SeamResourceBundle or injected messages are always null

[dish13]

I'm trying to inject Seam messages into a Seam component (EJB) but no matter where I place the messages.properties (currently I have in the WEB-INF/classes) the variable is always null. I've also tried placing the messages.properties file in the ejbModule but it is always null.

Any recommendations?

WEB-INf/classs should be a good place for this.

And you must define the following lines in the components.xml too:

     <core:resource-loader>
          <core:bundle-names>
               <value>messages_first</value>
               <value>messages_second</value>
          </core:bundle-names>
     </core:resource-loader>

I don't understand; why messagesfirst and messagessecond? I have only one property file (messages.properties).

It was only an example (you can have more than one property file). In your case use:

<core:resource-loader>
  <core:bundle-names>
   <value>messages</value>
  </core:bundle-names>
</core:resource-loader>

Yes, but my resource bundle is already define in my components.xml and still when I inject the messages is null.
I've tried @In(value="#{messages['test']}") private String testMsg; and I have no problems.

Amy, please post your full class code where you do injection. For entire map of messages it should be :

@In
private Map<String,String> messages;

I also do not understand the last sentence. Do you mean that injecting particular message works and injecting whole bundle fails ?

[dish13]

Yes, I have no problems with injecting a particular message. I only have problems when injecting the message map.

Here's the class:

@Stateful
@Name("pos")
@Scope(ScopeType.CONVERSATION)
@Interceptors( { org.jboss.seam.ejb.SeamInterceptor.class })
public class POSActionBean implements POSAction, Serializable {

     private static final long serialVersionUID = 20100125L;
     @Logger
     private Log log;
     @In
     StatusMessages statusMessages;
     @In
     EntityManager entityManager;
     @In(scope=ScopeType.SESSION)
     private Employee currEmployee;
     @In
     private Map<String, String> messages;

     @Begin(join = true, flushMode = FlushModeType.MANUAL)
     public String begin() {
          return "pos";
     }

     public String next() {
          return "services";
     }

     @End
     public String end() {
          return "end";
     }

     @Destroy
     @Remove
     public void destroy() {
     };
}

Hi,

I had a simular problem. I think I know how you can solve your problem (unless you solved it already).
Change the lines which inject your messages Map with:

  @In(value="#{messages}")
  private Map<String, String> messages;

You use a EJB (like I did). The EJB is not created by Seam and I think the @In doesn't work well for the built in resource bundle seam component configured in components.xml. Maybe this is a bug?
It also explains why injecting a single message works, because the el expression for messages is used.
