Apache Tomcat/5.0.28

是这样的，我把jdk装在了D盘TOOLS下

JAVA_HOME=D:\TOOL
path=%JAVA_HOME%\bin
classpaht=.;=%JAVA_HOME%\lib\dt.jar;  .....................等

之后，我编了一个java文件，在DoS下经过编绎( javac HelloWord.java )
解释正确显示

手动把tomcat服务启动，打开IE后sp页面可以浏览了;
用myeclipse进行操作，在其里面启动tomcat服务后，在IE里浏览jsp就不可以，
这是怎么个情况哩？~

我的ie没有设置代理服务器,
电脑上了网啊的
