Exception in thread "main"

looks like it can't find your hibernate config file or the one you are specifying is invalid. can you explain a bit more about what your doing and past in some source files, like your config etc.

Hi,
I guess....
Change doctype in hibernate.cfg.xml,
<<< <!DOCTYPE hibernate-mapping SYSTEM 'hibernate-mapping-3.0.dtd' >
>>> <!DOCTYPE hibernate-configuration SYSTEM 'hbernate-configuration-3.0.dtd' >

Hi,
Thanks but my config file is well formated..i have copied my cfg file..


<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">


<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@ps0560.persistent.co.in:1521:Oracl</property>
<property name="hibernate.connection.username">scott</property>
<property name="hibernate.connection.password">tiger</property>
<property name="show_sql">true</property>
<property name="dialect">org.hibernate.dialect.OracleDialect</property>
<!-- Mapping files -->
<mapping resource="Event.hbm.xml"/>
</session-factory>
</hibernate-configuration>

Hi,
I re-iterate.

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-configuration>

Here,
Doctype Root and DTD : hibernate-mapping
Document Root: hibernate-configuration

You need to correct them.

Hi,
If you are new to hibernate, hibernate docs is a good place to start.
http://www.hibernate.org/hib_docs/v3/re ... l-firstapp

In your case, right now,
i) retain only the correct doctype declaration.
<!DOCTYPE hibernate-configuration SYSTEM 'hbernate-configuration-3.0.dtd' >
ii) Have DTDs in classpath
