基于JNI技术C++测井应用程序集成方法

Integration of the C++ well logging application based on JNI technology

一体化网络测井处理解释平台是一个采用Java语言开发的全新的跨平台的大型综合测井处理解释系统,向前兼容、最大限度将不同方式及不同编程语言的应用程序无缝集成、进而实现资源共享,不仅体现平台可扩充性和兼容性的设计特点,也是决定平台顺利推广的重要功能之一。在平台集成的应用程序中,利用C++编写的应用程序占主要部分。通过大量测试以及对本地化接口(JNI)技术的研究,建立了一套C++应用程序集成模式,将平台绘图、数据与C++应用程序有机结合,实现了平台对C++语言应用程序的无缝集成。利用此集成模式及方法避免了重复编码,缩短了模块开发时间,提高了平台应用模块开发速度,通过实际应用,满足现场应用要求。

The integrated network well-log processing and interpretation platform is a novel cross-platform large-scale comprehensive well-log analysis system developed on the basis of Java Language,which is characterized by perfect compatibility with former programs based on Java or any other language,enabling a seamless integration of various programs and sharing resources in a wide scale.Such characteristics are significantly incarnated not only by the designed concept of expansibility and compatibility but also by a future trend of the application and popularization for this system.The C＋＋ language was employed for a major part of the integration programs of the platform.Through extensive laboratory tests and in-depth studies on the JNI technology,an integration mode based on C＋＋ was established,which enabled C＋＋ programs to combine closely with drawing and data from the platform,achieving a seamless integration of the platform with C＋＋ programs.Field tests indicated that this integration mode avoided rewriting codes,shortened the period of module development,dramatically reduced RD expenses,and considerably met the practical need of field applications.
