Abstract: A system for performing ‘server-push” of information from a server to a client machine for a Java Servlet based web application via a request/response communication cycle includes an application server having a Java Servlet Engine for running the Java Servlet based web application, a push Servlet and a push Application Program Interface (API). The push Servlet maintains open a network connection from the server to the client machine and the Java Servlet based web application calls the push API to push information from the server to the client machine.

Abstract: A stateful method of processing an XML markup document within a distributed computing system, includes the steps of: receiving the XML markup document by the CRE, parsing and holding the XML document's state by the CRE, receiving XML commands by the CRE, performing operations comprised in the XML commands upon the XML document by the CRE, and then updating the XML markup document's state by the CRE.

Abstract: A network-based computing system that automates, simplifies, and optimizes the compilation, deployment, and execution of an application by any type of a client machine connected to a server via any type of a network connection. The system includes a client runtime environment, a server runtime environment and an object-oriented markup-business logic binding mechanism. The client runtime environment manages client side code and screen definitions. The server runtime environment dynamical compiles code to ensure client platform compatibility. The system delivers network applications on demand, by separating them into lightweight modules and delivering these modules.

Abstract: A computing system for performing stateful distributed computing includes a client machine having a Client Runtime Environment (CRE) that is adapted to maintain the state of an application in the client machine. The CRE maintains state of the application by first retrieving a first markup document of the application, creating and storing a first object oriented representation of information contained in the first markup document. The first object oriented representation defines a first state of the application. Next, retrieving a second markup document, creating and storing a second object oriented representation of information contained in the second markup document. Finally merging the first and second object oriented representations thereby forming a new object oriented representation of information contained in the first or the second markup documents. This new object oriented representation defines a new state of said application.
