A system and a method for minimizing the functionality-gap between Java and native platforms while keeping the impact on each Java API static footprint as small as possible. A Java Runtime Dynamic Invocation API is used for low-level bridging between Java and C/C++, enabling the dynamic invocation of native C/C++ functions and C++ class/object methods from the Java side without adding any additional ad hoc implemented native code to the overall Java component implementation. Thereby, the need to write new native code when implementing a Java component that needs to invoke some native functionality is reduced.
