Unfortunately you did not provide more details regarding your test scenario and environment.
A typical reason of blank pages is a binary data corruption (by an implicit applying of character encoding conversion to a binary document) by a saving or sending a PDF to HTTP. For example:
pdf-generation-troubleshooting-f4/pdf-pages-are-all-blank-t680.html
If it is definitely not your case, please publish the HTML, PDF samples and Java code you run.
