Java-应用日志错误
Java-application log error
将我的 EAR 文件部署到服务器后出现以下错误。
由于我是 JAVA 的新手，我无法弄清楚可以解决此问题的方法。
非常感谢任何帮助。
我也尝试过更改编译器版本，但这似乎也无济于事。
另外，错误如下。

您的 class 是针对比您的服务器 运行 更高的 Java 版本编译的。 Java 6 上的 WebSphere 7.0 和 8.0（和 8.5，开箱即用）运行，所以我猜你的 class 是用 Java 7 或更高版本编译的。 Java 向后兼容但不向前兼容 - 您不能 运行 较新规范 class 在较旧规范的 JVM 上使用。
最简单的解决方案是使用 Java 6 重新编译您的 classes。或者，如果您 运行ning WebSphere 8.5.5，您可以将服务器切换到 运行 在 Java 8 上使用 WebSphere 的 bin 目录中的 "managesdk" 脚本（假设您在服务器上安装了 Java 8 包）。
我认为问题在于服务器运行的 Java 版本早于您编译的版本。
E.G 用 java7 编译，服务器在 java6
上运行
