This is how you would typically work on a QWT application:

• build everything: mvn clean compile eclipse:eclipse
• start the application: mvn qx:run
• open a web browser and point it to http://localhost:8080/
• open Eclipse and start editing

Once this is done, the rest of the development process is pretty much handled automatically:

Under Linux or Mac OS X just edit a class in Eclipse, save it and press reload in your browser:

• Eclipse compiles the class to Java bytecode
• Tomcat recognizes the change and reloads the application
• QWT compiles the class to JavaScript

Under Microsoft Windows you need to run mvn compile qx:run after source changes. This is because Eclipse-compiled class files cannot be symlinked into the web application.

Advanced: You can even change a dependency jar if the version number stays the same: Just run mvn install in your dependency project and press reload in your browser. Dependencies are symlinked into the qooxdoo application, so Tomcat will recognize the change.
