Java - hibernate.cfg.xml File Not Found

There is no /src/main/resources in your built project, that is just where maven keeps the files before building. While building the project (I assume you are building a .jar-artifact) maven will do the following:

1. All .java-files in src/main/java will be compiled to .class-files and will be moved to the subdirectory of the jar corresponding to their package
2. All files from src/main/resources will be copied to the root of the jar-file

So this file-structure in your project:

src
|
+-main
   |
   +-java
   |   |
   |   +- mypackage
   |          |
   |          +- MyClass.java
   |
   +-resources
         |
         +- hibernate.cfg.xml

will end up in your .jar-file like this:

project.jar
|
+- mypackage
|     |
|     +- MyClass.class
|
+- hibernate.cfg.xml

The essential point is: All files from /src/main/resources will end up in the classpath of your built project. But since your configuration-file is named hibernate.cfg.xml and is located on the classpath you should be OK just doing

Configuration conf = new Configuration(); 
conf.configure();

Note that configure() is called wthout an argument, so that means "Look for a file called hibernate.cfg.xml on your current classpath". So try removing the argument from your configure-call.

When using maven with hibernate, one needs only active the shade plugin and hibernate.cfg.xml will go into the right place, such that you can run the file using java -jar jarfile.jar. The stanza you need is something like:

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>2.4.1</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
            <configuration>
              <transformers>
                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                  <mainClass>com.example.jpa.Main</mainClass>
                </transformer>
              </transformers>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

To generate the appropriate uberjar, type mvn package and Bob's your uncle.

First clear one thing that if you are using maven with hibernate so there is no need to define the name of hibernate.cfg.xml in calling configure()

close your project then re-open it use below code to generate session factory you need hibernate 4 or above

public class HibernateUtils {

    private static SessionFactory sessionFactory = null;
    private static Logger logger = Logger.getLogger(HibernateUtils.class.getName());

    public static void createSessionFactory() {

        Configuration configuration = new Configuration().configure();
        StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
                .applySettings(configuration.getProperties());

        try {
            sessionFactory = configuration.buildSessionFactory(builder.build());
        } catch (Exception exe) {
            exe.printStackTrace();
        }

        logger.debug("Session factory created");
    }

    public static SessionFactory getSessionFactory() {

        return sessionFactory;
    }

    public static void shutdown() {

        if (sessionFactory != null)
            getSessionFactory().close();
    }
}

use the following main class for testing purpose

class Main {
    public static void main(String[] args) {
        HibernateUtils.createSessionFactory();
        SessionFactory sessionFactory = HibernateUtils.getSessionFactory();

        // do your  task 

        HibernateUtils.shutdown();
    }
}

Instead of:

configuration.configure("src/main/resources/hibernate.cfg.xml");   

Use:

configuration.configure("/main/resources/hibernate.cfg.xml");  

Keep your config file under normal src directory itself, not to put under resources folder

And refer the file like this Configuration configuration = new Configuration();
configuration.configure("/hibernate.cfg.xml");

//Here i considered configuration class (HibernateSessionFactory.java)is there within the same package

I hope this helps !

If you are sure your file in resources folder then check this Right click on project->Properties->Deployment Assembly and check if your resource file map with Deploy Path or not
