JExpress is a Java installer builder and auto-updater. It gives you your choice of a standalone installer, including both native and cross platform installers and updaters for Windows, Mac OS X, Linux, and Solaris, or a Java Web Start one-click install. You create your installer quickly with your choice of a simple wizard or a powerful advanced interface, both included. You can bundle the exact JVM you want with your installer. The auto-updater gives you a continuous revenue stream after the sale. Your software is always up-to-date, so your customers have fewer problems. You also get all the features you expect in a top end installer. Your Java application becomes a native program just like any other. On Windows it's an EXE, on Mac OS X an app bundle, etc. If you need something really special, you can customize your installer by adding simple Java classes. You can even get a source license at a reasonable price.
OpenXava is a framework to develop AJAX JavaEE/J2EE applications rapidly and easily. It allows you to define applications only with POJOs, JPA, and Java 5 annotations. It is feature rich and flexible. It generates JSR-168 portlet applications (Liferay, WebSphere Portal, Jetspeed, etc.).
jPDFWriter is a Java class library to create PDF documents directly from Java programs without having to install any third party drivers or software. It emulates the standard Java classes to print and draw graphics to reduce the learning curve when using the library and reuse existing code. It can create PDF files in two ways: PDF files can be created directly using jPDFWriter's very simple API (simply create a PDFDocument object, create as many PDFPage objects as necessary, draw strings, graphics, or any other elements supported by Graphics2D to the pages, and save the document), or jPDFWriter can extend the standard Java PrinterJob to create PDF files as though printing to a physical printer. This allows reuse of existing printing code and lets an application decide, at runtime, whether to send the output to a printer or to a PDF file. PDF files can be saved to files on a disk, written to a java.io.OutputStream, or written directly to a javax.servlet.ServletOutputStream to show in a browser when working within a J2EE application server. jPDFWriter is written entirely in Java, so application portability and operating system independence are not compromised.
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. The library has a simple interface to work with PDF documents and is designed to be integrated easily and seamlessly into your PDF document workflow. jPDFProcess provides the functionality found in many other Qoppa Software libraries, including printing, setting permissions and security, creating and assembling documents, digital signing, working with form fields, extracting text, and more. 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.
