Error Missing parameter in call definition: String

Question

I am new to game 2.0. I have created a registration form, and now I am trying to create a search form. But I was caught by this error: " Missing parameter in call definition: String In /home/thangnk/Task/conf/routes at line 17. " .

Here is my code:

CONTROLLER --- Search.java

 package controllers; import java.util.ArrayList; import java.util.List; import models.Task; import play.*; import play.data.Form; import play.db.ebean.Model.Finder; import play.mvc.*; import views.html.*; public class Search extends Controller{ static Form<Task> myform = form(Task.class); public static Result search(){ return ok(search.render()); } public static Result searchByusername(String username){ Form<Task> filledForm = myform.bindFromRequest(); username=filledForm.get().username; return ok(result_search.render(username)); } } 

MODELS --- Task.java

 package models; import java.util.*; import javax.persistence.Entity; import javax.persistence.Id; import play.data.validation.Constraints.Email; import play.data.validation.Constraints.MaxLength; import play.data.validation.Constraints.MinLength; import play.data.validation.Constraints.Required; import play.db.ebean.Model; import play.db.ebean.Model.Finder; @Entity public class Task extends Model { @Id public static Long id; // @Required // @MinLength(6) // @MaxLength(12) public String password; @Email public String email; // @MinLength(6) public String username; public Task() { } public Task(Long id, String username, String email, String password) { this.email = email; this.username = username; this.id = id; this.password = password; } public static Finder<Long, Task> find = new Finder(Long.class, Task.class); public static List<Task> all() { return find.all(); } public static void create(Task task) { task.save(); } public static void delete(Long id) { find.ref(id).delete(); } public static List<Task> searchByusername(String name) { return find.where().like("username", "%" + name + "%").findList(); } } 

ROUTES <i>

Hope guys help me solve this problem and help me fill out this form.

In the routes file, you have inverted the parameter name and enter:

  POST /result_search/:username controllers.Search.searchByusername(username:String)
