Title: RE: Can cocoon write pdf to a file?





will this code get .pdf file over HTTP? 
if yes, then wouldn't it be more efficient if instead of that, you somehow directly write on the hard disk without loading a Web server?

 Subject: Can cocoon write pdf to a file?
 
 
 Is it possible for Cocoon to do an XML+XSL - PDF transformation, but
 instead of serving the PDF into the browser, writing it to a file?
 
 What I would like to do is, take information entered into a form on a
 jsp page, turn it into an XML file, and then apply my XSL to it to
 produce a PDF which is then stored to disk on the server.
 
 Can this be done using Cocoon, or would it be easier to just use FOP
 embedded in a servlet? If it can be done, what do I have to do?

Yes! you want SourceWritingTransformer from Cocoon 2.1 dev.  There is a 
parameter to tell it how to serialize the output.  It writes to a file 
on the local hard drive.

 Is this feature available in the scratchpad of C2.0.3?

Yes, just checked and it's in scratchpad of 2.0.3.
From the java docs:

This transformer allows you to output to a WritableSource.

Definition:
map:transformer name=tofile
src=org.apache.cocoon.transformation.SourceWritingTransformer
 map:parameter name=serializer value=xml/  
!-- this is the default Serializer (if your Source needs one, like for
instance FileSource ) -- 
/map:transformer/

Invocation:

map:transform type=tofile
  map:parameter name=serializer value=xml/
/map:transform

Input XML document example:

page xmlns:source=http://apache.org/cocoon/source/1.0;
  ...
  source:write src=context://doc/editable/my.xml
page
  XML Object body
/page
  /source:write
  ...
/page

Output XML document example:

page xmlns:source=http://apache.org/cocoon/source/1.0;
  ...
  source:write src=/source/specific/path/to/context/doc/editable/my.xml
result=success|failure action=new
 source specific error message

RE: Can cocoon write pdf to a file?


Sure.
The main pipeline continues but the portion of XML
corresponding to the SWT has been replaced by the result
of the SWT step.
 
Input:
...
source:write 
 content_to_write
 ...
 /content_to_write
/source:write
...
 
Output:
...
source:result isSuccess='true'/
...
 
Note: this is not the correct syntax, at all. But this is the idea :-)

RE: Can cocoon write pdf to a file?

Title: RE: Can cocoon write pdf to a file?





I still don't see how this will work with PDF.


PDF comes only from FOPSerializer. the last step in the pipeline. So, if you want to write its result on the disk, how can SWT be useful?

I thought, maybe it makes a sense to have a special type of transformer or serializers, which would save output on the hard disk, but pass the URL to the pipeline. so, there'll be uniform way to deal with this sort of situations.

on the other hand, having the caching configured properly would probably solve the problem too.

RE: Can cocoon write pdf to a file?

right, and the output of the cocoon pipeline gives the result of the output
which you can transform into a report back to the user who called the
action, or ignore it entirely.

 Sure.
 The main pipeline continues but the portion of XML
 corresponding to the SWT has been replaced by the result
 of the SWT step.

 Input:
 ...
 source:write 
  content_to_write
  ...
  /content_to_write
 /source:write
 ...

 Output:
 ...
 source:result isSuccess='true'/
 ...

 Note: this is not the correct syntax, at all. But this is the idea :-)

 isn't there to be a serializer after the transformer in the pipeline?

  Subject: RE: Can cocoon write pdf to a file? 

Yes! you want SourceWritingTransformer from Cocoon 2.1 dev.  
There is a 
parameter to tell it how to serialize the output.  It writes 
to a file 
on the local hard drive. 

   SWT can have its own serializer? What a great stuff! 
   Is this feature available in the scratchpad of C2.0.3? 

  Yes, just checked and it's in scratchpad of 2.0.3. 
  From the java docs: 

  This transformer allows you to output to a WritableSource. 

  Definition: 
  map:transformer name=tofile 
  src=org.apache.cocoon.transformation.SourceWritingTransformer 
   map:parameter name=serializer value=xml/  
  !-- this is the default Serializer (if your Source needs 
  one, like for 
  instance FileSource ) -- 
  /map:transformer/ 

  Invocation: 

  map:transform type=tofile 
map:parameter name=serializer value=xml/ 
  /map:transform 

  Input XML document example: 

  page xmlns:source= http://apache.org/cocoon/source/1.0
 http://apache.org/cocoon/source/1.0  
... 
source:write src=context://doc/editable/my.xml 
  page 
XML Object body 
  /page 
/source:write 
... 
  /page 

  Output XML document example: 

  page xmlns:source= http://apache.org/cocoon/source/1.0
 http://apache.org/cocoon/source/1.0  
... 
source:write 
  src=/source/specific/path/to/context/doc/editable/my.xml 
  result=success|failure action=new 
   source specific error message 
/source:write 
... 
  /page

RE: Can cocoon write pdf to a file?


well, the SWT writes to a WritableSource, AFTER being serialized by its OWN
serializer.
So the main pipeline can be a HTML report of the PDF written to disk.

I still don't see how this will work with PDF. 

PDF comes only from FOPSerializer. the last step in the pipeline. So, if you
want to write its result on the disk, how can SWT be useful?

I thought, maybe it makes a sense to have a special type of transformer or
serializers, which would save output on the hard disk, but pass the URL to
the pipeline. so, there'll be uniform way to deal with this sort of
situations.

on the other hand, having the caching configured properly would probably
solve the problem too.

Wait, this last statement makes it sound like you are only interested 
in keeping the results cached to reduce load.  If that is the case, 
use cocoon caching - it will automatically keep the result in memory and
optionally write it out to disk/database as well.  Caching will not keep 
a .pdf file anywhere - it remembers (compiles in docs is misnomer) 
the byte-stream for reuse if appropriate.  I would highly reccomend against 
attempting to introduce your own file-based caching system when a good one 
is already in place.

Hopefully, that's not what you meant by that.

I wonder if Cocoon (2.1?) handles Last-modified management?
So when the browser requests something, Cocoon can
(automatically or via custom actions) provide a Last-modified,
and the client then decides if he can use its cache.

I read that Cocoon handles Expires. But Expires and Last-modified
are different notions.

Title: RE: Can cocoon write pdf to a file?

well, I don't remember who started the thread, not me though :)

I'll also need some sort of solution with large PDF files. The idea is that you come and launch report, and given a URL to check it later (when PDF is ready). The URL would point to a file on the disk, which will be stored for some time, say one day.

Cashing is for a different situation, which you described.
