[jira] Created: (PDFBOX-700) NullPointerException when trying to
merge PDFs
NullPointerException when trying to merge PDFs
----------------------------------------------
Key: PDFBOX-700
URL: https://issues.apache.org/jira/browse/PDFBOX-700
Project: PDFBox
Issue Type: Bug
Components: Utilities
Affects Versions: 1.1.0
Environment: Windows Vista 32-bit, Java 1.5.0_06, PDFBox HEAD tag (revision 937101)
Reporter: Adam Nichols
Fix For: 1.2.0
Attachments: US_Constitutional_Ammendments.pdf, US_Constitutional_Ammendments_copy.pdf
I was trying to use the PDFMergerUtility class to merge some PDFs. Using the unmodified PDFBox source, I get a NullPointerException when I call mergeDocuments(). I made two different copies of the same file to make sure it wasn't caused by something like file access. The file opens fine with Adobe Acrobat, and PDFBox can load the document with no problem, so it doesn't seem to be a corrupt PDF in this case. I'm not familiar with the PDOutlineNode class, so I'm not sure where to go from here. I will attach the PDF I'm using to this bug report. If there's anything else I can provide let me know.
Code:
public static void main(String[] args) {
String inputFile0 = "C:\\US_Constitutional_Ammendments_copy.pdf";
String inputFile1 = "C:\\US_Constitutional_Ammendments.pdf";
String outputFile = "C:\\US_Constitutional_Ammendments_output.pdf";
try {
PDFMergerUtility pdfMergerUtil = new PDFMergerUtility();
pdfMergerUtil.setDestinationFileName(outputFile);
pdfMergerUtil.addSource(inputFile0);
pdfMergerUtil.addSource(inputFile1);
pdfMergerUtil.mergeDocuments();
System.out.println("Yay, nothing went wrong.");
} catch(Exception e) {
System.out.println("Oh no, something went wrong!");
e.printStackTrace();
}
}

-------------------------------------
Sorry, two of the line numbers were off because I forgot to update my jar file after reverting my changes to PDFMergerUtility. Same result, just different line numbers.
