"org.apache.jasper.JasperException" 在码头访问 JSP 时

Question

我正在尝试运行一个在 Jetty 中带有 JSPs 的网络应用程序。我为 JSP 支持添加了以下依赖项。

1)javax.servlet.jsp-2.2.0.v201112011158.jar
2)org.apache.jasper.glassfish-2.2.2.v201112011158.jar
3)javax.el-api-3.0.0.jar@star
4)javax.el-2.2.0.v201303151357.jar
5)org.eclipse.jetty.orbit.org.eclipse.jdt.core-3.8.2.v20130121.jar

然而，在访问 JSP 之一时，我遇到了以下异常：

HTTP ERROR 500

Problem accessing /ui/servletcontext.jsp. Reason:

我已经查看了很多论坛以查看问题出在哪里，但找不到任何答案。请帮忙。

在嵌入式 Jetty 中设置 JSP 需要的步骤比仅将类添加到类路径要多得多。

JSP 环境也需要设置/配置。
