Question

I am trying to make weld-se work in a very simple example, which basically follows this one. However, I can't get it work.

I use gradle for building. Here is my build.gradle:

apply plugin: 'java'

version='1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

task wrapper(type: Wrapper) {
    gradleVersion = '1.8'
}

jar {
    dependsOn configurations.runtime
    from { configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) } }
}

task hello( type: JavaExec) {
    main = 'org.jboss.weld.environment.se.StartMain'
    classpath = sourceSets.main.runtimeClasspath
}

dependencies {
    compile 'org.jboss.weld.se:weld-se:2.0.4.Final'
}

I have these files in the src folder.

./src/main/java/weldse/HelloWorld.java
./src/main/resources/META-INF/beans.xml

The contents are listed below.

HelloWorld.java

package weldse;

import org.jboss.weld.environment.se.events.ContainerInitialized;

import javax.enterprise.event.Observes;

public class HelloWorld {

    public void printHello( @Observes ContainerInitialized event) {
        System.out.println("Hello, World");
    }
}

beans.xml

<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
                           http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
       version="1.1" bean-discovery-mode="all">
</beans>

When I run gradle hello, I don't get the output Hello, World but a BUILD SUCCESSFUL with these messages:

[main] INFO org.jboss.weld.Version - WELD-000900 2.0.4 (Final)
[main] INFO org.jboss.weld.Bootstrap - WELD-000101 Transactional services not available. Injection of @Inject UserTransaction not available. Transactional observers will be invoked synchronously.

[main] WARN org.jboss.weld.interceptor.util.InterceptionTypeRegistry - Class 'javax.ejb.PrePassivate' not found, interception based on it is not enabled

However, when I run it directly with java, I get exceptions. Here is full stacktrace.

It seems to me there is an ambiguity of InstanceManager that is causing the exceptions. However, I don't know for sure. Anyway, do you know how to make this work? Thank you very much.

Was it helpful?

Solution

It appears that this is an issue to weld-se, and is not going to be fixed any time soon. In any case, I found a workaround for it, which basically excludes bean scanning for weld. In case the link to the workaround expires in the future, here is the workaround beans.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:weld="http://jboss.org/schema/weld/beans"
    xsi:schemaLocation="
          http://java.sun.com/xml/ns/javaee http://docs.jboss.org/cdi/beans_1_0.xsd
          http://jboss.org/schema/weld/beans http://jboss.org/schema/weld/beans_1_1.xsd">
    <weld:scan>
        <weld:exclude name="org.jboss.weld.**" />
    </weld:scan>
</beans>

Basically, what you need to do is merge this beans.xml with your current beans.xml.
