liferay 7 VaadinPortlet (with vaadin 8.1.1)

Hello.
I don’t find the way to configure to use the VaadinPortlet class.

Using maven archetype “vaadin-archetype-liferay-portlet” like:
mvn archetype:generate
-DarchetypeGroupId=com.vaadin
-DarchetypeArtifactId=vaadin-archetype-liferay-portlet
-DarchetypeVersion=8.1.1

Work the portlet in liferay 7, but, I need extends VaadinPortlet to use “doView” and “doEdit”

In liferay 6.2 with vaadin 7 the way is extending VaadinPortlet and work well.

In Vaadin 8.1.1 I try something like this:

@Theme(“mytheme”)
@SuppressWarnings(“serial”)
@Widgetset(“biz.ideasoft.vaadin.AppWidgetSet”)
@Component(service = VaadinPortlet.class, property = {
“com.liferay.portlet.display-category=category.sample”,
“javax.portlet.name=MyVaadinPortlet”,
“javax.portlet.display-name=My Vaadin portlet”,
“javax.portlet.security-role-ref=power-user,user”,
“javax.portlet.portlet-mode=text/html;VIEW,EDIT”,
“com.vaadin.osgi.liferay.portlet-ui=true”,
“javax.portlet.init-param.UI=vaadin.test.ui.TestUI”
})
public class MyPortletUI extends VaadinPortlet {

}

But i coudn’t see the portlet available to use.
Any ideas?
Thank
Diego

Hello again.
I had a little advance.

Create the class:

package biz.ideasoft.vaadin;

@Theme(“mytheme”)
@SuppressWarnings(“serial”)
@Widgetset(“biz.ideasoft.vaadin.AppWidgetSet”)
@Component(service = Portlet.class, property = {
“com.liferay.portlet.display-category=category.sample”,
“javax.portlet.name=VaadinPortletUI”,
“javax.portlet.display-name=Vaadin Portlet UI”,
“javax.portlet.security-role-ref=power-user,user”,
“javax.portlet.portlet-mode=text/html;VIEW,EDIT”,
“com.vaadin.osgi.liferay.portlet-ui=true”,
“javax.portlet.init-param.UI=biz.ideasoft.vaadin.TestVaadinUI”,
“com.liferay.portlet.instanceable=true”})
public class VaadinPortletUI extends VaadinPortlet {

}

And the class “biz.ideasoft.vaadin.TestVaadinUI”

public class TestVaadinUI extends UI {
protected void init(VaadinRequest request) {

}
}

But a get a Class Loader error:

  2. I did : “mvn package” in the folder of the generate project
  3. I copy the generated Jar file in target folder to the deploy folder os the liferay 7 I have running in a server.
  4. then in the log it says : [code] [code] 00:28:49,538 INFO [com.liferay.portal.kernel.deploy.auto.AutoDeployScanner] [AutoDeployDir:252] Processing CaixaV-Solicitud-Credito-1.0-SNAPSHOT.jar [code] but nothing else
    [/code]
    [/code]
    [/code]
  5. But I can’t see the portlet available to use.

i guess I am in he same situation of your first mesage, but then you say that you got a litle avance after adding a new class, and the advance is that you get a error,
but why you add this second class biz.ideasoft.vaadin.TestVaadinUI?
As this is 6 months old, did you finally were able to make it work?
did you follow the same steps I did?
do I missing some step?
