on a project where one of the main goals is to provide a
filter for external web pages. The idea is that the client accesses the
"filter" running on a server and then receives HTML pages that have been
filtered according to certain rules.

One way of doing this is obviously running the pages through the html
generator in the cocoon pipeline and using stylesheets to alter the XHTML as
needed. The advantage being the flexibility and the use of caching.

Has anyone done this already or can perhaps suggest an alternative way of
doing this?

RE: Better way to aggregate?

If I understand correctly, the aggregation will read the data from each of
the subordinate pipelines WITHOUT the serialization step, so these 2 would
be equivalent.

Better way to aggregate?

[Alex Romayev]

I've been looking into the aggregation techniques and
there seems to be two ways people go about doing it. 
I'm trying to understand the pros/cons of the two
approaches.

Approach 1: Aggregate HTML
Each map:part calls a pipeline, which generates,
transforms and serializes to HTML, e.g.,




Approach 2: Aggregate XML
Each map:part calls a pipeline, which generates and
serializes to XML, e.g.,



Any ideas?

Try without the @resultset-from-object attribute, it serves a
different purpose. Try 
  { sp_get_stocks(20) }

I believe, oracle doesn't need @needs-query.

Multiple map:resource calls

[Lorenzo De Sio]

Hi all,

it seems to me like it is not possible to perform multiple  calls in a single matcher.

Fragments from my sitemap:

[...]

 













 

[...]



[...]







[...]

Both resources work, if used only one at a time. But, as soon as I try to
use both of them in a single matcher, I get the following exception:

duplicate definition of variable methodName in method matchN10092
[...] duplicate definition of variable argTypes in method matchN10092 [...]
duplicate definition of variable argValues in method matchN10092 [...]

which is obvious, if we look at the generated sitemap.java:

  map = new HashMap(1);
  
  String methodName = "resource_" + substitute(listOfMaps,
"crea_form_dati");
  listOfMaps.add(map);
  this.dumpParameters(listOfMaps);
  Class[] argTypes = new Class[] {StreamPipeline.class,
EventPipeline.class, List.class, Environment.class, String.class,
Boolean.TYPE};
  Object[] argValues = new Object[] {pipeline, eventPipeline,
listOfMaps, environment, cocoon_view, new Boolean(internalRequest)};
  if (true) return invokeMethod(methodName, argTypes, argValues);
  
   map = new HashMap(1);
  
  String methodName = "resource_" + substitute(listOfMaps,
"aspetto_finale");
  listOfMaps.add(map);
  this.dumpParameters(listOfMaps);
  Class[] argTypes = new Class[] {StreamPipeline.class,
EventPipeline.class, List.class, Environment.class, String.class,
Boolean.TYPE};
  Object[] argValues = new Object[] {pipeline, eventPipeline,
listOfMaps, environment, cocoon_view, new Boolean(internalRequest)};
  if (true) return invokeMethod(methodName, argTypes, argValues);


Any hints? Am I doing wrong in trying to call two resources in a matcher?
Are there any correct alternatives?

Thanks in advance to anyone,

L.

So, I like to use both:
I defined a component
"

." that uses Saxon in cocoon.xconf
and i defined another transformer (xslt-saxon) that calls this component
with:
"org.apache.cocoon.components.xslt.XSLTProcessor/Saxon"

In WEB-INF/lib there is saxon652.jar
Here are the coplete extracts of my cocoon.xconf and sitemap.xmap:

false
false

Re: i18n key generation with xalan

[Joerg Heinicke]

I assume you are trying to use the i18n transformer with Xalan command

is it possible in Cocoon to define and set some kind of global variable which I can
