Getting Exception while executing hibernate plugin

[Asif Usman]

Hi all,

My name is Asif.

I am trying to Run one simple application using NetBeans IDE, and using Struts frame work with hibernate and MySQL database.
I am getting exection in hibernatePlugin.java while execting _factory = configuration.buildSessionFactory(); statement.

Here below is code of Hibernate.cfg.xml

<?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.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/sampledb</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLMyISAMDialect</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">asif</property>
<property name="connection.pool_size">3</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="show_sql">true</property>
<mapping resource="/Model/test.hbm.xml"/>
</session-factory>
</hibernate-configuration>

code of HibernatePlugin.java

try{

configFileURL = HibernatePlugIn.class.getResource(_configFilePath);
System.out.println("2*************************************");
context = servlet.getServletContext();
configuration = (new Configuration()).configure(configFileURL);
_factory = configuration.buildSessionFactory();
//Set the factory into session
System.out.println("5*************************************");
context.setAttribute(SESSION_FACTORY_KEY, _factory);

}catch(HibernateException e){
e.printStackTrace();
System.out.println("Error while initializing hibernate: " + e.getMessage());
}
System.out.println("*************************************");
}


its giving error and execution will hang when it executes below line

_factory = configuration.buildSessionFactory();

Hello Asif,

Welcome to JavaRanch!

Verify the value of _configFilePath. The error stacktrace doesn't seem to be informative. Why don't you try to isolate the problem? Make a small Java standalone programme and try to get a reference to session factory.

Apart from your problem refer this. http://faq.javaranch.com/java/UseCodeTags . It gives ease in reading the post.
