Hello, I'm student at Hanyang UNIV. in Korea.
I study PDFbox for developing my PDF Solution.
But now, I have a problem.
I want to insert page anywhere, however PDFbox api only insert page at last.
So I try to inheritance PDDocument class.
---------------------------------------------
myPDDocument.java
...
public class myPDDocument extends PDDocument{
public myPDDocument() throws IOException {
super();
}
...
}
main.java
...
string filename = "abc.pdf"
myPDDocument document = new myPDDocument();
document = (myPDDocument) PDDocument.load(filename);
---------------------------------------------
But "org.apache.pdfbox.pdmodel.PDDocument cannot be cast to
main.myPDDocument" happen.
How do it?
PDDocument.load() is a static method and returns always an instance of
PDDocument which can't be cast to your class. There are to possible solutions
- trasnform the provided PDDocument into your class as follows:
PDDocument doc = PDDocument.load(filename);
myPDDocument myDoc = new myPDDocument(doc.getDocument());
- override the load-method too using the same idea as above
Thank you. Have a nice day!
