It is in fact FOP (in my experience) that uses so much memory and that forms a barrier.
IIUC FOP has a Java object for almost everything on a page (if you have a paragraph on a page that contains some inline elements, this is encapsulated in a hierarchy of Java objects). Once a page is completely created and every reference is resolved, it is converted into its PDF equivalent, and the Java objects can be destroyed. If you have a lot of forward references (e.g. for page numbers in a Table Of Contents) it can take up a lot of memory, before everything is resolved. Therefore, I am not using a Table Of Contents at the moment. I am not sure if this is completely clear, but this is my experience. --------------------------------------------------------------------- Please check that your question has not already been answered in the FAQ before posting. <http://xml.apache.org/cocoon/faqs.html> To unsubscribe, e-mail: <[EMAIL PROTECTED]> For additional commands, e-mail: <[EMAIL PROTECTED]>
