servlets - @WebServlet 在 GlassFish 5 + JDK 13 中失败并出现 java.lang.RuntimeException: com.example.NewServlet。(NewServlet.java:1)，总是在第 1 行
问题描述
JSP 和 html 文件由 NetBeans 中的 Glassfish 服务器提供，但不是 servlet。最新的 NetBeans 配置为使用 JDK 最新 13，Glassfish 使用的是 Java EE 1.8
浏览器报错：
HTTP Status 500 - Internal Server Error

解决方案
假设“ Latest NetBeans ”指的是 NetBeans 11.2，Glassfish 问题是由使用 JDK 13 运行 NetBeans 引起的。这种方法没有直接的问题；从 NetBeans 11.2 开始明确支持它。
但是，这意味着当您在 NetBeans 中启动 Glassfish 5 服务器时，它也将使用 Java 13。请参阅 NetBeans 错误报告NETBEANS-2256 NetBeans 11 vc3: Unable to manage GlassFish 5.1 when running NetBeans using any JDK 8 以上说明：
如果我使用 JDK 9+ 运行 Apache NetBeans，则无法从 IDE 中管理 GlassFish 服务器或部署到 GlassFish 服务器。 GlassFish 5+ 目前仅支持 JDK 8 ...
此问题不仅限于 NetBeans IDE。例如，请参阅Eclipse Glassfish/Payara 无法识别我的 JDK。
您的选择是：
- 编辑netbeans.conf以使 JDK 8 成为 NetBeans 11.x 的默认 Java 版本。有关如何执行此操作的详细信息，请参阅此 SO 答案。请注意，这不会阻止您在 NetBeans 中为您的项目添加 JDK 13 作为第二个 Java 平台（使用Tools > Java Platforms > Add Platform...）。如果您这样做，请确保您的 JDK 8 更新版本与您的 Glassfish 5.x 版本兼容，如这个有用的 SO 答案中所述。
- 使用 JDK 13 时，请在 NetBeans 11.2 中使用替代应用程序服务器。例如Wildfly 18+ 支持使用 JDK 13。
