How can I invoke Java functions from my C application?

Invoking Java Functions from C

While executing Java functions from the command line is an option, there are alternative methods for calling these functions directly from a C application.

One approach involves leveraging the Java Virtual Machine (JVM) creation process. Detailed steps can be found in the resource "Creating a JVM from C", which demonstrates the procedure for establishing a JVM and initiating a method invocation.

In scenarios where the JVM is already established, such as when your C program is triggered by a Java program, a viable strategy is to cache the JNIEnv* pointer. However, it's crucial to exercise caution when caching pointers to the JVM from C/C due to certain underlying semantics. For more information on this subject, refer to the JNI reference.
