When I tried to process two 1.6G pdf file, an error occured:
java.io.IOException: Not enough storage is available to process this command
at sun.nio.ch.FileChannelImpl.map0(Native Method)

at com.lowagie.text.pdf.PdfReader.<init>(PdfReader.java:145)
at sticker.Main.main(Main.java:60)
it means that the error occured at :
reader = new PdfReader(new RandomAccessFileOrArray(fileList[docNum]),
null);
however, in the book "ITEXT in action" said: using new
RandomAccessFileOrArray(fileList[docNum])
in the pdfreader constructor will partial read the original file, I'm
confusing.
if the error occurs in the pdfReader constructor, it will be still no useful
to rewrite the pdfcopy class or
the pdfwriter class.
cheers,
