Are you sure? The proxy/client is getting only a PDF document
(MIME type application/pdf), no JPEGs. The JPEGs are incorporated
within the PDF documents. Nothing is sent to the proxy/client
until the PDF document is finished (would have to be, if only to
solve the "Page 1 of XXX" resolution issues.) I would think the
proxy/client would be completely oblivious to the fact that the PDF
contains JPEGs within it when it receives the application/pdf stream.
No problem whatsoever with the rest of what you're saying, just
this premise.

Heh... no, I'm not sure. That's what I understood the OP to mean when
I read:
My problem is that the servlets which builds the
dynamic charts are called for the first time only. On the
subsequent calls the
old charts are only built in PDF and the servlets are not getting
called.
I take this to mean that since FOP does not see a change in the URL/
servlet call generating the fo:external-graphic element, it uses a
'cached' version. I suspect that unless the call is modified--at
least slightly--using a technique similar to what Jeremias described,
FOP will continue to think that there is no need to call the servlet
again, thereby causing the 'old' chart to be used.
Of course, it would help if vijay visu (the OP) would clarify this
point.
