Re: Not handle the XML header in the sax parser

[Heiko Milke]

Hey there,

well actually i dont recommend doing that but here is a way to do it.

You simple write yourself a documenthandler transmitter or whatever you
call it (i named it FragmentHandler in the Example):P

--
public class FragmentHandler implements ContentHandler {

ContentHandler parent = null;
public FragmentHandler(ContentHandler parent) {
this.parent = parent;
}
}
--


you have to implement ALL memberfunction of the ContentHandler interface
and send all the events to the parent like this.

--
public void characters(char[] ch, int start, int length) throws
SAXException {
parent.characters( ch,  start,  length);
}
--

and in the last step you simply catch the startDocument and endDocument
events and dont tell the parent 


BUT like i said i'd only use it for testing. You never know which
complications you can get into with this =))


Greetings Heiko

Re: AW: Accessing session variables in the sitemap.xmap

[Heiko Milke]

Hello Marco,

thank you very much for your reply. It is a bit irretating that you
can't read something from the session that was set to it earlier in a
serverpage (while working on the same request) but i'll have to live
with it.

Now I wrote an action that does the talking to the session and it works
fine. The serverpages just lost some of their value for me. I was so
happy with the XMLFragment implementation of mine working out so well
but if session modifications are delayed to the next page request 

Gn8 Heiko!

Re: Accessing session variables in the sitemap.xmap

[Heiko Milke]

Hello Christian,

Thank you very much!

It's good to know that it is impossible. I already guessed that.

I'll write an action and see how it works out.

Bye Heiko :)

Re: Accessing session variables in the sitemap.xmap

[Heiko Milke]

Hey Andrew,

Thanks for all your help! But well, it still aint working :(

I tried on several browsers. I tried in the mount directory and i tried from
the main sitemap. None if it works.

Im using cocoon version 2.0.4 (on Windows 2000).

Yes I did.

And if i "echo" the value from "selected_stylesheet" in the xsp page then it
is correctly set. The sitemap simply doesn't get notified about the new
session variable. =(

sadly this doesn't change much.
I still get "resource not found"

Like i said i guess its a special problem with sessions that were just
created. If i come from a different page where i already set the
"selected_stylesheet" then it works.

The timeline looks broken. Whatever is done to the session in the generator
doesnt come to the sitemap.

Accessing session variables in the sitemap.xmap

[Heiko Milke]

Hello,
 
I want my application to work like the 
following.
 
 
    

 
 
1. the serverpages generator accesses a script 
named "xsp/example.xsp"
Withing this script a session variable named 
"selected_stylesheet" is set.
 
xsp/example.xsl
 
2. In the next step i want to transform the 
generated data using the stylesheet whose path is stored in the session 
variable.
 
3. finally i want to serialize and close the 
pipe.
 
 
This one is not working. Cocoon complains about a 
resource that cannot be found. Actually it can't find  the stylesheet. 
Its all about coming to the page for the first time. Im creating the session in 
the serverpages - generator. But somehow the sitemap doesnt get it.
 
---
 
Thats why i did this one right here :
 
                
        
        
    
    

 
 
the descriptor file looks like this:
 
  

 
 
I expected cocoon to find out that, when coming to 
the page for the first time, even if there is no "selected_stylesheet", that it 
can get the default parameter  from the descriptor and get 
lucky.
 
 
This one aint working too.
 
What am I supposed to do to make it work 
?
Maybe it would be a good idea to create the session 
earlier, maybe before i enter the pipe but i dont know how to do 
that.
 
 
Thanks in advance
 
Heiko.
