Abstract: A method of implementing in a general purpose computer system, a remote procedure call between an application and a target application is described. The target application is one of a plurality of second applications. The first application generates a first message, the first message having a message body and a thread ID of the target application. The first application writes the first message to a shared memory. The target application to polls the shared memory, and reads the first message from the shared memory. The target application generates a second message, the second message having a message body and a thread ID of the target application. The target application writes the second message to the shared memory. The first application polls the shared memory and reads the second message from the shared memory. The first message may be sent in response to the second message, vice versa, or asynchronously.

Abstract: 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.

Abstract: Method and apparatus are disclosed for the intensive use of garbage collection in order to determine the exact amount of memory that is consumed by a running application at any point of its execution. A garbage collector executes immediately prior to allocations of memory during execution of a program. The amount of memory used by the application is known after each such allocation of memory, and is very close to or equal to its theoretical requirement. A developer is also enabled to determine whether a specified memory allotment for an application is ever exceeded.

Abstract: Method and apparatus are disclosed for the intensive use of garbage collection in order to determine the maximum amount of memory that is consumed by a running application. A system garbage collector executes between designated pairs of program instructions or statements. The amount of memory used by the application is known after each designated program instruction or statement, and is equal to its theoretical requirement. A developer is able to determine whether a specified memory allotment for an application is ever exceeded.
