Vaadin-cdi + weld + tomcat7 problem

Flow

Hi all,

Vaadin-cdi + weld + tomcat7 problem

First, I create a vaadin project, and add weld-servlet.jar, vaadin-cdi-1.0.0.jar into WEB-INF/lib,
then it happend NullPointerException when tomcat starting.
Following are error messages:

public static Set getUiBeans(BeanManager beanManager)
{
    Set uiBeans = beanManager.getBeans(com/vaadin/ui/UI, new Annotation[] {
        new AnnotationLiteral() {

        }
    });
    return uiBeans;
}

I think the beanManager is Null, so how to initialize the beanManager when tomcat starting?

Thanks,
Evan

Hi, same here.

I have try to enable CDI in Tomcat like is described her: http://docs.jboss.org/weld/reference/1.0.0/en-US/html/environments.html#d0e4998, but the BeanManager is still null.

My maven-project contains dependencies for vaadin-cdi 1.0.0.alpha1 and weld-servlet 2.0.2.Final.

I have already tried to run the vaadin-cdi-example-Webapp but this stops with the same error.

Thanks,
Andre

Hi,

I got this error when my WEB-INF/beans.xml was not “empty”. With following beans.xml it should work better:

<?xml version="1.0" encoding="UTF-8"?>
<beans>

</beans>

With Vaadin 7.2.2 + CDI in Tomcat 7 and Weld, I get this:

In com.vaadin.cdi.CDIUIProvider, there is a lookup for “java:comp/BeanManager”, but in Tomcat bind it to “java:comp/env/BeanManager”. That is the problem. I tried providing my own implementation of com.vaadin.cdi.CDIUIProvider that uses the correct lookup for Tomcat and it worked. Any chance of incorporating this special case?

6

That is a bug in the addon if both java:comp/BeanManager and java:comp/env/BeanManager aren’t checked. The lookup could be done
like this
 to prevent this error. Please file a bug against this in the
issue tracker
 so it gets fixed.

This was
ticket #12388
, with a fix coming in Vaadin CDI 1.0.0.alpha3 probably later today or tomorrow.

Hi everybody, I got to this topic, because I have a quite similiar topic : I’m using JBoss Wildfly with Vaadin CDI add-on. This works fine, as long as I don’t add a dependency to vaadin-client-compiler. Then I get a NPE for the BeanManager as well telling me furthermore, that the BeanManager couldn´t be get through JNDI. I use Vaadin version 7.2.5 in all dependencies and Vaadin CDI 1.0.0.alpha3. Since I’m a Vaadin rookie, I do not really understand, what´s happening here, that just adding a dependency breaks CDI. What did I wrong here ?
This is my pom.xml:

As Joernpeter Pook mentioned we simply added vaadin-client-compiler as dependency to your vaadin-cdi-example project pom.xml and after this project stopped to work. Reporting the same error as shown in Joernpeter Pook question. ticket #12388 doesn’t solve this problem.

This is my UI:

[code]
package com.example.vaadinjaasecdi;

import com.vaadin.cdi.CDIUI;
import com.vaadin.server.VaadinRequest;
import com.vaadin.ui.Label;
import com.vaadin.ui.UI;

@SuppressWarnings(“serial”)
@CDIUI(value = “exampleUI”)
public class VaadinjaasecdiUI extends UI {

@Override
public void init(VaadinRequest request) {
    Label label = new Label("Hello Vaadin user");
    setContent(label);
}

}
[/code]My dependencies:

<!-- Vaadin CDI  -->
        <dependency org="com.vaadin" name="vaadin-cdi" rev="1.0.0.alpha3" /> 
        <!-- WELD -->
        <dependency org="org.jboss.weld" name="weld-core" rev="1.1.5.Final"/>
11

I found a solution. for the nullpointer problem

1º have an empty beans.xml in your /web-inf/ diretory
2º update your Ivy.xml with those dependencies:

[code]

    <dependency org="com.vaadin" name="vaadin-cdi" rev="1.0.0.beta1" />
    <!-- WELD -->
    <dependency org="org.jboss.weld" name="weld-core" rev="1.1.5.Final"/>
    <dependency org="org.jboss.weld.servlet" name="weld-servlet" rev="2.2.4.Final"/>

[/code]Are done, those steps solved my nullpointer problem… but created other… :frowning:
