Vaadin 7, maven, tomcat, eclipse integration

Vaadin 6 / 7 / 8

Hi There,

I’m trying to set up a Vaadin 7 development environment using the followings:
Vaadin 7
Eclipse
Tomcat(eclipse integrated)
Maven

These doesn’t seams to be straight forward. The vaadin 7 project works fine on jetty but on tomcat only if I deploy the war(which is not the way for a dev environment)

Can anyone please help me with some guidance?

Hi,

do you mean with “deploy the war” to start/run the Vaadin-project
by project-context → Run As → Run on server?

Yes,

RunAs-> Run on Server(embeded server is Tomcat) does not work if the project is created using maven vaadin archetype in eclipse.

Before RunAs-> Run on Server I run mvn vaadin:compile, and then in browser I get “Failed to load widgetset: ./VAADIN/widgetset…”

I am using Eclipse Luna, Java 7, Tomcat 7, Embeded maven 3.2.1

If I’m packing the application in war using maven and then deploy it to a standalone server the app is working fine.

Thanks
Corneliu

Hi,

The problem your maven vaadin archetype app is not running using the Eclipse embedded Tomcat is caused by the vaadin-maven-plugin configuration in the pom.xml

<plugin> <groupId>com.vaadin</groupId> <artifactId>vaadin-maven-plugin</artifactId> <version>${vaadin.plugin.version}</version> <configuration> <extraJvmArgs>-Xmx512M -Xss1024k</extraJvmArgs> <webappDirectory>${basedir}/target/classes/VAADIN/widgetsets</webappDirectory> <draftCompile>false</draftCompile> <compileReport>false</compileReport> <style>OBF</style> <strict>true</strict> </configuration> ... The webappDirectory ${basedir}/target/classes/VAADIN/widgetsets containing your compiled widgetset will not be copied to the wtpwepapps folder of your embedded Tomcat. Even adding this folder to the Eclipse project properties - Deployment Assembly won’t work.

If you don’t need a personalized widgetset, you might want to remove the @Widgetset annotation in your UI and add the vaadin-client-compiled dependency to the pom.xml

<dependency> <groupId>com.vaadin</groupId> <artifactId>vaadin-client-compiled</artifactId> </dependency> In case you need your own widgetset, you should be able to find a workaround based on above information.

Cheers,

Hi,

@Koenraad- thanks for reply but my problem fixed by adding to Deployment Assembley the following entry:
/target/classes/VAADIN/ WEB-INF/classes/VAADIN

Hi,
Thanks for the feedback.
So Deployment Assembly worked better than I expected.
That’s good news.
