Abstract
Abstract A method for debugging a target application comprising Java code having native method dll's associated therewith. The method is carried out in a computer having an operating system, a system debug application programming interface (API), and a Java virtual machine having a Java debug API. According to the method, the Java virtual machine is first launched under the system debug API. The application is then run under the Java virtual machine. Because the Java virtual machine that runs the target application itself runs under the system debug API, simultaneous control of the target application via the system debug API and the Java debug API is enabled. Thus, the method effects the debug of the target application by simultaneously debugging the Java code and the native method dynamic load libraries.
