Dependency injection/annotation Error

[Jose Campana]

Greetings,

Hello everybody !

This topic's about a problem I'm currently experiencing while trying to deploy a Web Application that makes a call to an EJB using Dependency injection from a Servlet. This is the Stack trace generated when I attempt to deploy my web app:

DeployerRunnable.run Error parsing annotation for class org.servlet.TestServletoracle.oc4j.admin.internal.DeployerException: Error parsing annotation for class org.servlet.TestServlet
at oracle.oc4j.admin.internal.DeployerBase.execute(DeployerBase.java:126)
at oracle.oc4j.admin.jmx.server.mbeans.deploy.OC4JDeployerRunnable.doRun(OC4JDeployerRunnable.java:52)
at oracle.oc4j.admin.jmx.server.mbeans.deploy.DeployerRunnable.run(DeployerRunnable.java:81)
at com.evermind.util.ReleasableResourcePooledExecutor$MyWorker.run(ReleasableResourcePooledExecutor.java:303)
at java.lang.Thread.run(Thread.java:619)

Here's a Snippet from the Servlet that's making the call:

public class TestServlet extends HttpServlet {
	
	@EJB(beanName="MathEjbBean")
	private org.logic.MathEjbBeanRemote ejb;
	
	protected void doGet(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {
		
		ejb.sum(1, 2);
		.
                .
                .
         }
}

Here's the EJB implementation:

@Stateless
@StatelessDeployment
public class MathEjbBean implements MathEjbBeanRemote, MathEjbBeanLocal {

	@Override
	public int sum(int a, int b) {
		// TODO Auto-generated method stub
		return a + b;
	}
}

Finally, I will post the Container-specific Deployment descriptor:

<?xml version="1.0" encoding="utf-8"?> 
<orion-ejb-jar xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/orion-ejb-jar-10_0.xsd" deployment-version="" deployment-time="128f9bdc917" schema-major-version="10" schema-minor-version="0" > 
      <enterprise-beans> 
            <session-deployment name="MathEjbBean" tx-retry-wait="60" location="MathEjbBean" local-location="MathEJB_MathEjbBeanLocal" persistence-filename="MathEjbBean"> 
            </session-deployment> 
      </enterprise-beans> 
      <assembly-descriptor> 
            <default-method-access> 
                  <security-role-mapping name="<default-ejb-caller-role>" impliesAll="true" /> 
            </default-method-access> 
      </assembly-descriptor> 
</orion-ejb-jar> 

Up until this moment, I still have no clue, about the reason why I can't inject my EJB in the Web-app's Servlet.

Please Help ! Please........

It's so hard to find info. about this problem on the internet.

Best Regards,

Jose.

Hello there !

I've corrected this problem by using the same name for the @Stateless annotation and the display-name tag in the ejb-jar file, for @EJB this name should match also.

Good Luck, hope this is helpful in the future.
