Using dynamic SVG with FOP

[Markus Alin <ma...@swissrisk.com>]

Hi All!!

We are currently building a reporting application featuring PDF
generation with FOP. Within the FOP we call a url generating a jpeg
image by transforming a XML into a SVG and by serializing this into a
jpeg. This works perfectly for static jpegs but by the start of the jpeg
matcher the application does not seem to have a session and therefore no
XML can be generated (we user readDOMSession transformers). This
ofcourse works perfectly when calling the jpeg pipeline stand alone but
it does not work when calling it from inside the XSLT stylesheet
generating the FOP.

Any ideas how to solve this???

The calling code and the jpeg matcher is attached below!! 

Best regards, Markus

You can try to embed the dynamic SVGs directly into the
FO as fo:instream-foreign-object. Use aggregation or
XInclude to get the data into the pipeline.
