Subject AW: How to force Batik to use the Xerxes Parser when transforming from SVG to JPEG?
Date Mon, 31 Jan 2005 11:16:50 GMT
Hi Thomas,

sorry for my delayed answer:

This is my solution for forcing Batik to use Xerxes:

  JPEGTranscoder t = new JPEGTranscoder();

       t.addTranscodingHint(JPEGTranscoder.KEY_XML_PARSER_CLASSNAME,"org.apache.xerces.parsers.SAXParser");
       t.addTranscodingHint(JPEGTranscoder.KEY_XML_PARSER_VALIDATING,new Boolean(false));
              
       t.addTranscodingHint(JPEGTranscoder.KEY_DOM_IMPLEMENTATION ,SVGDOMImplementation.getDOMImplementation());

  

Now I get this error when I use the class on the server:
Mon Jan 31 09:40:52 CET 2005:<E> <ServletContext-General> Servlet failed with
Exception
java.lang.NoSuchMethodError

It works when I use the class locally. Where should be something wrong with the libraries,
but I'm using 
all the new versions of batik and xerxes.

Does anybody have a suggestion?

Thanks

Hi Christian,

    First off the default parser for Batik has been
Xerces for a very long time.  I really only mention this
because since then there have been many improvements in Batik.

    The problem is that Batik doesn't use JAXP to pick it's
parser (JAXP didn't exist when Batik was written).  The
way to change the parser is to modify or override the
file:

     org/apache/batik/util/resources/XMLResourceDescriptor.properties

    You can either modify the one in batik (located under
xml-batik/resources) or add one to your classpath ahead of
the one included in 'batik-util.jar'.
