Since i am using hibernate 3.4.0-GA the whole project is annotation based so there are no persistence.xml in my project. The hibernate.cfg.xml file is like this
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.password">password</property>
<!-- <property name="hibernate.connection.url">jdbc:mysql://localhost/apprick_db</property> -->
<property name="hibernate.connection.username">rsingh</property>
<property name="hibernate.connection.password">welcome</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="show_sql">true</property>
<!-- <property name="hbm2ddl.auto">create</property> -->
<mapping class="com.apprick.common.User"></mapping>
<mapping class="com.apprick.common.Customer"></mapping>
<mapping class="com.apprick.common.ApprickAdmin"></mapping>
</session-factory>
</hibernate-configuration>
Now when i run mvn hibernate3:hbm2ddl i get the following exception

Can anyone please suggest me a solution for it. I have been trying to get this done since last two days and its totally driving me crazy.
Thanks for reading the post and i appreciate your inputs.

Answer 1

I hope you figured it out by now. But in case you have not here is a hint:
the part
<componentProperties>
<drop>true</drop>
<configurationfile>src/main/resources/hibernate.cfg.xml</configurationfile>
</componentProperties>
is wrong because you specify the full path
<configurationfile>hibernate.cfg.xml</configurationfile>
is enough, provided the file hibernate.cfg.xml is located in you root Classpath (i.e. WEB-INF/classes)
