It is alpha. But when you test your pages and they work, it's OK. Currently 
I'm using cocoon only to generate static pages, and for this it's OK. For 
servlet mode, it's still to slow for me.

TK To my 2.0 times I also had the problem. The problem was gone since I
use 
TK cocoon 2.1. I guess it has something to do with pipeline caching,
but TK have never tested.

Torsten,

thanks for the quick feedback.

My understanding was that 2.1 is still alpha. Do you have any system in
production, yet? We are quite close to release date...
 
Best regards,
Christian

  All of this works fine when requesting the page using Netscape
Navigator
  (valid page and images, no errors in log file). As soon as I use the
  Microsoft Internet Explorer to request the same page, the HTML page
is
  returned, but the svg image has not been served properly. According
to
  the log file there was a java.net.SocketException: Software caused
  connection abort: socket write error (details included below),

I remember that other software (Squeak) had a somewhat similar problem
which
was solved by changing something in the networking layer. The browsers
were
different regarding opening new connections. I think Netscape created
one
connection to download one file after another while MSIE created a
connection for every single file on a webpage. Something like that. It
took
some time to fix that problem...

Thank you, Andreas.

I am afraid this is way too deep for my java skills. You don't have any
source code files/ changes by any chance?

Best regards,
Christian

Yes, works great on konqueror, netscape (mozilla), ie 5.5 and ie 6. Didn't try 
others.

CK -cocoon (2.0.3, 2.0.4),

All hope lost: Can FragmentExtractor serve SVG images to IE (socket write error) ?

2003-06-05 Thread Christian Kurz 
Hi,

has anybody successfully served svg images (not svg rendered as JPG or
PNG, this just works great!) to the IE using the FragmentGenerator? I
would really appreciate any information or code snippets about sitemap
setup and versions used (OS, JDK, Tomcat, Cocoon, Xalan). 


After trying to fix what I though was a simple problem for 1.5 weeks I
have got no ideas on how to investigate anymore:

I am trying to serve a generated svg image as an svg file. The two
pipelines are basically:

FileGenerator
XSLT-Transformer to turn xml data into a xml document containing

Custom-Transformer for calling GraphViz to create SVG elements
in xml document
XSLT-Transformer
FragmentExtractor
XSLT-Tranformer 
HTML-Serializer

FragmentGenerator
SVGXML-Serializer

All of this works fine when requesting the page using Netscape Navigator
(valid page and images, no errors in log file). As soon as I use the
Microsoft Internet Explorer to request the same page, the HTML page is
returned, but the svg image has not been served properly. According to
the log file there was a java.net.SocketException: Software caused
connection abort: socket write error (details included below), in
certain configurations I am receiving a NPE in DOMStreamer.stream
instead (details included below). As discussed in other threads
(http://marc.theaimsgroup.com/?l=xml-cocoon-devm=101994024218728w=2,
http://marc.theaimsgroup.com/?l=xml-cocoon-usersm=103907382827236w=2),
this looks like IE requesting the svg twice and aborting the first
request causing the trouble. Is the FragmentExtractor able to handle
this, if the serializer is not JPG or PNG?

I am using WinXP and have tried various configurations: 
-cocoon (2.0.3, 2.0.4), 
-Tomcat (4.1.24, 4.1.18)
-JDK (1.4.0_02, 1.4.1_02)
-XALAN (2.3.1, 2.4.1, 2.5.1) and SAXON (6.5), 
-incremental processing turned on and off.

Any hints, ideas on further research very much appreciated.

Thanks in advance,
Christian
