    <p>I'm trying to create a simple login based on the Zentask sample --<a href="http://www.playframework.com/documentation/2.2.x/JavaGuide4" rel="nofollow noreferrer">zentask - playframework</a>, however when I click the login button which calls the Application.authenticate actions, it gives runtime exception. I have marked the line with -- error</p> <pre><code>[RuntimeException: java.lang.reflect.InvocationTargetException] </code></pre> <p>Application.java</p> <pre><code>public class Application extends Controller { ......... public static class Login { public String email; public String password; public String validate() { if (User.authenticate(email, password) == null) { return "Invalid user or password"; } return null; } } public static Result authenticate() { Form&lt;Login&gt; loginForm = form(Login.class).bindFromRequest(); //--- error if(loginForm.hasErrors()) { return badRequest(login.render(loginForm)); } else { session("email", loginForm.get().email); return redirect( routes.Application.index() ); } } } </code></pre> <p>I understand it has something to do with the validate function in Login Class, because when I remove the call to User.authenticate in the validate function it works without error. But I am unable to figure it out.</p> <p>The user class is as - </p> <pre><code>@Entity public class User extends Model { @Id @Constraints.Required @Formats.NonEmpty public String userId; @OneToOne(cascade=CascadeType.PERSIST) AccountDetails accDetails; public static Model.Finder&lt;String,User&gt; find = new Model.Finder&lt;String,User&gt;(String.class, User.class); // Authenticate the user details public static User authenticate(String email, String password) { String tempId = AccountDetails.authenticate(email, password).userId; return find.ref(tempId); } .. . . . . . . } </code></pre> <p>and the AccountDetails Class - </p> <pre><code>@Entity public class AccountDetails extends Model { @Id String userId; @Constraints.Required String emailId; @Constraints.Required String password; public static Model.Finder&lt;String,AccountDetails&gt; find = new Model.Finder&lt;String,AccountDetails&gt;(String.class, AccountDetails.class); public static AccountDetails authenticate(String email, String password) { return find.where() .eq("email", email) .eq("password", password) .findUnique(); } } </code></pre>

    1. CONo import declarations, no exception stack trace, fragmental code. It is quite hardcore to answer such question except you already dealt with such problem.

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.
