I'm attempting to use the Apache PDFMergerUtility, following one of the many online examples. My problem is I get an NoClassDefFoundError exception while creating an instance: PDFMergerUtility pdfMerger = new PDFMergerUtility();
Here's my import: import org.apache.pdfbox.multipdf.PDFMergerUtility;
I downloaded the jar file pdfbox-2.0.15.jar and put in my Netbeans Project libraries.
What might be the cause?
I've read the Apache documentation, and looked at numerous examples that show the exact code.
