I don't have much time to answer (catching a flight), but I can tell you that the example in the white paper is somewhat outdated. However, if you look at the download page of the examples, you can find an example that will replace the PreSign and PostSign code: http://sourceforge.net/p/itext/code/5969/tree/tutorial/signatures/src/main/java/signatures/chapter4/C4_09_DeferredSigning.java The idea is to prepare the document for signing by creating an invalid signature consisting of <0000...00> first in the method emptySignature() and then afterwards replace the <0000..00> by a correct signature in the method createSignature(). Hope this helps.
