Here's a work-around which worked for me (not a nice one, I know): - to fix the NPEs: I have replaced the cocoon 2.0.4 files by the 2.1m2 ones for AbstractDOMFragment and DOMStreamer as well as replace the uri null value for the fragment-id attribute in FragmentExtractorTransformer by an empty string.
- to fix the message "Could not find fragment ..." in FragmentExtractorGenerator: add logic to delete the document fragment after the SECOND request or (in case of using Netscape) after 5 minutes. - to remove java.net.SocketExceptions from core.log: try/catch around doc.generate() in FragmentExtractorGenerator eating all java.net.SocketExceptions. - to remove java.net.SocketExceptions from error.log: CocoonServlet.java: logic to check before writing a log record whether there was a java.net.SocketException -----Ursprüngliche Nachricht----- Von: Christian Kurz [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 4. Juni 2003 22:58 An: [EMAIL PROTECTED] Betreff: All hope lost: Can FragmentExtractor serve SVG images to IE (socket write error) ? 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-dev&m=101994024218728&w=2, http://marc.theaimsgroup.com/?l=xml-cocoon-users&m=103907382827236&w=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.
