Java 错误的ELF类：ELF类32（可能原因：体系结构字宽不匹配）

我有一个奇怪的异常，说ELF类错误，但包装器设置正确

要使用此SDK从比利时身份证发行人官方网站读取比利时身份证，请执行以下操作：

代码：

它不起作用，因为您使用的是64位版本的Java，并且您尝试使用的SDK包含一个32位本机库（

libbeidlibJava\u Wrapper.so.3.5.3

）。64位JRE无法加载32位本机库

---

您需要使用32位版本的Java，或者查找具有64位本机库的SDK版本。

谢谢。这意味着在同一台PC上，我必须运行双Java，一个是64位，另一个是手动运行32位。因为我的其他应用程序运行在同一台PC上，这台PC只设计用于64位java。只有此模块需要32位，并且它们没有64位库。
