WriteDOMTransformer

[Ivan Rubin Ayma]

Hello,

I have to generate some content, write it to the session and redirect to
another pipeline.

I can't do that! If I don't serialize, the events does not flow through
the pipeline and through WriteDOMSession transformer.

Do I have a way to accomplish that, or should I change my logic?

Thanks,

ReadWriteDOMsession

[Ivan Rubin Ayma]

Hello,

I have a login page. The form points to a do-login pipeline

I want do-login to authenticate the user through an action, that's ok,
and then generate an XML with a menu, write a DOM on the session and go
to the main pipeline.

The main pipeline, in between a number of things, reads the dom from the
session and makes use of it.

The problem:

Database

[Ivan Rubin Ayma]

Hello,

My generators use to communicate with a database through JDBC and now I
have to make Windows NT authentication, so the JVM running the system
have to be running on super-user mode, but I don't like the idea of
running everything on super user. 

I would like to just run the database layer, or database+logic (pretty
complicated at this moment) on super user mode. How to communicate with
that layer? RMI? 

Can you point me to some information on this matter, I think it is a
common one in every system.

Sorry if this is not a strict Cocoon post.

Thanks,

RE: IllegalAccessException: Object is not a Component

[Ivan Rubin Ayma]

Christian,

Remove every reference to your component everywhere but from the cocoon
classloader, as to hide it from any different classloader but that one.

To use the cocoon classloader and to pass parameters to it, you're in
the right place, the initparams at web.xml

RE: Simple XSL question

[Ivan Rubin Ayma]

Simone,

Just for the record, I went on using this template.


  

  


I still wonder if it is not a bad design to generate a base xml at the
begining of the pipeline, aggregate other generated xml data and then go
into a number of transformations for each specific section of the base
xml, transforming them with the other generated data, and copying all
the unused data, in each transformation, for the rest of the pipeline,
basically in terms of performance. By now, that's what I'm doing.

Thanks,

You can create a "catch all" template with lower priority, for example :


 something



 


This means that if "something" is found, it will be processed by the
first 
template, if "else" is found it will be processed by the second
template, 
which does a copy. The lower priority is an optional, since the XSLT 
processor should use the first template since it's more specific, but
I've 
had some strange results, and forcing it is a good idea.

I'm not sure about the  ... it could cause some

Generators

[Ivan Rubin Ayma]

It would be useful for me to use more than one generator at the
beggining of a pipeline, as I have to generate pretty different things

There's a way to do it?

RE: how to add extra classes into cocoon's classpath?

[Ivan Rubin Ayma]

I'm on the same environment.

These are the two parameters I modified on
webapps/cocoon/WEB-INF/web.xml


  init-classloader
  true



  extra-classpath
  c:\Zeus


for using my own cocoon components.

I think the status page of cocoon shows the classpath cocoon is using,
and if it is ok, it have to be the way you invoke the classloader.

RE: how to add extra classes into cocoon's classpath?

[Ivan Rubin Ayma]

With Tomcat WEB-INF/web.xml there's an init-param, commented with de
default distribution, to add classes to the cocoon's classpath. 

You should check the class-loader param for Cocoon to use its own class
loader if you keep on having problemas loading classes.

RE: Object X is not a component error

[Ivan Rubin Ayma]

I solved it.

Sorry for bothering with environment questions.

. First of all I changed to Sun's VM, invoking Tomcat 4.0.1 with it.

. I added the classpath of my own Cocoon Components into the web.xml of
Cocoon, on the  named extra-classpath

. And I needed to set the  named init-classloader on the
same web.xml to true, for cocoon to use his own classloader.

This explains everything. Yes, it is instance of *this* particular
instance of the Component class, but *not* the instance of the Component
class loaded by Cocoon. You have got *two* instances of the Component
class. Avoid instantiating of the action outside of Cocoon, or do it
using Cocoon's class loader. Any of these two should help.

Java might have more then one *instance* of class loader. Even *same*
class file loaded by two different instances of the class loader is
*different*.

Try System.getIdentityHashcode() on your Component.getClass() and
Cocoon's Component.getClass() - this will be two *different* classes.

Sitemap reloading

[Ivan Rubin Ayma]

My root sitemap does automatic reloading when I change it, synchronious,
as specified on cocoon.xconf, but my sub-sitemap behaves completly
different, it does reloading when he wants, or something like that.

Any hints?

RE: Object X is not a component error

[Ivan Rubin Ayma]

Vadim,

It helps me a lot. But I'm still a wandering rock! And keep on walking
as follows:

I instanciated my class outside cocoon, in the same project (same
parameters to the VM), and checked for instance of Component and it's
ok, it's an instance of:

org.apache.avalon.framework.component.Component

On my sitemap, if I replace my action for, for example,
org.apache.cocoon.acting.HelloAction, sitemap compilation goes ok.

So the problem should be my environment, which is not the best, but is
simple.
I'm using JBuilder to run Tomcat and Cocoon with jars.
I've included on the project all the tomcat jars and the
web-apps/cocoon/WEB-INF/lib/*.jar, where the avalon framework is
located.

I think the compilation of my component can't be the cause. I'm
compiling it with JBuilder's compiler.

More than one Component class? from where? I'm just using tomcat 4 jars
and cocoon 2 jars...

Different ClassLoaders? I don't quietly understand that, doesn't Cocoon
use the Java ClassLoader of the virtual machine running it? I see a
components.classloader package in cocoon, that's the class loader it
uses? Can the cause be that that classloader is not compatible with the
class loader of the virtual machine (JBuilder's VM) running it?

Thanks,

Asunto: RE: Object X is not a component error


This exception is thrown when your object does not implement Component
interface:
 if (!(jSessionLogin instanceof Component)) throw
IllegalAccessException();

Usually this happens when your component does not implement (IIRC)
org.apache.avalon.component.Component. Also it happens when you have
*more* then one class Component loaded by Java due to use of different
ClassLoadrers and/or several class files for the same Component class.

I'm not sure that this could help you, but I don't know what's going
wrong on your system and can't suggest you anything right now.

I wrote the simplest component I could and at sitemap-compilation cocoon
keeps on giving me:

Error in sitemap configuration : Object Zeus.core.cocoon.JSessionLogin
is not a Component

Why?

The component:

public class JSessionLogin extends
org.apache.cocoon.acting.ComposerAction implements ThreadSafe {

public Map act( Redirector redirector, SourceResolver resolver,
Map objectModel, String source, Parameters par )
  throws Exception {

return null;
}
}

It's well compiled and in the right place.

Any hints?

Thanks,

Try ServerImpl from the CVS. Should work Ok now.

Simple XSL question

[Ivan Rubin Ayma]

Hello,

How can I make a XSLT transformation of just a couple of elements,
leaving the rest untouched, without having to select everything and
passing it through?

I'm trying to create pipelines involving a number of transformations
with a specific task each.

Thanks,

It's a way?

[Ivan Rubin Ayma]

Hello,

I have to make a web interface to an existing database java application.

The app is divided in a number of Data clases, that represent a table in
the DB, Win classes to show that data in differente ways in a swing
window, and Form classes to add-modify registers.

I think Cocoon is a good way to do this, my idea is to use those Win
classes and Form classes as generators, generating the XML
representation of the data and the information requiered to show it in a
window and as a form, and then use XSL transformations to convert that
to HTML and apply all the navigation issues.

Do you think is a viable approach?

Thanks,

Ivan

RE: Help me....

[Ivan Rubin Ayma]

Check out the site map, sitemap.xmap, and the documentation for it.

You have to specify there the structure for your application.

An improvment (!) on cocoon 2. A headache, but an improvment, I assure
you. Centralization.

Asunto: Help me


Hi ,

 I have installed Cocoon 2.0 on Tomcat 4.0 i.e Catalina. I am able to
get
the required page when I give:
  http://localhost:8080/cocoon/

But one thing I could not understand is, Where to put the applications
that
we have developed i.e I have a set of XML ,XSL's . In which folder
should I
put them in order to view them in the browser ?
   I have created a folder called 'wap' in 
  %Tomcat%webapps/cocoon/wap and put them in that folder. When I give
the
url :
  http://localhost:8080/cocoon/wap/stock.xml 
  I am getting the error ..." The page can not be found " .

My doubts are:
 The way I have followed is correct or not ?
 Do I need to put them in Cocoon  and give  path to that
folder
 in Tomcat server.xml?
 If so where should I put them in Cocoon.? 
>From where can I get the examples using Cocoon and how to run them with
Tomcat 4.0 ?
  
Please help me in this matter.

  Thanks in advance..

regards
Malathi
