**install: http://wiki.eclipse.org/Jetty/Howto/Install\_Jetty**

wget http://dist.codehaus.org/jetty/jetty-hightide-8.0.0/jetty-hightide-8.0.0.v20110901.tar.gz
    tar xfz jetty-hightide-8.0.0.v20110901.tar.gz
    cd jetty-hightide-8.0.0.v20110901
    java -jar start.jar

`cd ~` `/` `downloads`

`wget` `-` `c http:` `/` `/` `dist.codehaus.org` `/` `jetty` `/` `jetty` `-` `hightide` `-` `8.0` `.` `0` `/` `jetty` `-` `hightide` `-` `8.0` `.` `0.v20110901` `.tar.gz`

**1,Jetty启动时报错： **[NO JSP Support for /, did not find org.apache.jasper.servlet.JspServlet][NO JSP Support for _ did not find org.apache.jasper.servlet.JspServlet]

解决方法，在mvn的pom.xml文件中加入：

<dependency>  
    <groupId>org.mortbay.jetty</groupId>  
    <artifactId>jsp-2.1</artifactId>  
    <scope>provided</scope>

</dependency>

***嚓。。。jetty-distribution-8.0.0.M2果断是有这个问题的，直接换个也可以没有啊eg:jetty-distribution-8.1.10.v20130312***

**2,访问Jetty的JSPdemo（[http://localhost:8080/jsp/][http_localhost_8080_jsp]下）报错：PWC6345: There is an error in invoking javac.  A full JDK (not just JRE) is required**

## [http://localhost:8080/jsp/dump.jsp][http_localhost_8080_jsp_dump.jsp] ##

## HTTP ERROR 500 ##

## Problem accessing /jsp/dump.jsp. Reason: ##

PWC6345: There is an error in invoking javac.  A full JDK (not just JRE) is required

### Caused by: ###

org.apache.jasper.JasperException: PWC6345: There is an error in invoking javac.  A full JDK (not just JRE) is required

原因：安装jdk的时候会往c盘的系统目录拷贝Java的课执行文件java.exe， 使用 java -jar start.jar 来启动 Jetty 时则优先使用的是系统目录下的 java.exe，这样Jetty的Jsp解析器将无法解析JDK的的安装目录

解决方案：写了个启动bat,

start.bat:

set JAVA\_HOME=E:\\KAI\_FA\\JAVA\\jdk1.6.0\_38  
E:\\KAI\_FA\\JAVA\\jdk1.6.0\_38\\bin\\java -jar start.jar

**3,jetty**

解决方案：解开start.ini文件注释掉的参数：-Dorg.apache.jasper.compiler.disablejsr199=true

**org.apache.jasper.JasperException: PWC6345: There is an error in invoking****javac.  A full JDK (not just JRE) is required **

解决方案：删除 C:\\WINDOWS\\system32\\java.exe 重启jetty

**org.apache.jasper.JasperException: PWC6033: Error in Javac compilation for JSP||PWC6199: Generated servlet error:|程序包com.sun.image.codec.jpeg不存在||**
