JNAbagator用于生成Java JNA包装器的SimpleMeaningfulExample无法工作

我尝试了JNAvior SimpleMeaningFule示例 和 得到：

…在Mac OS X 10.5.8和Ubuntu 8.04上，都运行Java 1.5.0_20

我在Mac OS X上切换到1.6.0_15并再次尝试，得到：

我做错什么了吗

更新：我发布了我的问题来查看这个帖子：并收到了来自JNB项目所有者Olivier Chafik的回复。总结如下：

我在JNOR中发现了一个回归 他上传了一个固定的快照构建： 该构建工作得更好，但没有生成TestLibrary.java 我提交了一份bug报告：

---

更新2:Olivier在意识到缺少TestLibrary.java不是一个bug之后，因为默认情况下它嵌入在生成的Test.jar文件中。

好吧，你自己已经解决了这个问题。版本问题

消息告诉您，您的JRE不知道如何执行jar中的类，因为jar中的类的版本比JRE本身更新

jar文件可能是用Java1.6.x编译的。因此，当您尝试执行它时，JRE会抱怨UnsupportedClassVersionError：错误的版本号，因为JRE的版本低于编译源代码的JDK版本。JRE 1.5无法读取jar中类的较新类文件版本

---

当您切换到Java 1.6.015时，用于编译jar文件的JDK的主要Java版本和用于运行jar的JRE版本都是相同的1.6.x，并且运行良好。

我自己解决了一半问题。在我切换到Java 1.6.0_15之后，JNB失败，出现NullPointerException。我希望有人知道为什么。错过了。只是跳过了阅读整个第二次输出粘贴。由于它看起来运行正常，我自己解决了一半的问题。在我切换到Java 1.6.0_15之后，JNB失败，出现NullPointerException。我希望有人知道为什么。错过了。只是跳过了阅读整个第二次输出粘贴。因为它看起来运行正常
