【问题描述】：

当我运行项目时，我的 Eclipse 安装没有任何问题，但是如果我导出与可运行的 jar 文件相同的文件，那么我会收到如下异常：

有没有人经历过这种异常。寻求帮助。

【问题讨论】：

您在项目中使用了哪些库？
JAI vendorname == null的可能重复
PS：忽略接受的答案，并查看投票最高的答案：stackoverflow.com/a/18495658/1428606。很好地解释了一切。

标签： java jar javax.imageio jai

【解决方案1】：

您能否编译下面的类并以java -cp your_runable.jar:. Check 运行它。

public class Check {
    public static void main(String[] args) {
        System.out.println(
            com.sun.media.imageioimpl.common.PackageUtil.getVendor()
        );
    }
}

输出应该类似于运行java -cp jai_imageio-1.1.jar:. Check的输出
