How to connect with hibernate file to SQL server database?

I have a problem because I don't know how to connect to SQL server with hibernate file I try this
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="hibernate.connection.url">jdbc:sqlserver://localhost:1433;databaseName=RentApp</property>
<property name="hibernate.connection.username">LAPTOP-SJJ2BT5V\Konrad</property>
<property name="hibernate.connection.password"></property>

<mapping class="pl.edu.wszib.model.Rent" />
<mapping class="pl.edu.wszib.model.Buy" />
</session-factory>
</hibernate-configuration>
In SQL server my database name is RentApp and I use windows authentication in the Microsoft SQL Server.
So
<property name="hibernate.connection.username">LAPTOP-SJJ2BT5V\Konrad</property>
<property name="hibernate.connection.password"></property>
username must be from Microsoft SQL Server?
And I use in my pom
<!-- https://mvnrepository.com/artifact/com.microsoft.sqlserver/mssql-jdbc -->
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>7.2.2.jre11</version>
</dependency>
I have an error right that but I have username: LAPTOP-SJJ2BT5V\Konrad
com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'LAPTOP-SJJ2BT5V\Konrad'.
I try this
<property name="hibernate.connection.url">jdbc:sqlserver://localhost:1433;databaseName=Test;integratedSecurity=true</property>
But I have error:
com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication.

Hibernate Configration file error

I am new to hibernate framework. i made a sample project just to test hibernate. i set up the project. but when i run it i got this error
org.hibernate.HibernateException: /hibernate.cfg.xml not found
at org.hibernate.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:147)

at org.hibernate.cfg.Configuration.configure(Configuration.java:1414)
at org.hibernate.cfg.AnnotationConfiguration.configure(AnnotationConfiguration.java:966)
The Hibernate.cfg.xml file that i put in the main package of the project.
<?xml version="1.0" encoding="UTF-8"?>

<!-- List of XML mapping files -->

I am using netbeans 7.0

As per DTD, <hibernate-configuration> should have a single <session-factory> but you have declared it twice.
Regarding second error:
org.hibernate.HibernateException: /hibernate.cfg.xml not found
Hibernate looks for the configuration file at the root of the classpath, so check if you have placed this file at root of your classpath.
So once you build your project the hibernate.cfg.xml file should be in classes directory.

Add the following in first line of your xml:
<?xml version="1.0" encoding="UTF-8"?>

Hibernate Mapping Files Not Found(MappingNotFoundException)

I followed this tutorial: http://manikandanmv.wordpress.com/2011/04/13/hibernate-basics-simple-example/
This is my file structure
http://i.stack.imgur.com/sX3nn.jpg
When I run Java Applet, I get this error
Initial SessionFactory creation failed.org.hibernate.MappingNotFoundException: resource: src/com/bookstore/bookapp.hbm.xml not found
However, I have that file there as you can see it. When I put the file under
workspace-windows\226project1\src\com\bookstore
I'm still facing this error even then, Can someone help?
This is my hibernate.cfg.xml
<!DOCTYPE hibernate-configuration PUBLIC

</hibernate-configuration>

Move your mapping files into src/main/resources. Only .java files belong in src/main/java.
There is an example project on github showing how to correctly reference XML mapping files from a hibernate.cfg.xml. Please refer to https://github.com/zzantozz/testbed/tree/master/hibernate-with-xml-mappings

org.hibernate.TransactionException: JDBC rollback failed exception

I'm using Tomcat server, I started it yesterday morning and it continuously runs until this morning, but when I tried to login in my application it shows:
org.hibernate.TransactionException: JDBC rollback failed
What is the problem - is any persistent session here or is sessionfactory null?

I got the problem ,
ie i attached a different jar named c3p0-0.9.1.jar file and add some lines in hibernate-cfg.xml file
The code is :
