应用场景：
java
项目架构: Emmbed Jetty + Spring + JSP+Maven。web
项目经过maven-shade-plugin插件打为jar包，经过命令：“java -jar xxx.jar” 方式运行。
spring
注意：服务器端安装JRE环境，而非JDK。若是安装JDK则访问正常！！！
apache
Maven JSP配置：服务器
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-jsp</artifactId>
<version>8.1.4.v20120524</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>session
访问页面，报错：架构

搜索了半天，一直不明白是什么缘由，曾经想过在项目打包时对JSP进行预编译是否能解决问题，没有找到相应的方法。eclipse
后来想一想应该是JSP依赖的问题，故将maven配置修改成：jsp
<dependency>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jsp-2.1-glassfish</artifactId>
<version>9.1.02.B04.p0</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
在进行打包，放到服务器端运行，再也不报错！
可是暂时还没明白是什么具体缘由，先备注之。
