jPDFAssemble is a Java library to assemble PDF files. It can combine, merge, or split PDF documents, and allows the addition or manipulation of bookmarks. It can save resulting documents to the local filesystem or to an output stream, to be able to serve the documents directly to a client browser when working within a J2EE server. jPDFAssemble is built on top of Qoppa's proprietary PDF technology, so you do not have to install any third party software or drivers. It is also 100% Java, so it is completely platform-independent.
jPDFProcess is a Java library to work with PDF documents which can be used to deliver customized PDF content to your users or to process and manipulate incoming PDF content.

It can work with PDF documents from files, URLs, and input streams, and can save documents to files and output streams, so it can serve documents from a J2EE application directly to a client browser without any temporary files. jPDFProcess is platform-independent, and can be used in any environment which supports Java.
