Both of the files are in my resources folder. They seem to be working, but the problem is that my page keeps loading or refreshing without displaying any information when I try to access the database.
I am using jars as follow - hibernate-c3p0 3.6.3.Final, hibernate-core 3.6.3.Final, c3p0 0.9.1.2
Did you try to debug your application to see where is the problem ?
Moreover, it seems to be a little bit excessive to define a timeout of 864 000 ms, isn't it ?

I am trying following JDBC URL and properties but it's not working with autoReconnect=true.

<property name="hibernate.connection.pool_size">10</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.hbm2ddl.auto">update</property>
</properties>
Is there any another way to keep connection?
this got solved my problem.

I am getting the following error when I am using a combination of Spring, Hibernate and SQL Server.
19:17:09,137 ERROR [org.hibernate.tool.hbm2ddl.SchemaValidator] (MSC service thread 1-8) HHH000319: Could not get database metadata: com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host falmumapp20/testdb, port 1433 has failed. Error: "null. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".
It could not be just a TCP IP problem, because if I work without Spring, I am able to connect to SQL Server using hibernate.
Below is my applicationContext.xml

You are not passing database name to the connection url
<property name="url" value="jdbc:sqlserver://falmumapp20:1433;databaseName=testdb" />
or
<property name="url" value="jdbc:sqlserver://falmumapp20:1433/testdb" />
I'm Spring(yfying) my application that uses Hibernate + C3P0 for the connection pool. I'm using a managed hibernate context for specific reasons. I'm using a utility class "HibernateUtil" for Session handling. For the first migration to Spring I am creating an ApplicationContext and retrieving a SessionFactory bean in HibernateUtil replacing the code that used to build the SessionFactory. When I create a session factory bean completely from my old hibernate.cfg.xml in Spring everything works as expected:
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:config/hibernate.cfg.xml"></property>
</bean>
hibernate.cfg.xml

<property name="hibernate.show_sql">true</property>
<property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>

.......
If I externalize the connection pool (I also remove all the connection settings from hibernate.cfg.xml), my transactions do not work properly.
<bean id="myDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="${db.driver}"/>
<property name="jdbcUrl" value="${db.url}"/>
<property name="user" value="${db.user}"/>
<property name="password" value="${db.pass}"/>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="myDataSource"/>
<property name="configLocation" value="classpath:config/hibernate.cfg.xml"></property>
</bean>
I've tried specifying hibernate.transaction.factory_class and moving hibernate properties to Spring bean configuration instead of using hibernate.cfg.xml all to no avail. I cannot completely switch to Spring Transaction management just yet.
Imho you should try to move everything to Spring. In my experience when it is to mixed up there are a lot of problems. Is there a particular reason why you cannot yet set up a spring managed transaction management using:
<!-- Transaction Management -->
<tx:annotation-driven transaction-manager="txManager" proxy-target-class="true"/>
<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
From your description it is quite dificult to find out where exactly the problem is occuring is it with the transactions or with the sessionFactory?
Another point you might be causing your sessionFactory problems when using the dataSource outside of the hibernateProperties is that the ConnectionProvider implementation Hibernate is using is changing. If you specify a dataSource Hibernate will use DataSourceConnectionProvider(http://docs.jboss.org/hibernate/orm/3.6/javadocs/org/hibernate/connection/DatasourceConnectionProvider.html) whereas with setting the data source in the hibernate config Hibernate will use the DriverManagerConnectionProvider (http://docs.jboss.org/hibernate/orm/3.2/api/org/hibernate/connection/DriverManagerConnectionProvider.html)
The differences between these two might be the cause of your problems.

Your hibernate.cfg.xml has the following property:
<property name="hibernate.connection.username">mobeemigrate</property>
But not the corresponding password one:
<property name="hibernate.connection.password">mobeemigrate</property>

Is there a link that has an example?
