linux环境下Jnative使用报org.xvolks.jnative.exceptions.NativeException

[yuboy123456789]

最近做一个项目： 使用jnative调用动态库（.dll或.a文件），在windows环境下，能够完成dll动态库的调用，但是放到linux下面，改用.a文件格式的动态，jnative在linux下使用的libJNativeCpp.so已经放入/usr/lib路径下，调用时就发生异常：
org.xvolks.jnative.exceptions.NativeException: Library /opt/finger/lib/libBLServerAPI.a not found : /opt/finger/lib/libBLServerAPI.a: invalid ELF header

代码如下：
public int verifyMatch(String fingerAuth, String fingerSign, int matchResult)
throws NativeException, IllegalAccessException {
JNative Something = null;
if (Something == null) {
Something = new JNative("/opt/finger/lib/libBLServerAPI.a", "BLM_VerifyMatch");
// 利用org.xvolks.jnative.JNative 来装载 libBLServerAPI.a BLModuleServerAPI
// FNetSDK_Client.dll，并利用其BLM_OpenModule方法
Something.setRetVal(Type.INT);
// 指定返回参数的类型
}
int i = 0;
Pointer fingerAuthPointer = creatCharPointer();
Pointer fingersignPointer = creatCharPointer();
Pointer resultPointer = creatPointer();

fingerAuthPointer.setMemory(Base64.decode(fingerAuth));
fingersignPointer.setMemory(Base64.decode(fingerSign));

Something.setParameter(i++, fingerAuthPointer);
Something.setParameter(i++, fingersignPointer);
Something.setParameter(i++, resultPointer);

Something.invoke();// 调用方法

return resultPointer.getAsInt(0);
}

请哪位高手知道这是什么问题啊？
