Mavenized Liferay Portlet 2.0 using Spring

Hello all,

I have no idea if anyone else has ever encountered an issue such as this one, but it has me baffled.

In short: a ‘getContext’ within my init() method in my portlet-application class returns an object of type ‘WebApplicationContext’ instead of the expected PortletApplicationContext2

A relevant code snippet from my application class:

import com.vaadin.terminal.gwt.server.PortletApplicationContext2;
import com.vaadin.terminal.gwt.server.PortletApplicationContext2.PortletListener;

public class Dante extends Application implements PortletListener {
public void init() {
		log.debug("init() called");
		... // non relevant code

		log.debug("getContext().getClass().getSimpleName() = " + getContext().getClass().getSimpleName());

		if (getContext() instanceof PortletApplicationContext2) {
			PortletApplicationContext2 ctx = (PortletApplicationContext2) getContext();

			// Add a custom listener to handle action and
			// render requests.
			ctx.addPortletListener(this, this);
		} else {
					"Not initialized via Portal! - context not of type PortletApplicationContext2",

Console output when starting my server & loading my app:

As you can see at the bottom: WebApplicationContext.
And loading the portlet shows me the ErrorNotification-window.

There is one other thing that might be worth mentioning: I’m using Maven to handle my dependencies & my building.

Other information regarding the project build up can be provided on request or you could click and check

So anyone care to give me any insights? Thoughts? Comments?

thanks in advance for any and all feedback!


I have found a workaround for this problem.

Stop the server
clean the following folders of your app-specific entries:

Place your war in the deploy folder

restart server.

Though I must admit this is a really ugly way of testing & redeploying…

Hi, I am also trying to develop a Vaadin portlet in liferay and using Spring for dependency injection.
I am facing issues with it. Can you please help me by sending your sample source code like web.xml , spring-application.xml etc and few Vaadin
application classes.
I am getting below error. I have configured RequestContextFilter in my web.xml but I am not sure why I am getting this error still.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘memberGeneric’ defined in file [C:\liferay-portal-tomcat-6.1.0-ce-_05_09\liferay-portal-6.1.0-ce-ga1\tomcat-7.0.23\webapps\VaadinProject-portlet\WEB-INF\classes\com\magellanhealth\memberinfo\MemberGeneric.class]
: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.magellanhealth.memberinfo.MemberGeneric]
: Constructor threw exception; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
