Any body help me,regarding hibernate small problem
I am working with hibernarte .I am new to it
when ever i am running hibernate program it is not giving any reply and the values are not updated to the table.
this is my hibernate client file.
import java.io.*;
import javax.servlet.*;

import net.sf.hibernate.HibernateException;
public class HibernateProblem extends GenericServlet{
public void service(ServletRequest req,ServletResponse res)throws ServletException,IOException
{
try {
Configuration conf = new Configuration();
System.out.println("1");
conf.configure(new File("/hibernate.cfg.xml"));
System.out.println("2");
SessionFactory sessionFactory = conf.buildSessionFactory();
System.out.println("3");
Session sess = sessionFactory.openSession();
System.out.println("4");
Cat c=new Cat("x","y");
c.setName("x");
System.out.println(c.getName());
sess.save(c);
System.out.println("5");
sess.flush();
System.out.println("6");
sess.connection().commit();
System.out.println("6");
System.out.println(" ############ " );
} catch (HibernateException hibEx) {
System.out.println( " HibernateException - " + hibEx);
System.out.println(hibEx);
} catch (Exception sqlEx) {
System.out.println(" Exception - " + sqlEx);
}
}
}
and my server.xml contains the database connections as

## the Transaction API abstracts application code from the underlying JTA or JDBC transactions
#hibernate.transaction.factory_class net.sf.hibernate.transaction.JTATransactionFactory
#hibernate.transaction.factory_class net.sf.hibernate.transaction.JDBCTransactionFactory
## to use JTATransactionFactory, Hibernate must be able to locate the UserTransaction in JNDI
## default is java:comp/UserTransaction
## you do NOT need this setting if you specify hibernate.transaction.manager_lookup_class
#jta.UserTransaction jta/usertransaction
#jta.UserTransaction javax.transaction.UserTransaction
#jta.UserTransaction UserTransaction
## to use JCS caching with JTA, Hibernate must be able to obtain the JTA TransactionManager
#hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.JBossTransactionManagerLookup
#hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.WeblogicTransactionManagerLookup
#hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.WebSphereTransactionManagerLookup

## print all generated SQL to the console
#hibernate.show_sql true
## auto schema export
#hibernate.hbm2ddl.auto create-drop
#hibernate.hbm2ddl.auto create
#hibernate.hbm2ddl.auto update
## specify a JDBC isolation level
#hibernate.connection.isolation 4
## set the JDBC fetch size
#hibernate.jdbc.fetch_size 25
## set the maximum JDBC 2 batch size (a nonzero value enables batching)
hibernate.jdbc.batch_size 0
## enable use of JDBC 2 scrollable ResultSets (specifying a Dialect will cause Hibernate to use a sensible default)
#hibernate.jdbc.use_scrollable_resultset true
## use streams when writing binary types to / from JDBC
hibernate.jdbc.use_streams_for_binary true
## use JDBC 3 PreparedStatement.getGeneratedKeys to get the identifier of an inserted row
#hibernate.jdbc.use_get_generated_keys true
## specify a default schema for unqualified tablenames
#hibernate.default_schema test
## use a custom stylesheet for XML generation (if not specified, hibernate-default.xslt will be used)
#hibernate.xml.output_stylesheet C:/Hibernate/net/sf/hibernate/hibernate-default.xslt
## enable outerjoin fetching (specifying a Dialect will cause Hibernate to use sensible default)
#hibernate.use_outer_join false
## set the maximum depth of the outer join fetch tree
hibernate.max_fetch_depth 1
## enable CGLIB reflection optimizer (enabled by default)
#hibernate.cglib.use_reflection_optimizer false
##########################
### Second-level Cache ###
##########################
## optimize chache for minimal "puts" instead of minimal "gets" (good for clustered cache)
#hibernate.cache.use_minimal_puts true
## set a prefix for cache region names
hibernate.cache.region_prefix hibernate.test
## enable the query cache
hibernate.cache.use_query_cache true
## choose a cache implementation

### JNDI ###
############
## specify a JNDI name for the SessionFactory
#hibernate.session_factory_name hibernate/session_factory
## Hibernate uses JNDI to bind a name to a SessionFactory and to look up the JTA UserTransaction;
## if hibernate.jndi.* are not specified, Hibernate will use the default InitialContext() which
## is the best approach in an application server
#file system
