try{ userTransaction.begin(); out.println("Transaction began!"+"<br/>"); em.persist(cust); //can be omitted em.flush(); em.refresh(cust); orders = cust.getOrders(); for (int i = 0; i < orders.size(); i++) { out.println("order "+ orders.get(i).getPono()+ " placed by: " + orders.get(i).getCustomer().getCust_name() + "<br/>"); } userTransaction.rollback(); out.println("Transaction has been rolled back!"); } catch (Exception e){ e.printStackTrace(); } } } The most interesting thing about the code shown in the listing is that you don t have to explicitly persist the Order instances created there to the database. The persistence provider does it implicitly when the Customer instance with which those Order instances have been associated is persisted. It s important to realize that the previous is not the default behavior. As you might recall from Table 9-1, the persistence provider does it that way here because the cascade element of the @OneToMany annotation in the Customer entity is set to ALL, which means all operations performed against a Customer instance will be cascaded to the associated Order instances. By default, the cascade element is not set at all. This means that if you modify the Customer entity as shown in the snippet in Listing 9-7, then the CascadingTestServlet servlet shown in Listing 9-6 will end up with an error, providing no output after the Transaction began! message appears. Listing 9-7. The One-to-Many Relationship Defined in the Customer Entity, Without the Cascade Annotation Element ... public class Customer implements Serializable { ... @OneToMany(mappedBy="customer") private List<Order> orders; public List<Order> getOrders(){ return orders; } public void setOrders(List<Order> orders) { this.orders = orders; } ... }

},{ "id":"3", "key":"3", "value":{ "_id":"3", "_rev":"2-832643768", "name":"Emma Watson", "phone":"555-726531", "email":"emma@example.com", "fax":"555-726532" } },{ "id":"4", "key":"4", "value":{ "_id":"4" ,"_rev":"2-1539547354", "name":"Charles Bing", "phone":"555-821345", "email":"charlesb@example.com" } },{ "id":"5", "key":"5", "value":{ "_id":"5", "_rev":"2-3630180106", "name":"Eric Quinn", "phone":"555-012796", "fax":"555-098245" } } ] } Working with temporary views is nice and easy, but as discussed earlier in this chapter, their use is limited, and they should be avoided if possible. Before you start creating permanent views using the API, let s use the curl command to access the two existing views you created in your design document /_design/contacts. You can execute a permanent view using a GET request to the URI /contacts/_design/contacts/_view/get_fax_contacts, where the second contacts in the URI is the design document name and get_fax_contacts is the view name. Let s try this using curl: curl -X GET http://127.0.0.1:5984/contacts/_design/contacts/_view/get_fax_contacts All going well, you should get a result like Listing 7-8. Listing 7-8. Result of get_fax_contacts View {"total_rows":3,"offset":0,"rows":[ {"id":"1","key":"1","value":{"Name":"John Smith","Facsimile":"555-372590"}}, {"id":"3","key":"3","value":{"Name":"Emma Watson","Facsimile":"555-726532"}},

Now, to make the CascadingTestServlet servlet shown in Listing 9-6 work again and produce the same results, you might change its source code as shown in Listing 9-8. Listing 9-8. The Updated CascadingTestServlet Servlet That Will Work with the Customer Entity Modified As Shown in Listing 9-7 //import declarations ... public class CascadingTestServlet extends HttpServlet { ... public void doGet( HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ... Customer cust = (Customer) em.find(Customer.class, 2); Employee emp = (Employee) em.find(Employee.class, 2); List<Order> orders = new ArrayList<Order>(); Order order1 = new Order(); order1.setPono(10); order1.setCustomer(cust); order1.setEmployee(emp); Order order2 = new Order(); order2.setPono(11); order2.setCustomer(cust); order2.setEmployee(emp); //Performing transaction try{ userTransaction.begin(); out.println("Transaction began!"+"<br/>"); em.persist(order1); em.persist(order2); em.flush(); em.refresh(cust); orders = cust.getOrders(); for (int i = 0; i < orders.size(); i++) { out.println("order "+ orders.get(i).getPono()+ " placed by: " + orders.get(i).getCustomer().getCust_name() + "<br/>"); } userTransaction.rollback(); out.println("Transaction has been rolled back!"); } catch (Exception e){ e.printStackTrace(); } } }

A few libraries were previously mentioned, but brace yourself. Hundreds of libraries are out there doing seemingly identical things, with more coming out almost daily. Each library might take a slightly different approach to a certain feature depending on what that developer felt was important to include. Thankfully, there s plenty of support including from large corporations for just a handful of libraries, each with its own strengths and weaknesses. Weaknesses tend to be addressed quickly by using techniques used by competing libraries or through plug-ins. One of the largest downfalls of many open-source movements is documentation. You ll certainly find that documentation can be sparse and unclear. Some libraries do a better job than others at addressing this. The current leaders of the pack are the following: Dojo Prototype jQuery Yahoo! UI Library (YUI) Mootools Library plug-ins focused specifically on animation or widgets include the following: Script.aculo.us Interface ExtJS Recent additions likely to become popular include the following: base2.DOM DED|Chain Let s discuss each library in more detail to see how it can be used in your next project.

As you can see, the servlet shown in the listing works in a similar manner as the one shown in Listing 9-6 earlier. This time, however, you explicitly persist the Order instances to the database. This is because the @OneToMany annotation used in the Customer entity to define a relationship with the Order entity doesn t set the cascade element anymore. As a result, the persistence provider will no longer cascade any operations performed against a Customer instance to the associated Order instances.
