Example

public class BeanClass implements javax.ejb.MessageDrivenBean {
public void ejbCreate () {
//empty body
}
//other methods that must implement the interface
}

Solution
Always implement at least one ejbCreate() method in a MessageDrivenBean class.


public class BeanClass implements javax.ejb.MessageDrivenBean {
public void ejbCreate () {
//non-empty body
}
//other methods that must implement the interface
}
