Hi,
When opening a PDF file, if the PDF file is corrupted, an exception is thrown
and but the file handle seems not to be closed properly. I cannot delete the
file after that. Is it a bug ? Any suggestion ?
I'm using Java 1.6, Windows 7, iText 5.4.0.
Here the trace:
2013-05-09 23:33:07,702 ERROR [IncomingDocUtil:106] Error
com.itextpdf.text.exceptions.InvalidPdfException: PDF header signature not
found.
at com.itextpdf.text.pdf.PRTokeniser.getHeaderOffset(PRTokeniser.java:214)
at com.itextpdf.text.pdf.PdfReader.getOffsetTokeniser(PdfReader.java:387)

at com.itextpdf.text.pdf.PdfReader.<init>(PdfReader.java:190)
at com.itextpdf.text.pdf.PdfReader.<init>(PdfReader.java:180)
Code:
public static int getNumOfPages(String filePath) {
int numOfPages = 0;
PdfReader reader = null;
try {
reader = new PdfReader(filePath);
numOfPages = reader.getNumberOfPages();
} catch (Exception e) {
MiscUtils.getLogger().error("Error", e);
} finally {
if (reader != null) {
reader.close();
}
}
return numOfPages;
}
Thanks,
Tan
