    CDI SE - bootstraping in a standalone app

    Ondrej Zizka Master

      Hi,

       

      I'm trying to get CDI working in a standalone app.

      Following http://docs.jboss.org/weld/reference/latest/en-US/html_single/#weld-se ,

      I added weld-se artifact, and my app now looks like this:

       

      @Singleton

      public class MyApp {

         public static void main(String[] args) throws AppException { ... }

      }// class

       

      public class MyAppWeld {

       

         public static void main(String[] args) throws AppException {

       

            WeldContainer weld = new Weld().initialize();

            MyApp app = weld.instance().select(MyApp.class).get();

            myApp.main(args);

         }

      }// class

       

       

      <?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:include name="**"/>    </weld:scan>
      </beans>
      

       

      This way, I'd expect Weld to bootstrap and start working on the app object and further on the graph of deps.

      But that doesn't happen, and  I get:

       

      33 [main] INFO org.jboss.weld.Version - WELD-000900 1.1.1 (Final)
      54 [main] INFO org.jboss.weld.Bootstrap - WELD-000101 Transactional services not available. Injection of @Inject UserTransaction not available. Transactional observers will be invoked synchronously.

      273 [main] WARN org.jboss.interceptor.util.InterceptionTypeRegistry - Class 'javax.ejb.PrePassivate' not found, interception based on it is not enabled
      Exception in thread "main" org.jboss.weld.exceptions.UnsatisfiedResolutionException: WELD-001308 Unable to resolve any beans for Types: [class org.jboss.myapp.MyApp]; Bindings: [@javax.enterprise.inject.Default()]

          at org.jboss.weld.bean.builtin.InstanceImpl.get(InstanceImpl.java:108)
          at org.jboss.jawabot.JawaBotAppWeld.main(JawaBotAppWeld.java:17)
      

       

      What am I doing wrong?

       

      Thanks,

      Ondra
