启动jetty后，访问jsp页面报500错： JSP support not configured

问题：启动jetty后，访问jsp页面，出现一下错误：

HTTP ERROR: 500

JSP support not configured

RequestURI=/capaa/WEB-INF/jsp/error/500.jsp

Powered by Jetty://

原因：是应为没有加载jetty用来解释jsp的jar包。加载进来就可以了。

对应需添加 MAVEN 依赖：

<dependency>

<groupId>org.eclipse.jetty</groupId>

<artifactId>jetty-jsp-2.1</artifactId>

<version>7.2.2.v20101205</version>

</dependency>

<dependency>

<groupId>org.mortbay.jetty</groupId>

<artifactId>jsp-2.1-glassfish</artifactId>

<version>2.1.v20100127</version>

</dependency>

========原来已包含的依赖：

<dependency>

<groupId>org.eclipse.jetty.aggregate</groupId>

<artifactId>jetty-all</artifactId>

<version>8.1.8.v20121106</version>

</dependency>

<dependency>

<groupId>org.eclipse.jetty</groupId>

<artifactId>jetty-webapp</artifactId>

<version>8.1.8.v20121106</version>

</dependency>
