Here is a debugger for cases where Java applications can not be written entirely in the Java language and use the Java Native Interface (JNI) to access native code. This tools fills a gap left by traditional Java debuggers, such as the Eclipse JDT debugger, which can not satisfy all developer needs because they do not effectively support debugging native code written in languages such C/C++.
This tool will get you familiar with debugging JNI code based on a new debug interface implemented on top of the Apache Harmony JVM. This approach provides support for the seamless debugging of native methods in Java applications and access to native data. The target audience is tools developers and Java developers.
