A method, system and program of executing an interpreted programming language application from a server at a designated virtual machine on a client computer are provided. A manifest file is extracted which indicates at least one resource for the interpreted programming language application as well as the repository file associated with the resource. The repository file is located in a web start cache and moved to a run directory accessible by the designated virtual machine, outside the web start cache. The interpreted programming language application is then executed from the run directory using the at least one resource.

Installing and updating interpreted programming language applications using a designated virtual machine

A mechanism is provided for executing an interpreted programming language application from a server at a designated virtual machine on a client computer. A manifest file is extracted which indicates at least one resource for the interpreted programming language application as well as the repository file that provides the at least one resource. The repository file is located in a web start cache and copied to a run directory accessible by the designated virtual machine, outside the web start cache. After terminating the web start application, a particular virtual machine is designated from a plurality of virtual machines based upon the run directory to which the bootstrap class copied the resource repository file thereby forming the designated virtual machine. The interpreted programming language application is then executed from the run directory using the at least one resource.

A mechanism is provided for providing a native code library from a server to an application written in an interpreted programming language for execution on a remote computer. An installer object is invoked from within a main class of the interpreted programming language application. The install object extracts a file list from the server including at least one native code library filename indicating a native code library. The native code library indicated by the native code library filename is installed to a target directory on the remote computer and the main class of the interpreted programming language application is then invoked on the remote computer. Additional native code library dependencies are also installed to the target directory on the remote computer.

Dynamically providing native libraries and their dependencies

A method of determining a number of connections to initially utilize for a download of a target data file from a set of one or more servers includes determining a maximum number of initial connections based at least in part upon a number of servers available to serve a target data file to be downloaded, determining a size of the target data file, and determining the number of initial connections to utilize for a download of the target data file. The later determination is based at least in part upon the maximum number of initial connections, the size of the target data file, and a chunk size of one or more chunks into which the target data file is to be decomposed.
