Computer program code and method for delivering external data to a process running on a virtual machine
A method and system for delivering external data to a process running on a virtual machine, the virtual machine running on an operating system. The method includes the steps of executing instructions on the virtual machine that obtain state data related to the process; querying the virtual machine to obtain component data related to the state data; and manipulating the component data to deliver the external data to the process. In one example, the system provides a single sign-on application that passes user credentials to a Java applet running on a Java virtual machine.
1. A non-transitory computer readable medium containing computer software that retrieves and manipulates attribute information of a target process executed by a virtual machine, the software comprising:
executable code that determines whether an interface window has been opened by the target process;
executable code that hooks into a first application program that is executing the virtual machine to retrieve the attribute information from the target process, if the window is determined to have been opened;
executable code that determines a communication address based on an operating system identifier that corresponds to the target process;
executable code that communicates the attribute information that uniquely identifies the target process;
executable code that parses the received attribute information to obtain a window identifier of the target process;
executable code that determines which of a plurality of windows has a window identifier corresponding to that of the target process;
executable code that generates a component tree for the window determined to have a window identifier matching that of the target process using the received attribute information; and
executable code that provides communication access with the target process using the generated component tree.
2. The non-transitory computer readable medium of claim 1 , wherein a second application program, executing outside the virtual machine, is provided with communication access with the target process and wherein the second application program is a single-sign-on application that cooperates with the target process to authenticate a user's access to the target process.
3. The non-transitory computer readable medium of claim 1 , wherein a second application program, executing outside the virtual machine, is provided with communication access with the target process and wherein the second application program tests processes executing on the virtual machine.
4. The non-transitory computer readable medium of claim 1 , wherein the virtual machine is a Java virtual machine.
