    Weld on JBOSS causes NPE

    Mahmut Izci Newbie


      I'm trying to run a simple CDI example on latest nightly builded JBOSS 6.
      Runnig the example causes a NPE:

      Caused by: java.lang.NullPointerException
              at de.SoapService.sayHello(SoapService.java:26) [:]
              at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [:1.6.0_17]

              ... 41 more

      My goal is to inject a utility class into another class:

      public class UtilBean {
          public UtilBean(){}
          public String doSomething(String message){
           return "made something with parameter " + message;

      @WebService(targetNamespace = "http://de.com/soap", serviceName = "SoapService")
      @SOAPBinding(style = SOAPBinding.Style.RPC)
      public class SoapService {
           @Inject private UtilBean utilBean;
           public String sayHello(@WebParam(name="message") String message){
                System.out.println("calling utilBean: " + this.utilBean.doSomething(message));
                return "saying hello from soapservice to " + message;

      The injected UtilBean is always null and I don't now why.

      Thanks in advance.
