I have pages that can be viewed as xhtml and pdf which is generated by FOP.
When I change the images, using the same image filenames, the new images
appear in the xhtml version, however the old images are shown in the pdf
version. If I use new images with different file names the new images
appear in the PDF. However as I am generating the image file names
programmatically I have to keep the old names.
It's a FOP "feature". From http://xmlgraphics.apache.org/fop/0.94/graphics.html
"FOP caches images between runs. There is one cache per FopFactory
instance. The URI is used as a key to identify images which means that
when a particular URI appears again, the image is taken from the
cache. If you have a servlet that generates a different image each
time it is called with the same URL you need to use a constantly
changing dummy parameter on the URL to avoid caching."
Like the man said, add a dummy request parameter to the URI with some
unique value e.g. a hash of the session ID and current time.
Andy.
