关于jar包运行提示错误的问题

Question

我在cmd上运行刚刚导出的jar包 ，程序是java写的一个桌面软件，但是出现错误如下：
D:>java -jar work_space.jar
Error: A JNI error has occurred, please check your installation and try again

已经在网络上尝试删除DSA、RSA、SF等文件，但是一直出现如上的提示，以为是自己的导出方式有问题，但是使用其他程序的jar文件运行则可以正常运行，怀疑是否是和使用了数据库有关，求大神帮忙

Answer 1

是你自己导出来的jar文件吗? 是不是使用了数字签名?
