Extending ApplicationConnection issue

malcolm4 · December 10, 2014, 6:15pm

I want to extend the ApplicationConnection with MyApplicationConnection.

The build fails with java.lang.NoClassDefFoundError: com.example.VaadinSimpleMvn.MyApplicationConnection.

I attached a very simple maven project that fails.

Steps

Created a new vaadin project using project type vaadin-archetype-application version 7.3.6.
Verified everything works by using Jetty, and then doing a simple deployment to Tomcat.
Create a new class MyApplicationConnection that extends ApplicationConnection
Add the following to AppWidgetSet.gwt.xml that is generated by vaadin-archetype-application
Compile widgetset successful with maven using
vaadin:update-widgetset
Complete build using maven options
clean compile vaadin:compile package

NoClassDefFoundError error occurs

Environment

Maven: maven-3.2.3
Eclipse: Luna Service Release 1 (4.4.1) Build id: 20140925-1800
Java: version “1.7.0_71” build 1.7.0_71-b14

The following is the maven output with the vaadin plugin in strict mode.

Found the root cause.

The component extensions have to be located under the client package next to MyWidgetSet.gwt.xml.

See Project Structure in 16.1. Overview https://vaadin.com/book/-/page/gwt.html

Others have had this issue and found the solution at

http://stackoverflow.com/questions/8386011/vaadin-compile-widgetset-using-maven

After all the discussion about decoupling in Vaadin technology, there are still special situations.

Seems like this need to be better documented or added to some list.
