jPDFSecure is optimized for performance and is built on top of Qoppa's proprietary PDF technology so there is no need for any third party software or drivers.
jPDFSecure has a simple interface to load PDF documents from files, network drives,URLs and even input streams, which can be generated runtime or come directly from a database. After changing security settings, jPDFSecurity can save the document to a file, a java.io.OutputStream or a javax.servlet.ServletOutputStream when running in a J2EE application server to output the file directly to a browser.
jPDFSecure is a Java library that can be used by developers in their Java application. If you are looking for an end-user application to manipulate PDF documents, please take a look at PDF Studio.
jPDFSecure is platform independent and can be used in any environment that supports Java, including Windows, Mac OSX and Linux.
