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.

You also need fontbox and commons-log, as described on the dependency page. Alternatively, you can use pdfbox-app, which has all needed for merging.
