really need some help.

I have been working for the past 3 days trying to get a webpage to open when I run my web based Java-GWT-eclipse program. IE gives me error "Internet Explorer cannot display webpage" and chrome says "The webpage is not available- The server at gwt.google.com can't be found, because the DNS lookup failed."

I have tried this project on multiple other computers with an older eclipse-gwt plugin installed and it works great. All of these computers are dev boxes and do not have internet access. It does, however, have a solid connection to the database (SQL dev works fine).

what i have tried

  1. copied eclipse and gwt plugin files from another dev box and installed. Gave me above error.

  2. deleted/ uninstalled everything and installed newest version eclipse and gwt plugin. I was able to install gwt in eclipse but it could not locate GWT-user.jar file and would not allow me to create project.

  3. Tried #2 again, same problem. Tried again on another computer, same problem.

  4. Applied older version SDK to newer eclipse version. Gave same error as posted above/ #1.

  5. ran wireshark on a working dev and the problem dev and the problem dev box was trying to communicate with google while the good one was going to some local IP address.

  6. messed around with every setting in eclipse and nothing has worked.

What is left to try??? I am going insane.

您要打开的网页是什么：http://gwt.google.com？

如果您直接在浏览器的地址框中输入 url，此页面是否会加载？

互联网可以在那台计算机上工作吗？尝试访问谷歌或任何其他页面。

此错误是您的 PC Internet 堆栈上配置错误的明显案例：

The server at gwt.google.com can't be found, because the DNS lookup failed.

什么会在您的控制台中返回此命令？

nslookup gwt.google.com

编辑：

阅读您的评论后，我弄清楚发生了什么：您的浏览器没有安装 gwt-plugin，所以第一次连接到 gwt-dev-mode 应用程序时，应用程序会将其重定向到 gwt 站点以下载插件并安装它。

您可以将这台计算机连接到 Internet 以在第一次请求时安装该插件，或者下载该插件并手动安装。
