Same problem has been discussed at Setting-up GWT-Ext for GWT 1.6 with Eclipse and has been resolved.
Please have a look.
Steps to fix the issue.
- Create a js directory in the war directory of the project.
- Download ext-2.0.2.zip, unpack it and copy the contents to the js directory as shown in below snapshot.
In the project's gwt.xml file add below lines:
<inherits name='com.google.gwt.user.User'/> <inherits name='com.gwtext.GwtExt' /> ... <entry-point class='com.x.y.z.client.EntryPointClass'/> <stylesheet src="../js/ext-2.0.2/resources/css/ext-all.css" /> <script src="../js/ext-2.0.2/adapter/ext/ext-base.js" /> <script src="../js/ext-2.0.2/ext-all.js" />
