Subject Batik problems in Cocoon 2.2
Date Tue, 19 Oct 2010 20:05:43 GMT
  Hello, I'm trying to get Batik 1.7 running in Cocoon 2.2. I think I 
should start from the beginning.

I'm moving from Cocoon 2.1 to 2.2 (2.2 uses maven for everything), I 
created the webapp and tried to use the fop-block in cocoon but the fop 
version it wants to use is 0.20.5 and batik-1.6. The problem is that 
with that combination embedded SVGs wont work in fop. I downloaded the 
fop-ng-block and now have a working cocoon 2.2 with fop-1.0 and batik-1.7.

My problem is that now the SVGSerializer (converts SVG to jpeg) part of 
cocoon does not work. It gives me the following error:


The problem is in this part of startElement() for some reason, parser is 

         if (inProlog) {
             inProlog = false;
             try {
                 isStandalone = 
             } catch (SAXNotRecognizedException ex) {
             try {
                 xmlVersion = (String) 
             } catch (SAXNotRecognizedException ex) {

I moved both trys to the createDocument(InputSource is) since it just 
saves those 2 values (why are those trys in startElement and not 
After moving both trys thingts moved along and it crashes on the 
transcoding part. The error I get is:

java.lang.ClassCastException: org.apache.batik.dom.GenericElement cannot 
be cast to org.w3c.dom.svg.SVGSVGElement

the code for transcode is:

     public void notify(Document doc) throws SAXException {
         try {
             TranscoderInput transInput = new TranscoderInput(doc);
             // Buffering is done by the pipeline (See 
             TranscoderOutput transOutput = new 
             transcoder.transcode(transInput, transOutput);
         } catch (TranscoderException ex) {
         } catch (Exception ex) {

after reading through a lot of posts I found one saying 
DOMUtilities.deepCloneDocument would convert dom to Batik's own DOM and 
do the transcode. I changed the TransocderInput constructor to this:

TranscoderInput transInput = new 

but it still gives me the same error, so I'm officially stuck. I hope 
someone here can help me, asked at the cocoon list 3 times and got no
