Index

Calling Java back from native code

In the previous chapter, we discovered how to get a Java class descriptor with the JNI method FindClass(). However, we can get much more! Actually, if you are a regular Java developer, this should remind you of something: the Java Reflection API. JNI is similar in that it can modify Java object fields, run Java methods, and access static members, but from native code!

For this last part with the Store project, let's enhance our store application so that it notifies Java when an entry has been successfully inserted.

Note

The resulting project is provided with this book under the name Store_Part10.
