ClassNotFoundException for my local interface on Jboss7 startup

[rumiat]

I have JBoss7 Final and seam 2 application. My EJB is defined something like

MyEJBBean.java

@Stateless

@AutoCreate

@Name("MyEJB")

@JndiName(value = "java:app/ejb-1.0/MyEJBBean")

public class MyEJBBean implements MyEJB {

    .

    .

    .

}

and corresponding local interface is defined as

MyEJB.java

@Local

public interface MyEJB{

    .

    .

    .

}

Both of above are in the same my-ejb.jar

Components.xml

<!-- <core:init jndi-pattern="my-app/#{ejbName}/local"/> -->

JNDI pattern is commented as I am using JBoss 7. Now I am getting ClassNotFoundException for my local interface on Jboss startup.  Any idea???

Where exactly in the .ear, is the ejb-jar.jar placed?

[rumiat]

The structure is as follow:

.ear

      - ejb-jar.jar

      - my-war.war

      - META-INF

          - jboss-deloyment-structure.xml

      - lib

          - other-jar1.jar

          - other-jar2.jar

Whereas my interface and session bean is in ejb-jar.jar. Any idea?

Can you attach your appilcation which reproduces this issue?, Also, I couldn't see your application.xml file, is it missing?

[rumiat]

application.xml is there I just did not show it over there at ear\META-INF\application.xml and it contains

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE application PUBLIC

          "-//Sun Microsystems, Inc.//DTD J2EE Application 1.3//EN"

          "http://java.sun.com/dtd/application_1_3.dtd">

<application>

  <display-name>my-app</display-name>

  <description>my app.</description>

  <module>

    <web>

      <web-uri>my-web-1.0.war</web-uri>

      <context-root>/myweb</context-root>

    </web>

  </module>

  <module>

    <ejb>my-ejb.jar</ejb>

  </module>

</application>

Further I have jboss-app.xml at the same location which is ear\META-INF\application.xml and it contains

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE jboss-app PUBLIC

          "-//JBoss//DTD J2EE Application 1.4//EN"

          "http://www.jboss.org/j2ee/dtd/jboss-app_4_0.dtd">

<jboss-app>

  <unauthenticated-principal>guest</unauthenticated-principal>

  <loader-repository>seam.jboss.org:loader=my-app</loader-repository>

</jboss-app>

One more thing which might be of your interest is that I am getting following warning along above exception

WARN  [org.hibernate.cfg.AnnotationBinder] (MSC service thread 1-1) HHH00194:Package not found or wo package-info.java: com.my.package

And this is the same package where MyEJB interface is present.

[rumiat]

I found the answer I was invoking my bean something like

@In(create=true)

private MyEJB myEjb;

I replaced it to

@EJB(lookup=“java:app/my-ejb/MyEJBBean!com.my.MyEJB")

private MyEJB myEjb;
