A high-speed content transformation method, system and apparatus. The method can include inspecting a request for transcoded content to determine input documents required to produce the requested transcoded content; determining whether the input documents have been characterized as standalone, and further determining freshness criteria for the input documents which are determined to have been characterized as standalone; locating in cache storage previously generated transcoded content corresponding to the input documents determined to have been characterized as standalone; and, serving the previously generated transcoded content in response to the request rather than generating the requested transcoded content using the input documents where the previously transcoded content meets the freshness criteria.

High-speed content transformation engine

A system and method of providing data to a mashup application may involve receiving a request from a mashup application and supplying first data to the mashup application in response to the request. Mashup information can be received from the mashup application, wherein the mashup information indicates an inclusion of the first data with second data in the execution of the mashup application. The mashup information may be stored and analyzed to identify relationships between previously unrelated data.

Identifying relevant data from unstructured feeds

The present invention is an enhanced staged event-driven architecture (SEDA) stage. The enhanced SEDA stage can include an event queue configured to enqueue a plurality of events, an event handler programmed to process events in the event queue, and a thread pool coupled to the event handler. A resource manager further can be coupled to the thread pool and the event queue. Moreover, the resource manager can be programmed to allocate additional threads to the thread pool where a number of events enqueued in the event queue exceeds a threshold value and where all threads in the thread pool are busy.

Enhanced staged event-driven architecture

Access to a session between a remote computer and an application resident at a host computer connected to the remote computer is provided via a link object embedded in a Web page accessible at the remote computer. A session is established between the remote computer and the application, and a link object associated with the established session is embedded in the Web page in response to establishment of the session. In response to termination of a session, the link object associated with the terminated session is removed from the Web page. According to another aspect, user selection of the link object associated with the established session is accepted at the remote computer. In response, a user interface to the established session, e.g., an input/output &ldquo;screen,&rdquo; is provided at the remote computer. According to another aspect, a host access web page is accessed to establish a session. A Web page is accessed from the remote computer, and a Java applet downloaded to the remote computer in response to accessing of the Web page. The Java applet is then processed, either automatically or upon a user input, to establish a session between the remote computer. The Java applet may also be processed to embed a link object associated with the established session in the Web page. According to yet another aspect, a Session Vector is maintained which identifies sessions between the remote computer and the application. A link to a session identified in the Session Vector is maintained in a Web page accessible to the remote computer. In response to establishment of a session between the remote computer and the application, an identifier for the established session is added to the Session Vector. If a session limit has been achieved, establishment of a session may be prevented.

Apparatus, methods and computer program products for managing sessions with host-based application using session vectors

Sessions with a host-based application are managed by embedding a user interface, such as a screen, for a first session between the remote computer and the application in a Web page displayed at a remote computer. Preferably, a Java applet is downloaded to the remote computer and processed to embed the user interface. The downloaded Java applet may also be processed to establish the first session between the remote computer and the application. Upon termination of the first session, the user interface is removed from the Web page. According to one aspect, a link object for accessing a second session between the remote computer and the application may be embedded in the Web page and, upon embedding the user interface for the first session in the Web page, the link object may be removed from the Web page. Upon termination of the first session, the user interface for the first session may be removed from the Web page, and the link object for the second session embedded in the Web page again. According to another aspect, the Web page is displayed in a first window, a second session established, and a user interface for the second session provided in a second window. The user interface includes a link object associated with the first session embedded therein. In response to user selection of the link object, the user is directed to the first window.

Apparatus, methods and computer program products for managing

A session is conducted with an application resident on a host computer by loading terminal information at a computer, operatively associated with the host computer and which is part of a network including a plurality of resource locations, from a host access resource location of the plurality of resource locations. The terminal emulation information is processed to conduct a session between the computer and the application. A resource location of the plurality of resource locations is then accessed from the computer while the session persists. The terminal emulation information may be downloaded to the computer from a server of the network. According to one aspect, a common environment capable of being produced under a plurality of different computer operating systems, e.g., a Java environment, is produced at the computer. The terminal emulation information is processed under the common environment to thereby conduct a session between the computer and the application. According to another aspect, the terminal emulation information is processed to instantiate a Session Object at the computer, the Session Object being configured to conduct the session between the computer and the application. A plurality of host access processing objects may be instantiated from the Session Object, the host access processing objects being configured to conduct the session between the computer and the application and having methods which are accessible to an application resident at the computer. A Session Vector which identifies the instantiated Session Object may also be instantiated.
