Utilizing Java Native Interface (JNI) Support

數據庫Oracle 10.2.0.3.0 用的jdk版本為1.4.2_08, 低了一點.

有一個功能不好實現, 開始計劃用C 寫好, 用JNI在java中調用.
本機測試成功, 裝入Database後呼叫失敗.
google了一下,原來是Oracle 不支持.

3.2.2 Utilizing Java Native Interface (JNI) Support

The Java Native Interface (JNI) is a standard programming interface for writing Java native methods and embedding the JVM into native applications. The primary goal of JNI is to provide binary compatibility of Java applications that use platform-specific native libraries.

Oracle Database does not support the use of JNI in Java applications. If you use JNI, then your application is not 100 percent pure Java and the native methods require porting between platforms. Native methods can cause server failure, violate security, and corrupt data.
