Jetty服务器报错-蒲公英云

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

解决方法，在mvn的pom.xml文件中加入：

org.mortbay.jetty
jsp-2.1
provided

7.0.0pre2

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/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 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

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
