Following are a number of Java samples that use jPDFProcess:

SimpleMerge.java - This program will merge two PDF files into a single one.

SimplePrint.java - This program will print a PDF file to a named printer.

AddWatermark.java - This program will add a semi-transparent watermark to a document.

PDFToTIFF.java - This program converts a PDF file to a multi-page TIFF file.

FlattenFields.java - This program will "flatten" field data into the PDF content layer. This means that the field contents will become part of the PDF content and so the document will not be editable anymore.

SetPermissions.java - Encrypt the PDF document and restrict permissions.

ExportFields.java - Export field values in FDF format.

SignDocument.java - Apply a digital signature to a document. This program loads a document, then loads a digital ID from a PKCS#12 file, and then creates and signs a signature field on the first page of the document.

You can create a sample PKCS#12 file using Java's keytool program. The command line to create a test file is as follows:

keytool -genkey -keystore test.pfx -storetype pkcs12 -storepass store_pwd -keypass key_pwd -alias key_alias

ExtractText.java - Extract text content from a document.

AddBookmarks.java - Adds a bookmark for every page in a document.

AddTOC.java - Creates a table of contents at the head of the document. This sample adds a page at the top of the document and then adds a page title and a link to every page in the document.

PreflightDocument.java - Runs a preflight check on a document to see if it is PDF/X-1a:2001 compliant. jPDFProcess ships with profiles to preflight documents using the PDF/X-1a:2001, PDF/X-1a:2003, PDF/X-3:2002 and PDF/X-3:2003 standards.
