A method and system for running a Java ME application on a computer system are described. The Java ME application is a software program designed for execution on a resource-constrained platform. A first virtual machine is launched in a process, the first virtual machine being is caused to run an application emulator. A second virtual machine is launched in the process, the second virtual machine being caused to run the Java ME application. The application emulator interfaces with application programming interfaces of the second virtual machine to interface with inputs and outputs of the Java ME application and redirect the inputs and outputs to local devices controlled by the application emulator.
