Processing within a computing environment is facilitated by generating a hybrid security certificate using multiple cryptosystems. The generating includes obtaining data for inclusion in the hybrid security certificate, and generating a first digital signature associated with a first cryptosystem to cover the data, and a second digital signature associated with a second cryptosystem to cover the data. The generating further includes providing the hybrid security certificate, where the hybrid security certificate includes the data, the first digital signature associated with the first cryptosystem, and the second digital signature associated with the second cryptosystem, and where the first digital signature has no dependency on a key of the second cryptosystem or the second digital signature, and the second digital signature has no dependency on a key of the first cryptosystem or the first digital signature.

A method and apparatus for debugging applications on a microkernel without invoking services provided by a particular personality. An application debugger is separated into three distinct pieces consisting of a user interface, debug engine, debug probe (instrumentation server). The user interface supports user inputs and debugger output in a language and platform-independent syntax. The debug engine supports semantics for specific language and target operating environments. The debug probe supports low-level query, access and update of the applications's state. The instrumentation server checks to see if a requested application is in its list of known application tasks. The instrumentation server sets an application into debug mode by either attaching to the application from a list of applications that it has constructed by polling the IBM Microkernel loaders or by having the application launched by a given IBM Microkernel loader. Because the instrumentation server has root authority, it is able to enquire and obtain the application's task control port and therefore manipulate the applications's state using standard microkernel system calls.

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.

A control window for navigating and implementing menu selections in a multiple level hierarchical menu is provided having a first zone displaying a list of the selection levels and a second zone displaying a list of the selection options within a selection level. The second zone is refreshed with selections for another selection level in the menu hierarchy in response to a user implementation or registration of a selection option at the originally displayed selection level. Preset default settings in all selection levels permit the user to implement a 'fast path' hierarchical menu selection.
