Now the use of PDF documents has become more and more common, it is in the document compression, security and so on, the performance is very good, about its benefits I do not say here more. So how do you use the Java language Development application to output documents in PDF format? Here to introduce Itext, it is a source code development project, you can use it
There is also a project for creating a PDF file----iText.
PDFBox has two subprojects below: Fontbox is a Java class library that handles PDF fonts; Jempbox is a Java class library that handles XMP metadata.
