从Ubuntu操作系统上的java类加载共享库(JNI)时遇到问题

Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/ETcpsdk/lib/linux-x86_64/libjcryptoki.so: libcryptoki.so: cannot open shared object file: No such file or directory
    at java.lang.ClassLoader$NativeLibrary.load(Native Method)
    at java.lang.ClassLoader.loadLibrary1(ClassLoader.java:1965)

    at tutorialjni.Test.<clinit>(Test.java:7)

- Test.java

package tutorialjni;

public class Test {

    // Load an external library, called "jcryptoki"
    static {
        System.loadLibrary("jcryptoki");
    }

    public static void main(String[] args) {
        System.out.println(System.getProperty("java.library.path"));
    }

}

- LD_LIBRARY_PATH已在/ etc/environment中分配

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
JAVA_HOME="/opt/jdk1.7.0_75"
LD_LIBRARY_PATH="/opt/ETcpsdk/lib/linux-x86_64:/opt/ETcpsdk/lib/"

我拥有ETcpsdk文件夹.

• libcryptoki.so放入/opt/ETcpsdk/lib/linux-x86_64/libcryptoki.so

• 运行文件libcryptoki.so命令

  libjcryptoki.so:ELF 64位LSB共享对象,x86-64,版本1(SYSV),动态链接,未剥离

- JDK版本:

java version "1.7.0_75" …
