I am trying to transform the flowText.svg given in the
samples/extensions directory and transforming into pdf
and it is producing me a pdf without any text. Is
there anything that I should do specially to
incorporate the text wrapping stuff into my pdf ?

I created BatikElementMapping and BatikObj objects and
added this entry in the driver class. I am getting the
following exception. Can anybody help ?

I think you need only an element mapping class, you can probably
reuse SVGObj/SVGElement.

I don't think so. IIRC the SVGElement temporarily holds a SVG
element node, and a proper stylable DOM is generated from them
further down the stream.

Well, I have looked through the Driver and
SVGElementMapping classes and concluded that in order
to create batik extension support in FOP, I need to
create similiar classes of SVGElementMapping, SVGObj
and SVGElement in the FOP src and then register them
with the FOP driver class. Are these conclusions valid
and also, are there any changes I need to do in batik
src ?

The DOM for instream-foreign-objects is built by FOP. The
current code uses an explicit mapping to a maker class for
this. You'll have to provide an element mapping class as
well as a maker class for any extension elements. The
mapping class can be registered as a service as well as
explicitely supplied to the Driver. Look into the source
fo rthe Driver and the SVGElementMapping for hints and
examples.

I did put the batik-extension.jar, batik-svg-dom.jar
in the classpath and then tried to convert into pdf.
If I externally reference the svg file, everything
works fine but if I embed the svg file in my fo
document, it produces a blank pdf with the following
errors:
Unknown Formatting Object
http://xml.apache.org/batik/ext^flowText
Unknown Formatting Object
http://xml.apache.org/batik/ext^flowRegion
Unknown Formatting Object
http://xml.apache.org/batik/ext^region
and so on.
How can the same svg work well when externally
referenced but not work when embedded in an fo
document? Can anybody help ?

I've never tried to do this, however I am surprised at this result
since from the pdf converters point of view the flowText is
indistinguishable from other SVG text.
Can you view your SVG in the browser?
Are you including the extensions on your classpath? Normally we
do not include the extensions in the class path for our tools since
they are not conformant SVG (at least not yet).
All of which get's to how are you invoking the pdf transcoder?
