I am getting this error and I can't figure out why. I believe its the path. Tried to change it several times but no success.

This is a project view.
The login.jsp is inside de jsp package.
change to
<context:component-scan base-package="com.jcg, com.codeEvaluator" />
and your import should be something like this
<import resource="classpath:springBeanConfiguration.xml"/>
or
<import resource="classpath*:springBeanConfiguration.xml"/>
In your "sprinBeanConfiguration.xml" file add those annotations <context:component-scan base-package="com.codeEvaluator" /> and<context:annotation-config> to enable annotation "#Autowired"

it looks like you din't configure data-source in xml file
try to add below configuration in xml file
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/yourdbname" />
<property name="username" value="root" />
<property name="password" value="password" />
</bean>
You need to define DataSource bean in your XML file then only use can use #Autowired annotation to configure that bean or you can use #Autowired annotation in the following way:
#Autowired
private NamedParameterJdbcTemplate jdbcTemplate;
I have written the below code to implment the transaction management of spring using #transactional annotation. I still feel some changes are required
in my DAO layer. May I know what changes are required . Thanks in advance
#Controller
public class RestController {
#Autowired
DataServices dataServices;
#RequestMapping(value = "/v1/dist_list/{emailId}/members", method = RequestMethod.GET)
public #ResponseBody String getDistributionListMember(#PathVariable String emailId) throws Exception, SpringException {
String retStatus = null;
retStatus = dataServices.getDistributionListMember(emailId, callerId);
]
}
}
DataServices.java
package com.uniteid.services;
import com.uniteid.model.AIWSuser;
public interface DataServices {
public String getDistributionListMember(final String emailId, final String callerID) throws Exception;
}
Below is my service layer where I added the trasactional attribute
package com.uniteid.services;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.uniteid.dao.DataDao;
import com.uniteid.model.AIWSuser;
#Service("dataService")
public class DataServicesImpl implements DataServices {
#Autowired
DataDao dataDao;
#Transactional
public String getDistributionListMember(String emailId, String callerID)
throws Exception {
return dataDao.getDistributionListMember(emailId, callerID);
}
}

It still feel I have not implemented the Transactional management properly in the below code. May I know what part of the code can be removed for me to implement it
package com.uniteid.dao;
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Types;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import org.apache.log4j.Logger;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.jdbc.Work;
import org.springframework.beans.factory.annotation.Autowired;
import com.uniteid.controller.RestController;
import com.uniteid.model.AIWSuser;
import com.uniteid.model.User;
public class DataDaoImpl implements DataDao
{
#Autowired
\
SessionFactory sessionFactory;
Session session = null;
Transaction tx = null;
static final Logger logger = Logger.getLogger(DataDaoImpl.class);
public String getDistributionListMember(final String emailId, final String callerID) throws Exception {
session = sessionFactory.openSession();
tx = session.beginTransaction();
final String[] returnVal2 = { "" };
session.doWork(new Work() {
public void execute(Connection connection) throws SQLException {
CallableStatement stmt = null;
String returnVal = "";
stmt = connection.prepareCall("{?=call WS_Distributionlistmember(?,?)}");
stmt.registerOutParameter(1, Types.VARCHAR);
stmt.setString(2, emailId);
stmt.setString(3, callerID);
stmt.execute();
returnVal = stmt.getString(1);
logger.info("RETURN VALUE in getDistributionListMember method :::::: " + returnVal);
returnVal2[0] = returnVal;
logger.info("Return Value " + returnVal);
stmt.close();
}
});
tx.commit();
session.close();
return returnVal2[0];
}
}
Your code:
public String getDistributionListMember(final String emailId, final String callerID) throws Exception {
session = sessionFactory.openSession();//This is bad
tx = session.beginTransaction();//This is bad
tx.commit();//This is bad
session.close();//This is bad
Correct should be:
public String getDistributionListMember(final String emailId, final String callerID) throws Exception {
session = sessionFactory.getCurrentSession();//good way
It is because you told spring to autowired sessionFactory and from now on spring is managing your hibernate session not you. So getCurrentSession() is correct way.
#M. Deinum Thanks to point it out.
Remove bean declaration for bean id transactionManager and set txManager instead of transactionManager in transaction-manager value. As you are using hibernate with spring so HibernateTransactionManager should be used instead of DatabaseTransactionManager to define transaction boundary. DatabaseTransactionManager is used when you directly interact with data source without using any ORM or JPA framework.
In your service class define transaction boundary for method as below annotation
#Transactional(readOnly = true, propagation = Propagation.SUPPORTS)

Looks like component-scan is missing, it helps Spring to detect and instantiate Spring beans which are annotated with #Component, #Service,#Repository, #Controller, #Endpoint etc

For reference : Spring MVC tutorial
My application requires sending a mail from the user entered user name and password using Spring API. Here's how my Application Context file look.
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<context:component-scan base-package="net.mail" />
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="smtp.gmail.com"/>
<property name="port" value="25"/>
<property name="username" value="xyz#xyz.com" />
<property name="password" value="xyz" />
<property name="javaMailProperties">
<props>
<prop key="mail.transport.protocol">smtp</prop>
<prop key="mail.smtp.auth">true</prop>
<prop key="mail.smtp.starttls.enable">true</prop>
<prop key="mail.debug">true</prop>
</props>
</property>
</bean>
</beans>
And my Controller looks like following
package net.mail;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
#Controller
public class MailController
{
#Autowired
MailSender sender;
#ResponseBody
#RequestMapping("/send")
public String sendMailToIt(HttpServletRequest request)
{
try
{
String from=request.getParameter("from");
String to=request.getParameter("to");
String sub=request.getParameter("subject");
String username=request.getParameter("username");
String password=request.getParameter("password");
//username and password should be used for authentication
SimpleMailMessage mail=new SimpleMailMessage();
mail.setFrom(from);
mail.setTo(to);
mail.setSubject(sub);
mail.setText("hello");
sender.send(mail);
}
catch(Exception e)
{
e.printStackTrace();
return "Exception Occured";
}
return new String("mail sent");
}
}
Now my requirements are
I don't want to use the properties file.
I want to username and password to be the ones entered by user.
I only found solutions using the properties file. but in my case i do not want to use that file.
Is there any way of doing so?
You can set in your MailController by getting data from the user ( set or override based on your requirement)
public String sendMailToIt(HttpServletRequest request)
{
.....
JavaMailSenderImpl jMailSender = (JavaMailSenderImpl)sender;
jMailSender.setUsername(userName);
jMailSender.setPassword(password);
....
jMailSender.send(mail);
....
}
