jPDFSecure is a Java library which can digitally sign PDF documents and change security settings on PDF Documents. With jPDFSecure, your application or Java applet can encrypt PDF documents, set permissions and passwords, and create and apply digital signatures. 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 at runtime or come directly from a database. After changing security settings, jPDFSecure 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 platform-independent and can be used in any environment which supports Java.
jPDFImages is a Java library to export images from PDF files and import images into PDF files. It can create images from pages in a PDF document and export them as JPEG, TIFF, or PNG images. It can return the image of any page in the document to the host Java application as a BufferedImage for further processing or to save in different formats. It can create documents or add pages to existing documents by importing TIFF, JPEG, and PNG images. After creating or modifying a document, it can save to the local filesystem or to an output stream to be able to serve the document directly to a client browser when working within a J2EE server. jPDFImages 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.
jPDFFields is a Java library for working with interactive PDF forms in both AcroForm and XFA formats. It allows your application to get and set field values, and can import and export to the FDF, XFDF, and XDP formats. It can also "flatten" fields in a document. (Flattening is the process of merging the fields into the PDF content layer so the information is retained, but as static PDF content.) jPDFFields is built on top of Qoppa's proprietary PDF technology, so it is 100% Java and does not require any third party software or drivers.
RSyntaxTextArea is a syntax highlighting, code folding text editor. It has support for over 30 programming languages and is completely customizable. By extending JTextComponent, it easily integrates into any Swing application and provides an easy way to add syntax highlighting to a program.
Jelix is a PHP5 framework which helps you to develop any kind of Web application. It is designed to provide high performance on heavily-loaded Web sites.
