Example

public class BeanClass implements javax.ejb.EntityBean {
public Object returningMethod () {
//..
return this;
}

//other methods that must implement the interface
}

Solution
Avoid returning this. Use getEJBObject() instead.


public class BeanClass implements javax.ejb.EntityBean {
public Object returningMethod () {
//..
return this.getEJBObject();
}

//other methods that must implement the interface
}
