Here's the abstract from my JavaOne talk:
There are some situations in which it is necessary to call native code (C/C++ compiled code) from Java applications. This session describes how to do this efficiently and how to performance-tune the resulting applications.
The objectives for the session are:
- Explain reasons for using native code in Java applications
- Describe pitfalls of calling native code from Java
- Discuss performance-tuning of Java apps that use native code
I'll cover how to call native code from Java, debugging native code, and then I'll dig into performance tuning the code. The talk is not going too deep on performance tuning - focusing on the JNI specific topics; I'll do a bit more about performance tuning in my OpenWorld talk later in the day.
