Injecting application-scope variable

[gtnguyen]

Hello there,

I have a singleton that auto-starts and stores some database values in application-scope variables.

When I try to access the variables on the HTML page, it works fine.

When I try to inject the variables into a Seam Action bean, I get 'null' values.

I'm new to Seam.  Any help would be appreciated.  Code snippet below.

Cheers,
G.T. Nguyen

@Local
public interface ApplicationParams
{
    public void onCreate(Component self);
    public String getTest();
}

@Name("applicationParams")
@Startup
@Scope(ScopeType.APPLICATION)

public class ApplicationParamsBean implements ApplicationParams
{
    private String test = "";

    @Create
    public void onCreate(Component self) {

     // retrieve value from database
     test = "something";
    }

    public String getTest() {
     return test;
    }
     
}


<ui:composition>
<ui:define name="body">
  #{applicationParams.test}
</ui:define> 
</ui:composition>


// Test Bean
@Stateless
@Name("test")
public class TestBean implements Test
{
     @In("#{applicationParams.test}") private String test;
     // test returns null (???)

}

Are you letting seam create the bean or are you getting it via JNDI lookup?

[gtnguyen]

I suppose I can move

@In("#{applicationParams.test}") private String test;

to another bean that Seam is definitely creating ... something like this wouldn't work, would it?

TestBean test = new TestBean();

I'm porting an old application over to Seam, so pardon me if I'm doing something wrong here.

Thanks again,

You have to let seam create the bean, otherwise it does not have the chance to add it interceptors that handle bijection.
Try this:

Test test = (Test)Component.getInstance("test");

I moved the @In declaration to another Seam-created bean, and it's working now.  Thank you very much for your help.
