In many cases you will be not able to install the GWT browser plugin from internet. For example if you work in company using some proxy to connect to internet. In most of the cases this affects the GWT IE plugin. Normally when you try to open the GWT development mode link, if the browser does not have the GWT Plugin installed, it shows a link where you can download the plugin. If for some reason you don’t have the possibility to download the plugin or in case of IE you may download it but the installation wants to connect to Internet to finish the process, you have to download the installation files and install the plugin offline. I was looking for possibility to install the plugins offline as well and this is what I found so far.
The links for Firefox, Chrome and Safari were not really very complicated to figure out but for Internet Explorer, it was a little bit complicated. I just decide to browse in the GWT source code and here are the links I found:
You can use the following links to download the plugins for Firefox, Chrome and Safari and then you can proceed offline installation on computer without internet access.
Now for Internet Explorer the link construction above does not work. You should browse inside the GWT code and download the installation from there. The link: http://google-web-toolkit.googlecode.com/svn/trunk/plugins/ and then inside the folder ie/prebuilt/.
NOTE: Use the above only if you don’t have internet access. If you are able to install the plugins directly from Internet, this is always the best way and guaranties you that you do have the latest version!
