my nuxeo component exposed as service is not injected in my action bean

geekonspace — Thu, 31 May 2012 14:33:52 GMT

Hi, I have developed my own nuxeo component exposed as service with my "nuxeo ide", but it is not injected in the bean action where it is used. I have this files in my plugin:

component xml:

code in MyService:

public class MyService extends DefaultComponent implements MyManager {

	public static final ComponentName ID = new ComponentName(
			"my.component.MyService");

	private static final Log log = LogFactory.getLog(TypeService.class);


	protected Bundle bundle;

	public Bundle getBundle() {
		return bundle;
	}

	/**
	 * Component activated notification. Called when the component is activated.
	 * All component dependencies are resolved at that moment. Use this method
	 * to initialize the component.
	 * <p>
	 * The default implementation of this method is storing the Bundle owning
	 * that component in a class field. You can use the bundle object to lookup
	 * for bundle resources:
	 * <code>URL url = bundle.getEntry("META-INF/some.resource");</code>, load
	 * classes or to interact with OSGi framework.
	 * <p>
	 * Note that you must always use the Bundle to lookup for resources in the
	 * bundle. Do not use the classloader for this.
	 * 
	 * @param context
	 *            the component context. Use it to get the current bundle
	 *            context
	 */
	@Override
	public void activate(ComponentContext context) {
		this.bundle = context.getRuntimeContext().getBundle();
	}


	/**
	 * Component deactivated notification. Called before a component is
	 * unregistered. Use this method to do cleanup if any and free any resources
	 * held by the component.
	 * 
	 * @param context
	 *            the component context. Use it to get the current bundle
	 *            context
	 */
	@Override
	public void deactivate(ComponentContext context) {
		this.bundle = null;
	}

	/**
	 * Application started notification. Called after the application started.
	 * You can do here any initialization that requires a working application
	 * (all resolved bundles and components are active at that moment)
	 * 
	 * @param context
	 *            the component context. Use it to get the current bundle
	 *            context
	 * @throws Exception
	 */
	@Override
	public void applicationStarted(ComponentContext context) throws Exception {
		// do nothing by default. You can remove this method if not used.
	}

	@Override
	public String getStr() {
		// TODO Auto-generated method stub
		return "test";
	}

}

code in interface:

public interface MyManager {
	String getStr();
}

in myActionBean:

@In(create = true)
protected transient TypeManager typeManager;  //its working

@In(create = true)
protected transient MyManager myManager; //its not working when I use. Example: myManager.getStr();

this error message is showed:

@In attribute requires non-null value: myActionBean.myManager Caused by: org.jboss.seam.RequiredException: @In attribute requires non-null value:

You need to use the Seam Service Bean wizard. It will expose your service as a seam component.

Thanks doguin but "Seam Service Bean Wizard" is part of "seam plugin" for eclipse or it is part of Nuxeo Plugin? because I do not see it in my ide nuxeo. Anyway, I have resolved this problem developing a seam component that initializes my service using nuxeo api.

You did exactly what the wizard does
