The GWT Development Plugin for chrome is now accessible from the google chrome store; https://chrome.google.com/webstore/detail/gwt-developer-plugin/jpjpnpmbddbjkfaccnmhnkdgjideieim Up until recently the Gwt Chrome plugin hadn't been accessible from the chrome store search function. So I had to install the plugin manually using this work around Curtosey of is...@google.com; Quick fix that might help: 1. right click on the chrome icon>Properties>Shortcut 2. add in target: --enable-easy-off-store-extension-install 3. open chrome and navitage to extensions ( chrome://chrome/extensions/ ) 4. drag and drop on it the plugin (should be in your download folder if you tried to install it before and didn't succeed) I Just found out today despite having the plugin installed I was getting a GWT plugin not installed message in chrome.

Here's how I got the examples that come with GXT 3 working, in six simple steps! 1. Setup a GXT 3 app Setup your Gxt app as shown in the previous post on this blog; Quick Setup for GXT 3 . 2. Add additional jars In addition to the gxt jar there are several other jars that need to be added to the build path; gxt-3.0.0.jar gxt-chart-3.0.0.jar gxt-legacy-3.0.0.jar uibinder-bridge-2.4.0.jar gwt-dev.jar gin-1.5-post-gwt-2.2.jar guice-3.0.jar json-org.jar javax.persistence.jar javax.inject.jar That will fix all of the errors except for 2 in the file Folder.java, (I'm not sure how to fix that one yet, answers on a post card please. I tried using the  javax.persistence.jar from J2EE / Glassfish modules but this didn't fix it for me, so I just had the methods with errors return null ). 3. Import the examples Select the src folder in your project (eclipse), select "file import" navigate to the examples-src folder inside the gxt 3 download and se

A really great resource when migrating to Extjs4, and to anyone new to Extjs in general this would be a great place to start.
