高手请进,是不是我的环境有问题?

摘要: 高手请进,是不是我的环境有问题?

我的环境是tomcat 5.0.28+Eclipse 3.1.2+MyEclipse4.1.1,我新建了一个jsp文件来进行测试,为何测试时会出现如下错误呢?而访问tomcat自带的例子都不会出问题,实在不解,请高手帮忙看看,我是刚学JAVA的,错误如下:

JAVA_HOME does not point to the JDK

---

你的JDK装了没有，装了配置JAVA_HOME了没有

---

eclipse->Window->Preferences->Java->Installed JREs
查看一下,这里的地址是不是指向到安装的JDK目录,注意是JDK,不是JRE

---

工程有没有部署到tomcat？

---

JAVA_HOME 与你安装的JDK路径不符

---

我靠，偶上的怎么还在做广告啊
JAVA_HOME不对.
