Please help me rectify it, so the dropdown is displayed when the view loads.

Your code doesn't even compile because of:
Query q=em.createQuery("select m.mechanicId,m.mechanicType from MechanicEntity m");
List<MechanicEntity> l1=q.getResultList();
The problem is that getResultList() return a List<Object> instead of List< MechanicEntity>.
To make it work:
List<MechanicEntity> l1 = createQuery("select m from MechanicEntity m", MechanicEntity.class).getResultList();

How to config Spring bean for prototype?

I wrote it as a singleton before, there were no errors.
But I think I should make it instance per request.
And I have the code
<!--Dao configuration-->
<bean id="userDao" class="org.mybatis.spring.mapper.MapperFactoryBean" scope="request">
<property name="mapperInterface" value="Dao.UserDao"></property>
<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
</bean>
package Test;
import org.springframework.beans.factory.annotation.Required;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import Common.InitDataBases;
import Common.Controller.OutputStringController;
import Dao.UserDao;
import Model.User;
import java.util.List;
import org.apache.log4j.Logger;
#Controller
#Scope("request")
public class Hello extends OutputStringController{
private UserDao uDao;
#RequestMapping(value = "/getUser", produces = "text/html;charset=UTF-8")
#ResponseBody
public String dbTest(String username) {
System.out.println(uDao.findByUsername(username).getUsername());
return success("");
}
#Required
public void setuDao(UserDao uDao) {
this.uDao = uDao;
}
}
and it threw an exception.

and I can't find a solution for it now.
I would like to make it like : Each http request will create a controller , a service,and a dao.
Help!

you dont need #Scope("request") this,the default is prototype in springmvc

looking at the exception
org.springframework.beans.factory.BeanInitializationException: Property 'uDao' is required for bean 'hello'
uDao is not configured to be injected in to the bean.
Try using
#Autowired
private UserDao uDao;
also make sure if component scan is enabled in the xml configuration.

add custom method to Spring Data JPA

I have created a repository for my entity and I added two methods to it as following :
#Modifying
#Query("UPDATE Offre o SET o.state = 'DISABLED' where o.codeOffre=:x")
void disable(#Param("x") Long offre);
#Modifying
#Query("UPDATE Offre o SET o.state = 'REMOVED' where o.codeOffre=:x")
void remove(#Param("x") Long offre);
Offre entity :
#Entity
public class Offre implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "CODE_OFFRE")
private Long codeOffre;
private String titre;
#Enumerated(EnumType.STRING)
#Column(columnDefinition = "ENUM('ENABLED', 'DISABLED', 'REMOVED') DEFAULT 'ENABLED'")
private State state;
//Getters,Setters
}
and this is my service class :
#Service
public class OffreMetierImpl implements IOffreMetier {
#Autowired
private OffreRepository offreRepository;
#Override
#Modifying
public boolean removeOffre(Long codeOffre) {
offreRepository.remove(codeOffre);
return true;
}
#Override
#Modifying
public boolean disableOffre(Long codeOffre) {
offreRepository.disable(codeOffre);
return true;
}
// Other methods
}
but when I call offreRepository.remove I'm getting this error message :
failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Executing an update/delete query; nested exception is javax.persistence.TransactionRequiredException: Executing an update/delete query] with root cause javax.persistence.TransactionRequiredException: Executing an update/delete query
How can I solve this problem ?

Please make sure that following things are correct at your end.
Your #Modifying annotation should be wrapped up with #Transactional attribute which helps post-processor wraps #Transactional annotated bean methods with an AOP method interceptor which handles transactional behavior.
example
#Modifying
#Transactional
#Query("UPDATE Offre o SET o.state = 'DISABLED' where o.codeOffre=:x")
void disable(#Param("x") Long offre);
Also make sure entries for context:component-scan and

Java BigDecimal validation

Here is property definition
public class Item {
#Digits(integer=6, fraction=2)
#DecimalMin("0.00")
private BigDecimal goods_cost;
and getter/setter
public String getGoods_cost() {
return goods_cost.toString();
}
public void setGoods_cost(String goods_cost) {
this.goods_cost = new BigDecimal(goods_cost);
}
data came from web page
<td><form:input path="goods_cost" type="text" size="10" maxlength="20"/></td>
If input is valid, like 0.01 or 10.15 or 42 everything works fine but if input is invalid, like -10.00 or 12.333 exception generated. There is the exception

Please help! What is wrong with it?

java method can't run in a jsp file

I have a problem.
I have configured in eclipse hibernate with a database in mysql.
I have created a file java, and if I try to save some data to database works perfectly.
The problem is, if I create a jsp file, and try to call the same method it doesn't work, I guess it doesn't connect with hibernate.
public class CreateData {
public int age;
public static void main(String[] args) throws Exception {
SessionFactory sessFact = HibernateUtil.getSessionFactory();
Session session = sessFact.getCurrentSession();
org.hibernate.Transaction tr = session.beginTransaction();
Employee emp = new Employee();
emp.setEmpName("Deepak Kumar");
emp.setEmpMobileNos("000000");
emp.setEmpAddress("Delhi - India");
session.save(emp);
tr.commit();
System.out.println("Successfully inserted");
sessFact.close();
}
public void insert() throws Exception {
SessionFactory sessFact = HibernateUtil.getSessionFactory();
Session session = sessFact.getCurrentSession();
org.hibernate.Transaction tr = session.beginTransaction();
Employee emp = new Employee();
emp.setEmpName("Deepak Kumar");
emp.setEmpMobileNos("000000");
emp.setEmpAddress("Delhi - India");
session.save(emp);
tr.commit();
System.out.println("Successfully inserted");
sessFact.close();
}
public int getAge(){return this.age;}
}
So, if a run the main of this class java ,everything works fine.
but I can't run insert() method in this jsp file (obviously does the some thing as the main )
JSP FILE example:
jsp:useBean id= "user" class= "javabean.CreateData" scope="session"
<% user.getAge();%> // THIS WORKS
<% user.insert();%> // THIS DOESN'T WORK
when I run the jsp gives me an error
