tomcat启动后为什么访问http://localhost:8080不行，而http://127.0.0.1:8080就没有问题？
访问localhost会提示网页无法打开！多次尝试都如此！hosts文件如下：
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost

高手指点一下！谢了！

你找下系统下(2000:c:\winnt\system32\有个hosts文件，用文本打开看有没有：
127.0.0.1 localhost

与连接上网络有关吗？

你用的jdk版本是什么？
Tomcat5.5.x需要jdk5.0
Tomcat5.0.x需要jdk1.4.2

[luojia1108]

jdk5.0_06的。用是可以，只是想弄明白！呵呵！现在只好用回tomcat 5.0.28的了！

我的tomcat也是如此，不知道是不是设了代理的缘故。其实用起来都一样

谢谢楼上的！
我现在换了个tomcat 5.0.28都行了！奇怪！原来用tomcat 5.5.15和5.5.16的不行（接上网络就访问不了，断开网络测试就可以）！
我的是XP sp2系统。hosts文件里也有127.0.0.1 localhost
