This Java program merges two PDF files into a single one using Qoppa’s PDF library jPDFProcess.

// Load the two documents
PDFDocument pdfDoc1 = new PDFDocument ("input1.pdf", null);
PDFDocument pdfDoc2 = new PDFDocument ("input2.pdf", null);
// Append the second document to the first one
// Save the merged document
pdfDoc1.saveDocument ("output.pdf");

jPDFProcess is a PDF library that provides a lot of PDF functions to work with PDF documents. If you’re only merging and splitting PDF documents, our PDF library jPDFAssemble may satisfy your needs.
