It is very easy to have GWT Jquery integration using gwtquery. Follow below
steps
Add maven dependency for gwtquery, at the time of writing this article it
was 1.4.2 and tested it with GWT 2.5.0 version.
<dependency>
<groupId>com.googlecode.gwtquery</groupId>
<artifactId>gwtquery</artifactId>
<version>1.4.2</version>
<scope>provided</scope>
</dependency>
Then inherit your module from required gwtquery module.
<inherits name='com.google.gwt.query.Query'/>
User jquery api wrappers as follows.
import static com.google.gwt.query.client.GQuery.$;
..
...
public class GwtJquery implements EntryPoint {
@Override
public void onModuleLoad() {
$("#startup").fadeIn(1000);
$("#product").delay(2000).fadeIn(1000);
}
...
...
}
