I didn't say you can't use tables spanning multiple
pages. I said, if you are running into problems with
memory consumption, this could be one cause (out of
many possible others).
The standard procedure when you are getting
OutOfMemoryExceptions is:
1. Look for a bigger machine, and increase JVM memory
settings (they should not exceed physical memory). This
will only go so far.
2. If you are running a servlet, serialize requests for
PDF rendering.
3. Get rid of forward references. This is often a really
big win.
4. If you have some amount of large graphics which is
scaled down by FOP anyway, scale them down before you
feed them to FOP. This helps especially if you have
inncently looking highly compressed but high-resolution
JPGs (something in the 1000x1000 pixel range, one such
critter can eat up to 5MByte).
5. If everything above is already stretched to the
limit, simplify your layoput and the intermediate FO
structure. However, unless your whole document is a
single table, this is often small change. Nevertheless,
some small modifications in the style sheet can make
a difference between working and not working.
