java - Could not parse configuration: hibernate.cfg.xml caused by org.dom4j.DocumentException: Error on line 2 of document -

i not hibernate , have following problem trying follow tutorial. using hibernate 4

so have client class named helloworldclient:

public class helloworldclient {     public static void main(string[] args) {                  session session = hibernateutil.getsessionfactory().opensession();                 session.begintransaction();                  message message = new message( "hello world hibernate & jpa annotations" );                  session.save(message);                      session.gettransaction().commit();                 session.close();      } } 

as can see class use hibernateutil retrieve hibernate session object, one:

public class hibernateutil {      private static final sessionfactory sessionfactory = buildsessionfactory();      private static sessionfactory buildsessionfactory() {         try {                        // create sessionfactory hibernate.cfg.xml             configuration configuration = new configuration().configure("hibernate.cfg.xml");                  return configuration.buildsessionfactory( new standardserviceregistrybuilder().applysettings( configuration.getproperties() ).build() );         }         catch (throwable ex) {             // make sure log exception, might swallowed             system.err.println("initial sessionfactory creation failed." + ex);             throw new exceptionininitializererror(ex);         }     }      public static sessionfactory getsessionfactory() {         return sessionfactory;     }  } 

and, can see, class use hibernate.cfg.xml configuration file putted root of project, one:

<?xml version='1.0' encoding = 'utf-8'?>  <!doctype hibernate-configuration public     "-//hibernate/hibernate configuration dtd 3.0//en"     "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">  <hibernate-configuration>     <session-factory>          <!-- database connection settings -->          <property name="connection.driver_class">com.mysql.jdbc.driver</property>         <property name="connection.url">jdbc:mysql://localhost:3306/hello-world</property>         <property name="connection.username">root</property>         <property name="connection.password">mypswd</property>          <!--sql dialect -->          <property name = dialect ">org.hibernate.dialect.mysqldialect</property>          <!--use annotation - based mapping metadata -->          <mapping class="entity.message" />      </session-factory> </hibernate-configuration> 

the problem when perform application obtain error message:

info: hhh000040: configuration resource: hibernate.cfg.xml initial sessionfactory creation failed.org.hibernate.hibernateexception: not parse configuration: hibernate.cfg.xml exception in thread "main" java.lang.exceptionininitializererror     @ util.hibernateutil.buildsessionfactory(hibernateutil.java:21)     @ util.hibernateutil.<clinit>(hibernateutil.java:10)     @ client.helloworldclient.main(helloworldclient.java:13) caused by: org.hibernate.hibernateexception: not parse configuration: hibernate.cfg.xml     @ org.hibernate.cfg.configuration.doconfigure(configuration.java:2165)     @ org.hibernate.cfg.configuration.configure(configuration.java:2077)     @ util.hibernateutil.buildsessionfactory(hibernateutil.java:15)     ... 2 more caused by: org.dom4j.documentexception: error on line 2 of document  : non è consentita una destinazione di istruzione di elaborazione corrispondente "[xx][mm][ll]". nested exception: non è consentita una destinazione di istruzione di elaborazione corrispondente "[xx][mm][ll]".     @ org.dom4j.io.saxreader.read(saxreader.java:482)     @ org.hibernate.cfg.configuration.doconfigure(configuration.java:2157)     ... 4 more 

it seems can't read hibernate.cfg.xml file or this.

why? missing ? how can fix issue ?

the mapping document not valid xml. fix line 19:

<property name="dialect">org.hibernate.dialect.mysqldialect</property> 

other shoud work.
