Abstract: An install factory creates install packages used to install complex applications onto multiple data processing systems in a reliable and reproducible manner. The install factory takes a variety of inputs to build a custom installation package. The custom install package may be used repeatedly for installs, using the same install package, a full install on a first data processing system, an updated install on a second data processing system, a fix or service pack on a third data processing system, and also configure an application on a fourth data processing system. Thereafter, all data processing systems have the desired level of the application installed. In addition, the install factory may create install packages that are modified in accordance with user preferences.

Abstract: Computer implemented method, system and computer program product for searching for a class in a data processing system having classloaders organized in both a classloader hierarchy and a classloader network. A computer implemented method for searching for a class in a data processing system having classloaders organized in both a classloader hierarchy and a classloader network includes receiving a request to load a class at a request receiving classloader in the classloader hierarchy. The request to load a class is forwarded to a gateway classloader in the classloader network, wherein the gateway classloader is also in the classloader hierarchy. The requested class is then searched for in the classloader network.

Abstract: A method, system, and computer program product for enabling efficient start up of an application server with the components required for complete operation of the supported application. A pre-processor autonomically determines the specific services that are required by the application to be initiated within the application server during start up of the application. The specific services are selected from a comprehensive list of available services for start up of the application server. The application server is then started up with only the specific services required by the application, rather than the full list of services.
