Problem :

 org.hibernate.AnnotationException: No identifier specified for entity:

 Solution:

 You are missing a field annotated with @Id.

 Each @Enitity needs an @Id - this is the primary key in the database.

 If you don't want your entity to be persisted in a separate table, but rather be a part of other entities, you can use @Embeddable instead of @Entity.

This will disable collection of dependencies specified by an annotation processor when Filer methods are called

javax.servlet.ServletException: Circular view path

By
Problem : javax.servlet.ServletException: Circular view path [error]: would dispatch back to the current handler URL [/latestOrder] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.) Solution : You've annotated the controller method as producing JSON or String or any other object . You probably want to annotate the method with @ResponseBody and change its return type to allow you to return an object representation of the JSON that you want to include in the response Preview: @RequestMapping (value= "latestOrders" ,method = RequestMethod. GET ) public @ResponseBody List<Order> listProducts(Model model) throws JMSException{ List<Order> list= new ArrayList(); list. add (staff1) return list; }
