3 cp your libxxx.so into the java.library.path. Java 一般使用两个path：classpath 和 java.library.path. Java.library.path是 非java类包 的位置如（dll,so） 解决办法： 第一种方法，在代码里设置环境变量. 第二种方法：执行时 在vm arguments里添加-Djava.library.path. I am trying to make a connection to oracle through java program using OCI driver. Following is the configuration. Windows 7, 32 bit. JDK 1.7; Oracle client 11g R2. Ojdbc7.jar in the class path of my standalone application. But I am getting following exception: Exception in thread 'main' java.lang.UnsatisfiedLinkError: no ocijdbc12 in java. 在用exe4j打包java工程后，在其他电脑运行结果出现了java.lang.UnsatisfiedLinkError：no in java.library.path的错误，刚开始以为是jar包没在classpath路径中，后来才发现java.library.path与classpath是两个不同的变量，后者是我们所熟知的类路径，与jar包有关；而前者与dll有关，它指定dll文件搜.

其中涉及的测试源码如下：

For those who didn't install Java with default settings, a systematic way for solving JNI class path problem is:
1> include 'System.out.println(System.getProperty('Java.library.path')); ' in your 'static' block, right before loading the class.
2> run your program and not surprisingly you got the err again, but this time with java.library.path info for your system. (it's important since this path name varies among systems).
3> cp your libxxx.so into the java.library.path

Java一般使用两个path：classpath 和 java.library.path

classpath是指向jar包的位置

java.library.path是非java类包的位置如（dll,so）

解决办法：

第一种方法，在代码里设置环境变量

第二种方法：执行时在vm arguments里添加-Djava.library.path= /usr/local/lib，例如java -Djava.library.path=. xxx（xxx是某个类文件的名字，不包括后缀）

第三种方法：设置环境变量java.library.path

1：Linux下的系统变量LD_LIBRARY_PATH来添加java.library.path

2：Windows下设置哪个环境变量???????????????????

如果你上面看不懂的话就继续向下面看：
1、 在你载入jni类之前 放入“System.out.println( System.getProperty('java.library.path'));
2、运行你的程序你将获得java.library.path指向的目录
3、拷贝你的libxxx.so到java.library.path指向的某个目录下面。
注意：
Linux下：一定要将Linux下的共享库（我暂且这么叫:）命名成libxxx.so的形式，'xxx'是你在System.loadLibrary('xxx')中用到的加载库名称。

Windows下：一定要将Windows下的共享库（我暂且这么叫:）命名成xxx.dll的形式（没有前边的lib三个字母），'xxx'是你在System.loadLibrary('xxx')中用到的加载库名称。

查了其他的资料：
也可以通过设置LINUX下的系统变量LD_LIBRARY_PATH来添加java.library.path，只要在启动~/.bashrc中添加如下代码然后重新登录shell，就可以将动态库放在当前目录下运行你的jni程序了。
export LD_LIBRARY_PATH=.:.:$LD_LIBRARY_PATH

另外也可以通过如下I'm new to JNI. I see there are several ways to set JVM to look for libraries dll, so, etc.

No Ocijdbc18 In Java Library Path Macbook Pro

The following are the system requirements for installing the JDK and the JRE on macOS:

No Ocijdbc18 In Java Library Path Macbook

• Any Intel-based computer running macOS.

• Administrator privileges.

  You cannot install Java for a single user. Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK and JRE on macOS.

• When you install the JDK, it also installs the JRE. However, the system will not replace the current JRE with a lower version.

  To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.

• When you install the JRE, you can install only one JRE on your system at a time. The system will not install a JRE that has an earlier version than the current version.

  To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. /glarysoft-free-activation-code.html. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.

  Note:

  Installing a JRE from Oracle will not update java -version symlinks or add java to your path. To do this, you must install the JDK.
