"Contributed and administered by ICEsoft Technologies Inc., ICEpdf.org is a place where enterprise Java developers can learn, share, and contribute information and ideas to a growing community of ICEpdf developers. ICEpdf is an open source Java PDF engine that can render, convert, or extract PDF content within any Java application or on a Web server. ICEpdf.org provides a range of development and support resources to benefit all ICEpdf developers. Source code and application reference implementations are available for download here. Numerous reference implementations and examples are available to enable rapid learning and successful use of the product. The reference implementations are commercial quality implementations that can be deployed as-is, customized to meet specific requirements, or used as learning aids on how to use various features. Visit the ICEpdf demos page to see ICEpdf in action and to evaluate the capabilities of ICEpdf as a Java PDF viewer or deployed as servlet a headless server engine. Remember that ICEpdf is completely customizable and and can be completely embedded in your Java application. We invite you to join the ICEpdf community and to participate in the user forums. The resources available here and on the ICEpdf forums will get you up and developing that much quicker. "

"Apache Tuscany simplifies the task of developing SOA solutions by providing a comprehensive infrastructure for SOA development and management that is based on Service Component Architecture (SCA) standard. With SCA as it's foundation, Tuscany offers solution developers the following advantages: Provides a model for creating composite applications by defining the services in the fabric and their relationships with one another. The services can be implemented in any technology. Enables service developers to create reusable services that only contain business logic. Protocols are pushed out of business logic and are handled through pluggable bindings. This lowers development cost. Applications can easily adapt to infrastructure changes without recoding since protocols are handled via pluggable bindings and quality of services (transaction, security) are handled declaratively. Existing applications can work with new SCA compositions. This allows for incremental growth towards a more flexible architecture, outsourcing or providing services to others. In addition, Tuscany is integrated with various technologies and offers: a wide range of bindings (pluggable protocols) various component types including and not limited to Java, C++, BPEL, Spring and scripting an end to end service and data solution which includes support for Jaxb and SDO a lightweight runtime that works standalone or with other application servers a modular architecture that makes it easy to integrate with different technologies and to extend Integration with web20 technologies Apache Tuscany SCA is implemented in Java and C++ (referred to as Native)"

"OpenXava is a tool for Rapid Java Web Development, well-suited for business and database oriented applications. Write simple domain classes with Java or Groovy, and get an AJAX application ready for production. Since v4.2 OpenXava also produces iPad Web applications that behaves and looks like iPad native applications."

"The PHP/Java Bridge is an implementation of a streaming, XML-based network protocol, which can be used to connect a native script engine, for example PHP, Scheme or Python, with a Java virtual machine. It is up to 50 times faster than local RPC via SOAP, requires less resources on the web-server side. It is faster and more reliable than direct communication via the Java Native Interface, and it requires no additional components to invoke Java procedures from PHP or PHP procedures from Java. "

"The XMPP Standards Foundation is an independent, nonprofit standards development organization whose primary mission is to define open protocols for presence, instant messaging, and real-time communication and collaboration on top of the IETF's Extensible Messaging and Presence Protocol (XMPP).
