<p>I am struggeling using the basic crud methods with app engine:</p> <p>My code looks like that:</p> <p>My CustomerController:</p> <pre><code>@Controller public class CustomerController { @RequestMapping(value = "/add", method = RequestMethod.GET) public String getAddCustomerPage(ModelMap model) { return "command"; } @RequestMapping(value = "/list", method = RequestMethod.POST) public ModelAndView add(HttpServletRequest request, ModelMap model) { String email = request.getParameter("email"); String password = request.getParameter("password"); Customer c = new Customer(); c.setEmail(email); c.setPassword(password); c.setDate(new Date()); PersistenceManager pm = PMF.get().getPersistenceManager(); try { pm.makePersistent(c); } finally { pm.close(); } return new ModelAndView("redirect:command"); } // get all customers @RequestMapping(value = "/list", method = RequestMethod.GET) public String listCustomer(ModelMap model) { PersistenceManager pm = PMF.get().getPersistenceManager(); Query q = pm.newQuery(Customer.class); q.setOrdering("date desc"); List<Customer> results = null; try { results = (List<Customer>) q.execute(); if (results.isEmpty()) { model.addAttribute("customerList", null); } else { model.addAttribute("customerList", results); } } finally { q.closeAll(); pm.close(); } return "list"; } </code></pre> <p>my mvc-dispatcher-servlet:</p> <pre><code><beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <context:component-scan base-package="com.Trium.controller" /> <mvc:annotation-driven /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="suffix"> <value>.jsp</value> </property> </bean> </code></pre> <p></p> <p>and the form I want to proceede in command.jsp:</p> <pre><code><form id="myForm" class="form-horizontal" action="add" method="post"> <fieldset> <div class="control-group">  <label class="control-label" for="input01">Email:</label> <div class="controls"> <input name="email" placeholder="email" class="input-xlarge" type="text" value="<%=request.getParameter("email")%>"> </div> </div> <div class="control-group">  <label class="control-label" for="input01">Password:</label> <div class="controls"> <input name="password" placeholder="password" class="input-xlarge" type="text" value="<%=request.getParameter("password")%>"> </div> </div> </fieldset> </form> </code></pre> <p>When I want to proceede the form from <code>http://127.0.0.1:8888/command.jsp</code>.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
