Hi,
You seem to be missing certain jar files on the classpath.
Specifically, the batik-ext.jar file in the lib directory (if you
downloaded the binary distribution.) You can copy this to your
project's lib folder and add it to its classpath through Project ->
Properties -> Java Build Path -> Libraries and Add External JARs, or
by modifying the .classpath file.

I am relatively new to Java and very new to SVG. I wrote a small svg-based
program using Eclipse to experiment with Batic's bridge, but it does not
want to compile and this is probably due to my lack of skills with Eclipse
(sorry).
Any comments why Eclipse can not find ... import
org.w3c.dom.svg.SVGDocument; in the attached code?
msg:
"The type org.w3c.dom.svg.SVGDocument cannot be resolved. It is indirectly
referenced from required .class files"
Your help is greatly appreciated,
