java problem in XSP

[sreenivas reddy]

Hi


  Process p=Runtime.getRuntime().exec(arg);
//in linux
BufferedReader br =new BufferedReader(new
InputStreamReader(p.getInputStream()));
  while ((line = br.readLine()) != null){ 
System.out.println("line:"+sLine); }



 
I observe that for  
1) arg="cp --help" it is returning something  but for
  arg="cp" there is nothing output
is there any otherway to print?

Well, by clicking on a href="/miracle/app/cook/info.gif" in my
xhtml-source-code my browser connects to the following address:
   http://server:/miracle/app/cook/info.gif
But if I want to serve static content with apache, it should be
   http://server:80/miracle/app/cook/info.gif
Do I have to modify my generated xhtml-code to achieve this or

When done properly your links will be the same as they are.  All 
incoming
requests go to apache at port 80. Apache forwards the stuff it isn't
handling to the servlet container (in this case at ).  This is an
extremely common configuration (not just for Cocoon). You should search
the Apache http server site for more information.

Hi Ralph,
thanx for your answer - in my test some days ago using TinyWeb
I was explicitly putting "http://server:80/"; as prefix to the
href- resp. src-attribute values.
Anyway - I'm not quite sure if serving static content using
Apache would be an advantage in my situation. My application
reads sentences of a symbolic language from a XML-source and
converts the data to XHTML. The resulting page in the browser
contains many images, but there're many duplicates (because
most symbols are used two or more times).
Might cocoon's caching be an advantage under this circum-
stances?
thanx,
Gerald

encodeUrl Transformer and unicode

[Doug Chestnut]

Hi All,
I am working on a project in cocoon where I need to encode url strings (that
contain diacritics) in an xml document like described on this page:
http://www.w3.org/International/O-URL-code.html

Is there any reason why the encodeURL Transformer doesn't do this?
( http://marc.theaimsgroup.com/?l=xml-cocoon-users&m=107638965522631&w=2 )

Is there an easy way to encode unicode (w/ no ascii equivilent) characters
in a sitemap pipeline?

I guess if this is not available I could just extend the encodeURL
Transformer to use this:
http://www.w3.org/International/URLUTF8Encoder.java

Thanks for the help,

--Doug

Probably not.  If you are accessing the images via urls in your page then
serving them from apache will almost certainly be faster.  Caching in
Cocoon really helps in cutting down on building the dynamic content over
and over again, but it just can't serve static content as fast as apache.

[Repost] "no control flows defined", but there are!?

[Lars Huttar]

Dear Cocoon list,

Please excuse this repost, but I'm fairly stuck on this problem,
and can't make progress on starting to use CForms until I solve it.
I'm running Cocoon 2.1.5.1 under Jetty (even though it says Tomcat
below... it says that because my application folder, "gem", is
shared between two different versions of Cocoon).
I've also tried this under Cocoon 2.1.5 and get the same error.


I'm having some trouble setting up a simple CForms example. I'm
following the instructions at
http://cocoon.apache.org/2.1/userdocs/forms/sample.html
but modifying things cosmetically for my own example.

My problem is, when I try to access anything via the sitemap
that governs my example, the sitemap fails to load, with the
following error:

org.apache.cocoon.ProcessingException:
Failed to load sitemap from file:/c:/Program Files/Apache Group/Tomcat
4.1/webapps/cocoon/mount/gem/test/sitemap.xmap:
org.apache.avalon.framework.configuration.ConfigurationException:
This sitemap contains no control flows defined, cannot call at
file:/c:/Program%20Files/Apache%20Group/Tomcat%204.1/webapps/cocoon/mount/gem/test/sitemap.xmap:28:
54.
Define a control flow using , with embedded  elements.

It says the sitemap contains no control flows defined, yet I have
one defined just like it's specified in the instructions:

 
  
 
(under )

My flow/update.js file looks like this:

 cocoon.load("resource://org/apache/cocoon/forms/flow/javascript/Form.js");

 function update_Linguistic_Subgroup() {
 var form = new Form("forms/update-Linguistic_Subgroup.xml");

 form.showForm("update-display-pipeline");

 var model = form.getModel();
 var bizdata = { "LS_name" : model.name }
 cocoon.sendPage("update-success-pipeline", bizdata);
 }

Could the error above be caused by this update.js file containing
some sort of error and therefore failing to load?
E.g. if Form.js (first line) is not found?
However, sample files like
  samples/blocks/forms/flow/registration.js
load the same Form.js, and they have no such problems.

As I mentioned in a separate email, the files involved can be found at
 http://www.huttar.net/lars-kathy/tmp/sitemap.xmap
 .../index.html
 .../flow/update.js
 .../forms/update_success.jx
 .../forms/update-Linguistic_Subgroup.xml
 .../forms/update-Linguistic_Subgroup-template.xml

Thanks for any hints,
Lars

You have an apache web server at port 80. The static content is there and
apache serves that up.  Configure apache to proxy the requests for
non-static content to tomcat/jetty for cocoon to process.

I think there are advantages in using Hibernate to implement data 
persistence over a relational database whether you are using Cocoon or

not. Cocoon's concern is presentation and flow control. Hibernate's 
concern is persistence. The two concerns should not overlap, so that 
you could use a different presentation layer on top of Hibernate or a 
different persistence mechanism beneath Cocoon easily.

We happen to be using Cocoon and Hibernate simply because we believe 
them to be the best tools in their respective fields of application.

Articles, not that I know of, but you can find a complete sample here:

. And if you'd like to 
attend either OSCOM4 [1] or GT2004 [2], I'll be presenting a talk on 
Cocoon and Spring which will also cover Hibernate.

I don't think I can use this solution, since I need to know the continuation

the continuation in a deliveryUrl").

Re: Advantage using Hibernate with Cocoon

[Derek Hohls]

Johannes

I think you hit the nail on the head when you raised the whole
"elephant" thing.  I used the same terminology in a previous
thread. ;-)
http://marc.theaimsgroup.com/?l=xml-cocoon-users&m=108799013931354&w=2

A number of folks are pushing OJB... obviously each person
has there own choices, but I would like to see Hibernate 
offered as a serious alternative and one which dovetails well
with Cocoon's approach to life

For myself, being able to use Hibernate in an upcoming project
will be a *significant* advantage - I 'm prepared to bite the
bullet as far as learning  Hibernate's special requirements, as I
have looked through the docs and they seem pretty well written
and comprehensive (esp. c/w Cocoon's scattered docs.)

But, and this is a big BUT, there is very little guidance or samples
on getting Hibernate to work with Cocoon, apart from some very
limited and also outdated ones on the wiki [still, thanks are due
to Hugo who at least went to the effort of publishing something]

I have begged endlessly in previous threads (probably to the
point of really annoying people) about getting together some 
decent (aka "real world") samples and a user guide for doing
this... dare  I ask  - perhaps you are the person to do it??? I 
can offer time to read and test and comment if that will help -
there are others on the list who also have expressed a need 
before - maybe they will step forward as well!

Thanks
Derek

>>> [EMAIL PROTECTED] 2004/09/09 04:18:39 PM >>>
Hi Pat,

I have am now finishing my first project I used Hibernate and Cocoon 
together in,
so maybe you are interested in some thoughts from a beginner's point of

view.

The issue Hibernate addresses is how to get objects to and from the 
database. When
I started to use cocoon, I was impressed by the possibility to separate

design and
logic, using the sitemap and jxt/xslt for presentation and JavaScript 
flow control for
the control layer.

The most natural way to pass data to JX Templates seemed creating 
objects in JavaScript.
So I ended up writing objects - e.g. for articles sold in a web store -

using JavaScript's
weird constructor syntax. The constructors used SQL statements to fetch

the object's
data from a DB. Furthermore I had to define methods "update()" and 
"save()" for each
object to get the data back to the DB. These methods constructed SQL 
statements
containing the respective values.

That was more a PHP-like approach, where you are used to getting and 
storing data using
self-constructed SQL statements.

Now the principal advantage of Hibernate is that it creates a new layer

where all the
persistency stuff is handled. From my point of view, this has the 
following advantages:

- You can use "real" Java to write your business objects, there's no 
more need to use the
awful JavaScript syntax and it has all the obvious benefits like 
supporting interfaces,
inheritance, etc. (Well that's possible without Hibernate too, but 
Hibernate *forces* you
to do this.)

- The flow layer is reduced to what it is supposed to do, controlling 
application flow.
Complicated operations that are to be performed on the business objects

can be implemented
as Java methods. If you are familiar with Javascript, you will probably

agree that it is not
all too well suited for writing large and complex programs, due to the

lack of proper code
structuring facilities. Therefore I think, the thinner the control 
layer, the better.

- It's easier to change the underlying database. When writing native
SQL 
statements, one
often tends to use propietary DB features like, for example, MySQL 
fulltext search (since
it's just so much easier to use than java search engines :-) However, 
this cannot be ported to
Oracle or Informix, for example.

The main drawbacks I see are the following:

- Yet another Elephant you have to eat: The whole concept of
persistency 
is by no means
easy to understand. There's also a lot of hibernate-specific things to

learn, like the mapping
file syntax. Furthermore it's not a Cocoon component so it is 
non-trivial (although not too
complicated either) to integrate (for example have it use the Cocoon 
connection pooling
facilities). Yet I think it pays the price. Personally, it took me
about 
two weeks to understand
the thing and get it to work.

- The hibernate query language, HQL, that you have to use for fetching

objects that match
certain criteria (for fetching just one object there's a cool "load" 
method :-) is another obstacle.
Although it uses SQL-similar syntax whenever that's possible, it's
still 
hard to learn since there's
only the official documentation available that cannot compete with the

millions of articles and
books you can buy about SQL.

- Efficiency: The presence of another layer certainly does not make 
things more efficient. After
all, Hibernate queries and load()s have to be translated to SQL, too. 
But the most important point
seems to me that there are some subtile errors you can make that make 
perform

If you're looking to use cocoon professionally, you should seriously

I've tried and tried, but 2.1.5.1 build.sh simply doesn't work.
I removed the ant distributed with FC2 from RPM, despite the fact that

Note that if you use Jetty you won't have this problem.

I'd settle for being able to build 2.1.5.1 first.

You have an apache web server at port 80. The static content is there and
apache serves that up.  Configure apache to proxy the requests for
non-static content to tomcat/jetty for cocoon to process.

Response code: how can I get it?

[Thierry BARUSTA]

Hi!

I'm a newbie regarding the use of Cocoon and I would like to know how I
could test or make a selection on the response code.
I use the WebServiceProxyGenerator and I modified the code for not
leting it to process redirections (status 3XX) itself
(method.setFollowRedirects(false)) and depending on the response status
code I would like to have different behaviour.
It seems to me that it's not possible to do it in the sitemap directly.
Can I use actions to be able test the response code and forward the
modified response to the client? How?
I'm a bit lost in this new environement.

Thank you very much in advance,

/Thierry

This will not work indeed. cocoon.createWebContinuation() will create a new 
continuation that will resume directly after the point of creation. You could 
try something like this:

function redirectAndWait(uri, ttl) {
  var cont = new FOM_WebContinuation(new Continuation(),
 cocoon.continuation, ttl));
  cocoon.redirectTo(formatUri(uri, cont));
  FOM_Cocoon.suicide();
}

But I don't know where the 'Continuation()' comes from. Before I switched to 
my new flow engine I used to create a WebContinuation with 
'cocoon.createWebContinuation()' and check the request parameters to see if 
it's before or after the redirect:

function testingSome(uri) {
  var c = cocoon.createWebContinuation();
  print("Continuation = " + c.id);
  if (cocoon.request.get("afterRedirect") == null) {
cocoon.redirectTo(uri);
  } else {
print("Continued executing.");
  }
}

This way you have to make sure the user is redirected to the page with 
'afterRedirect' set (to 'true' for example). I think this way is less 
elegant, because the excution of the flow continuous after the redirect.

Re: Advantage using Hibernate with Cocoon

[Johannes Textor]

Hi Pat,
I have am now finishing my first project I used Hibernate and Cocoon 
together in,
so maybe you are interested in some thoughts from a beginner's point of 
view.

The issue Hibernate addresses is how to get objects to and from the 
database. When
I started to use cocoon, I was impressed by the possibility to separate 
design and
logic, using the sitemap and jxt/xslt for presentation and JavaScript 
flow control for
the control layer.

The most natural way to pass data to JX Templates seemed creating 
objects in JavaScript.
So I ended up writing objects - e.g. for articles sold in a web store - 
using JavaScript's
weird constructor syntax. The constructors used SQL statements to fetch 
the object's
data from a DB. Furthermore I had to define methods "update()" and 
"save()" for each
object to get the data back to the DB. These methods constructed SQL 
statements
containing the respective values.

That was more a PHP-like approach, where you are used to getting and 
storing data using
self-constructed SQL statements.

Now the principal advantage of Hibernate is that it creates a new layer 
where all the
persistency stuff is handled. From my point of view, this has the 
following advantages:

- You can use "real" Java to write your business objects, there's no 
more need to use the
awful JavaScript syntax and it has all the obvious benefits like 
supporting interfaces,
inheritance, etc. (Well that's possible without Hibernate too, but 
Hibernate *forces* you
to do this.)

- The flow layer is reduced to what it is supposed to do, controlling 
application flow.
Complicated operations that are to be performed on the business objects 
can be implemented
as Java methods. If you are familiar with Javascript, you will probably 
agree that it is not
all too well suited for writing large and complex programs, due to the 
lack of proper code
structuring facilities. Therefore I think, the thinner the control 
layer, the better.

- It's easier to change the underlying database. When writing native SQL 
statements, one
often tends to use propietary DB features like, for example, MySQL 
fulltext search (since
it's just so much easier to use than java search engines :-) However, 
this cannot be ported to
Oracle or Informix, for example.

The main drawbacks I see are the following:
- Yet another Elephant you have to eat: The whole concept of persistency 
is by no means
easy to understand. There's also a lot of hibernate-specific things to 
learn, like the mapping
file syntax. Furthermore it's not a Cocoon component so it is 
non-trivial (although not too
complicated either) to integrate (for example have it use the Cocoon 
connection pooling
facilities). Yet I think it pays the price. Personally, it took me about 
two weeks to understand
the thing and get it to work.

- The hibernate query language, HQL, that you have to use for fetching 
objects that match
certain criteria (for fetching just one object there's a cool "load" 
method :-) is another obstacle.
Although it uses SQL-similar syntax whenever that's possible, it's still 
hard to learn since there's
only the official documentation available that cannot compete with the 
millions of articles and
books you can buy about SQL.

- Efficiency: The presence of another layer certainly does not make 
things more efficient. After
all, Hibernate queries and load()s have to be translated to SQL, too. 
But the most important point
seems to me that there are some subtile errors you can make that make 
performance a nightmare.
For example, I had an article database that also contained other objects 
like stores, images, common
article attributes and the like. For convenience, I implemented a lot of 
two-way associations to make
navigation easier (e.g., I can fetch all the stores for an article and 
all the articles for a store just by
calling a Java getTheThing() method).

Now when querying for ONE article, hibernate per default fetches EVERY 
transitively available
object, since you might do something like

article.getStores().get(5).getArticles().get(3).getStores() 
and wow, now in fact the whole databases is fetched although you only 
wanted one article and
had no plans to navigate to a store !

Of course, this can be turned off, but IMHO it's a typical beginner's 
error :-) Just shows that you
have to think a little more when using Hibernate as opposed to native SQL.

Just my 2 Cents. I would enjoy further discussion.
Greetings,
Johannes

Hi Javier,

You can't access the I/O streams with a transformer directly.
A transformer won't get the complete document from its predecessor
component. It will rather get SAX events. Your component then can
manipulate the data of these events before passing them on to the next
component.

More concrete this means:

Extend the class org.apache.cocoon.transformation.AbstractTransformer
Override the method of the inherited Interface
org.xml.sax.ContentHandler.
Manipulate the incoming data and pass it then to the
super-implementation of AbstractTransformer.

The interface ContentHandler provides methods like startElement(),
endElement(), characters(), which corresponds to the opening tag,
closing tag and text node of an XML element.

For a complete list of available methods, please see
http://www.saxproject.org/apidoc/org/xml/sax/ContentHandler.html

Daniel

I've tried and tried, but 2.1.5.1 build.sh simply doesn't work.
I removed the ant distributed with FC2 from RPM, despite the fact that
it's clear from build.sh that it never goes anywhere near it, but uses
the ant distributed with Cocoon 2.1.5.1 instead. Now I get

./build.sh

loading user profiles from mysql

[Anton Andreev]

Hello,

I am running Cocoon 2.1.5 with Tomcat 5.0.19.  I'm
trying to load profiles for users from mysql (ver:
4.1.4-gamma-Max) rather then from filesystem (original
setup on cocoon).  So i've changed "load-user-profile"
 pipeline in portal/. to:


















instead of what is commented out.  I've checked the
pipeline and it returns exact xml just like in portal
xml files in profiles for user = "anonymous" and
profile = "copletinstancedata | layout".  In portal
sitemap it does not whant to work though.  The error
that i'm getting is: 
org.apache.cocoon.ProcessingException: Failed to
execute pipeline.:
org.apache.avalon.framework.CascadingRuntimeException:
Exception during loading of profile.

cause: org.xml.sax.SAXException: Parsing Error :
Premature end of file. Line : -1 Column : -1 {file:
[not available]; line: [not available]; column: [not
available]}

...although the xml it's getting is the same as in
profiles folders...  I would appreciate any
suggestions or new ideas...  Thank you...

Yes, Cocoon 2.1.5.1 won't compile because ant is apparently

and Tomcat 5.5 has issues running under Java 1.5.0 unless
you start adding patches.
If you're looking to use cocoon professionally, you should seriously 
consider using 2.1.5.1 - the 2.0.x branch is not actively maintained

That seems to work, after a bit of experimenting. Thanks very much.

For the record, with Tomcat 4.1.30 and Cocoon 2.0.4 with Java 1.4.2_05 
under FC2 you need to copy xalan-2.3.1.jar (only) from 
/opt/tomcat/jakarta-tomcat-4.1.30/webapps/cocoon/WEB-INF/lib (where it 
was put when Tomcat expanded cocoon.war) to
/opt/tomcat/jakarta-tomcat-4.1.30/common/endorsed

Copying xalan-2.3.1.jar to /usr/java/j2sdk1.4.2_05/jre/lib/endorsed
as suggested in the Wiki does *not* work.

Copying xercesImpl-2.0.0.jar in the same manner seems to be unnecessary,
as /opt/tomcat/jakarta-tomcat-4.1.30/common/endorsed already has a file
xercesImpl.jar. I have not tried removing this and replaing it with the
2.0.0 file.

The Wiki EndorsedLibsProblem is immutable, so I'll leave
it to someone else to update.

Hah! That definitely looks like it.

Unfortunately, the Wiki page doesn't say *what* files need
to be copied to the endorsed directory: it just says "the
libraries"; and it refers to a jre/lib/endorsed directory
which doesn't exist in my /usr/java/j2sdk1.4.2_05 directory
(do I create it?).

Re: Orbeon Presentation Server - OXF Rebuttal needed again?

[Damon Rand]

Why the bitterness? Competition is a good thing. Personally I am happy
that OXF has been opensourced. It is a good solid product and its main
weakness was not being opensource.

Having used both OXF and Cocoon on several projects they are both good
and both different. I believe OXF started out from Norman Walsh's
pipeline definition.
http://www.w3.org/TR/2002/NOTE-xml-pipeline-20020228/ 

The result is the almost complete eradication of java in the
presentation tier which is either a good or a bad thing depending on
your perspective. But the way I see it, it just means more choice for
web developers.

In some ways I find OXF is more like Struts than Cocoon -- I see it as
a way to bring my Struts colleagues across to XSLT pipelining rather
than as a replacement for Cocoon.

Looking through the comparison I cant find anything that is actually
untrue? I'm sure if there is anything specific then the Orbeon guys
will change it.

cocoon\build\cocoon-2.1.5.1\classes\org\apache\cocoon\components\flow\javasc
ript\fom\fom_system.js, the sendPageAndWait method is really a sendPage call
with some extra stuff, just like you said:

FOM_Cocoon.suicide = new Continuation();

FOM_Cocoon.prototype.sendPageAndWait = function(uri, bizData, fun, ttl) {
this.sendPage(uri, bizData,
  new FOM_WebContinuation(new Continuation(),
  this.continuation, ttl));
if (fun) {
if (!(fun instanceof Function)) {
throw "Expected a function instead of: " + fun;
}
fun();
}
FOM_Cocoon.suicide();
}

It seems it's FOM_Cocoon.suicide(); that halts execution (duh). I tried
using this:

function testingSome() {

var c = cocoon.createWebContinuation();
print("Continuation = " + c.id);
FOM_Cocoon.suicide();
print("Continued executing.");
}

When I call this test method, it displays a continuation id and then halts.
When I call the continuation using the print'ed continuation id to resume
execution, it seems it's picking up execution right after the
createWebContinuation() call, which means it only prints the "Continuation =
" again and then executes suicide - whereas I wanted it to pick up right
after its suicide line and print the "Continued executing." part.

I guess I'm supposed to use this in some other way, but I'm not that
familiar with flowscript. What am I doing wrong?

  Ulf Sahlin

Cocoon Proxy & Redirects

[Thierry BARUSTA]

Hi!

I'm curently using the WebServiceProxyGenerator provided with Cocoon
2.1.5. I have an issue when receiving a 3xx response code. The redirect
is processed by Jakarta Commons - HttpClient and it works fine. The
problem is that the url in the client's browser doesn't change (which is
normal because it doesn't see the redirect) and the different request
variables (contextPath, requestURI...) are set with the first request
values. I need therefore to let the browser taking care of the redirect
itself with a "proxied" location.

I'm quite new to Cocoon and I don't know how to perform that:
-by selecting on http response code and forward it to the client browser
with a proxied location url, is that possible?
-by modifying the WebServiceProxyGenerator code?
-by other better ways?
 
This might be a bug in cocoon's proxy block. Thank you very much in
advance.
Any help appreciated!

Re: cocoon 2.1.5.1 and tomcat 5.5, library conflict

[Niko Popitsch]

Hi,
I still could not solve this problem, but I found out that it _is_ a 
conflict between the commons-logging-api.jar in the tomcat/bin directory 
and the commons-logging-1.0.3.jar of my application.
But how to get around this conflict? the libraries in tomcat/bin are 
loaded by the tomcat system classloader (because they are used in the 
startup routines of tomcat, I presume).
My webapp is loaded by the WebappClassLoader (see the debug output below)...

Unsing the endorsement mechanism for overriding the 
commons-logging-api.jar does not work (a missing constructor...).
I also tried commons-logging-api-1.0.4.jar - same thing.

anyone?

handle errors -> send exception to action

[Gunter D'Hondt]

Hello,

I want to send an email when an exception
occurs and inside the mailbody the exception stacktrace must be written.
So I thought to make an action "action-sendmail" and call it
from the map:handle-errors part. That definitely triggers the action but
how can I send the Exception object (or just the errormessage and its stacktrace
to that action so I can place it into the mailbody.

Can the Exception object been sent thru
a parameter? Where is the exception located? Inside the request object?

See below a snippet of the sitemap

Any help is welcome,

I think there are advantages in using Hibernate to implement data 
persistence over a relational database whether you are using Cocoon or 
not. Cocoon's concern is presentation and flow control. Hibernate's 
concern is persistence. The two concerns should not overlap, so that 
you could use a different presentation layer on top of Hibernate or a 
different persistence mechanism beneath Cocoon easily.

We happen to be using Cocoon and Hibernate simply because we believe 
them to be the best tools in their respective fields of application.

There some articles on the web, about using
Hibernate with Cocoon.
And anyone using it?
Articles, not that I know of, but you can find a complete sample here: 
. And if you'd like to 
attend either OSCOM4 [1] or GT2004 [2], I'll be presenting a talk on 
Cocoon and Spring which will also cover Hibernate.

RE: Problem dealing with & ampersand - HELP

[Philip . Fennell]

Hello,

> I cannot possibly put in some entity reference because the href is
user input driven

If the href is user input driven then you have two choices:

1) Upon submitting the form, that sends the user input, use the onSubmit
event to trigger some client-side scripting that converts troublesome
characters in the URL into HTTP encodings e.g. (& = %26)

2) If the output of your JSP page is generating some markup that is then
being processed by a cocoon pipeline, do something similar in your JSP.



Hope this helps.

Modifying documents via flowscript...

I am using flowscript to handle the process around 
modifying a form - so far so good!  Now I would like
to be able - from flowscript, I suppose - to modify the
just-saved form in some way, probably by appending
a comment line to the end (say with a time and date
stamp, and an user id).  Is there a straightforward 
way of doing this?

Thanks

Can you take the output of a transformation and use it as a param eter within the context of the matcher???

[Philip . Fennell]

Wasn't sure how to word the subject but what follows is what I'd like to
know...

I have a pipeline that contains a matcher the uses the parameter
(relativePath) from the request as the url of a redirect:



  
  
  

  
  http://localhost:8080/cocoon/RIU/{relativePath}"/>

  
  



What I'd also like to do is take the result of a transformation, in this
case a url and use it as a parameter (relativePathFromOtherTransform) in
a redirect as above:



  
  
  

http://localhost:8080/cocoon/RIU/{relativePathFromOtherTransform}"/
>

  
  



The only thing here is, how do I get my hands on the serialized (text)
output of a transformation either from within this matcher or from some
other matcher and use it as a parameter.


Could this be done or am I just mad as bag of snakes???

var roomid = jxpathContext.parentContext.getValue("../../@id");
var formValue =

jxpathPointer.setValue(formValue); }

As you can see my @path should be relative to the room it is in
So on bind I would like to retreive the id of the room it is in ;)
but I cant go back further than  which is the parentContext on the
JXPathContext, var roomid = jxpathContext.getValue("../../@id") doesn't
work , neither does the one above ??? 

hm, I'm only assuming that the pathContext used above does the same as 
an additional ../ in front of the path, so the equivalent should have been:

var roomid = jxpathContext.getValue("../../../@id")
is this possible or do I really have to do a post bind transformation ??
I'm sure there's a way to XPoint at the whole binded document??
there is no immidiate reason I can think off why this shouldn't work, 
close up testing should yield more hinting messages..

just to make sure I made some tests based on the form2 sample included 
with the cocoon distro

see:
http://cvs.apache.org/viewcvs.cgi/cocoon/trunk/src/blocks/forms/samples/forms/form2_bind_xml.xml?rev=30942&root=Apache-SVN&view=auto
inserting at line 101 something like this:
  var testValue = 
jxpathContext.getValue("../../../info/email/@boolBindingWorks");
  print("xpath-test 1 returns: " + testValue);
  testValue = jxpathContext.getValue("//email/@boolBindingWorks");
  print("xpath-test 2 returns: " + testValue);
  testValue = 
jxpathContext.getValue("ancestor::context/info/email/@boolBindingWorks");
  print("xpath-test 3 returns: " + testValue);

just works for me, I know it's slightly different to what you do, but 
this shows there is no navigation limitation to the xpath expressions.

a slower xpath search that removes the need to get the number of keading 
../ levels correct for testing could be 
jxpathContext.getValue("anscestor::room/@id")
