I'm using eclipse. This is what I want. I created a new Java application
project (say TestPDFBox) with a main class with following code.
PDDocument document = new PDDocument();PDPage blankPage = new
PDPage();document.addPage( blankPage
);document.save("BlankPage.pdf");document.close();
Then I need to add those jar files generated in target folder of PDFBox to
build path of my new project (I did build the PDFBox project from source).
That is what I did. But let's say I need to check the functionality of
document.save("") method. But I don't have a reference to it's sources
because I directly used generated jars. As Tilman said I built PDFBox from
sources but I don't know a proper way to use it other projects other than
adding those jar files to build path.
